Abstract
Description
Technical Field
[0001] The present invention relates to an apparatus for measuring the auditory function of a subject.
Background Art
[0002] When measuring the degree of hearing of a person, a dedicated device such as an audiometer is used (for example, refer to Patent Document 1). For measurement, there are various methods such as air-conduction measurement in which a measurement sound is presented from an air-conduction receiver or earphone, bone-conduction measurement in which a measurement sound is presented from a bone-conduction receiver, and sound field measurement in which a measurement sound is presented from an output device such as a speaker arranged in a soundproof room. The sound presentation devices (air-conduction receivers, earphones, bone-conduction receivers, speakers, etc.) used vary depending on the measurement method.

Summary of the Invention
Problems to be Solved by the Invention
[0004] In each of the above-described measurement methods, the sound presentation device used and its wearing mode and arrangement mode vary depending on the purpose of measurement and the like. For example, even in the same air-conduction measurement, there are cases where an air-conduction receiver is used, and there are also cases where a more suitable earphone (insert type earphone, high-frequency earphone, etc.) is selected and used. The settings of the measurement device differ depending on the device used. In bone-conduction measurement, there are cases where only a bone-conduction receiver is used, and there are also cases where an air-conduction receiver, earphone, or masking receiver is used in combination to mask the non-measured ear. The settings of the measurement device differ depending on which is used in combination. In sound field measurement, the number of speakers used and their arrangement mode vary depending on the type of measurement. In addition, when masking the non-measured ear, the settings of the measurement device also differ accordingly.
[0005] If the wrong type of receiver or earphone is used, or if the speaker is positioned incorrectly, the measurement may need to be repeated. Precise hearing tests are time-consuming, and having to repeat such a test places a significant burden on both the examiner and the subject. Therefore, hearing tests should begin only after the appropriate equipment has been fitted or positioned correctly, and measures are needed to prevent mistakes in equipment use, fitting, or positioning.
[0006] Therefore, the present invention aims to provide a technology that assists in attaching the equipment used for measurement to the subject and arranging it in the measurement room. [Means for solving the problem]
[0007] To solve the above problems, the present invention employs the following auditory measurement device. Note that the following statements in parentheses are merely examples, and the present invention is not limited thereto.
[0008] In other words, the hearing measurement device of the present invention includes an operation reception unit that receives operations for setting up the measurement, and an image display unit that illustrates the positional relationship between one or more sound presenters used for measurement and the head of the subject, according to the content of the settings made via the operation reception unit.
[0009] According to this embodiment of the hearing measurement device, the positional relationship between the sound presenter (handset, earphones, speaker, etc.) to be used in the measurement and the subject's head (where on the subject's head the handset or earphones should be attached and how, and where the speaker should be positioned in relation to the subject) is displayed on the screen. This allows the examiner to refer to this display when attaching the sound presenter to the subject or placing it in the measurement room.
[0010] Preferably, in any of the above-described embodiments of the auditory measurement device, the image display unit displays a front view of how the sound presenter is attached to the subject's head in relation to air conduction measurement or bone conduction measurement. The image display unit also displays the type of sound presenter attached to the subject in a manner that allows for identification.
[0011] According to this embodiment of the hearing measurement device, the schematic diagram of the subject's head displayed on the screen matches how the examiner sees the subject when facing them. Therefore, the examiner can compare the subject they are facing with the display on the screen and attach the sound presenter to the subject in an appropriate manner. In addition, the type of sound presenter to be attached to the subject (e.g., air conduction receiver, in-ear earphone, over-ear earphone, on-ear earphone, bone conduction receiver, masking receiver, etc.) can be identified from the display on the screen, thus preventing the use of the wrong sound presenter.
[0012] Preferably, in any of the above-described embodiments of the auditory measurement device, the image display unit displays a view from above of how the speaker is positioned around the subject's head, in relation to measurements in which the sound presenter includes a speaker. The image display unit also displays the speaker in a manner that allows identification of the type of sound being presented.
[0013] According to this embodiment of the audiometric device, the relative positional relationship between the speaker and the subject, centered on the subject's head, is displayed on the screen. This allows the examiner to compare the layout of the measurement room with the display on the screen and arrange the speaker in an appropriate manner within the room.
[0014] More preferably, in the hearing measurement device according to any of the above embodiments, the image display unit further displays a diagram showing the hearing aid near the ear on which the hearing aid is used when the measurement is performed using the hearing aid.
[0015] According to this embodiment of the audiometric device, when performing measurements using hearing aids (e.g., hearing aids or cochlear implants), a diagram showing the hearing aid near the ear to be used is displayed on the screen. This allows the examiner to attach the sound presenter to the subject, place the sound presenter in the measurement room, and ensure that the hearing aid to be used is properly attached to the appropriate ear.
[0016] More preferably, in the auditory measurement device of any of the above embodiments, the image display unit is capable of displaying in different ways a sound presenter or hearing aid worn by the subject is worn on the right ear and one is worn on the left ear.
[0017] According to this embodiment of the hearing measurement device, the right ear and the left ear may be displayed in different ways (for example, the right ear in red and the left ear in blue), so the examiner can easily confirm whether the sound presenter or hearing aid fitted (or to be fitted) on the subject is correct for the left or right ear.
[0018] Preferably, the auditory measuring device according to any of the above embodiments further includes a status display unit having an area that displays a main figure corresponding to a sound presenter that presents sound to the ear being measured and a sub-figure corresponding to a sound presenter that presents sound to the non-measured ear, in a manner that allows identification of whether the sound presenter corresponding to each figure is currently presenting sound and the destination of the sound being presented.
[0019] According to this embodiment of the auditory measurement device, the examiner can intuitively grasp the current situation regarding sound presentation (which ear is being measured, whether or not sound is being presented) simply by looking at the main and sub-figures on the status display unit.
[0020] More preferably, in the auditory measuring device according to any of the above embodiments, the status display unit further includes a main information area that displays the type, frequency, and presentation level of sound to be presented to the ear being measured, and a sub-information area that displays the type, frequency, and presentation level of sound to be presented to the non-measured ear.
