摘要 本文首先从临界频带概念的提出、临界频带带宽的测评和临界频带率度量等几个方面详细分析阐述了临界频带这一听觉的十分重要的概念,然后以响度模型和音频压缩编码中的感知编码为实例,说明了临界频带在声频信号处理中的应用。 The introduction of the concept, the methods for determination of the critical bandwidth and the critical-band rate scale were discussed in details. The loudness model and the perceptual coder were explained as examples of the applications of the critical band in audio signal processing.
