Abstract (en)
[origin: EP1853089A2] The method involves determining a feedback-endangered frequency range. An input signal is received with a spectral portion in the frequency range. The known spectral portion of the input signal is reduced. The reduced spectral portion is mixed with a synthetic signal, in such a manner that in the spectral region, the efficiency of the entire signal corresponds to the efficiency before the reduction. The synthetic signal is produced by frequency shift from the input signal. A spectral envelope of the mixed signal is corrected with the help of linear predictive coding analysis. Independent claims are also included for the following: (1) a hearing device with feedback suppression device (2) a method for providing the spectral expansion in a hearing device.