[0021] According to the auditory measurement device of this aspect, by referring to the main information area and the sub information area, the examiner can easily confirm what sounds are currently being presented to the measurement ear and the non-measurement ear.
[0022] More preferably, in the auditory measurement device of any of the above aspects, when making settings related to measurement, the operation reception unit causes a plurality of diagrams substantially equivalent to the diagrams that can be displayed by the image display unit to be displayed on the display as selection candidates, and the content corresponding to the diagram selected from the selection candidates can be set.
[0023] According to the auditory measurement device of this aspect, in the settings related to measurement, since a plurality of diagrams representing the setting content are displayed as selection candidates, compared with the case where selection candidates of character information are displayed, the examiner can easily grasp the content indicated by each selection candidate, can easily make settings related to measurement, and can reduce the burden on the examiner regarding the settings.
Effect of the Invention
[0024] <� As described above, according to the auditory measurement device of the present invention, during measurement, it is possible to prevent mistakes in using the sound presenter or wearing or arranging them in an incorrect manner. The examiner can wear an appropriate receiver, earphone, etc. on the subject in an appropriate manner and arrange the speaker in the measurement room in an appropriate manner.

[Figure 12] Figure (4 / 4) shows examples of various displays in the usage image display unit 13. [Modes for carrying out the invention]
[0026] Embodiments of the present invention will be described below with reference to the drawings. The following embodiments are preferred examples, and the present invention is not limited to these examples. In the following description, the term "measurement" includes the meaning of "examination," "examiner" refers to the person who performs the measurement (measurer), "subject" refers to the person who is measured (subject to measurement), "measurement ear" refers to the ear that is measured (examined ear), "non-measurement ear" refers to the ear that is not measured (non-examined ear), and "measurement sound" refers to the sound presented to the ear that is measured (examination sound).
[0027] [Configuration of the hearing measurement device] Figure 1 shows the configuration of one embodiment of the hearing measurement device 1. Figure 1(A) is a simplified block diagram showing the configuration of the hearing measurement device 1, and Figure 1(B) shows an example of the external appearance of the hearing measurement device 1.
[0028] The hearing measurement device 1 comprises at least a display 10, an operation panel 20, a processor 30, and memory 40. The hearing measurement device 1 is also connected by wire or wirelessly to one or more sound presenters 50 and one or two response buttons 60. The sound presenters 50 are devices capable of outputting sound, such as air conduction receivers, earphones, bone conduction receivers, speakers, or masking receivers, and present measurement sounds, masking sounds, noise, etc., to the subject during measurement. The sound presenters 50 and response buttons 60 can also be considered as part of the hearing measurement device 1.
[0029] The display 10 is equipped with a touch sensor and displays various information related to measurement on its screen, as well as accepting some measurement-related operations via the screen. The screen of the display 10 is provided with a measurement information display unit 11, an operation menu unit 12, a usage image display unit 13, and an input / output status display unit 14.
[0030] Figure 2 shows a magnified example of the screen configuration of display 10. The measurement information display unit 11 displays measurement-related information such as an overview of the measurement, subject information, and audiogram. The operation menu unit 12 displays an operation menu corresponding to some operations of the hearing measurement device 1, and accepts measurement-related operations through this menu. The usage image display unit 13 displays an image diagram of the type of sound presenter 50 used in the measurement and its correct usage from the examiner's perspective (adjusted to the examiner's perspective). The correct usage of the sound presenter 50 specifically refers to the correct way in which the receiver or earphones are attached to the subject, and the correct placement of the speaker relative to the subject; in other words, the correct positional relationship between the sound presenter 50 and the subject. The input / output status display unit 14 displays the sound output status from the sound presenter 50 and the signal input status from the response button 60 (whether or not the subject is pressing the response button 60), etc.
[0031] In the illustrated example, the usage image display unit 13 and the input / output status display unit 14 are both located on the same screen of the display 10, but they may be located on separate displays. The configurations of the usage image display unit 13 and the input / output status display unit 14 will be described in detail later with reference to other drawings.
[0032] Returning to Figure 1, the other components of the auditory measurement device 1 will be described. The control panel 20 consists of a group of buttons and dials that accept operations related to measurement, as well as a group of lamps that indicate the status of the measurement. The group of buttons includes, for example, an inter-lamp button for pausing the presentation of the measurement sound, a provisional threshold button for recording the presentation level of the measurement sound for which the subject has responded in the memory 40, and a threshold button for determining the auditory threshold and recording it in the memory 40. The examiner presses the provisional threshold button when they determine that a valid response has been obtained from the subject, and presses the threshold button when they determine that the current presentation level can be determined as the auditory threshold. The group of dials includes, for example, a level dial for adjusting the presentation level of the sound. The group of lamps also includes, for example, a presentation lamp that lights up when the measurement sound is being presented, and a response lamp that lights up when the subject is pressing the response button 60.
[0033] In the hearing measurement device 1, the main unit corresponds to the ear being measured, and the sub-unit corresponds to the ear not being measured. The elements provided separately for the main and sub-units are arranged such that the main unit's elements are on the left side of the device, and the sub-unit's elements are on the right side. For example, as shown in Figure 1(B), the control panel 20 has two level dials 21. The main level dial 21M is located on the left side, and the sub-level dial 21S is located on the right side.
[0034] The processor 30 controls the progress of the measurement and the display on the display 10 while executing processing according to the operations received by the operation menu unit 12 and the operation panel 20. The memory 40 stores various values obtained during the measurement process.
[0035] When the examiner specifies the frequency and presentation level on the control panel 20, the corresponding measurement sound is presented to the subject from the sound presenter 50 via an amplifier (not shown). The subject presses the response button 60 when they hear the measurement sound and releases the response button 60 when the measurement sound stops. Whether or not the response button 60 is pressed is indicated on the input / output status display unit 14 and the response lamp on the control panel 20. When an indication that the response button 60 has been pressed is made, the examiner checks whether the indication was made while the measurement sound was being presented and, if necessary, observes the subject's reaction to determine whether the response is valid.
