SYSTEM AND METHOD FOR INTERACTIVE MOBILE FITTING OF HEARING AIDS

FIELD

The present disclosure relates to hearing aids. More specifically, the present disclosure relates to a system that reduces the complexity of modern digital hearing aid fittings and configuration data sets to a conceptually simple user interface, manageable by a hearing aid user, and available as an application on a mobile device, such as a smart-phone or tablet computer. The mobile device has a wireless connection to the hearing devices allowing configuration data to be communicated.

BACKGROUND

Hearing aids (HA) are typically customized for specific users by manufacturers and hearing care professionals (HCP). These customizations improve comfort and acoustic performance particular to a user's unique hearing impairment. The customizations include physical modifications to the device and configuration of electro-acoustic characteristics.

Personal sound amplification products (PSAP) and other in-ear devices that stream audio or amplify sounds with ambient noise features are typically distributed directly to a consumer, without assistance of a hearing care professional. Customizations made available to the user are typically limited to basic adjustments, such as volume control, low resolution equalization, and program selection among pre-programmed generic fittings.

The distinction between hearing aids and personal sound amplification products is disappearing with new regulations, new modes of distribution, and new technological capabilities that bridge the gap between these former U.S. Food and Drug Administration (FDA) designations. For purposes of the present disclosure, personal sound amplification products and other in-ear devices that stream audio or amplify sounds with ambient noise features are considered to be in the same class as hearing aids.

Remote control devices and smart-phone applications are currently available, which allow a user to make basic adjustments to the hearing aid device configuration, such as volume control, program selection, or basic equalization. Some applications also provide for remote communication between the user and a hearing care professional, where the hearing care professional can prepare and send a digital package of fitting information to the user's mobile device, which the user can then load into the hearing aid to change its electro-acoustic performance.

In digital hearing aid devices, the configuration data set can be large and complex, with thousands of parameters. Compression hearing aids have arrays of data to define a user's unique dynamic range and comfortable listening levels at many frequencies and in multiple compression channels. Algorithms for improved hearing in noisy, reverberant, or windy conditions, for example, contribute additional parametric complexity. Fitting software used by hearing care professionals provide access to a wide range of adjustments for maximal freedom to find solutions for a wide range of user problems. This type of fitting process can be confusing and time consuming without professional training. Furthermore, large data sets, which must be written to the hearing aid, introduce time delays long enough to prevent incremental and interactive adjustments. At the root, these adjustments are all based on the user's perceptual judgment of loudness and audibility.

Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of such systems with some aspects of the present disclosure as set forth in the remainder of the present application.

These and other advantages, aspects and novel features of the present disclosure, as well as details of an illustrated embodiment thereof, will be more fully understood from the following description and drawings.

DETAILED DESCRIPTION

Embodiments of the present technology provide a system and method for interactive mobile fitting of hearing aids. Aspects of the present disclosure provide the technical effect of allowing a user to self-fit hearing aids without hearing care professional assistance. Various embodiments provide the technical effect of increasing user capability to provide improved adjustments that were formerly only possible with assistance from hearing care professionals. Certain embodiments provide the technical effect of making adjustments of the acoustic response in substantially real-time such that a user can hear the result of the adjustments substantially in real-time (i.e., within 500 milliseconds (ms) of the adjustment being made in the application).

Aspects of the present disclosure provide the technical effect of enabling remotely-located hearing care professionals providing telehealth applications to assist a user to create fittings or make adjustments interactively. Various embodiments leverage the training and experience of the hearing care professional to know which adjustments to make for particular hearing difficulty situations. Usage patterns and other situational data may be uploaded to a central server or database, for research and analysis contributing to continuous improvement of sound processing methods.

Aspects of the present disclosure provide the technical effect of reducing complex multi-dimensional arrays of data to smooth parametric curves on a grid that can be reshaped by a user, for example, by touching and sliding the graph displayed on the touch screen. Various embodiments provide the technical effect of using a reduced sized data set of parameters to specify the fitting curves, limited to a subset of the data for a fitting instead of the complete data set used by the runtime code in the hearing aid sound processors. Certain embodiments provide the technical effect of sending adjustments to the hearing aid devices in a flow-controlled stream of reduced sized packet transfers, which are interpreted and elaborated on the hearing aid device into the complete data set used for real-time audio signal processing. Aspects of the present disclosure provide the technical effect of performing computation to extrapolate and interpolate at both the mobile device (via the application) and by the hearing aid devices to reduce the bandwidth requirement in the communications channel between the mobile device and hearing aid devices. This redundant computation may assist the system in responding fast enough for the interactive user experience.

