In addition, when the processor 221 is located in a cultural facility such as a soccer stadium, a baseball stadium, or a performance hall, the processor 221 may receive voice information transmitted from a communication device installed in the corresponding cultural facility through the communication unit 250 and provide it to the user. . In this case, since the sound signal received through the transmitter 211 includes ambient noise, the noise may be reduced or eliminated by passing through the digital signal processor 224.

As another embodiment, the processor 221 may adjust the characteristics of the transmitter 211 and/or the handset 240 according to altitude information in order to protect the eardrum of a user according to a change in height. Here, the altitude information may be received from an external device through the communicator 250.

The memory 222 may store a fitting parameter of the hearing aid device, a setting value received from an external device, information on a surrounding environment, a user preference value, a fitting parameter change history, and the like. Meanwhile, information stored in the memory 222 may be provided to the audiologist through a hearing aid fitting server (not shown). To this end, the hearing protection device may transmit information stored in the memory 222 to the fitting control device through the communicator 250.

The filter engine 223 is for filtering digital signals input through the signal detector 210 and/or the communicator 250, and is used to reduce or remove noise, feedback, etc. of the input signal. Filters may be included.

On the other hand, the communicator 250 is for performing wireless communication with an external device through a wireless communication channel. For example, in order to minimize power consumption of a hearing aid device, wireless communication with an external device is performed based on Bluetooth.

Alternatively, the communicator 250 may be included in the processor 221, and in this case, the processor 221 may be configured as a single chip.

The decoder 260 may decode a digital signal received through the communication device 250.

Therefore, when the hearing aid device according to the present invention is connected (or paired) with an external device such as a mobile phone or a fitting control device, the digital signal received (or streamed) from the external device through the communicator 250 is also similar to the analog signal. By passing through the digital signal processor 224 of the sound processor 220, it may be processed or processed according to a preset fitting parameter. Here, the fitting parameter is a parameter for calibrating the input signal to suit the user of the hearing aid device, and may be adaptively changed or adjusted according to a set value received from the external device. The set value may include set values for parameters related to noise reduction, directionality processing, and feedback cancellation. As an example, the setting values transmitted for each parameter are as follows.

1) Setting value for noise reduction

-Whether to use adaptive noise reduction to reduce gain other than the speech spectrum by recognizing noise

-Select Gain Reduction Algorithm (for example, Wiener Filter or Spectral Subtraction)

-Onset time: Noise response speed (from several seconds to more than 30 seconds)

-Offset time: Automatic noise removal recovery speed 5ms to several seconds)

-Whether to use impulsive sound smoothing and transient loudness reduction

2) Setting value for directional processing

-Whether to use dual microphones, number of microphones

3) Set value for feedback removal

-Degree of reduction in gain

-Adjustment frequency of the gain frequency response

-Whether to use frequency shifting, and the degree of frequency fluctuation

-Whether to use Feedback path cancelation

Therefore, according to the present invention, additional parameters related to noise reduction, directional processing, feedback control, etc., in addition to parameters related to dynamic range compression related to nonlinear amplification, which are generally used in fitting by a user, are used by external devices. Since it can be set, it is possible to fit the hearing aid device on its own and adaptively according to the surrounding environment without the aid of an audiologist.

To this end, the set value may be derived through a combination of location information acquired from an external device, information acquired by a sensor provided in the external device, and time information set in the external device, for example. Here, the location information includes GPS information obtained by a GPS (Global Positioning System) module provided in an external device, information obtained through communication between a beacon device fixedly installed at a specific location and the external device.

If it is confirmed that the external device is the current setting value for the surrounding environment, the set value for the sleep mode may be displayed on the external device or transmitted to the hearing aid device. As another example, if the sensing value of the acceleration sensor corresponds to'no movement', the sensing value of the noise sensor corresponds to'quiet' and the current time is determined to be'lecture time', the external device is set to the current surrounding environment. As a result, the set value for the lecture mode can be displayed on an external device or transmitted to the hearing aid device.

