Description

[Technical field]

[0001] The present invention relates to a program, a volume control method, and an information processing device. [Background technology]

[0002] There are hearing aids that support the hearing of users with hearing impairments by amplifying sounds that the user cannot hear. Tests for fitting (adjusting) hearing aids include a hearing test (pure tone hearing test) in which a certain tone such as a "beep" is played for each frequency and the lowest volume that can be heard for each frequency is recorded, and a speech intelligibility test in which speech sounds are played and the user is asked to write down the sounds that they hear.

[0003] The disadvantages of a fitting test include the need to visit a hearing aid store and the long hours of passive listening.

[0004] In view of this, for example, Patent Document 1 proposes a technology that enables hearing tests to be performed using a mobile phone and allows for easy settings of a hearing aid. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2010-200259 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, in the mobile terminal of Patent Document 1, a hearing test is performed by sequentially outputting test sounds in multiple frequency bands and multiple output levels. Therefore, the test takes time, and it is troublesome to perform a hearing test every time there is a sense of discomfort in hearing. In addition, the mobile terminal of Patent Document 1 does not perform a speech intelligibility test, but a speech intelligibility test is also necessary to improve the accuracy of fitting. However, if a speech intelligibility test is performed separately from a hearing test, fitting takes time and effort, which makes the user feel even more bothered.

[0007] An object of the present invention is to enable hearing aid fitting based on a hearing test and a speech intelligibility test to be performed quickly and easily. [Means for solving the problem]

[0008] In order to solve the above problems, the program of the present invention comprises: Computer, A plurality of slide bars to which different frequencies are assigned are displayed on the same screen of a display unit, Each of the plurality of slide bars is provided with a first slider for adjusting the volume of a test sound in a hearing test and a second slider for adjusting the volume of a test sound in a speech intelligibility test; When the first slider of any of the slide bars is operated, the volume of the test sound in the hearing test having the frequency assigned to the operated slide bar is adjusted according to the position of the first slider; When the second slider in any one of the slide bars is operated, the volume of the test sound in the speech intelligibility test at the frequency assigned to the operated slide bar is adjusted according to the position of the second slider; acquiring information on a volume adjustment result in the hearing test and information on a volume adjustment result in the speech intelligibility test; Function as a control unit. Effect of the Invention

[0009] According to the present invention, hearing aid fitting based on a hearing test and a speech intelligibility test can be performed quickly and simply. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, the embodiments of the present invention will be described with reference to the drawings. However, the embodiments described below are subject to various limitations that are technically preferable for implementing the present invention. Therefore, the technical scope of the present invention is not limited to the following embodiments and illustrated examples.

[0012] [Configuration of hearing aid fitting system 100] FIG. 1 is a diagram showing an example of the overall configuration of a hearing aid fitting system 100 according to the present invention. As shown in Fig. 1, the hearing aid fitting system 100 is configured to include a hearing aid 1 and a terminal device 2 (information processing device). The hearing aid 1 and the terminal device 2 are capable of transmitting and receiving data via wireless or wired communication. The terminal device 2 provides a user interface that enables the user to perform fitting of the hearing aid 1.

[0013] [Configuration of hearing aid 1] As shown in FIG. 1, the hearing aid 1 is configured with a control unit 11, an audio input unit 12, a sound processing unit 13, a pronunciation unit 14, a memory unit 15, a communication unit 16, etc., and each unit is connected via a bus 17.

[0014] The control unit 11 is a computer that controls each part of the hearing aid 1. Specifically, the control unit 11 is configured with at least one CPU (Central Processing Unit), RAM (Random Access Memory), etc. The control unit 11 reads out a specified program from among the programs stored in the storage unit 15, expands it in the RAM, and executes various processes in cooperation with the expanded program.

[0015] The audio input unit 12 is configured with a microphone. The audio input unit 12 takes in external audio, converts it into an electrical signal, and outputs it to the sound processing unit 13.