FIG. 1 illustrates a block diagram of an exemplary system 100 configured to provide interactive mobile fitting of hearing aids 130. Referring to FIG. 1, the system 100 includes a mobile smart-device (also referred to as a mobile device) 110, a hearing aid 130, a hearing care professional (HCP) system 150, and one or more servers 160.

The mobile smart-device 110 may comprise, for example, a smart phone, a tablet computer, or other handheld electronic device capable of communication with the hearing aid 130 via a wireless connection, such as Bluetooth, short-range, long range, Wi-Fi, cellular, personal communication system (PCS), or any suitable wireless connection. The mobile smart-device 110 may communicate with the one or more servers 160 via a wireless network and the Internet, for example. The wireless network may be one or more of a cellular, PCS, Wi-Fi, or other wireless communication network.

The mobile smart-device may include a display 111, user input devices 111, a memory, one or more processors 113, one or more communication components 112, and the like. The display 111 may be any device capable of communicating visual information to a user. For example, a display 111 may include a liquid crystal display, a light emitting diode display, and/or any suitable display. The display 111 can be operable to display information from a software application, such as an interactive mobile hearing aid fitting application, or any suitable information. In various embodiments, the display 111 may display information provided by the one or more processors 113, for example.

The user input device(s) 111 may include a touchscreen, button(s), motion tracking, orientation detection, voice recognition, a mousing device, keyboard, camera, and/or any other device capable of receiving a user directive. In certain embodiments, one or more of the user input devices 111 may be integrated into other components, such as the display 111, for example. As an example, user input device may include a touchscreen display 111.

The memory (not shown) may be one or more computer-readable memories, for example, such as compact storage, flash memory, random access memory, read-only memory, electrically erasable and programmable read-only memory and/or any suitable memory. The memory may include databases, libraries, sets of information, or other storage accessed by and/or incorporated with the one or more processors 113, for example. The memory may be able to store data temporarily or permanently, for example. The memory may be capable of storing data generated by the one or more processors 113 and/or instructions readable by the one or more processors 113, among other things. In various embodiments, the memory stores information related to an interactive mobile hearing aid fitting application, for example.

The communication component(s) 112 allow communication between the mobile smart-device 110 and other external systems, such as the hearing aid 130 and the server(s) 160, for example. The communication component(s) 112 may include transceivers, such as Bluetooth, short-range, long range, Wi-Fi, cellular, personal communication system (PCS), or any suitable transceiver.

The one or more processors 113 may be one or more central processing units, microprocessors, microcontrollers, and/or the like. The one or more processors 113 may be an integrated component, or may be distributed across various locations, for example. The one or more processors 113 may be capable of executing a software application, receiving input information from a user input device 111 and/or communication connection(s) 112, and generating an output displayable by a display 111, among other things. In certain embodiments, the one or more processors 113 may communicate via communication connection(s) 112 with servers 160 to execute an interactive mobile hearing aid fitting application, for example. In an exemplary embodiment, the one or more processors 113 may communicate via communication connection(s) 112 with the hearing aid 130 to program the hearing aid with user-adjusted settings. For example, the one or more processor 113 may send adjustments to the hearing aid devices 130 in a flow-controlled stream of reduced sized packet transfers, which are interpreted and elaborated on the hearing aid device 130 into the complete fitting data set used for real-time audio signal processing.

