First, when the user terminal 300 accesses the web server 400, the user terminal 300 displays a web page including a hearing information input window (S410). The user inputs hearing information in the hearing information input window (S420). In this case, the hearing information includes a hearing test result according to a divided frequency band or various situations. In addition, the user may further input user information such as a user name, a user age, a phone number of the user's portable terminal 200, as well as hearing information.

The web server 400 transmits the received hearing information to the fitting server 500 (S430). Here, the web server 400 may store the hearing information in the user database 450, and the fitting server 500 may acquire the hearing information in the user database 450.

The fitting server 500 generates a fitting parameter by using the hearing information (S440). The fitting server 500 calculates a fitting parameter for accurately fitting the amplification degree and the maximum output range for each frequency band based on the hearing information of the user. The fitting parameter is designed to set an optimized amplification or gain value for each channel in consideration of frequency characteristics. In particular, by detecting the hearing loss band frequency of the user from the hearing information, to set the amplification degree or gain value optimized for the hearing loss frequency, and to minimize the noise.

The fitting server 500 transmits the generated user-specific fitting parameters to the web server 400 (S450).

In a state where the user terminal 300 is connected to the web server 400, the user connects the portable terminal 200 to the user terminal 300 to download fitting parameters (S460). When the fitting parameter is stored in the portable terminal 200, the hearing aid program to which the fitting parameter is applied in the hearing aid mode is executed through the portable terminal 200 (S470). In addition, a user wearing the ear microphone 100 in short range communication with the portable terminal 200 may hear a voice signal fitted by a hearing aid program.

That is, in the state where the portable terminal 200 is set to the hearing aid mode, the voice signal input to the microphone 110 of the microphone 100 is then transferred to the portable terminal 200 and processed by the hearing aid program. The hearing aid processed voice signal is then transmitted to the user's ear through the speaker 130 of the microphone 100 so that the user can hear the hearing aided voice signal in response to the hearing condition. The user may further perform fitting processing in detail for convenience by using an equalizer installed in the portable terminal 200 or the ear microphone 100.

5 is a flowchart illustrating a fitting method of a hearing aid system using a portable terminal according to a second embodiment of the present invention.

As in the first embodiment of the present invention, when the user terminal 300 accesses the web server 400, the user terminal 300 displays a web page including a hearing information input window (S510). The user inputs hearing information and phone number information of the portable terminal 200 in the hearing information input window (S520). Here, the user may further input user information such as user name, user age, user ID, as well as hearing information and phone number information.

The web server 400 transmits the received hearing information to the fitting server 500 (S530). Here, the web server 400 may store the hearing information in the user database 450, and the fitting server 500 may acquire the hearing information from the user database 450.

The fitting server 500 generates a fitting parameter by using the received hearing information (S540). Since the method of generating the fitting parameter has been described with reference to FIG. 4, duplicate description thereof will be omitted.

The fitting server 500 generates a fitting parameter and then transmits the fitting parameter to the portable terminal 200 through the mobile communication company server 700 (S550). Here, the fitting server 500 and the mobile carrier server 700 transmits the fitting parameters using the telephone number of the user's portable terminal 200 stored in the user database 450. In addition, the user may access the mobile communication company server through the portable terminal 200 and download the fitting parameters (S560). When the fitting parameter is stored in the portable terminal 200, the hearing aid program to which the fitting parameter is applied in the hearing aid mode is executed through the portable terminal 200 (S570).

As described above, according to the first embodiment of the present invention, the user connects the portable terminal 200 to the user terminal 300 and downloads the fitting parameters. The fitting parameter may be directly transmitted from the fitting server 500 to the portable terminal 200 without having to connect the portable terminal 200 to the 300.

Meanwhile, in the exemplary embodiment of the present invention, the fitting server 500 transmits the fitting parameter to the portable terminal 200 in which the hearing aid program is installed, but the fitting server 500 transmits the hearing aid program to which the fitting parameter is applied. 200). For example, when the hearing aid program is downloaded through the portable terminal 200 in which the hearing aid program is not installed, the fitting server 500 may transmit the hearing aid program to which the user-specific fitting parameter is applied to the portable terminal 200.

As described above, when the hearing information of the user is input to the user terminal, the fitting parameter may be transmitted to the portable terminal from the fitting server, and thus the user may use the optimized hearing aid program. In addition, since the ear microphone using the battery of the portable terminal is used, the ear microphone can be used without replacing the battery.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible.
