Abstract

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.

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.