The one or more processors 113 may comprise suitable logic, circuitry, interfaces, or code configured to reduce complex multi-dimensional arrays of data to smooth parametric curves on a grid that can be reshaped by a user. The processor(s) 113 may be configured to receive a reduced size fitting data set as communications 119 received from a hearing aid 130 via a communications component 112 at the mobile device 110. The reduced size fitting data set may be a set of sampling points from a complete fitting data set. The complete fitting data set may be a multi-dimensional array of fitting data. For example, the multi-dimensional array of fitting data may comprise a number of curves, such as a most comfortable level (MCL) curve, a maximum output level (MOL) curve designed to keep output audio levels below a user's loudness discomfort level (LDL), a maximum gain curve, a minimum gain curve, an acoustic audibility curve, an otoacoustic emissions (OAE) measurement curve, and the like. Each of the curves of the complete fitting data set may comprise a number of data points, such as 32-128 data points or any suitable number of data points. The reduced size fitting data set may comprise a set of sampling points (e.g., 9 sample points or any suitable number of sampling points less than a total number of sampling points from a curve of the complete fitting data set) from one of the curves of the complete fitting data set, such as the most comfortable level (MCL) curve or any suitable curve. The complete fitting data set may be manufacturers settings stored in the hearing aid 130 as part of the manufacturing process. Other subsequent processes may be used to further configure the hearing aids prior to interactive end-user adjustments. For example, fittings facilitated by a hearing care professional via the hearing care professional system 150 executing advanced fitting software may be used to generate the complete fitting data. As another example, the complete data set may be generated based on fitting algorithms for self-assessment, to create initial fittings based on an audiogram, according to a fitting rule, or rationale. The complete data set may also include fittings optimized through deep learning algorithms designed to discover user-preferred settings in a wide range of sound environments. Any or all of these initial fitting processes may be implemented on the mobile device 110, along with the interactive adjustment capability as described below.

The processor(s) 113 may comprise control logic 114 configured to control a flow of data between the processor(s) 113 and the other components of the mobile device 110, such as the communications component 112 and the touchscreen display 111. The processor(s) 113 may comprise suitable logic, circuitry, interfaces, or code configured to interpolate and generate dependent data 116 from the reduced size fitting data set 115 (also referred to as condensed fitting parameters as shown in FIG. 1). For example, the processor(s) 113 may interpolate 116 the reduced size fitting data set 115 by generating piecewise polynomial curves between sampling points of the set of sampling points to generate a continuous fitting curve represented by a high resolution array of discrete samples presented as a smooth curve 117 at the touchscreen 111 of the mobile device 110. The processor(s) may additionally and/or alternatively perform linear interpolation or any suitable interpolation method to generate the continuous fitting curve represented by a high resolution array of discrete samples presented as a smooth curve 117 at the touchscreen 111 of the mobile device 110. In various embodiments, the processor(s) may comprise suitable logic, circuitry, interfaces, or code configured to generate dependent data from the continuous fitting curve. As an example, the processor(s) may be configured to generate an MOL curve, a maximum gain curve, a minimum gain curve, and/or any suitable curve based on an interpolated MCL continuous fitting curve. The dependent data curves may additionally and/or alternatively be presented 117 at the touchscreen 111 of the mobile device 110.

The processor(s) 113 may be configured to present the continuous fitting curve with user interface objects at the display 111 of the mobile device 110. The user interface objects may each correspond with one sampling point from the set of sampling points of the reduced size fitting data set. The user interface objects may include visual indications of the objects or may be hidden objects. For example, the user interface objects may include sliders, handles, textual or numerical indicators, buttons, drop down menus, or the like presented at the display 111 for adjusting a value of the corresponding sampling point. As another example, the user interface objects may not include a visual indicator. For example, the user interface objects may be the sampling points on the continuous fitting curve presented in a same manner as the remainder of the continuous fitting curve. The user interface objects may be manipulated via a user input device (also referred to as a user interface) to increase or decrease a value of the sampling point. For example, a user finger or pointing device (e.g., mousing device) may be used to drag a user interface object up or down to increase or decrease the value of the sampling point. As another example, a user interface object may be selected and a button or knob may be manipulated to increase or decrease the value of the sampling point corresponding with the user interface object.

Additionally and/or alternatively, the processor(s) 113 may be configured to present a shape representing the continuous fitting curve with user interface objects at the display 111 of the mobile device 110. The shape may be a two-dimensional shape or three-dimensional shape. The shape may be a square, cube, circle, oval, or any suitable shape. The shape may correspond with the shape of an object, such as a soccer ball, star, apple, or any suitable object. The user interface objects may be sides, corners, edges, outer boundaries, points, or any suitable portions of the shape. The user interface objects may be manipulated, rotated or otherwise selected by the user through gesture controls such as dragging one's finger around the user interface to move, rotate or otherwise change the shape that appears on the touchscreen. The different sides or facets of the shape may be designated by different colors, shading, numbers, or any suitable indicator to help visualize which part of the shape is selected and active. These different sides or facets of the shape can in turn be mapped to sampling point combinations representing different configurations of the continuous fitting curve.

