Abstract (en)

[origin: DE19629132A1] The invention concerns a method of reducing voice signal interference using a noise-reducing method. According to the invention, a masking curve is determined both for the input signal and the output signal of the noise reduction. By comparing the signal portions exceeding the respective masking curve, newly audible portions can be detected in the form of interference in the output signal, according to the type of musical tone, and subsequently damped selectively.
