心理声学主要研究两种事物之间的关系：物理声音与人脑中对它们的解释。直到最近，心理声学的研究重心开始从认知过程的细节转向了对周边的听觉系统行为的研究。
这是一个精神物理学的分支学科，它侧重于研究感官的输入刺激和这些刺激所引发的心理反应或行为之间的关系。因为观察这些反应的过程中存在人与人之间的个体差异，所以通常需要用统计结果来证实某个观点。
一些传统的心理声学注重对音高、响度与音色的感觉。而当代心理声学的工作包含较高层次的概念，例如听觉感受、流，以及听觉场景分析。（引自：巴里•特鲁奥克斯《声学生态手册》，光盘版。剑桥大街出版社）
Psychoacoustics is the study of the relationship between physical sounds and the brain's interpretation of them. Until recently, psychoacoustics has devoted more attention to the behaviour of the peripheral auditory system than to the details of cognitive processing.
The discipline is a branch of psychophysics in that it is interested in the relation between sensory input stimuli and the behavioural or psychological response that they provoke. Because of individual variations in observed responses, statistical results are most often achieved.
Some of the traditional psychoacoustic concerns involve the perception of pitch, loudness, volume and timbre. Contemporary work involves higher level concepts such as auditory percepts, streaming, and auditory scene analysis. (Source: Barry Truax - Handbook for Acoustic Ecology CD-ROM Edition.