[0016] The sound processing unit 13 is equipped with an amplifier, etc., and processes the electrical signal of the voice input by the voice input unit 12 based on the fitting information 252 described later, such as amplifying it to suit the user's hearing characteristics, suppressing unnecessary noise, and emphasizing speech sounds, and outputs the processed signal to the pronunciation unit 14. Furthermore, the sound processor 13 generates a pure tone signal or a diagnostic sound signal of a specified volume and frequency based on the sound generation control information transmitted from the terminal device 2, and outputs the generated signal to the sound generator .

[0017] The sound generating unit 14 generates a sound based on the voice signal input from the sound processing unit 13.

[0018] The storage unit 15 is configured with a non-volatile semiconductor memory, etc. The storage unit 15 stores various programs and data required for executing the programs. For example, the storage unit 15 stores fitting information 252 received from the terminal device 2.

[0019] The communication unit 16 performs communication control for transmitting and receiving data via wireless or wired communication with an external device such as the terminal device 2. In this embodiment, communication between the hearing aid 1 and the terminal device 2 is performed by BLE (Bluetooth Low Energy) or the like, but the communication method is not particularly limited.

[0020] [Configuration of terminal device 2] The terminal device 2 is, for example, a smartphone, a tablet terminal, or the like. As shown in FIG. 1, the terminal device 2 includes a control unit 21, an operation unit 22, a display unit 23, a communication unit 24, a storage unit 25, etc., and each unit is connected via a bus .

[0021] The control unit 21 is a computer that controls each part of the terminal device 2. Specifically, the control unit 21 is configured to include at least one CPU (Central Processing Unit), RAM (Random Access Memory), etc. The control unit 21 reads out a specified program from among the programs stored in the storage unit 25, expands the program in the RAM, and executes various processes including a hearing aid fitting process described below in cooperation with the expanded program.

[0022] The operation unit 22 is composed of push button switches, a touch panel attached to the display unit 23, etc. The operation unit 22 outputs to the control unit 21 an operation signal of the push button switch by the user or an operation signal on the screen of the display unit 23 by a finger or the like.

[0023] The display unit 23 is configured with a display device such as a liquid crystal display, an organic EL (Electro Luminescence) display, or the like, and performs display based on the control operation of the control unit 21.

[0024] The communication unit 24 performs communication control for transmitting and receiving data to and from external devices such as the hearing aid 1.

[0025] The storage unit 25 is configured with a non-volatile semiconductor memory, a HDD (Hard Disk Drive), etc. The storage unit 25 stores various programs and data required for executing the programs. The storage unit 25 is not limited to being built into the terminal device 2, and may include an external recording medium that is detachable from the terminal device 2.

[0026] For example, the storage unit 25 stores a hearing aid fitting application 251. The hearing aid fitting application 251 is an application program for fitting the hearing aid 1. The hearing aid fitting application 251 includes a program for executing a hearing aid fitting process, which will be described later. The storage unit 25 also stores fitting information 252 acquired through the hearing aid fitting process.

[0027] [Operation of the hearing aid fitting system 100] Next, the operation of the hearing aid fitting system 100 will be described.

[0028] First, while wearing the hearing aid 1 on the ear, the user operates the operation unit 22 of the terminal device 2 to instruct the hearing aid fitting application 251 to be launched. When an instruction to launch the hearing aid fitting application 251 is given by operating the operation unit 22 in the terminal device 2, the control unit 21 launches the hearing aid fitting application 251. The control unit 21 then establishes a communication connection with the hearing aid 1 via the communication unit 24, and executes the hearing aid fitting process in cooperation with the hearing aid fitting application 251.

[0029] 2 is a flow chart showing the flow of the hearing aid fitting process, which will be described below with reference to FIG.

[0030] First, the control unit 21 causes the display unit 23 to display the fitting screen 30 (step S1).