The processor(s) 113 may be configured to receive a user input 118 manipulating at least one of the user interface objects. The user input 118 adjusts a value of the one or more sampling points corresponding to the at least one of the user interface objects. The processor(s) 113 may be configured to generate an updated reduced size fitting data set 115 based on the received user input 118. The processor(s) 113 may comprise suitable logic, circuitry, interfaces, or code configured to interpolate and generate dependent data 116 from the updated reduced size fitting data set 115 as discussed above to update the continuous fitting curve 117 and any dependent data presented at the display 111 of the mobile device. The processor(s) 113 may be configured to communicate 119 the updated reduced size fitting data set 115, via the mobile device communication component 112, to the hearing aid 130 for application to input audio at the hearing aid 130 in substantially real-time (i.e., within 500 ms), such that a user can hear the result of the adjustments substantially in real-time.

The hearing aid 130 comprises an audio input 131, one or more receivers 132, memory 134, one or more hearing aid processors 135, and communication component(s) 133. The audio input 131 may comprise one or more microphones 141, streaming digital audio 142 receiving via communication component(s) 133, and/or any suitable audio input. The one or more microphones 141 are configured to receive sound exterior to an ear canal. The microphone(s) 141 convert the sound to electrical signals and provide the electrical signals to the one or more hearing aid processors 135 via the audio input 131. Additionally and/or alternatively, the audio input 131 may provide the one or more hearing aid processors 135 with streaming digital audio 142 or any suitable audio input. The one or more hearing aid processors 135 modify the sound level 139 by applying elaborated parameters 138 retrieved from memory 134 and/or generated based on reduced fitting data sets provided by the mobile smart-device 110. The one or more hearing aid processors 135 pass the electrical signals having the modified sound level to the receiver 132. The receiver 132 converts the electrical signals to sound, which is communicated from the receiver 132 to a user's ear canal.

The memory 134 may be a nonvolatile memory or any suitable memory configured to store a complete fitting data set, substitute complete fitting data set(s), reduced size fitting data sets, hearing aid processing instructions, and/or any suitable information.

The communication component(s) 133 allow communication between the hearing aid 130 and other external systems, such as the mobile smart-device 110 and the hearing care professional system 150, for example. The communication component(s) 133 may include wired and/or wireless communication interfaces. For example, the hearing aid 130 may communicate with the hearing care professional system 150 via wired communications, and may communicate with the mobile device 110 via wireless communications. The communications component 133 may include transceivers, such as Bluetooth, short-range, long range, Wi-Fi, cellular, personal communication system (PCS), or any suitable transceiver, configured to wirelessly communicate with the communications component 112 of the mobile device 110.

The hearing aid processor(s) 135 may be configured to generate, and/or retrieve from memory 134, a reduced size fitting data set from the complete fitting data set. The reduced size fitting data set 136 may be communicated 140 to the mobile device 110 via the communications component 133. The hearing aid processor(s) 135 may be configured to receive an updated reduced size fitting data set 136 as communications 140 received from the mobile device 110 via a communications component 133 at the hearing aid 130. The hearing aid processor(s) 135 may be configured to store the updated reduced size fitting data set 136 at memory 134. The hearing aid processor(s) 135 may comprise suitable logic, circuitry, interfaces, or code configured to interpolate and generate dependent data 137 from the updated reduced size fitting data set 136. For example, the hearing aid processor(s) 135 may interpolate 137 the reduced size fitting data set 115 by generating piecewise polynomial curves between sampling points of the set of sampling points and/or by any suitable interpolation method. The hearing aid processor(s) 135 may comprise suitable logic, circuitry, interfaces, or code configured to generate dependent data from the interpolated curve.

