Description

Technical Field

[0001] The invention relates to a method, a computer program and a computer-readable medium for controlling the volume dynamics of a hearing device. Furthermore, the invention relates to a hearing system with a hearing device. Background Art

[0002] Hearing devices are typically small and complex devices. Hearing devices may include a processor, microphone, speaker, memory, housing, and other electronic and mechanical components. Some example hearing devices are behind-the-ear (BTE) devices, receiver-in-the-canal (RIC) devices, in-the-ear (ITE) devices, completely in-the-canal (CIC) devices, and invisible-in-the-canal (IIC) devices. Users may prefer one of these hearing devices over another based on hearing loss, aesthetic preferences, lifestyle needs, and budget.

[0003] Hearing devices often have functions (or so-called modifiers) for manually adjusting the sound output of the hearing device. For example, the overall volume, treble and bass can be adjusted by standard modifiers. A special type of modifier is a dynamic volume modifier that only amplifies a certain volume range. For example, a soft sound modifier can amplify soft sounds and / or can attenuate loud sounds. Vice versa, a loud sound modifier can amplify loud sounds and / or can attenuate soft sounds.

[0004] Users of hearing devices more often report that soft sounds are too soft, but less often report that soft sounds are too loud. Conversely, users more often report that loud sounds are too loud, but less often report that loud sounds are too soft. Summary of the invention

[0005] It is an object of the present invention to simplify volume control of a hearing instrument.

[0006] This object is achieved by the subject-matter of the independent claims. Further exemplary embodiments are evident from the dependent claims and the following description.

[0007] A first aspect of the invention relates to a method for controlling volume dynamics of a hearing device. The hearing device may be a device as described above. The hearing device may be a hearing aid adapted to compensate for a hearing loss of a user.

[0008] The hearing device may include a microphone, a sound processor, and a sound output device, such as a speaker. The sound processor may receive a sound signal from the microphone and may frequency-dependently amplify and / or attenuate the sound signal. The sound signal may then be output to the user's ear by a sound output device such as a speaker.

[0009] The term "volume dynamics" may refer to volume-dependent volume amplification. In other words, a sound of a certain volume may be amplified by a certain volume-dependent factor and / or may be amplified to another volume. For example, a soft sound may be amplified differently than a loud sound. Typically, the volume of a sound signal may be indicated in dB (decibels).

[0010] The methods described herein may be performed automatically by a hearing device and optionally by a mobile device in data communication with the hearing device.

[0011] According to an embodiment of the invention, a method comprises: receiving a volume modifier value, the volume modifier value being selected from a volume modifier range of volume modifier values ​​between a first value and a second value, the volume modifier range being divided into a soft sound emphasizer range between the first value and a neutral value and a loud sound limiter range between the neutral value and the second value. Typically, the volume modifier value may be selected by a user of the hearing device. For example, the hearing device and / or a mobile device in data communication with the user provides a user interface for selecting the volume modifier value.

[0012] The volume modifier value may be selected from a range of integers. For example, the first value may be a negative value, the neutral value may be 0, and the second value may be a positive value. As a specific example, the volume modifier value may be an integer from -5 to 5 and / or the volume modifier range may be a range from -5 to 5. The soft sound emphasizer range may include negative numbers and / or integers. The loud sound limiter range may include positive numbers and / or integers.

[0013] Typically, in the soft sound emphasizer range, soft sounds should be amplified, and in the loud sound limiter range, loud sounds should be attenuated. In this way, these two different tasks can be achieved by selecting only one volume modifier value.

[0014] According to an embodiment of the present invention, the method also includes: when the volume modifier value is within the soft sound emphasizer range, modifying the volume control curve by increasing the value of the volume control curve within the range below the reference value, wherein the volume control curve defines the amplitude of amplifying a sound signal with a specific (input) volume to a desired (output) volume.

