响度是反映人耳对声音强弱感知的最基本参量,它是分析计算很多其它心理声学参量的基础.响度特征的研究不仅在噪声评价、心理学及声品质方面有重要的应用,还广泛应用于语音信号处理等方面.在此从等响曲线、双耳异响条件下的响度感知特征以及纯音和复音时变信号响度感知特征等三个方面介绍了近年来的研究结果.

Loudness is an important metric describing aural perception to sound intensity, and it is also the essential quantity from which many other psychoacoustic metrics derived. The study of loudness perception has important practical meaning in noise evaluation, psychoacoustics and sound quality research, and in speech signal processing as well. Recent research works on equal loudness level contours, overall perceived loudness in dichotic hearing condition and loudness of time varying pure / complex tones are reviewed and discussed.