The hearing aid processor(s) 135 may be configured to generate a substitute complete fitting data set based on the interpolated curve and dependent data. In various embodiments, the substitute complete fitting data set is stored at memory 134 in addition to and/or separate from the original complete fitting data set. In an exemplary embodiment, the substitute complete fitting data set is stored at memory 134 in response to a command from the mobile device 110. In certain embodiments, the substitute complete fitting data set may be stored as a program that is selectable at the mobile device 110 for application at the hearing aid 130. The hearing aid processor(s) 135 may comprise suitable logic, circuitry, interfaces, or code configured to generate elaborated parameters for digital signal processing 138. For example, the hearing aid processor(s) 135 may be configured to reformat the substitute complete fitting data set for application to the input audio. The hearing aid processor(s) 135 may comprise suitable logic, circuitry, interfaces, or code configured to apply the elaborated parameters to input audio to generate modified audio 139. The modified audio may be output by the receiver 132 of the hearing aid 130 into an ear canal of the user.

In various embodiments, the one or more hearing aid processors 135, and communication components 133 may share various characteristics with the memory, one or more processors 113, and communication components 112 as described about with respect to the mobile smart-device 110.

The hearing care professional system 150 may include a personal computer, workstation, and/or any suitable computing device operated by a hearing care professional to communicate with the hearing aid 130 and server(s) 160. For example, the hearing care professional system 150 may be configured to replace a default manufacturer complete fitting data set or other complete fitting data set with a new complete fitting data set specific to a particular user of the hearing aid 130. In various embodiments, the hearing care professional system 150 may access substitute complete fitting data sets generated by a user of the mobile device 110 and stored in memory 134 of the hearing aid 130. The hearing care professional system 150 may communicate with the server(s) 160 via the Internet or any suitable communication connection to store or retrieve patient data, complete fitting data sets, hearing aid device information, purchase history, and/or any suitable information.

The one or more servers 160 may include web servers, database servers, and/or application servers, for example. The servers 160 may be configured to store a complete fitting data set, substitute complete fitting data sets, updated reduced fitting data sets, client data, and the like. For example, the mobile device 110 may communicate with the one or more servers 160 via the Internet or any suitable communication connection to provide updated reduced fitting data sets and/or to receive updated reduced fitting data sets prepared by a hearing care professional. As another example, the hearing care professional system 150 may communicate with the one or more servers 160 via the Internet or any suitable communication connection to provide or retrieve client data, complete fitting data sets, substitute complete fitting data sets, hearing aid device information and purchase history, and/or any suitable information. As another example, intensive computations may be offloaded from the hearing aid 130 or mobile device 110 to servers 160, and the computational results returned to the mobile device 110 and hearing aid 130 for real-time application.

In operation, the hearing aid 130 and mobile smart-device 110 establish a data connection, such as via Bluetooth or any suitable data connection. The mobile smart-device 110 may be configured to read condensed fitting parameters (i.e., reduced fitting data set) from the hearing aid 130. The condensed fitting parameters may be modified by the user via the mobile device user input device, such as a touchscreen 111, and written to the hearing aid 130 by the mobile smart-device 110.

A processor 135 of the hearing aid converts the condensed fitting parameters into the elaborated parameters for DSP (reformatted complete fitting data set). Either the reduced fitting data set, the complete fitting data set, or both may be stored in the nonvolatile memory 134 of the hearing aid 130. In addition, data sets may be stored in the hearing care professional system 150 and/or in a central database via web services 160. The hearing care professional system 150 and mobile smart device 110 may also have access to the same client data via the web service server(s) 160. The present disclosure primarily refers to a user's ability to interactively manipulate elaborated DSP parameters via a wireless connection. The redundant computation on a hearing aid 130 and mobile smart-device 110 reduce the data rate across the wireless connection.

FIG. 2 is a flow chart 200 illustrating exemplary steps 202-228 that may be utilized for providing interactive mobile fitting of hearing aids 130, in accordance with embodiments of the present technology. Referring to FIG. 2, there is shown a flow chart 200 comprising exemplary steps 202 through 228. Certain embodiments may omit one or more of the steps, and/or perform the steps in a different order than the order listed, and/or combine certain of the steps discussed below. For example, some steps may not be performed in certain embodiments. As a further example, certain steps may be performed in a different temporal order, including simultaneously, than listed below.