[0031] 3 is a diagram showing an example of a fitting screen 30. The fitting screen 30 is a user interface for performing a hearing test and a speech intelligibility test for fitting the hearing aid 1. Here, the hearing test described in this application refers to a so-called pure tone hearing test, and does not include a speech intelligibility test. Also, a speech intelligibility test is generally performed by having a user listen to speech sounds and writing (selecting) the speech sounds that are heard, thereby obtaining a correct answer rate, but in this embodiment, the speech intelligibility test is performed by having a user listen to speech sounds (called diagnostic sounds), and obtaining the volume at which the diagnostic sounds can be recognized (heard).

[0032] As shown in FIG. 3, the fitting screen 30 is provided with a diagnostic voice text box 31 and a random button 32. The diagnostic voice text box 31 is an input field for the user to arbitrarily input text (character string) of a diagnostic voice to be pronounced as a test sound in a speech intelligibility test. The random button 32 is a button for instructing the control unit 21 to randomly input the text of a diagnostic voice to be pronounced as a test sound in a speech intelligibility test.

[0033] In addition, a plurality of slide bars 33 for adjusting the volume are displayed side by side on the fitting screen 30. A different frequency (Hz) is assigned to each of the plurality of slide bars 33. In the fitting screen 30 shown in FIG. 3, a low frequency is assigned to the left slide bar 33, and a higher frequency is assigned as the position of the slide bar 33 moves from left to right. For example, 125 Hz, 250 Hz, 500 Hz, 1000 Hz, 2000 Hz, 4000 Hz, and 8000 Hz are assigned in order from the left slide bar 33. The vertical position of each slide bar 33 corresponds to the volume (dB). For example, the lowest position of each slide bar 33 corresponds to -20 dB, and the highest position corresponds to 120 dB. Note that the frequency and the vertical volume range assigned to each slide bar 33 may be changed depending on the performance of the hearing aid 1, and are not limited to the above. In addition, in FIG. 3, the information about the frequency of each slide bar 33 is only displayed as "low⇔high", but it is also possible to display the frequency value or an image (e.g., a musical note) representing the pitch corresponding to the frequency (see FIG. 5).

[0034] Each slide bar 33 displays a first slider 33a for adjusting the volume of a test sound (pure tone) in a hearing test, and a second slider 33b for adjusting the volume of a test sound (diagnostic sound) in a speech intelligibility test. In this application, the slide bar 33 refers to the entirety including the first slider 33a, the second slider 33b, and the bar-shaped area in which these can be moved. The sliders such as the first slider 33a and the second slider 33b refer to marks indicating the current position. The sliders may also be called knobs, handles, thumbs, icons, etc.

[0035] When the user holds the first slider 33a of any of the slide bars 33, a pure tone of a frequency assigned to the slide bar 33 on which the first slider 33a is being held is generated at a volume corresponding to the position of the first slider 33a. When the first slider 33a is slid, the volume of the generated pure tone is changed according to the change in the position of the first slider 33a. That is, by sliding the first slider 33a, the volume of the generated pure tone can be adjusted. The user slides the first slider 33a to adjust the generated sound to the minimum volume that the user can hear. When the adjustment is completed and the finger is released from the first slider 33a, the generation of the pure tone is stopped, and information on the volume (information on the volume adjustment result) corresponding to the position of the first slider 33a is acquired. This makes it possible to obtain a value indicating the user's hearing ability for the sound of the frequency assigned to the operated slide bar 33.

[0036] When the user holds the second slider 33b of any of the slide bars 33, a diagnostic sound of a frequency assigned to the slide bar 33 on which the second slider 33b is held is generated at a volume corresponding to the position of the second slider 33b. When the second slider 33b is slid, the volume of the generated diagnostic sound is changed according to the change in the position of the second slider 33b. That is, the volume of the generated diagnostic sound can be adjusted by sliding the second slider 33b. The user slides the second slider 33b to adjust the generated diagnostic sound to the minimum volume that the user can recognize (hear). When the adjustment is completed and the finger is released from the second slider 33b, the generation of the diagnostic sound is stopped, and information on the volume (information on the volume adjustment result) corresponding to the position of the second slider 33b is acquired. This makes it possible to obtain a value indicating the user's speech clarity for the sound of the frequency assigned to the operated slide bar 33.

