초록

본 논문은 스마트폰으로부터 디지털 보청기로 가청음 주파수 대역의 무선 통신을 수행한 내용을 다루었다. 반송주파수를 1 kHz 단일 채널을 사용하는 진폭편이방식에 의해 이진 데이터를 변조한 후, 정상적인 송수신 결과를 확인하였다. 전체적인 시스템 구현 과정을 상세히 설명하면서 실험 결과로 증빙해보였다. 스마트폰을 사용한 디지털 보청기 원격 제어가 가능한 실용화 제품을 실현하고자 한다.

In this paper, wireless communication from a smart phone to a hearing aid using audible frequency band sound was considered. 1kHz single channel carrier frequency was applied for amplitude shift keying (ASK) binary data modulation, and the result of the transmission and reception was tested. The overall system process was precisely explained and experimentally evaluated. The result will be applied for realizing a digital hearing aid with remote control feature by a smart phone.