At step 202, a mobile device 110 receives a reduced size fitting data set from a hearing aid 130. For example, at least one processor 113 of the mobile device may be configured to receive a reduced size fitting data set as communications 119 received from a hearing aid 130 via a communications component 112 at the mobile device 110. The reduced size fitting data set may be a set of sampling points from a complete fitting data set stored at memory 134 of the hearing aid 130.

At step 204, at least one processor 113 of the mobile device 110 interpolates the reduced size fitting data set into a continuous fitting curve 117. For example, the at least one processor 113 may be configured to interpolate 116 the reduced size fitting data set 115 by generating piecewise polynomial curves between sampling points of the set of sampling points, or any suitable interpolation method, to generate the continuous fitting curve represented by a high resolution array of discrete samples presented as a smooth curve 117 at a display 111 of the mobile device 110.

At step 206, the at least one processor 113 of the mobile device 110 presents the continuous fitting curve 117 with user interface objects at a display 111 of the mobile device 110. For example, the user interface objects may each correspond with one sampling point from the set of sampling points of the reduced size fitting data set. The user interface objects may include visual indications of the objects or may be hidden objects. For example, the user interface objects may include sliders, handles, textual or numerical indicators, buttons, drop down menus, or the like presented at the display 111 for adjusting a value of the corresponding sampling point. As another example, the user interface objects may not include a visual indicator. For example, the user interface objects may be the sampling points on the continuous fitting curve presented in a same manner as the remainder of the continuous fitting curve. In various embodiments, the continuous fitting curve may be represented by a shape presented at the display 111 as described below with respect to FIGS. 11 and 12. For example, the shape may be a two-dimensional shape or three-dimensional shape. The shape may be a square, cube, circle, oval, or any suitable shape. The shape may correspond with the shape of an object, such as a soccer ball, star, apple, or any suitable object. The user interface objects may be sides, corners, edges, outer boundaries, points, or any suitable portions of the shape. The user interface objects may be different sides or facets of the shape, which in turn may be mapped to sampling point combinations representing different configurations of the continuous fitting curve.

At step 208, a user input 118 manipulating at least one of the user interface objects is received at the mobile device 110 to generate an updated reduced size fitting data set. For example, the user interface objects may be manipulated via a user input device to increase or decrease a value of the sampling point. As another example, the user interface objects of a shape representing the continuous fitting curve may be manipulated, rotated or otherwise selected via a user input device to adjust values of one or more sampling points. The at least one processor 113 of the mobile device 110 may be configured to generate an updated reduced size fitting data set 115 based on the received user input 118.

At step 210, the mobile device 110 communicates the updated reduced size fitting data set to the hearing aid 130. For example, at least one hearing aid processor 135 of the hearing aid 130 may be configured to receive an updated reduced size fitting data set 136 as communications 140 received from the mobile device 110 via a communications component 133 at the hearing aid 130.

At step 212, at least one hearing aid processor 135 of the hearing aid 130 generates a substitute complete fitting data set based on the updated reduced size fitting data set. For example, the at least one hearing aid processor 135 may interpolate 137 the reduced size fitting data set 115 by generating piecewise polynomial curves between sampling points of the set of sampling points and/or by any suitable interpolation method. The at least one hearing aid processor 135 may be configured to generate a substitute complete fitting data set based on the interpolated curve.

At step 214, the at least one hearing aid processor 135 applies the substitute complete fitting data set to input audio to generate modified audio. For example, the at least one hearing aid processor 135 may be configured to generate elaborated parameters for digital signal processing 138 by reformatting the substitute complete fitting data set for application to the input audio. The at least one hearing aid processor 135 may apply the elaborated parameters to input audio to generate modified audio 139.

At step 216, the hearing aid 130 outputs the modified audio. For example, the modified audio may be output by a receiver 132 of the hearing aid 130 into an ear canal of the user.

At step 218, if a user is not satisfied with the modified audio, the process proceeds to step 220 as described below. If the user is satisfied with the modified audio, the process proceeds to step 226 as described below.

At step 220, a user may continue making changes to the continuous fitting curve as modified by the previous user input manipulations by returning to step 208 to provide additional user input manipulations if the user is not satisfied with the modified audio. If the user does not want to continue making changes, the process proceeds to step 222.

