Abstract

In this study, In recent years, digital audio files have often been played in office space to improve efficiency, and the music played on the phone can interfere with the call, which also made it inconvenient to adjust the volume of each volume. Therefore, the purpose of this study is to provide volume synchronization control for each music to be played at a certain volume when multiple music is played to avoid such inconvenience, and automatic control by electrical signals when music is interrupted for telephone calls, announcements, etc. The methods of the study were major prior studies and literature studies, and were different from previous studies in that they provided a sound-synchronization control method that allows users to adjust the volume of audio files.

본 연구는 최근 사무공간에서 작업 능률 향상을 위해 디지털 오디오 파일을 재생시켜 두는 경우가 많은데, 전화통화를 하는 경우 재생되는 음악이 통화에 지장을 줄 수 있어, 이때에도 일일이 음량을 조절해야 하는 불편함이 있었다. 따라서, 본 연구에서는 이러한 불편함이 없도록 여러 음악을 재생할 때 곡이 바뀌더라도 일정한 음량으로 재생되도록 하는 음원별 음량 동기화 조절 장치를 제공함에 있고, 또한 전화통화, 안내 방송 등을 위해 음악 재생을 중단시키거나 출력 음량을 낮춰야하는 경우 전기적 신호에 의한 자동 제어가 이루어지도록 하는 음원별 음량 동기화 조절 장치를 제공함에 연구의 목적이 있다. 연구의 방법은 주요선행연구와 문헌조사를 하였으며, 종래의 디지털 오디오 기기가 오디오 파일들을 재생할 때 사용자가 일일이 음량을 조절해야 하는 불편함이 있었으나, 본 연구는 여러 음악을 재생할 때 곡이 바뀌더라도 일정한 음량으로 재생되도록 하는 음원별 음량 동기화 조절 장치 방법을 제공하고 있다는 점에서 선행연구와의 차별성을 두었다.
