Abstract (en)
[origin: US6687669B1] In a method for reducing interferences in a voice signal, a noise reduction method is applied to the voice signal, and spectral psychoacoustic masking is taken into account. A spectral masking curve is determined both for the input signal and the output signal of the noise reduction method. By comparing the signal portions exceeding the respective masking curve, newly-audible portions are detected in the form of interference in the output signal and subsequently damped selectively.
