Patent ID: 8189837

Claim:
Hearing system ( 1 ) comprising a filtering unit ( 6 ) for improving a signal-to-noise ratio of an S+N-audio signal (S+N) composed of a desired audio signal (S) and a unwanted audio signal (N), which filtering unit ( 6 ) comprises an adaptive filter (F); an S+N-input for receiving said S+N-audio signal (S+N); an N*-input for receiving an N*-audio signal (N*), which is used as an estimate for said unwanted audio signal (N); and an S*-output for outputting an S*-audio signal (S*) obtained in dependence of said S+N-audio signal (S+N) and said N*-audio signal (N*), which is an approximation towards said desired signal (S); characterized in comprising a selecting unit ( 2 ) operationally connected to said filtering unit ( 6 ) for selecting a first input audio signal (In 1 ; In 2 ; . . . ) from at least two input audio signals (In 1 , In 2 , . . . ) and feeding said first input audio signal (In 1 ; In 2 ; . . . ) either to said S+N-input or to said N*-input.
