초록

음질 평가는 좋은 소리를 만들기 위해 필수적인 요소이며, 음향의 특성과 대상 시스템에 따라 다양한 방법이 사용되고 있다. 본 논문에서는 음질 평가법의 전반적인 방법론 및 전송 처리된 음향 신호의 품질 평가법에 대해 ITU-T, ITU-R, IEC, 그리고 ANSI 등의 권고안에 기술된 국제 표준을 중심으로 요약하고 분석하였다. 분야별로는 음성 명료도, 음성 음질, 그리고 오디오 음질 평가법을 다루었으며, 현재 사용되는 권고안의 기술적인 내용과 최신 연구 동향 및 향후 발전 방향 등에 대해 기술하였다.

Assessing the quality of audio signals is an important consideration in making high quality sounds and various methods have been developed. This paper provides a general framework of sound quality and a technical overview of the international standard methods which are described in ITU-T, ITU-R, IEC and ANSI Recommendations in the speech intelligibility, speech quality, and audio quality areas. In addition, some recent findings and future works are included.
