摘要

基于心理声学的基本理论

在现场测试变频压缩机噪声的基础上

综合考虑响度、尖锐度指标

提出了心理声学烦躁度的经验公式.采用成对比较法进行主观评价

对实验结果作了线性相关性分析

并得到压缩机声品质主观评价值的预估模型.研究结果表明:采用烦躁度刻画声品质要比A声级更灵敏

心理声学烦躁度与主观评价的相关性较好

可达到0.917 3

但采用A声级则较差

只有0.711 9.因此

将烦躁度作为变频压缩机声品质评价的综合性能指标

能够比A声级更好地反映压缩机在不同工况下的噪声对人的实际影响.

Abstract

A-weighted sound pressure level does not fully satisfy the requirements of sound quality evaluation of electro-mechanical products. According to the noise analysis of frequency conversion compressor

an experiential formula of psychoacoustics annoyance is established considering loudness and sharpness synthetically

a pair-wise comparison method is proposed for subjective evaluation

and a pre-estimated model of sound quality subjective evaluation is obtained based on the linear correlation analysis. The research results indicate that the annoyance is more sensitive than dB(A)in sound quality evaluation

the correlation between psychoacoustics annoyance and subjective evaluation approaches to 0.917 3

exceeding remarkably 0.711 9 of dB(A). The psychoacoustics annoyance is reasonable to serve as a comprehensive index of sound quality evaluation for reflecting the real influence of noiseon a person.