Meanwhile, the set value is derived through a combination of location information acquired from an external device, information acquired by a sensor provided in the external device, time information set in the external device, and information acquired by an external sensor linked to the external device. Can be. Here, the external sensor may be an external microphone, a noise sensor, etc. that are not generally attached to an external device. That is, the set value may be derived through a combination obtained by a peripheral device linked to the external device in addition to information collected by the external device itself.

In addition, the set value may include at least one of location information obtained from an external device, information obtained by a sensor provided in the external device, time information set in the external device, and information obtained by an external sensor linked to the external device. It may be derived through comparison with the set value of another user received from the auxiliary device fitting server. Here, the setting value of the other user is a setting value set by another user for the corresponding environment, and is uploaded to the hearing aid fitting server, and the setting value of the user is also a setting value for the corresponding environment by an external device. As the hearing aid device fitting server, it may be uploaded and shared with other users.

Meanwhile, the hearing aid device according to the present invention may be implemented as a first hearing aid device disposed on one ear of the user and a second hearing aid device disposed on the other ear of the user. Even in this case, the basic structures of the first hearing aid device and the second hearing aid device are the same as described above, but the first hearing aid device and the second hearing aid device may perform short-range wireless communication with each other through a communication device. For example, the first hearing aid device is information stored in the memory of the first hearing aid device through a communication device (fitting parameter setting value received from an external device, information on the surrounding environment, user preference value, fitting parameter change history, etc.) , An audio signal received from an external device, an analog signal received through a transmitter of the first hearing aid device, and the like may be transmitted to the second hearing aid device through a communication device of the first hearing aid device. When a set value for a fitting parameter is received from the first hearing aid device, the second hearing aid device may fit the second hearing aid device based on this. In addition, when the second hearing aid device receives an audio signal from the first hearing aid device, the second hearing aid device may process the audio signal using a digital signal processor and output it through the handset. In addition, when the second hearing aid device receives an analog signal received from the first hearing aid device from the first hearing aid device, the second hearing aid device may use this to adjust a signal output through the receiver of the second hearing aid device.

The hearing aid device according to the present invention may be driven by a battery built into the hearing aid device, or may be driven by electrical energy based on body energy such as body heat, pressure during walking, pulse, heart rate, and breathing of a user.

For example, the sensor 420 may include an illuminance sensor to obtain illuminance information, an acceleration sensor to obtain acceleration information, a microphone to obtain sound information, and the like. The sensor 420 may be maintained in an activated state, or may be activated or deactivated under the control of the fitting control device 400.

The processor 430 may determine whether a setting value for a fitting parameter corresponding to the location information of the hearing aid device exists among the fitting parameters for the user's hearing aid device. Here, the set value for the fitting parameter may be a set value for additional parameters such as noise reduction, directional processing, and feedback removal, not a set value for a parameter related to nonlinear amplification that is mainly used when fitting a hearing aid device.

For example, when the hearing aid device is operating and operates in a mode (automatic setting mode) for automatically setting a fitting parameter for the hearing aid device, or when a fitting parameter reset command is input by a user , It may be determined whether an existing setting value corresponding to the current location is stored based on the GPS information acquired by the GPS module or the current location information acquired through communication with a nearby beacon device. If there are a plurality of set values corresponding to the current location, the processor 430 uses at least one of the location information, information on the surrounding environment, current time information, and information acquired by an external sensor. Among the set values of the dogs, a set value to be applied to the hearing aid device can be derived. However, if it is determined that there is only one set value for the fitting parameter corresponding to the current location information, or a preset value selected by the user as a set value for the fitting parameter corresponding to the location information among the plurality of set values When it is determined that is present, a corresponding setting value may be determined as a setting value for corresponding location information.