[0036] [Configuration of the usage image display section] Figures 3 and 4 show examples of diagrams displayed on the usage image display unit 13. The usage image display unit 13 displays information according to the settings related to the measurement.
[0037] Figure 3 (A-1) shows an example of a diagram displayed during air conduction measurement of the right ear, and Figure 3 (A-2) shows an example of a diagram displayed during air conduction measurement of the left ear. As shown in these diagrams, during air conduction measurement, a schematic diagram of the subject's head viewed from the front is placed in the center, and the sound presenter used for measurement (in the illustrated example, the standard air conduction receiver AC1) is represented as a figure that mimics the actual device, and an image of it being worn by the subject is displayed.
[0038] The schematic diagram of the subject's head corresponds to how it appears when the examiner is facing the subject. The right ear, located on the left side from the examiner's perspective, is fitted with a right-ear sound presenter (in the illustrated example, the right part AC1R of the standard air conduction receiver), and the left ear, located on the right side from the examiner's perspective, is fitted with a left-ear sound presenter (in the illustrated example, the left part AC1L of the standard air conduction receiver). The right-ear sound presenter is represented in red (horizontal hatching in the illustrated example), and the left-ear sound presenter is represented in blue (vertical hatching in the illustrated example). This color coding conforms to the standard for audiological testing equipment (JIS T 1201-1).
[0039] The only difference between the settings for the air conduction measurement that resulted in the display of Figure 3 (A-1) and the settings for the air conduction measurement that resulted in the display of Figure 3 (A-2) is the setting of the measuring ear. In air conduction measurements, it is possible to present the measurement sound to the measuring ear while presenting a masking sound to the non-measurement ear using an air conduction receiver or earphone. Therefore, even when presenting a masking sound, no additional or modified sound presenters are used. Consequently, the displayed figures will be the same even if the setting of the measuring ear changes. From the displays in Figure 3 (A-1) and (A-2), it can be seen that in these air conduction measurements, the subject is fitted with a standard air conduction receiver.
[0040] Figure 3 (B-1) shows an example of a diagram displayed during bone conduction measurement of the right ear, and Figure 3 (B-2) shows an example of a diagram displayed during bone conduction measurement of the left ear. As shown in these diagrams, during bone conduction measurement, a schematic diagram of the subject's head viewed from the front is placed in the center, and the sound presenters used for measurement (in the illustrated examples, the bone conduction receiver BC1 and the masking receiver AC5) are represented by diagrams that mimic the actual devices, and how they appear when worn by the subject is displayed.
[0041] The only difference between the bone conduction measurement settings that resulted in the display of Figure 3 (B-1) and the bone conduction measurement settings that resulted in the display of Figure 3 (B-2) is the setting of the measurement ear. When a masking sound is presented to the non-measurement ear during bone conduction measurement, a sound presenter is used for this purpose. As shown in the example, when the bone conduction receiver is attached to the mastoid, the masking receiver is attached to the non-measurement ear. However, when the setting of the measurement ear changes, the usage image display unit 13 displays a diagram in which the positions of the bone conduction receiver and the masking receiver are reversed left to right, while the orientation of the head remains the same. From the displays in Figure 3 (B-1) and (B-2), it can be seen that in these bone conduction measurements, the bone conduction receiver is attached to the mastoid on the measurement ear side of the subject, and the masking receiver is attached to the non-measurement ear.
[0042] In contrast, as shown in Figures 3(B-3) and (B-4), when the bone conduction receiver is attached to the forehead, a bilateral air conduction receiver or earphone (standard air conduction receiver AC1 in the illustrated example) can be used in combination to present a masking sound. When these are used in combination, the displayed diagram will be the same even if the setting of the measurement ear changes. From the displays in Figures 3(B-3) and (B-4), it can be seen that in these bone conduction measurements, the bone conduction receiver is attached to the forehead of the subject, and standard air conduction receivers are attached to both ears.
[0043] Figure 4 (C-1) is an example of a diagram displayed during sound field measurement of the right ear, and Figure 4 (C-2) is an example of a diagram displayed during sound field measurement of the left ear. Figure 4 (D-1) is an example of a diagram displayed during hearing measurement of an infant with the right ear, and Figure 4 (D-2) is an example of a diagram displayed during hearing measurement of an infant with the left ear. Figure 4 (E-1) is an example of a diagram displayed during speech measurement under noise of the right ear, and Figure 4 (E-2) is an example of a diagram displayed during speech measurement under noise of the left ear.
[0044] As shown in the figures in Figure 4, for sound field measurement, infant hearing measurement, and speech sound measurement under noise, a schematic diagram of the subject's head viewed from above is placed in the center. The schematic diagram of the head shows the shape of both ears and nose, so the direction the subject is facing can be identified from the positions of these. In addition, the sound presenters placed in the measurement room (speakers SP1 and SP2 in the illustrated example) are displayed in a manner that allows identification of the type of sound they present (speaker SP1 presents the measurement sound, speaker SP2 presents noise), and the positional relationship between these sound presenters and the subject is clearly indicated. Furthermore, the subject is shown wearing the hearing aids and sound presenters used in the measurement (hearing aids HAR and HAL and masking receiver AC5 in the illustrated example).
[0045] The only difference between the settings for the sound field measurement that resulted in the display of Figure 4 (C-1) and the settings for the sound field measurement that resulted in the display of Figure 4 (C-2) is the setting of the ear being measured. From the displays in Figure 4 (C-1) and (C-2), it can be seen that in these sound field measurements, one speaker is placed in front of the subject to present the measurement sound, and a hearing aid is worn on the subject's measurement ear, while a masking hearing aid is worn on the non-measurement ear.
[0046] The only difference between the settings for the infant hearing test that resulted in the display of Figure 4 (D-1) and the settings for the infant hearing test that resulted in the display of Figure 4 (D-2) is the setting of the ear being measured. From the displays in Figure 4 (D-1) and (D-2), it can be seen that in these infant hearing tests, one speaker is placed on each side in front of the subject to present the measurement sound, and a hearing aid is fitted to the subject's ear being measured.