At step 222, the user may provide a selection via the user interface 111, 900, 910 to forget the session changes 930. The process 200 then returns to step 206 where the continuous fitting curve prior to the user manipulations is presented with the user interface objects at the display 111 of the mobile device 110. If the user does not want to forget the session changes and return to the continuous fitting curve prior to user manipulations, the process 200 proceeds to step 224.

At step 224, the user may provide a selection via the user interface 111, 900, 910 to revert back to the original complete fitting data set (e.g., prior to any substitute complete fitting data set being generated). The process 200 then returns to step 202 where a reduced size fitting data set corresponding to the original complete fitting data set is received from the hearing aid 130 at the mobile device 110. If the user does not want to revert back to the original complete fitting data set, the process returns to step 218.

At step 226, the user may provide a selection via the user interface 111, 358, 720 of the mobile device 110 to store the substitute complete fitting data set at nonvolatile memory 134 of the hearing aid 130. In various embodiments, the user may select to store the substitute complete fitting data set as a program. For example, the substitute complete fitting data may be stored as a default program, a program for noisy environments, a program for music listening, a program for windy environments, or any suitable program. The stored program may be selected via the user interface 111 of the mobile device 110 for application by the hearing aid 130 to input audio.

At step 228, the process 200 ends.

Although FIGS. 3-10 illustrate an acoustic frequency range from 250 Hz to 6000 Hz, other frequency ranges may be provided, such as for devices having frequency ranges extending up to 20,000 Hz, among other things.

Referring to FIG. 3, a user interface screenshot 300 of an exemplary comfort target 320 for a left hearing aid, by frequency, with a default target 310 predicted by audiogram is shown. For example, the default target curve 310 may correspond with the original complete fitting data set and the comfort target curve 320 may correspond with the substitute complete fitting data set as modified by a user of the mobile device 110. The default target curve 310 and comfort target curve 320 may be most comfortable level (MCL) curves, or any suitable curves. The user interface 300 may include user selectable tools or options 350, such as to select display of curves corresponding with a left hearing aid 351, a right hearing aid 352, both hearing aids 353, display of dependent data curves 354, an option to perform an automatic sequential sweep of audio stimulus test signals across a range of frequencies 355, an option to modify the comfort target curve 356, a program selector option 357, an option to save the substitute complete fitting data set at the hearing aid 358, an option 359 to revert to the original complete fitting data set 920 and/or forget session changes 930, an option to lock programming 360, or any suitable tools or options. In various embodiments, the comfort target curve 320 may be modifiable by a user selecting a sampling point of the curve 320 and dragging the sampling point up or down. As an example, the sampling points may correspond with user interface objects that may be hidden (as shown in FIG. 3) or displayed (as shown in FIGS. 5 and 6). Modifications of the sampling points results in the real-time update of the continuous curve 320 by interpolation of the modified sampling points. The modified sampling points are provided as an updated reduced size fitting data set communicated to the hearing aid 130 for application to input audio. In an exemplary embodiment, the user interface 300 may be presented in response to a user selected option or tool 351.

Referring to FIG. 4, a user interface screenshot 400 of an exemplary advanced view of a right hearing aid most comfortable level (MCL) 420 with a maximum output level (MOL) target curve 430 and a maximum gain curve 440 is shown. The user interface 400 may display a default target curve 410 corresponding to the original complete fitting data set, an MCL curve 420 corresponding with the substitute complete fitting data set as modified by a user of the mobile device 110, and curves 430, 440 dependent on the MCL curve 420, such as an MOL target curve 430, a maximum gain curve 440, a minimum gain curve, and/or any suitable dependent curve. As discussed above with respect to FIG. 3, the MCL curve 420 may be modifiable by a user selecting a sampling point of the curve 420 and dragging the sampling point up or down. As an example, the sampling points may correspond with user interface objects that may be hidden (as shown in FIG. 4) or displayed (as shown in FIGS. 5 and 6). Modifications of the sampling points results in the real-time update of the continuous curve 420 and dependent curves 430, 440 by interpolation of the modified sampling points. The modified sampling points are provided as an updated reduced size fitting data set communicated to the hearing aid 130 for application to input audio.

