| 摘 要： | 文中以多频声作为测试信号,研究电声系统中感知倒谱距离与音质评价的关系。主观评价实验表明,采用多频声信号和听觉感知模型得出的感知倒谱距离能很好地反映频响曲线对音质的影响。当选取合适的评价节目源时,主客观评价结果的相关度均可达到0.84以上,最高可达到0.96。

| Abstract: | Relationship between perceptual cepstrum distance and sound quality evaluation of audio system is studied with multitone.Subjective validation experiment shows that the perceptual cepstrum distance can correctly reflect the influence of frequency response of the audio system on sound quality.When proper signal sources are used,the correlation coefficient between objective and subjective results all exceed 0.84,with the highest one being 0.964. |
