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.
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。
The advantages of this system are fully exploiting the result of the encoder,taking account of the characteristic of human hearing system,which is the result of psychoacoustics research.
充分考虑到了人耳的听觉特性,利用编码器的计算结果和心理声学的研究成果,对从压缩音频中提取参数的含义做了透彻的分析,并通过实验检验了方法的有效性,从而在理论和实践两方面验证了方法的正确性和可行性。