[0015] The volume control curve may define a function that maps a specific (input) volume to another (output) volume. In other words, using the volume control curve, a specific amplification of the volume of the sound signal may be defined. The volume control curve may be defined by a set of points, and other values ​​of the volume control curve may be determined by interpolation between these points. For example, support points for the volume control curve may be defined at quiet sound values, soft sound values, medium sound values, and loud sound values ​​of the input volume.

[0016] When the volume modifier value is within the soft sound emphasizer range (i.e., the user wishes to amplify soft sounds and optionally attenuate loud sounds), one or more values ​​below the reference value are increased. The reference value may be a medium sound value that separates soft sounds from loud sounds. For example, the reference value may be between 40 dB and 50 dB.

[0017] According to an embodiment of the present invention, the method further comprises: when the volume modifier value is within the loud sound limiter range, modifying the volume control curve by increasing the value of the volume control curve within the range above the reference value. When the volume modifier value is within the loud sound limiter range (i.e., the user wishes to attenuate loud sounds), reducing one or more values ​​above the reference value. The reference value may be a medium sound value that may separate soft sounds from loud sounds. For example, the reference value may be between 40 dB and 50 dB.

[0018] According to one embodiment of the invention, the method further comprises: applying the modified volume control curve to a sound processor of the hearing device, so that the sound signal processed by the hearing device and output by the hearing device to the user is amplified according to the modified volume control curve. The sound processor may additionally amplify the sound signal defined by the volume control curve, which sound processor may also additionally frequency-dependently amplify the sound signal, which sound signal may have been acquired using a microphone of the hearing device, for example. This may mean that it is determined how loud the sound signal is, and depending on this value, the volume of the sound signal is set to a volume value as defined by the volume control curve.

[0019] According to an embodiment of the present invention, when the volume modifier value is within the soft sound emphasizer range, the value of the volume control curve within the range above the reference value is reduced. When the soft sound should be amplified, not only the soft sound may be amplified, but also the load sound may be attenuated.

[0020] According to an embodiment of the present invention, when the volume modifier value is within the loud sound limiter range, the value of the volume control curve within the range below the reference value is not modified. On the other hand, when the loud sound should be amplified, the amplification of the soft sound can remain unchanged, because the soft sound is always softer than the loud sound.

[0021] According to an embodiment of the present invention, values ​​within a range below a reference value are increased by adding an offset value multiplied by the absolute value of the volume modifier value. Values ​​within a range above a reference value may also be increased by adding an offset value multiplied by the absolute value of the volume modifier value. Typically, the volume modifier value may be used as a factor multiplied by the offset value. This may apply to situations where the volume modifier value is positive and / or negative. It must be noted that the differences between adjacent modifier values ​​may be the same.

[0022] According to an embodiment of the invention, all values ​​of the volume control curve are increased by an equal offset below a reference value.Amplification of soft sounds may be performed by moving the volume control curve to higher values ​​with a constant offset, which may depend on the volume modifier value.

[0023] According to an embodiment of the present invention, the volume control curve includes a stable range of equal values ​​between the soft sound value and the medium sound value, and the reference value is greater than or equal to the medium sound value. The stable range can be a range of volume in which the soft sound is amplified by a maximum factor.

[0024] According to an embodiment of the present invention, when the volume modifier value is within the soft sound emphasizer range, the value of the stable range is increased equally. In other words, a constant offset may be added to all values ​​within the stable range.

[0025] Typically, a volume control curve may be defined by a linear portion defined by its endpoints. Between these endpoints or support points, the volume control curve may be linearly interpolated.

[0026] According to an embodiment of the present invention, the volume control curve includes a first linear range between a quiet sound value and a soft sound value. When the value of the stationary range increases by an offset, the value of the volume control curve in the first linear range can increase by the same offset. Another possibility is to shift the value at the soft sound value by the offset and keep the value at the quiet sound value.