On the other hand, when it is determined that the set value for the fitting parameter corresponding to the corresponding location information does not exist, the processor 430 determines the location information from the hearing aid fitting server (not shown), and About the surrounding environment acquired by using the set value provided by and current location information, the sensor 410 inside the fitting control device 400, and an external sensor (not shown) interlocking with the fitting control device 400. An initial setting process of generating at least one recommended setting value may be performed by using the setting value derived based on the information. When the initial setting process is performed, the processor 430 may perform a test on a setting value selected by the user from among the setting values of other users, the setting values provided by the audiologist, and the recommended setting values. In addition, when any one of the set values for which the test has been performed is selected by the user, the selected set value may be controlled to be transmitted to the hearing aid device through the communicator 450. Here, the test may be performed through a process of applying a corresponding set value to a preset test signal, a process of outputting a test signal to which the corresponding set value is applied, and a process of receiving an input from a user about whether the output test signal is audible. have. Thereafter, the processor 430 may control the setting value selected by the user among the recommended setting values to be uploaded to the hearing aid fitting server through the communicator 450. The setting value uploaded to the hearing aid fitting server is a setting value corresponding to corresponding location information and may be shared with other users.

The memory 440 may store a setting value of a fitting parameter corresponding to each location information and/or a setting value of another user received from the hearing aid fitting server. In addition, the memory 440 may include noise sounds (white noise, pink noise, etc.) for the treatment of tinnitus by the user. The noise sound may be transmitted to the hearing aid device through the communicator 450 and output through a receiver of the hearing aid device. In this case, the noise sound may not pass through the digital signal processor of the hearing aid device. That is, the noise sound may not be fitted by the hearing aid device.

The communicator 450 may transmit the set value derived by the processor 430 to the hearing aid device or may perform communication with an external sensor or a beacon device. To this end, the communicator 450 may include a WiFi chipset for WiFi-based wireless communication, a Bluetooth chipset for Bluetooth-based wireless communication, and the like. In addition, the communicator 450 may stream voice and/or music signals processed by the processor 430 to the hearing aid device.

Meanwhile, the communicator 450 may include a long-distance wireless communication module (not shown) for communication with a hearing aid fitting server. The processor 430 receives a recommended setting value for a current location, a setting value of another user, a setting value pre-selected by a user, etc. from the hearing aid fitting server through a telecommunication module, or information on the surrounding environment, user preference. Values, fitting parameter change history, etc. may be transmitted to the hearing aid fitting server.

The display 460 may display another user's setting value for the current location, a recommended setting value derived for the current location, and the like. For example, the display 460 may be implemented as a touch display, and in this case, the display 460 may receive a selection from a user from among a plurality of set values displayed for the current location.

Meanwhile, the fitting control device 400 may include an application for fitting a hearing aid device. The application may include codes for performing the functions of the processor 430 described above. For example, the application is a code that acquires location information of the hearing aid device using the GPS module 410, a code that acquires information about the surrounding environment of the hearing aid device using at least one sensor 410, fitting A code for acquiring time information of the control device 400, a code for determining whether a setting value for a fitting parameter corresponding to the current location information exists among fitting parameters for the hearing aid device, and a fitting parameter corresponding to the current location information When there are multiple set values, a code that derives a set value to be applied to the hearing aid device from among a plurality of set values using at least one of current location information, information about the surrounding environment, and time information, corresponding to the current location information When it is determined that there is only one set value for the fitting parameter, or when it is determined that there is a preset value selected by the user as a set value for the fitting parameter corresponding to the corresponding location information among a plurality of set values. When it is determined that there is no code for determining a set value for the corresponding location information and a set value for a fitting parameter corresponding to the corresponding location information, a code for performing an initial setting process, and the like may be included.

5 is a flowchart illustrating a method of operating a fitting control apparatus according to an embodiment of the present invention. Hereinafter, a process of fitting a hearing aid device by the fitting control device according to an embodiment of the present invention will be described in more detail with reference to FIG. 5.

First, the fitting control device may support both a manual setting mode or an automatic setting mode. In the manual setting mode, the fitting control device may perform fitting of the hearing aid device based on a user's command. In the automatic setting mode, the fitting control device may adaptively perform fitting of the hearing aid device.

