Hearing aid with noise suppression and corresponding method for noise suppression

The hearing aid has a device (3) for estimating a useful signal from a noise-affected input signal and a first signal processing device (1) for processing the useful signal to form a useful output signal. The estimation device can also estimate a noise signal from the noisy input signal. A second si...

Beschreibung
Zusammenfassung:	The hearing aid has a device (3) for estimating a useful signal from a noise-affected input signal and a first signal processing device (1) for processing the useful signal to form a useful output signal. The estimation device can also estimate a noise signal from the noisy input signal. A second signal processing device (4) for simulating the transmission function of an acoustic path applies the function to the noise signal to form a noise output signal that is combined with the useful output signal. An independent claim is also included for a noise suppression method.