[0027] According to an embodiment of the present invention, the volume control curve includes a second linear range between a medium sound value and a loud sound value. When the value of the stable range increases, the slope of the second linear range can be reduced so that the volume control curve remains connected in the stable range and the second linear range.

[0028] Usually, the volume control curve can be modified only so that it remains continuous. This can be achieved by moving the endpoints of the linear portion (eg, the first linear range, the stationary range, and the second linear range).

[0029] According to an embodiment of the invention, when the volume modifier value is within the loud sound limiter range, the values ​​of the volume control curve within the plateau range and the first linear range are not modified.As already mentioned, when loud sounds are amplified, soft sounds do not necessarily need to be attenuated.

[0030] According to an embodiment of the invention, when the volume modifier value is within the loud sound limiter range, the slope of the volume control curve within the second linear range above the plateau range is reduced. The reduction in slope may be proportional to the volume modifier value.

[0031] According to an embodiment of the present invention, an unmodified volume control curve is stored in a memory of the hearing device. For example, the unmodified volume control curve has been fitted to the hearing loss of a user of the hearing device. When the hearing device is adapted to the needs of the user (e.g., during fitting), the unmodified volume control curve (i.e., the volume control curve used as a basis for dynamic volume adaptation as described herein) is preset in the hearing device.

[0032] According to an embodiment of the present invention, the method further comprises: providing a user interface to a mobile device of the user, wherein the user interface comprises a volume modifier control element that can be changed by the user to select a volume modifier value. The mobile device (e.g., a smart phone or a tablet computer) carried by the user can communicate data with the hearing device. The mobile device can provide a computer program for adjusting a parameter in the hearing device. The computer program can include a graphical user interface having a control element (e.g., a slider) for setting the volume modifier.

[0033] When the user has selected a volume modifier value, the selected volume modifier value may be sent from the mobile device to the hearing device.All other method steps described above with respect to receiving a volume modifier value, adjusting a volume control curve etc. may be performed by the hearing device.

[0034] Further aspects of the invention relate to a computer program for controlling volume dynamics of a hearing device, which computer program, when executed by a processor, is adapted to perform the steps of the method as described above and in the following and to a computer readable medium in which such a computer program is stored.

[0035] For example, the computer program may be executed in a processor of a hearing device, which may be carried behind the ear by a person, for example. The computer readable medium may be a memory of the hearing device. The computer program may also be at least partially executed by a processor of a mobile device, and the computer readable medium may be a memory of the mobile device. Steps of the method may be performed by the hearing device, and other steps of the method may be performed by the mobile device.

[0036] Typically, a computer readable medium may be a floppy disk, a hard disk, a USB (Universal Serial Bus) storage device, a RAM (Random Access Memory), a ROM (Read Only Memory), an EPROM (Erasable Programmable Read Only Memory), or a flash memory. The computer readable medium may also be a data communication network that allows downloading program code, such as the Internet. The computer readable medium may be a non-transitory medium or a transient medium.

[0037] Another aspect of the invention relates to a hearing system adapted to perform the method as described above and in the following, the hearing system comprising a hearing device and optionally a mobile device providing a user interface for selecting a volume modifier value. The hearing device and / or the mobile device may comprise a processor and a memory in which a computer program is stored. The hearing device may comprise a microphone for acquiring a sound signal, the volume of which is subjected to a volume-dependent adjustment using the method.

[0038] It has to be understood that features of the method as described above and below may be features of the computer program, the computer readable medium and the hearing system as described above and below, and vice versa.

[0039] These and other aspects of the invention will be apparent from and elucidated with reference to the embodiments described hereinafter. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Figure 1 Schematically shown is a hearing system 10 with a hearing device 12 in the form of a behind-the-ear device and a mobile device 14. It has to be noted that the hearing device 12 is a specific embodiment and the methods described herein may also be performed by other types of hearing devices, such as in-the-ear devices.

