扬声器失真评价参数与主观音质评价参数的关系

本文探讨了扬声器的失真参数与主观音质评价参数的关系。其中可测量失真参数包括:前沿瞬态时间、后沿瞬态时间、谐波失真和频率响应。通过主观评价实验得到了不同音质评价术语的等级量表。在失真参数与声品质心理尺度的相关分析基础上,发现柔和度主要与前沿瞬态时间和谐波失真有关,清晰度与谐波失真有关,丰满度受到前沿瞬态时间的影响。

Correlation between the distortion parameters and perceived sound quality of loudspeakers

This work is to investigate relationship between subjective quality and objective distortion quantities for loudspeakers, for the aim of predicting perceived quality with physical parameters. The measured distortion parameters included: duration of initial transient, duration of final transient, harmonic distortion and frequency response. Subjective evaluation test was conducted to give the perceived sound quality described with six adjective words. Based on the correlation analysis between the distortion parameters and the sound quality psychological scales, it found that softness is mainly correlated with the duration of initial transient and the harmonic distortion. The clarity is correlated with the harmonic distortion; the fullness is influenced by the duration of initial transient.