[0037] Here, the first slider 33a is for adjusting the volume so that the pure sound becomes the minimum volume at which the user can hear it, and the second slider 33b is for adjusting the volume so that the diagnostic sound becomes the minimum volume at which the user can recognize (hear). Therefore, in each slide bar 33, the first slider 33a is always located below the second slider 33b (lower volume side) and does not overlap with the second slider 33b or is located above the second slider 33b (higher volume side). Due to such a relationship between the hearing test and the speech intelligibility test, it is possible to provide two sliders on each slide bar 33 on the fitting screen 30. In this embodiment, when the first slider 33a hits the second slider 33b by sliding it upward, the second slider 33b slides upward in response to the upward sliding of the first slider 33a. When the second slider 33b hits the first slider 33a by sliding it downward, the first slider 33a does not move.

[0038] When the fitting information 252 is not stored in the storage unit 25, the control unit 21 sets the positions of the first slider 33a and the second slider 33b to predetermined positions in each slide bar 33 when displaying the fitting screen 30. When the fitting information 252 is stored in the storage unit 25, the control unit 21 sets the positions of the first slider 33a and the second slider 33b in each slide bar 33 based on the fitting information 252. In addition, the control unit 21 displays the diagnostic voice text used at the most recent fitting in the diagnostic voice text box 31. The fitting information 252 in this embodiment is information on the volume adjustment results in the hearing test and the speech intelligibility test, and is information indicating the volume for each frequency adjusted in each test. That is, if the hearing aid 1 has been fitted in the past, the first slider 33a and the second slider 33b are displayed in the slide bars 33 of the fitting screen 30 at positions corresponding to the volume adjusted in the most recent fitting. Therefore, in the first fitting, fitting (adjustment) is required for each frequency, but once fitting is performed, it is possible to complete the fitting by making fine adjustments only for frequencies of interest.

[0039] Returning to FIG. 2, the control unit 11 determines whether or not the diagnostic voice text box 31 has been tapped (step S2). When it is determined that the diagnostic voice text box 31 has been tapped (step S2; YES), the control unit 21 accepts a text input from the diagnostic voice text box 31 (step S3), and proceeds to step S6.

[0040] When it is determined that the diagnostic voice text box 31 has not been tapped (step S2; NO), the control unit 21 determines whether or not the random button 32 has been tapped (step S4). When it is determined that the random button 32 has been tapped (step S4; YES), the control unit 21 automatically inputs random text into the diagnostic voice text box 31 (step S5), and proceeds to step S6. When it is determined that the random button 32 has not been tapped (step S4; NO), the control unit 21 proceeds to step S6.

[0041] In step S6, the control unit 21 determines whether or not any of the sliders of the slide bar 33 (the first slider 33a or the second slider 33b) is held (step S6). When it is determined that the slider of any of the slide bars 33 is not being held (step S6; NO), the control unit 21 proceeds to step S8.

[0042] On the other hand, if it is determined that any of the sliders is held (step S6; YES), the control unit 21 executes a volume adjustment process (step S7).

[0043] 4 is a flowchart showing the flow of the volume adjustment process executed in step S7. The volume adjustment process will be described below with reference to FIG.

[0044] First, the control unit 21 acquires the text input in the diagnostic voice text box 31 (step S701).

[0045] Next, the control unit 21 determines whether the diagnostic voice text box 31 is blank or not based on whether the text inputted in the diagnostic voice text box 31 has been acquired (step S702). When it is determined that the diagnostic voice text box 31 is blank (step S702; YES), the control unit 21 acquires a default text as a diagnostic voice text (step S703) and proceeds to step S704. The default text is stored in the storage unit 25 in advance. When it is determined that the diagnostic voice text box 31 is not blank (step S702; NO), the control unit 21 proceeds to step S704.

[0046] In step S704, the control unit 21 acquires the frequency assigned to the slide bar 33 where the slider (the first slider 33a or the second slider 33b) is being held (step S704).