[0048] The hearing device 12 includes a portion 15 at the back of the ear and a portion 16 to be placed in the ear canal of the user. The portions 15 and 16 are connected by a tube 18. In the portion 15, a microphone 20, a sound processor 22, and a sound output device 24 (e.g., a speaker) are provided. The microphone 20 can acquire the ambient sound of the user and can generate a sound signal, the sound processor 22 can amplify the sound signal, and the sound output device 24 can generate a sound guided through the tube 18 and the in-ear portion 16 into each ear canal of the user.

[0049] The hearing device 12 may include a processor 26 adapted to adjust parameters of the sound processor 22 such that the output volume of the sound signal is adjusted based on the input volume. These parameters may be determined by a computer program running on the processor 26. For example, using a knob 28 of the hearing device 12, a user may select modifiers (e.g., bass, treble, noise suppression, dynamic volume, etc.) and may select levels and / or values ​​of these modifiers that change the frequency-dependent gain and dynamic volume of the sound processor 22. All of these functions may be implemented as a computer program stored in a memory 30 of the hearing device 12, wherein the computer program may be executed by the processor 26.

[0050] The hearing device 12 may include a transmitter / receiver 32 for (e.g., wireless) data communication with a transmitter / receiver 34 of a mobile device 14, which may be a smartphone or tablet computer. The modifiers mentioned above and their levels and / or values ​​may also be adjusted using the mobile device. This may be performed using a computer program running in a processor 36 of the mobile device 14 and stored in a memory 38 of the mobile device 14. The computer program may provide a graphical user interface 40 on a display 42 of the mobile device 14.

[0051] In case of adjusting the dynamic volume, the graphical user interface 40 may comprise a slider 44 for selecting a volume modifier value 46, which is indicated by a line next to the slider 44. The selected volume modifier value 46 may be sent to the hearing device 12. Alternatively or additionally, the user may select the volume modifier value 46 using the hearing device 12 itself (e.g. via the knob 28).

[0052] The hearing device 12 determines and / or adjusts a volume control curve as described above and below based on the volume modifier value 46 and changes parameters of the sound processor 22 accordingly.

[0053] Figure 2An embodiment of how a volume modifier value 46 can be implemented is shown. The volume modifier value 46 can be selected from a volume modifier range 48 of volume modifier values ​​between a first value 50 and a second value 52. The volume modifier range 48 can be divided into a soft sound emphasizer range 54 between the first value 50 and a neutral value 51 and a loud sound limiter range 56 between the neutral value 51 and the second value 52. As shown, the volume modifier value 46 can be selected from a discrete set of values, or alternatively can be a continuous value. The first value 50 can be the lowest value and the second value can be the highest value. The neutral value 51 can be 0 and / or can be in the middle of the first value 50 and the second value 52.

[0054] Figure 3 and Figure 4 A diagram with volume control curves 58 indexed by corresponding volume modifier values ​​46 is shown.

[0055] exist Figure 3 and Figure 4 In the figure, the input level of the sound signal in dB SPL (decibel sound pressure level) is depicted from left to right, and the desired output level of the processed sound signal in dB SPL is shown from bottom to top.

[0056] The volume control curve 58 is defined by four points at a quiet sound value 60a, a soft sound value 60b, a medium sound value 60c, and a loud sound value 60d of the input level of the sound signal. The volume control curve 58 includes: a first linear range 62a having a positive slope between the quiet sound value 60a and the soft sound value 60b; a flat range 62b having an equal value between the soft sound value 60b and the medium sound value 60c; and a second linear range 62c having a negative slope between the medium sound value 60c and the loud sound value 60d. Other values ​​of the volume control curve 58 can be determined by linearly interpolating between these points.

[0057] The curve 580 is an unmodified volume control curve that may be implemented in the hearing device 12 during a fitting process when the hearing device 12 is adapted to the user's hearing loss. When the neutral value 51 for the volume modifier value is selected, the unmodified, fitted volume control curve 580 may be saved in the memory 30 and / or parameters of the sound processor 22 may be set according to the curve 580.