[0047] The only difference between the settings for noise-based speech measurement that resulted in the display of Figure (E-1) in Figure 4 and the settings for noise-based speech measurement that resulted in the display of Figure (E-2) in Figure 4 is the setting of the measurement ear. From the displays in Figures (E-1) and (E-2) in Figure 4, it can be seen that in these noise-based speech measurements, one speaker is placed in front of the subject to present the measurement sound, and one speaker is placed to the right of the subject to present the noise, and a hearing aid is worn in the subject's measurement ear.
[0048] In this way, the usage image display unit 13 displays, in accordance with the settings made for the measurement, which sound presenter will be used in the measurement and in what manner it will be attached or positioned (the correct positional relationship between the sound presenter and the subject's head), in a manner that is aligned with the examiner's viewpoint. Therefore, the examiner can face the subject and compare the subject with the usage image display unit 13 to confirm whether the type of receiver or earphone used for the measurement and how it is attached is correct. If it is incorrect, the examiner can readjust it so that it matches the display on the usage image display unit 13, thereby attaching the receiver or earphone to the subject in the correct manner. In addition, the examiner can compare the layout of the measurement room with the usage image display unit 13 to confirm whether the speaker placement is correct. If it is incorrect, the examiner can readjust it so that it matches the positional relationship shown on the usage image display unit 13, thereby placing the speaker in the measurement room in the correct manner. Specific examples of measurement setting items will be described later using separate diagrams.
[0049] Figure 5 shows various shapes of sound presenters and hearing aids that may be displayed on the usage image display unit 13. In other words, the shapes of sound presenters that may be displayed on the usage image display unit 13 are shapes that mimic sound presenters that can be connected to the hearing measurement device 1.
[0050] Figure 5(A) shows variations in shapes that mimic a receiver or earphone used to present air-conducted sound. The auditory measurement device 1 can be connected to, for example, a standard air-conducted receiver, an in-ear earphone, a high-frequency earphone (over-ear earphone), a top-of-ear earphone, and a single-ear masking receiver, and shapes that mimic these, such as standard air-conducted receiver AC1, in-ear earphone AC2, high-frequency earphone AC3, top-of-ear earphone AC4, and masking receiver AC5, may be displayed. Of these shapes, the part for the right ear, whose code ends in "R", is represented in red (horizontal hatching in the illustrated example), and the part for the left ear, whose code ends in "L", is represented in blue (vertical hatching in the illustrated example).
[0051] Figure 5(B) shows variations in the shape of the bone conduction receiver. Although only one type of bone conduction receiver can be connected to the hearing measurement device 1, two shapes are provided to match the appearance to the examiner, as the appearance differs depending on where the bone conduction receiver is attached. Specifically, when the bone conduction receiver is attached to the mastoid area, bone conduction receiver BC1, which mimics how it looks when attached to the mastoid area, is displayed, and when the bone conduction receiver is attached to the forehead area, bone conduction receiver BC2, which mimics how it looks when attached to the forehead area, is displayed.
[0052] Figure 5(C) shows variations of speaker-like shapes. Multiple shapes are available for speakers depending on the type of sound being presented. For example, speaker SP1 is displayed, representing a speaker that presents a measurement sound, with three concentric arc shapes gradually expanding in front of it. Speaker SP2 is displayed, representing a speaker that presents noise, with three zigzag shapes arranged in front of it. Speaker SP3 is displayed, representing a speaker that presents both measurement sound and noise, with three arc shapes in front of it and three zigzag shapes superimposed on the arc shapes. In addition, in measurements using speakers, there may be cases where multiple speakers are placed in the measurement room, but one of the speakers is not used (no sound is presented from that speaker). In such cases, speaker SP4 is displayed, representing only the speaker itself.
[0053] Figure 5(D) shows a diagram resembling a hearing aid. The HAL hearing aid, represented in blue (vertical hatching in the example shown), corresponds to the hearing aid for the left ear, and the HAR hearing aid, represented in red (horizontal hatching in the example shown), corresponds to the hearing aid for the right ear.
[0054] Thus, the usage image display unit 13 displays shapes of receivers and earphones in a manner that allows for identification of their type, enabling the examiner to attach the correct device to the subject while referring to the display. In addition, the usage image display unit 13 displays speaker shapes in a manner corresponding to the type of sound they produce, making it easy to understand what kind of sound is produced (or not produced) from each speaker.
[0055] In the illustrated examples, air conduction receivers, earphones, and hearing aids are shown in red for the right ear and in blue for the left ear. However, along with or instead of these indications, letters that distinguish between right and left ear devices may be added. For example, the right ear device may be labeled with the small letters "Right" or "R," and the left ear device with the small letters "Left" or "L."
[0056] [Configuration of the Input / Output Status Display Unit] Figure 6 shows an example of the display in the input / output status display unit 14. Figure 6(A) shows the legend for the input / output status display unit 14. The input / output status display unit 14 is broadly divided into three areas. On the left side of the input / output status display unit 14, text information regarding the output of the main (measured ear) is displayed in three lines. On the right side, text information regarding the output of the sub (non-measured ear) is displayed in three lines. In the center, the sound output status for the main and sub, and the signal input status from the response button 60 are displayed graphically.
[0057] More specifically, the first line of the main display shows the type of main sound on the left and its frequency on the right. The second line of the main display shows the main sound level. The third line of the main display shows the sound presenter corresponding to the measurement method on the left and the ear being measured on the right. Additionally, the first line of the sub-display shows the type of sub-sound on the left and its frequency on the right. The second line of the sub-display shows the sub-sound level. The third line of the sub-display shows whether masking is being performed on the left and the non-measured ear on the right. Masking of the non-measured ear is performed when the difference between the air conduction hearing level of the measured ear and the bone conduction hearing level of the non-measured ear is close to or exceeds the bilateral transition attenuation (the amount of attenuation when sound given to one ear reaches the inner ear of the other ear).