[0047] Next, the control unit 21 determines whether the held slider is the first slider 33a (step S705). If it is determined that the held slider is the first slider 33a (step S705; YES), the control unit 21 causes the hearing aid 1 to play a pure tone of a frequency corresponding to the position of the held first slider 33a (i.e., a pure tone of a frequency assigned to the held slide bar 33) at a volume corresponding to the position of the held first slider 33a for a predetermined period of time (step S706), and then proceeds to step S709. For example, the control unit 21 transmits sound generation control information indicating the type of sound (pure tone), frequency, and volume to be generated by the hearing aid 1 to the hearing aid 1 via the communication unit 24. When the control unit 11 of the hearing aid 1 receives sound generation control information from the terminal device 2 via the communication unit 16, the control unit 11 generates a pure tone signal of a specified frequency and volume using the sound processing unit 13 based on the received sound generation control information, and generates the pure tone signal using the sound generation unit 14.

[0048] On the other hand, when it is determined that the held slider is not the first slider 33a (step S705; NO), the control unit 21 determines whether or not the held slider is the second slider 33b (step S707). If it is determined that the held slider is the second slider 33b (step S707; YES), the control unit 21 causes the hearing aid 1 to produce a diagnostic sound of a frequency corresponding to the position of the held second slider 33b (i.e., a diagnostic sound based on the diagnostic sound text of the frequency assigned to the held slide bar 33) at a volume corresponding to the position of the held second slider 33b (step S708), and proceeds to step S709. For example, the control unit 21 transmits pronunciation control information indicating the diagnostic voice text, frequency, and volume to be pronounced by the hearing aid 1 to the hearing aid 1 via the communication unit 24. When the control unit 11 of the hearing aid 1 receives the pronunciation control information from the terminal device 2 via the communication unit 16, it causes the sound processing unit 13 to generate an audio signal of a diagnostic voice with a specified frequency and volume based on the received pronunciation control information, and causes the pronunciation unit 14 to pronounce it.

[0049] When it is determined that the held slider is neither the first slider 33a nor the second slider 33b (step S707; NO), the control unit 21 proceeds to step S709.

[0050] In step S709, the control unit 21 determines whether or not it has been detected that the finger has been released from the slider (step S709). When it is determined that the release of the finger from the slider has not been detected (step S709; NO), the control unit 21 returns to step S705. When it is determined that the finger has been removed from the slider (step S710; YES), the control unit 21 proceeds to step S8 in FIG.

[0051] In step S8 of FIG. 2, the control unit 21 determines whether or not an instruction to end the fitting has been given (step S8). For example, when the control unit 21 detects that the end button 34 is pressed, it determines that the fitting is finished.

[0052] When it is determined that the end of fitting has not been instructed (step S8; NO), the control unit 21 returns to step S2. If it is determined that an instruction to end fitting has been given (step S8; YES), the control unit 21 stores the fitting information 252 in the memory unit 25 and transmits it to the hearing aid 1 via the communication unit 24 (step S9), and ends the hearing aid fitting process. The fitting information 252 is, for example, information on the volume adjustment results in a hearing test for each frequency (the volume value corresponding to the current position of each first slider 33a) and information on the volume adjustment results in a speech intelligibility test for each frequency (the volume value corresponding to the current position of each second slider 33b and the diagnostic voice text used in the test).

[0053] In the hearing aid 1, when the fitting information 252 is received from the terminal device 2 by the communication unit 16, the control unit 11 replaces the fitting information 252 stored in the storage unit 15 with the received fitting information 252. In the hearing aid 1, when external sound is acquired by the audio input unit 12 and the electrical signal is input, the control unit 11 causes the sound processing unit 13 to process the input electrical signal based on the fitting information 252, such as amplifying the input electrical signal to suit the user's hearing characteristics, suppressing unnecessary noise, and emphasizing speech, and then causes the processed sound to be pronounced by the pronunciation unit 14.

