摘要：

In this letter, a noise estimation method for spectral subtraction is proposed by using low-frequency regions of noisy speech. The method allows tracking the time variation of noise without complicated computation. The performance of a spectral subtraction method based on the new noise estimation is investigated, and its effectiveness is shown. in practical experiments.