[0058] Furthermore, four shapes are arranged in the center of the input / output status display unit 14. From left to right, the four shapes are: presentation diagram Mp corresponding to the main sound presenter, response diagram Ma corresponding to the main response button, response diagram Sa corresponding to the sub response button, and presentation diagram Sp corresponding to the sub sound presenter. Presentation diagrams Mp and Sp are displayed in an active state and color corresponding to the ear to which the sound is presented when the corresponding sound presenter is presenting sound, while they are displayed in an inactive state when no sound is being presented. Similarly, response diagrams Ma and Sa are displayed in an active state when the corresponding response button is pressed, and in an inactive state when it is not pressed.
[0059] Specifically, the inactive state refers to a state where the indicator is grayed out. In Figure 6, the active state is shown with a solid line, and the inactive state is shown with a dashed line. In addition, red is indicated by horizontal hatching, and blue is indicated by vertical hatching. For the sake of explanation, in Figure 6, all response diagrams Ma and Sa are shown in the inactive state. The following will explain using specific examples.
[0060] Figure 6(B) shows an example of a display when masking is performed during air conduction measurement of the right ear. For example, from the third line of the main display in Figure 6(B), it can be seen that the right ear is the measurement ear for air conduction measurement, and from the third line of the sub-display, it can be seen that masking is performed on the left ear, which is the non-measurement ear. Corresponding to this information, the main display diagram Mp is displayed in a red active state, and the sub-display diagram Sp is displayed in a blue active state.
[0061] Figure 6(C) shows an example of the display when masking is not performed during air conduction measurement of the left ear. For example, from the third line of the main display in Figure 6(C), it can be seen that the left ear is the measurement ear for air conduction measurement, and from the first and third lines of the sub-display, it can be seen that masking is not performed for the right ear, which is the non-measurement ear. Corresponding to this information, the main display diagram Mp is displayed in a blue active state, and the sub-display diagram Sp is displayed in an inactive state.
[0062] Figure 6(D) shows an example of a display when masking is performed during bone conduction measurement of the left ear. For example, from the third line of the main display in Figure 6(D), it can be seen that the bone conduction measurement is performed with the left ear as the measurement ear, and from the third line of the sub-display, it can be seen that masking is performed on the right ear, which is the non-measurement ear. Corresponding to this information, the main display diagram Mp is displayed in a black, active state with a figure resembling a bone conduction receiver, and the sub-display diagram Sp is displayed in a red, active state.
[0063] Figure 6(E) shows an example of a display when noise is not presented during a bilateral sound field measurement. For example, from the third line of the main section in Figure 6(E), it can be seen that the sound field measurement is performed with both ears as the measurement ears, and from the first and third lines of the sub-section, it can be seen that masking is not performed on the non-measurement ear. This is also clear from the fact that both ears are the measurement ears. Corresponding to this information, the main presentation diagram Mp is displayed in an active state in pink (hatching with vertical and horizontal lines in the example shown) to indicate the presentation of sound to both ears.
[0064] As described above, the input / output status display unit 14 concisely displays information about the main and sub outputs (type of sound source, frequency, presentation level) in text during measurement. In addition, the central presentation diagrams Mp and Sp become active when the corresponding sound presenter is presenting sound, and when air conduction sound is being presented, they are displayed in a color corresponding to the ear to which the sound is being presented (red for the right ear, blue for the left ear, and pink for both ears). The response diagrams Ma and Sa become active when the corresponding response button is pressed. Therefore, the examiner can intuitively grasp the current status (which ear is being measured, whether or not sound is being presented, and whether or not the subject is responding) from the display content of the input / output status display unit 14, and can easily confirm what kind of sound is currently being presented on the main and sub sides.
[0065] The illustrated example is merely one example, and the display may be presented in a different manner. For example, in Figure 6(D), the main display diagram Mp for bone conduction measurement shows a figure resembling a bone conduction receiver in black and in an active state. However, instead of displaying this figure in black, it may be color-coded in red or blue depending on whether the measurement ear is the right or left ear.
[0066] [Measurement Procedure] Figure 7 is a flowchart showing the measurement process using the auditory measurement device 1. The following describes the procedure for measuring hearing in one ear.
[0067] Step S10: Preparation for measurement is made. In preparing for measurement, the examiner makes settings related to the measurement to be performed via the operation menu section 12 of the display 10 or the operation panel 20. First, the examiner selects a measurement method, and the setting items corresponding to the selected measurement method are displayed on the display 10.
[0068] Figure 8 shows specific examples of setting items depending on the measurement method. Air conduction measurement is performed by presenting a measurement sound through an air conduction receiver or earphone worn by the subject. For air conduction measurement, settings such as the type of air conduction receiver or earphone to be used, the ear to be measured (right or left), and boost (ON or OFF) are configured.
[0069] Bone conduction measurement is performed by presenting a measurement sound through a bone conduction receiver worn on the subject. For bone conduction measurement, settings such as bone conduction conditions (with or without frontal closure correction, or mastoid open), whether or not an air conduction receiver or masking receiver is used in combination, the type of air conduction receiver or masking receiver used (if used in combination), and the ear being measured (right ear or left ear) are specified.
[0070] Sound field measurement is performed by arranging one or two speakers side-by-side in a measurement room and presenting a measurement sound and noise from the speakers. In sound field measurement, hearing aids may or may not be worn, and a masking receiver may be attached to the ear not being tested. In addition, there are cases where only the measurement sound is presented from the speakers, where the measurement sound is presented from one speaker and noise from the other, or where the measurement sound and noise are output together from a single speaker. Settings for sound field measurement include the number of speakers used (either one or two), the presentation method of the measurement sound and noise (which speaker presents the measurement sound and which presents the noise, or whether the measurement sound and noise are output together from a single speaker), the types of measurement sound and noise, the ear being tested (right ear, left ear, or both), whether or not a hearing aid is used, and whether or not a masking receiver is used.
[0071] Among the various methods of measuring hearing in infants, the COR (conditional orientation audiometry) is particularly important. This method involves placing speakers on the left and right sides in front of the subject and measuring their hearing by observing their reactions to the sound and the lights that illuminate. For COR, settings such as which ear to measure (right ear, left ear, or both) and whether or not they use hearing aids are specified.
