主观听音中的失真辨别能力训练

在扬声器的主观听音训练中,需要听音员对扬声器的非线性失真有较强的分辨能力；同时,也需要知道扬声器的何种失真更容易被人耳所察觉,针对容易被察觉的失真,对扬声器相应的结构、材料进行改善.因此,需要虚拟出各种特定的失真来进行主观听音.介绍了虚拟失真技术以及失真分辨训练的方法.

Audibility of Distortion in Subjective Listening Test

In the subjective listening test, the listener＇s audibility of the nonlinear distortion is important, and it is needed to know which distortion has more impact on the human audibility, then, the structure and material of speaker which cause this distortion are improved on. So several kinds of distortion for the subjective listening test are simulated. The technology of ＂Auralizing Distortion＂ and the method of audibility of distortion are introduced in this paper.
