easy method and apparatus for providing a hearing test and hearing and calibration services are provided in accordance with the results . The method of the present invention comprises the steps of: on the basis of the response whether the frequency for detecting the first hearing test frequency bands After hearing the first output by increasing a frequency band of each of the volume on the basis of the response for that detecting whether or not a second hearing frequency band Second hearing loss in each frequency band by changing the frequency band of the output, and then on the basis of the response for that detecting whether the third hearing frequency band Storing a hearing loss is eliminated frequency band and relieve the requirements in the above step in hearing loss hearing loss compensation information And a step of outputting the audio signal after correction in accordance with the hearing loss compensation information and the device of the present invention is a frequency generator for generating a frequency for the test An audio output unit for outputting a test frequency A user interface for receiving a users response according to the output of the frequency for the test The control unit determines the hearing frequency band and for generating correction information for correcting the hearing frequency band After correcting the frequency generated by the frequency generator output to the audio output to the frequency corrector And a hearing loss compensation information storing / managing a correction information storage. Therefore, the present invention can self-diagnose early hearing loss, hearing loss can be eliminated easily when the invention is applied to a call or an audio listening using a smartphone.손쉽게 청력을 테스트하고 그 결과에 따른 난청 보정 서비스를 제공하는 방법 및 그 장치가 제공된다. 본 발명의 방법은 테스트용 주파수에 대한 응답 여부에 의거하여 제1 난청 주파수 대역들을 검출하는 단계 제1 난청 주파수 대역들 각각의 음량을 높여서 출력한 후 그에 대한 응답 여부에 의거하여 제2 난청 주파수 대역들을 검출하는 단계 제2 난청 주파수 대역들 각각의 주파수 대역을 변경시켜 출력한 후 그에 대한 응답 여부에 의거하여 제3 난청 주파수