[0058] exist Figure 3 Middle, curve 58 -4 , 58 -3 , 58 -2 , 58 -1is a curve that has been determined for volume modifier values ​​-4, -3, -2, -1 (i.e., volume modifier values ​​46 in the soft sound emphasizer range 54) according to the unmodified curve 580. In this case, a value in the range below the reference value 64 (which may be, for example, the medium sound value 60c) is added.

[0059] exist Figure 4 , curves 584, 583, 582, 581 are curves that have been determined for volume modifier values ​​4, 3, 2, 1 (i.e., volume modifier value 46 within loud sound limiter range 56) based on unmodified curve 580. In this case, the values ​​within the range above reference value 64 are reduced.

[0060] Figure 5 A flow chart of a method for controlling volume dynamics of a hearing device 12 is shown, which method may be performed by the hearing system 10 .

[0061] In step S10, the mobile device 14 is provided with a user interface 40 and the user is shown a volume modifier control element 44. The user may then select a new volume modifier value 46. When the user has selected a new volume modifier value 46, the selected volume modifier value 46 is sent from the mobile device 14 to the hearing device 12.

[0062] Alternatively, the user may utilize a user interface of the hearing device 12 (eg, the knob 28 ) to select a new volume modifier value 46 .

[0063] Finally, the new volume modifier value 46 is received in a computer program executed in the hearing device 12 , which performs the following steps.

[0064] Depending on whether the volume modifier value 46 is within the soft sound emphasizer range 54 or the loud sound limiter range 56 , the method continues with step S12 or step S14 .

[0065] In step S12, when the volume modifier value 46 is within the soft sound emphasizer range 54, the volume control curve 58 is modified to emphasize the soft sound. This can be done by increasing the output value and / or the range of output values ​​of the volume control curve 58 below the reference value 64 within the input range, for example, Figure 3 As shown in .

[0066] Output values ​​below the reference value 64 within the input range may be increased by adding an offset. The offset may be the offset value multiplied by the absolute value of the volume modifier value 46. All output values ​​of the volume control curve 58 below the reference value 64 may also be increased by an equal offset. For example, the output values ​​of the plateau range 62b may be increased equally by an offset such as that mentioned above. Also, the output values ​​of the volume control curve 58 within the first linear range 62a may be increased by the offset.

[0067] like Figure 3 As shown in FIG. 6 , the output value in the second linear range 62 c can also be increased, for example, by pivoting the second linear range 62 .

[0068] In addition, the output value of the volume control curve 58 above the reference value 64 within the input range may be reduced. For example, when the output value of the plateau range 62b increases, the slope of the second linear range 62c may be reduced so that the volume control curve 58 within the plateau range 62b and the second linear range 62c remain connected. In this case, the output value below the pivot point (which can be regarded as a reference value in this case) increases, and the output value above the pivot point decreases.

[0069] In step S14, when the volume modifier value 46 is within the loud sound limiter range 56, the volume control curve 58 is modified to limit or reduce the loud sound. This can be done by increasing the output value of the volume control curve 58 above the reference value 64 within the input range, for example, as Figure 4 As shown in .

[0070] This may be achieved by reducing the slope of the volume control curve 58 in the second linear range 62c above the plateau range 62b (ie within the second linear range 62c). The slope may be proportional to the volume modifier value.

[0071] In this case, output values ​​of the volume control curve 58 within the input range below the reference value 64 are not modified. The input range may include a stationary range 62b and a first linear range 62a.

[0072] In step S16, the modified volume control curve 58 is applied to the sound processor 22 of the hearing device 12. The sound signal (e.g., the sound signal acquired by the microphone 20) is processed by the hearing device 12 and in particular amplified, e.g., frequency-dependent amplified, according to the modified volume control curve 58. The input volume of the sound signal is determined and amplified as defined by the modified volume control curve 58. The hearing device 12 then outputs the processed sound signal using the sound output device 24.