[0054] In the above embodiment, the hearing aid 1 was fitted without distinguishing between the left and right ears, but as shown in Fig. 5, a switch button 35 for switching between the left and right ears may be provided on the fitting screen 30. The control unit 21 may then fit the hearing aid 1 to the left or right ear in response to a switching operation using the switch button 35. The hearing aid fitting process performed for each ear is the same as that described in the above embodiment, except that when the hearing aid 1 produces a test sound, the sound is produced by the sound production unit 14 on the ear side to be fitted, and the fitting information 252 is stored in the memory unit 25 separately for left and right.

[0055] As described above, the control unit 21 of the terminal device 2 causes the display unit 23 to display the fitting screen 30 on which the multiple slide bars 33 to which different frequencies are assigned are displayed. Each of the multiple slide bars 33 is provided with a first slider 33a and a second slider 33b. When the first slider 33a of any of the slide bars 33 is slid, the control unit 21 adjusts the volume of the test sound in the hearing test of the frequency assigned to the operated slide bar 33 according to the position of the first slider 33a, and when the second slider 33b of any of the slide bars 33 is operated, the control unit 21 adjusts the volume of the test sound in the speech intelligibility test of the frequency assigned to the operated slide bar 33 according to the position of the second slider 33b. Then, the control unit 21 acquires information on the volume adjustment result in the hearing test and information on the volume adjustment result in the speech intelligibility test.

[0056] Therefore, hearing tests and speech intelligibility tests can be performed simultaneously on a single fitting screen 30, allowing fitting of the hearing aid 1 to be completed quickly and easily, thereby reducing the hassle of fitting conventional hearing aids.

[0057] On the fitting screen 30, the first slider 33a is located on the lower volume side than the second slider 33b on the slide bar 33. Therefore, by operating the first slider 33a and the second slider 33b on one slide bar 33, it becomes possible to adjust the volume of the test sound in the hearing test and the volume of the test sound in the speech intelligibility test.

[0058] Furthermore, the control unit 21 causes the hearing aid 1 to emit a test sound at a volume corresponding to the operated first slider 33a or second slider 33b only while the first slider 33a or second slider 33b is being operated. Therefore, since the test sound is emitted only while the user is operating the slider, there is no need for the user to passively listen to the test sound for a long period of time as in the past, and fitting can be performed comfortably.

[0059] Furthermore, the control unit 21 displays a diagnostic voice text box 31 on the fitting screen 30 for the user to arbitrarily input text of a voice to be pronounced as a test sound in a speech intelligibility test, and while the second slider 33b is being operated, pronounces the voice of the text input from the diagnostic voice text box 31 as a test sound in the speech intelligibility test. Therefore, fitting can be performed using speech sounds that are difficult for the user to hear, and therefore fitting can be performed with high accuracy according to the user's hearing characteristics.

[0060] In addition, when speech sounds that are difficult to hear differ depending on the frequency, for example, when "ka-ki-ku" is difficult to hear in a high pitch but "ai-u" is difficult to hear in a low pitch, the speech sounds that are difficult to hear may be input in a line in the diagnostic voice text box 31, and the voice input from the diagnostic voice text box 31 may be connected and pronounced as the test sound in the speech intelligibility test. Then, the user may slide the second slider 33b to the volume position where the entire diagnostic voice can be recognized. This allows for easy fitting even when speech sounds that are difficult to hear differ depending on the frequency.

[0061] In addition, the control unit 21 stores information on the volume adjustment results in the hearing test and information on the volume adjustment results in the speech intelligibility test in the memory unit 25, and when newly displaying multiple slide bars on the fitting screen 30, sets the positions of the first slider 33a and the second slider 33b on each of the multiple slide bars 33 based on the information on the volume adjustment results stored in the memory unit 25. Therefore, once fitting is performed, it is possible to complete the fitting by making fine adjustments only for frequencies of interest. Therefore, fitting can be performed easily in a short time.

