Then human auditory masking is studied where its characteristic is combined with the multi-band spectralsubtractionmethod.
其次，本文研究了人耳听觉掩蔽特性，并将听觉掩蔽效应应用于多频带谱减的语音增强方法中。

This paper studies the speech enhancement technology, and proposes an improved spectralsubtractionmethod based on the auditory characteristics and the speech spectrum characteristics.
An improved non-linear spectralsubtraction algorithm is also put forward. The application range of the spectralsubtraction is expanded by the new noise estimation method.
