Abstract (en)

[origin: US2009257609A1] The invention specifies a method for noise reduction of an input signal of a hearing device. The cepstrum coefficients of the input signal, of the changed input signal and/or of at least one parameter obtained from the input signal are modified. The modified cepstral coefficients are used for formation of an output signal from the input signal. The output signal has reduced noise in relation to the input signal. With instationary noises in particular, an estimation is improved and an improved auditive quality is achieved for the hearing device.
