Abstract:
An input signal is provided with a low microphone noise in a hearing apparatus. The microphone noise in the input signal of the hearing apparatus is reduced, by the input signal being filtered by a Wiener filter, if a noise power determined at the input signal is smaller than a predetermined limit value. The Wiener filter is however deactivated, if the noise power is greater than the limit value or equal to the limit value.

Claim (Index 14):
A hearing apparatus, comprising:\n at least one microphone; and a facility for reducing inherent microphone noise generated independently of ambient noise and receiving signals from said at least one microphone, said facility for reducing said microphone noise having a Wiener filter and an estimation facility coupled to said Wiener filter for determining an estimated value for a noise power, wherein an input signal can be subjected to an attenuation by means of said Wiener filter for generating a processed input signal and a value of the attenuation can be determined on a basis of the estimated value for the noise power, said facility for reducing said microphone noise is set up to monitor the estimated value for the noise power and to deactivate said Wiener filter, if the estimated value is greater than a predetermined limit value.