[0072] Noise-based speech measurement is conducted in a soundproofed measurement room, with multiple speakers positioned at 90-degree angles to the subject (in the case of three speakers, they are positioned in front of the subject and to the left and right; in the case of two speakers, they are positioned in front of the subject and to either the left or right), and the subject is presented with both a measurement sound and noise. Noise-based speech measurement can be performed with or without hearing aids. Settings for noise-based speech measurement include the speaker arrangement, the type of sound (measurement sound, noise) presented from each speaker, the ear being measured (right ear, left ear, or both), and whether or not hearing aids are used.
[0073] As the examiner sets these settings according to the measurement method, the usage image display unit 13 displays information corresponding to the settings. The examiner then attaches the sound presenter to the subject and places it in the measurement room, referring to the information displayed on the usage image display unit 13. After confirming that the correct type of sound presenter is being used, and that the way the sound presenter is attached to the subject and placed in the measurement room is correct, the examiner proceeds to the next step. The following describes the procedure from step S20 onward, returning to Figure 7.
[0074] Step S20: A preliminary measurement is performed. In the preliminary measurement, a 1000Hz measurement sound is first presented at 40dB. If the subject responds to the 40dB presentation (or if they appear to hear it, in the case of infants, etc.), the presentation level is lowered in 10-20dB steps until there is no response. On the other hand, if there is no response, the presentation level is raised in 10-20dB steps until a response is obtained, and then the presentation level is lowered in 10-20dB steps until there is no response. Once there is no response, the presentation level is raised in 5dB steps until a response is obtained, and then fixed at the level at which a response was obtained or 5dB above it. The presentation and pause of the measurement sound are repeated several times using the interrupter button. If the response generally matches the presentation pattern of the measurement sound, the preliminary measurement is completed, and the presentation level at this point becomes the auditory threshold for the preliminary measurement.
[0075] Next, the main measurement will begin. Step S30: First, the examiner sets the initial measurement frequency. Generally, air conduction hearing tests are performed in the order of 1000Hz → 2000Hz → 4000Hz → 8000Hz → 1000Hz → 500Hz → 250Hz → 125Hz, while bone conduction hearing and sound field threshold tests are performed in the order of 1000Hz → 2000Hz → 4000Hz → 1000Hz → 500Hz → 250Hz. The reason for performing the 1000Hz measurement twice, once at the beginning and once in the middle, is to confirm the validity of the response.
[0076] Therefore, generally, "1000Hz" is set as the initial measurement frequency. However, since this frequency is the same as the frequency used in the preliminary measurement, step S30 can be omitted if the main measurement is started at "1000Hz" immediately after the preliminary measurement. Note that the measurement frequencies and their order are not limited to those described above, and measurement frequencies may be added or removed, or their order may be changed, as needed.
[0077] Steps S32-S36: The test sound is presented at a level 10-20 dB lower than the auditory threshold level obtained in the preliminary measurement (Step S32). If no response is received (Step S34: No), the presentation level is increased by 5 dB (Step S36), and the presence or absence of a response is checked again. This process of increasing the presentation level in 5 dB steps continues until a response is received. If a response is received, the validity of the response is also checked. If it cannot be determined to be a valid response, steps S34 and S36 are repeated. The presentation level can be adjusted by the examiner using the level dial 21, or it can be done automatically by the processor 30.
[0078] Step S38: If the examiner determines that this is a valid response (Step S34: Yes), the examiner presses the provisional threshold button. Consequently, the current presentation level is recorded in memory 40 as a provisional auditory threshold (hereinafter abbreviated as "provisional threshold"), and the display on display 10 is updated, with a symbol indicating this provisional threshold added to the audiogram displayed on the screen.
[0079] Steps S40-S44: The presentation level is increased by 5-10 dB, and after a certain period of time, it is decreased by 10-20 dB (Step S40). This makes the measured sound lower than the presentation level at which a response was obtained (= latest provisional threshold). If no response is obtained here (Step S42: No), the presentation level is increased by 5 dB (Step S44), and the presence or absence of a response is checked again, and so on, increasing the presentation level in 5 dB steps until a response is obtained. If a response is obtained, the validity of that response is also checked, and if it cannot be determined to be a valid response, steps S42 and S44 are repeated.
[0080] Step S46: If the examiner determines that this is a valid response (Step S42: Yes), the examiner presses the provisional threshold button. Consequently, the current presentation level is recorded in memory 40 as a new provisional threshold, and the display on display 10 is updated, with a symbol indicating the newly recorded provisional threshold added to the audiogram displayed on the screen.
[0081] Steps S48, S50: The processor 30 checks whether the provisional threshold recorded in the previous step S50 has reached a majority of the provisional thresholds recorded so far, i.e., multiple provisional thresholds obtained from multiple measurements (Step S48). If it has reached a majority (Step S48: Yes), the processor 30 updates the display on the display 10, changing the display of the provisional threshold to notify the examiner that a majority has been reached. After a few seconds, the processor 30 confirms the provisional threshold that has reached a majority as the auditory threshold for the current measurement frequency and records it in the memory 40, and updates the display on the display 10 again. As a result, the display of the provisional threshold is erased from the audiogram displayed on the screen, and a symbol indicating the auditory threshold is added (Step S50). On the other hand, if it has not reached a majority (Step S48: No), the examiner returns to step S40 and performs the measurement again.
[0082] For example, if the same provisional threshold is recorded in the first measurement (steps S32-S38) and the second measurement (steps S40-S46), a majority has been reached (step S48: Yes), so the process proceeds to step S50, and this provisional threshold is confirmed as the auditory threshold. On the other hand, if different provisional thresholds are recorded in the first and second measurements, a majority has not been reached (step S48: No), so the process returns to step S40 and a third measurement is performed.
