摘要
回顾了目前非线性失真客观测量方法,及其不能够充分反映电声系统非线性失真特性的原因,并介绍了国内外非线性失真主客观音质评价的最新科研成果,指出利用多频声评价非线性失真将是一个较好的选择。
The present objective measuring methods for nonlinear distortion and the reasons why they cannot sufficiently reflect the characteristics of electro-acoustical system＇s nonlinearity are analysed. The latest scientific researches of nonlinear distortion about subjective and objective sound quality evaluation around the world are introduced. It is pointed out thai muhitone will be a good choice to evaluate nonlinear distortion.