When the hearing aid device is operating from the user, a reset command for the hearing aid device is input, or when operating in an automatic setting mode for the fitting parameter, the fitting control device communicates with GPS information and an external communication device fixedly installed at a specific location. Location information of the hearing aid device may be acquired based on at least one of information acquired through communication (S510). Here, the external communication device may be a base station for a wide area network (WAN), a beacon device performing wireless communication using a beacon, as a device fixedly installed at a specific location. In this case, when information such as a disaster situation and a local advertisement is received from the external communication device, the hearing aid device may provide the information to the user according to the user's selection (whether to allow information reception).

When the location information of the hearing assistance device is obtained, the fitting control device may determine whether a set value for a fitting parameter corresponding to the corresponding location information exists among the fitting parameters stored in the hearing assistance device (S520).

If it is determined that the setting value corresponding to the location does not exist in the fitting control apparatus, the fitting control apparatus may perform an initial setting procedure (S530). The initial setting procedure will be described later.

Meanwhile, if it is determined that a set value exists in the fitting control device, the fitting control device may determine whether there are a plurality of set values (S540). If it is determined that there are a plurality of set values, the fitting control device provides information acquired by a sensor provided in the fitting control device, time information set in the fitting control device, and an external sensor linked to the fitting control device. An optimal setting value to be applied to the hearing aid device among the plurality of setting values to obtain information on the surrounding environment of the hearing aid device by using the information obtained by the hearing aid device and the like, and based on the location information and the information on the surrounding environment By deriving and transmitting the derived set value to the hearing assisting device, the optimal set value may be applied to the hearing assisting device (S560). As long as the automatic setting mode is maintained, such a process may be repeatedly performed whenever a preset fitting parameter reset period is reached (S570 and S580).

However, if it is determined that there is only one set value for the fitting parameter corresponding to the corresponding position information, or a preset value selected by the user as a set value for the fitting parameter corresponding to the corresponding position information among the plurality of set values If present, the fitting control device may transmit a corresponding set value to the hearing assistance device so that the optimal fitting parameter is applied to the hearing assistance device (S550).

6 is a flowchart illustrating a method of performing an initial setting process by a fitting control apparatus according to an embodiment of the present invention. Hereinafter, the initial setting process for the current location will be described in more detail with reference to FIG. 6.

If there is no set value for the fitting parameter corresponding to the current location information, the fitting control device requests another user's set value for the location information to the hearing aid fitting server, while a sensor provided in the fitting control device By using the information acquired by the external sensor (illumination information, acceleration information, sound information, etc.), time information set in the fitting control device, and when there is an external sensor linked to the fitting control device, the information acquired by the external sensor is used. Information on the surrounding environment of the hearing aid device may be obtained. In addition, at least one recommended setting value may be provided to the user by displaying the setting value derived based on the setting value of the other user and the information on the surrounding environment on the display (S620).

Thereafter, when any one of the recommended setting values is selected by the user, the fitting control device may perform a test on the selected recommended setting value (S630). When it is selected that the recommended setting value for which the test has been performed is used by the user (S640), the fitting control device may transmit the finally selected recommended setting value to the hearing aid device so that the corresponding setting value is applied (S650). . If, as a result of the test, the user wants to test another set value, that is, when the user reselects the set value (S660), the set value testing process (S630) and the set value use check process (S640) are repeatedly performed. Can be. If the user does not want to apply all the recommended setting values, the existing setting values may be applied to the hearing aid device. That is, the fitting control device may not transmit any set values to the hearing aid device.

Thereafter, the fitting control device may upload the set value finally determined to be applied to the corresponding location to the hearing aid fitting server as the set value for the corresponding user (S680). And the uploaded settings can be shared with other users. Accordingly, the hearing aid fitting server may continuously provide improved environment settings based on the set value uploaded from the fitting control device.