[0083] Then, if the provisional threshold recorded in the third measurement (steps S40-S46) is the same as either the first or second provisional threshold, a majority has been reached (step S48: Yes), and the process proceeds to step S50, where this provisional threshold is confirmed as the auditory threshold. On the other hand, if the provisional threshold recorded in the third measurement is different from either the first or second provisional threshold, a majority has not been reached (step S48: No), and the process returns to step S40 for the fourth measurement. The measurement is then repeated in the same procedure until the newly recorded provisional threshold reaches a majority of the number of provisional thresholds recorded up to that point, or in other words, until the number of times the same provisional threshold as the new provisional threshold has been obtained reaches a majority of the total number of measurements. Alternatively, instead of repeating the measurement until a majority of the total number of measurements is reached, it may be repeated until a majority of the most recent three measurements are reached.
[0084] Step S52: Once the auditory threshold is determined, increase the presentation level by 5-10 dB, and after a certain period of time, reduce it to a level that is likely to be inaudible to the subject.
[0085] Steps S54-58: If there are any unmeasured frequencies remaining (Step S54: Yes), the examiner sets the next measurement frequency (Step S56). Accordingly, all provisional thresholds recorded in memory 40 are cleared (Step S58). Then, the process returns to step S32 and measurements are taken for the next measurement frequency.
[0086] Conversely, if there are no unmeasured frequencies remaining, that is, if measurements for all frequencies have been completed (Step S54: No), the measurement of one ear is finished. Following this, the measurement of the other ear is performed in the same manner as described above.
[0087] The above procedure is merely an example and can be modified as needed. For example, the examiner may press the threshold button at any point to set the current presentation level as the auditory threshold, regardless of the provisional thresholds currently stored in memory 40. In this case, pressing the threshold button sets the auditory threshold and clears all provisional thresholds stored in memory 40.
[0088] [Various display examples of the usage image display section] Figures 9 to 12 show excerpts of various displays in the usage image display unit 13. Below, the content of the displays will be explained in detail for each measurement method.
[0089] Figure 9(A) shows an example of the display shown on the usage image display unit 13 during air conduction measurement. When earphones are used, the model number is displayed in addition to a diagram resembling earphones. This display allows the examiner to easily confirm whether the earphones attached to the subject match the set earphones. In addition, if the boost (a function that increases the output to a certain level) is "ON", this fact is also displayed. This display allows the examiner to easily recognize that the boost is ON. Note that the boost cannot be used with the on-ear earphones in the illustrated example, so there is no display example for when the boost is ON (the settings for air conduction measurement are configured so that it is not possible to combine these on-ear earphones with the boost ON setting).
[0090] Figure 9(B) shows an example of the display on the usage image display unit 13 during bone conduction measurement. When earphones are used in conjunction with bone conduction measurement, the model number is displayed in addition to a figure resembling earphones (the model number is not displayed when a standard air conduction receiver or masking receiver is used). This display allows the examiner to easily confirm whether the earphones attached to the subject match the set earphones. Furthermore, if the bone conduction condition is "with frontal closure correction" or "without frontal closure correction," whether or not the external auditory canal closure effect is corrected is also displayed. This display allows the examiner to easily recognize whether or not the external auditory canal closure effect is corrected when the bone conduction receiver is attached to the subject's forehead.
[0091] Figure 10(C) shows an example of the display shown on the image display unit 13 during sound field measurement. In Figure 10(C), an example of the display when the measurement ear is the "left ear" is not shown, but when the measurement ear is the "left ear", the display is the same as the display example when the measurement ear is the "right ear", with the equipment worn on the subject reversed left and right (the same applies to other measurements described later). For example, if the sub-output destination is a "masking receiver", the measurement ear is the "left ear", and a hearing aid is "present", the display is the same as the display when the measurement ear is the "right ear" and a hearing aid is "present", with the equipment worn on the subject (left ear: masking receiver, right ear: hearing aid for the right ear) reversed left and right, that is, a diagram is displayed showing a left-ear hearing aid worn on the left ear and a masking receiver worn on the right ear.
[0092] Furthermore, in Figure 10 (C), the illustration of the display example when the sub-output destination is a speaker and "Output Method 2" or "Output Method 4" is selected as the output method is omitted. When "Output Method 2" is selected, the display is the same as the display example for "Output Method 1" with the output from the two speakers (left speaker: measurement sound, right speaker: noise) reversed left and right, that is, a diagram is displayed in which noise is output from the left speaker and the measurement sound is output from the right speaker. Also, "Output Method 3" outputs the sound of the main channel and sub-channel from the main speaker, while "Output Method 4" outputs the sound of the main channel and sub-channel from the sub speaker, and both are common in that the measurement sound and noise are output from a single speaker. Therefore, when "Output Method 4" is selected, the display is the same as when "Output Method 3" is selected.
[0093] Figure 10(D) shows an example of the display shown on the usage image display unit 13 in COR as an example of a display in infant hearing measurement. As shown in Figure 10(C), non-test ears are not masked in COR. However, in infant hearing measurement, non-test ears may be masked depending on the situation in play hearing measurement. Therefore, in the settings for play hearing measurement, it is possible to set whether or not to use a masking receiver. If the setting to use a masking receiver is made in play hearing measurement, a diagram showing the non-test ear with the masking receiver attached will be displayed accordingly.
[0094] Figure 11(E) shows an example of the display shown on the image display unit 13 during direction perception measurement. In direction perception measurement, a diagram is displayed showing two speakers placed side by side in front of the subject, with measurement sounds being output from these speakers.
[0095] Figure 11 (F-1) shows an example of the display on the usage image display unit 13 when "Speaker Arrangement 1" is selected as the speaker arrangement for noise-induced speech sound measurement, i.e., when two speakers are used for noise-induced speech sound measurement. In both displays, the display is shown in a manner in which the measurement sound is output from the speaker located in front of the subject. Figure 12 (F-2) shows an example of the display on the usage image display unit 13 when "Speaker Arrangement 3" is selected as the speaker arrangement for noise-induced speech sound measurement, i.e., when three speakers are used for noise-induced speech sound measurement.
[0096] Between Figure 11 (F-1) and Figure 12 (F-2), the illustration of the display example when "Speaker Arrangement 2" is selected as the speaker arrangement is omitted. When "Speaker Arrangement 2" is selected, a diagram is displayed showing the arrangement in which the speaker that is located on the left side of the usage image display unit 13 in the display when "Speaker Arrangement 1" is selected has been moved to the right side of the usage image display unit 13.
