The present invention relates to a method performed by a hearing determination control unit (40) connected to a key input unit (10). The method comprises: a step (S10) of determining the degree of hearing loss by inputting a test result value (dB) with respect to 125 Hz of left and right hearing air conduction of a customer tested in a hearing testing room provided from the key input unit (10), a test result value (dB) with respect to 250 Hz of the left and right hearing air conduction, a test result value (dB) with respect to 500 Hz of the left and right hearing air conduction, a test result value (dB) with respect to 1 kHz of the left and right hearing air conduction, a test result value (dB) with respect to 2 kHz of the left and right hearing air conduction, a test result value (dB) with respect to 4 kHz of the left and right hearing air conduction, and a test result value (dB) with respect to 8 kHz of the left and right hearing air conduction one by one in an audiogram a step (S20) of determining the type of the hearing loss by inputting a test result value (dB) with respect to 500 Hz of left and right hearing bone conduction of the customer tested in the hearing testing room provided form the key input unit (10), a test result value (dB) with respect to 1 kHz of the left and right hearing bone conduction, a test result value (dB) with respect to 2 kHz of the left and right hearing bone conduction, and a test result value (dB) with respect to 4 kHz of the left and right hearing bone conduction one by one in the audiogram and a step (S30) of determining sound discernment of the customer tested in the hearing testing room provided from the key input unit (10) by a sound discernment recognition rate.COPYRIGHT KIPO 2017본 발명은, 키 입력부(10)에 접속된 청력 판별 제어부(40)가 수행하는 방법으로서,상기 키 입력부(10)로부터 제공되는 청력 검사실에서 검사한 고객의 좌우 청력기도의 125Hz에 대한 검사결과값(dB), 좌우 청력기도의 250Hz에 대한 검사결과값(dB), 좌우 청력기도의 500Hz에 대한 검사결과값(dB), 좌우 청력기도의 1kHz에 대한 검사결과값(dB), 좌우 청력기도의 2kHz에 대한 검사결과값(dB), 좌우 청력기도의 4kHz에 대한