The user interface 500 may include a left hearing aid MCL curve 510, a right hearing aid MCL curve 520, and a plurality of user interface objects 530, 540 each corresponding to a sampling point of a reduced size fitting data set. The user interface objects 530, 540 may include a slider 530 operable to slide within a sliding range 540 that defines an adjustment range of the sampling point. Although sliders 530 are shown for adjusting the sampling point of each band, other graphical user interface elements may be implemented, such as handles (as shown in FIG. 6), hidden user interface objects (as described above with respect to FIGS. 3 and 4), selectable numerical or textual levels, increase and decrease buttons, drop down menu selections, and the like. In various embodiments, the hearing aid 130 may be configured to play source tones in a narrow band, and a user may adjust each frequency range to loudness such that all bands are perceived as equal loudness at the most comfortable level. The process may be performed monaurally (i.e., for each hearing aid side). In an exemplary embodiment, the user interface 500 may be presented in response to a user selected option or tool 356. Similar to real-ear measurement (REM) techniques, providing in-situ loudness balancing eliminates the need for estimates and transformations used in traditional fitting algorithms, such as using population normal data to predict MCL, or using standardized transformations to account for the acoustic effects of a unique ear canal on free-field audio input.

Referring to FIG. 6, a user interface screenshot 600 of exemplary selectable binaural balance adjustments for a plurality of narrow frequency bands is shown. The user interface 600 may include a right hearing aid default MCL target curve 610 corresponding to the original complete fitting data set and a right hearing aid MCL curve 620 corresponding with the substitute complete fitting data set as modified by a user of the mobile device 110.

The user interface objects 630, 640 may include handles operable to be dragged up or down to adjust a corresponding sampling point. Although handles 630, 640 are shown for adjusting the sampling point of each band, other graphical user interface elements may be implemented, such as sliders (as shown in FIG. 5), hidden user interface objects (as described above with respect to FIGS. 3 and 4), selectable numerical or textual levels, increase and decrease buttons, drop down menu selections, and the like. In various embodiments, the hearing aid 130 may be configured to play source audio in narrow bands in both the left and right hearing aids simultaneously, and a user may adjust the binaural balance until the sounds are perceived as located in the medial plane. In certain embodiments, the user interface object 640 corresponding with the current narrow band being played may be enlarged as shown in FIG. 6. In an exemplary embodiment, the user interface 600 may be presented in response to a user selected option or tool 355.

The user interface 700 may include a prompt 710 for selecting a program 720 to adjust. For example, the prompt 710 may be presented in response to a user selected option or tool 357. Adjustments may be made for independent programs in the hearing aid 130, such as a noisy environment program, a windy environment program, a music listening program, a standard program, and/or any suitable program. In various embodiments, each program 720 is an independent set of configuration parameters, optimized for unique acoustic environments and selected by the user. The interactive mobile hearing aid fitting application provides an option for selecting the particular program 720 being adjusted. In certain embodiments, the interactive mobile hearing aid fitting application may similarly provide options for storing a substitute complete fitting data set as a program and/or selecting a program to apply at the hearing aid 130.

Referring to FIG. 8, a user interface screenshot 800 of an exemplary indication 810 that selected settings are being stored to the hearing aid is shown. For example, a user may determine when to commit the substitute complete fitting data to nonvolatile memory 134 in the hearing aids 130. In an exemplary embodiment, the user interface 800 may be presented in response to a user selected option or tool 358.

Referring to FIG. 9, a user interface screenshot 900 of exemplary user-selectable options 910 for discarding setting changes 930 or reverting to previous settings 920 is shown. The user interface 900 may include a prompt 910 providing options to revert to an original complete fitting data set 920, discarding a substitute complete filing data set 930, canceling the prompt 910, and/or any suitable option. The prompt 910 may be presented in response to a user selected option or tool 359. For example, the interactive mobile hearing aid fitting application may include options for allowing users to restart from a safe initial condition, in case the user has deviated from a useful configuration.

Referring to FIG. 10, a user interface screenshot 1000 of an exemplary user-selectable option 1010 to lock programing to temporarily prevent accidental modifications to a fitting is shown. For example, the interactive mobile hearing aid fitting application may include an option 1010 for locking the screen, to temporarily prevent accidental modifications to a fitting that has been settled. The option 1010 may be presented in response to a user selected option or tool 360.
