声样本质量及其在声品质评价中的应用

Application of Sound Sample Quality to Sound Quality Evaluation

从声品质主观评价实验的要求出发,对声音样本库里不同存储格式的声样本质量进行了存储码、频谱等方面的研究,并应用Moore响度模型,计算比较Wav和Mp3格式声样本的响度、尖锐度和粗糙度,最终通过主观相似度比较实验,得出Wav格式和Mp3压缩格式声样本均能用于声品质主观评价实验的结论。

For subjective sound quality evaluation, a detailed analysis about binary codes and frequencies of sound samples in different formats when being storing is processed, and then loudness, sharpness and roughness of samples in terms of Way and Mp3 formats are calculated based on Moore＇s model. A subjective comparison of similarity shows that sound samples stored in Way and Mp3 can be applied in the subjective sound quality evaluation.