[0097] [Advantages of the present invention] As described above, the following effects can be obtained using the auditory measurement device 1 mentioned above.
[0098] (1) In the center of the usage image display unit 13, for air conduction and bone conduction measurements, a schematic diagram of the subject's head viewed from the front, i.e., a schematic diagram that looks the same as when the examiner is facing the subject, is placed, and in measurements using a speaker, a schematic diagram of the subject's head viewed from above is placed, and the sound presenter to be used, such as a receiver or earphone, is represented as a figure that mimics the actual object, corresponding to the settings related to the measurement, and the image of it being worn on the subject is displayed, so that the examiner can easily check whether the type of sound presenter being worn is appropriate (whether the wrong sound presenter is being worn, whether all the necessary ones are being worn), and whether the sound presenter is being worn properly (whether it is being worn in the wrong position, etc.) by comparing the subject with the usage image display unit 13 during the process of preparing for the measurement, and if it is not appropriate, the sound presenter can be worn on the subject in an appropriate manner by readjusting it to match the display on the usage image display unit 13.
[0099] (2) In measurements using a speaker, a schematic diagram of the subject's head viewed from above is placed in the center of the usage image display unit 13, corresponding to the settings related to the measurement, and the arrangement of the speaker in the measurement room (the relative positional relationship between the speaker and the subject) is also displayed. Therefore, during the process of preparing for the measurement, the examiner can easily check whether the speaker arrangement and the orientation of the subject relative to the speaker are appropriate by comparing the layout of the measurement room with the usage image display unit 13. If they are not appropriate, the examiner can first check whether the settings they have made are correct, and if the settings are correct, they can check the layout of the room and rearrange the speakers so that the positional relationship is the same as that displayed on the usage image display unit 13, thereby positioning the speaker in an appropriate manner in the measurement room.
[0100] (3) In the process of preparing for measurement, by referring to the usage image display unit 13, various sound presenters (handset, earphones, speaker, etc.) to be used for measurement can be attached to the subject in an appropriate manner and arranged in the measurement room in an appropriate manner. This reduces the possibility of starting the measurement with the wrong type of sound presenter or incorrect attachment or arrangement, and the possibility of having to repeat the measurement as a result.
[0101] (4) The input / output status display unit 14 has a display diagram Mp corresponding to the main sound presenter and a display diagram Sp corresponding to the sub sound presenter located in the center. The display diagrams become active when the corresponding sound presenter is presenting sound and are displayed in a color corresponding to the ear being presented to (red for one ear, blue for the left ear, and pink for both ears). This allows for an intuitive understanding of which ear is currently being measured and whether sound is being presented, thereby reducing the burden on the examiner during measurement.
[0102] The present invention can be implemented in various ways without being limited to the embodiments described above.
[0103] In the embodiment described above, the way the receiver, earphones, etc. used for measurement are worn by the subject, and the arrangement of the speaker, etc., as seen in relation to the subject, are displayed on the usage image display unit 13. However, the content displayed on the usage image display unit 13 may be divided and displayed on multiple display units, for example, by displaying the way the receiver, earphones, etc. are worn on the first display unit and the arrangement of the speaker on the second display unit. Furthermore, these divided multiple display units may be provided on a single screen or on separate screens.
[0104] In the embodiment described above, the measurement items shown in Figure 8 are set by selecting the corresponding text information from the displayed selection candidates using the operation menu unit 12 or the operation panel 20. However, instead of displaying the selection candidates as text information, the selection candidates may be displayed as diagrams that simply show the setting content, and the setting may be made by tapping (touching to select) the corresponding diagram or by selecting the diagram using the buttons on the operation panel 20.
[0105] For example, when setting the measurement method, the system may display a schematic diagram of a head wearing an air conduction receiver (candidate 1), a schematic diagram of a head wearing a bone conduction receiver (candidate 2), and a schematic diagram of a room with a speaker installed (candidate 3) as selection options. If candidate 1 is tapped, the system may be set to "air conduction measurement," if candidate 2 is tapped, it may be set to "bone conduction measurement," and if candidate 3 is tapped, it may be set to "sound field measurement." Furthermore, when setting the type of air conduction receiver or earphone to be used in air conduction measurement, the system may display multiple schematic diagrams as shown in Figure 5(A) as selection options, and the system may be set to the air conduction receiver or earphone corresponding to the tapped schematic diagram. In addition, when setting the measurement ear, the system may display a schematic diagram of the subject's head viewed from the front, and the ear tapped on the schematic diagram may be set as the measurement ear. Furthermore, when setting the ON / OFF of the boost function, the system may display a selection option as shown in Figure 9(A). By using such a configuration, the operation related to settings becomes intuitive and easy, thereby reducing the burden on the examiner.
[0106] In the above-described embodiment, when the usage image display unit 13 indicates the presentation of sound from the speaker, as shown in Figure 5(C), a diagram of three overlapping arc shapes is displayed for the measurement sound, and a diagram of three zigzag shapes is displayed for the noise. However, diagrams of different shapes may be displayed for other types of sound. Furthermore, the number of identical shapes may be increased or decreased depending on the magnitude of the sound presentation level (for example, one for the minimum and five for the maximum). Such a display allows the examiner to intuitively grasp the sound presentation level.
[0107] In the embodiment described above, responses from the subject are received using the response button 60. However, instead of the response button 60, another input device (for example, a tablet terminal with a response button displayed on the screen) may be connected to the audiometric device 1, and responses from the subject may be received through this device.
[0108] In the embodiment described above, the auditory measurement device 1 is implemented on dedicated hardware as shown in Figure 1(B). However, part or all of the auditory measurement device 1 may be implemented on a general-purpose computer (for example, a tablet device, notebook PC, desktop PC, etc.) equipped with a CPU, RAM, HDD, various I / Fs, a display, etc.
[0109] Furthermore, the configurations and numerical values mentioned in the explanation of the auditory measurement device 1 are merely examples, and it goes without saying that they can be modified as appropriate when implementing the present invention. [Explanation of symbols]