[0062] Furthermore, as shown in FIG. 2, the fitting screen 30 after adjustment displays the volume adjustment results in the hearing test and the speech intelligibility test for each frequency in a graph depending on the positions of the first slider 33a and the second slider 33b, so that the user can easily grasp the volume adjustment results in the hearing test and the speech intelligibility test for each frequency. Fig. 5 is a diagram showing an example of the fitting screen 30 after adjustment when the diagnostic voice is "Okihamu". Fig. 6 is a diagram showing an example of the fitting screen 30 after adjustment when the diagnostic voice is "Sashisuse". According to the fitting screen 30 in Fig. 5, it can be seen that there is variation in the audibility of "Okihamu" depending on the frequency. According to the fitting screen 30 in Fig. 6, it can be seen that "Sashisuse" becomes more difficult to recognize as the frequency increases.

[0063] The contents described in the above embodiment are just preferred examples of the program, the volume control method, and the information processing device according to the present invention, and the present invention is not limited to these.

[0064] For example, in the above embodiment, an example was described in which the present invention is applied to fitting a hearing aid, but the present invention is not limited to hearing aids and can be applied to fitting ear devices including sound collectors, sound processing devices, and earphones.

[0065] In the above embodiment, the diagnostic voice text can be arbitrarily input, and the diagnostic voice can be freely changed, but the diagnostic voice may be fixed.

[0066] In the above embodiment, the slide bar 33 is disposed vertically, but it may be disposed horizontally. In this case, the left side of the slide bar 33 is the low volume side, and the right side is the high volume side.

[0067] In the above embodiment, the test sound for the hearing test is a pure tone, but the test sound for the hearing test may be a speech sound (diagnostic sound) similar to that for the speech intelligibility test.

[0068] Furthermore, in the above embodiment, the hearing aid 1 is described as being fitted by adjusting the volume in the hearing test and the speech intelligibility test using the fitting screen 30 to which the present invention is applied, but the volume adjustment in the hearing test and the speech intelligibility test using the fitting screen 30 to which the present invention is applied is not limited to being aimed at fitting the hearing aid 1. Furthermore, the terminal device 2 may include a sound processing unit and a sound generation unit, and the terminal device 2 may generate test sounds in the hearing test and the speech intelligibility test.

[0069] In the above embodiment, a semiconductor memory such as a ROM or a hard disk is used as a computer-readable medium for the program according to the present invention, but the present invention is not limited to this example. As other computer-readable media, a portable recording medium such as a CD-ROM can be applied. Furthermore, a carrier wave can be applied as a medium for providing data of the program according to the present invention via a communication line.

[0070] In addition, in the above embodiment, it has been described that the user operates the first slider 33a and the second slider 33b by sliding these sliders on the screen with his / her finger, but the first slider 33a and the second slider 33b may be operated by a method other than sliding with a finger. For example, when the user touches a button (or the first slider 33a to be operated) for starting a hearing test associated with each slide bar 33, the control unit 21 automatically moves the first slider 33a up little by little. The user stops the movement of the first slider 33a when he hears a sound. The operation of stopping the movement of the first slider 33a may be by voice or touch. Similarly, for example, when the user touches a button (or the second slider 33b to be operated) for starting a speech intelligibility test associated with each slide bar 33, the control unit 21 automatically moves the second slider 33b up little by little. The user stops the movement of the second slider 33b when he recognizes the speech sound. The operation of stopping the movement of the second slider 33b may be by voice or touch. In this way, the case where the slider is operated by an operation other than a slide operation, such as touch or voice, is also included in the "slider is operated" of the claims of this application.

[0071] In addition, the detailed configuration and operation of the hearing aid 1 and the terminal device 2 may be modified as appropriate without departing from the spirit of the invention.

[0072] Although the embodiment of the present invention has been described above, the technical scope of the present invention is not limited to the above embodiment, but is defined based on the claims. Furthermore, the technical scope of the present invention also includes equivalent ranges that are made by adding modifications that are not related to the essence of the present invention from the claims.
