초록

본 논문에서는 방송법 개정 및 디지털 텔레비전 방송 음량 기술 기준 시행에 따라 주요 방송 채널들을 대상으로 시행 전후의 방송음량 변화를 측정하고 분석하였다. 분석 결과 시행 전에는 측정 대상인 모든 방송 채널들이 기술기준보다 높은 음량 레벨로 방송을 하였으나, 시행 후에는 측정한 방송 채널 프로그램들의 대부분이 기술기준에서 제시하는 음량 레벨을 유지하여 기술기준에 적합했으며, 음량의 표준편차 역시 낮아진 것을 알 수 있었다. 그러나 일부 프로그램들은 기술기준에 부적합하여 이의 시정이 요구되며, 측정 방법의 개선을 위한 추가 연구의 필요성도 제시되었다.

In this paper, the changes of broadcasting loudness before and after are measured for the major broadcasting channels according to the amendment of broadcasting law and enforcement of digital television broadcasting loudness technology standards. Before the implementation of digital television broadcasting loudness technology standards. all the channels to be measured were broadcast at a higher volume level than the technical standards. However, after the implementation, most of the channels to be measured were maintained at a loudness level suitable for the technical standards. However, some programs are inadequate to meet technical standards, requiring corrective action, and the need for additional research to improve the measurement method.
