HEARING APPARATUS AND METHOD FOR REDUCING AN INTERFERENCE NOISE FOR A HEARING APPARATUS
First Claim
Patent Images
1. A hearing apparatus, comprising:
- a first reduction unit for reducing stationary interference noises of an input signal;
a second reduction unit for reducing interference noises oriented spatially in respect of the hearing apparatus; and
a selection facility for selecting at least one of said first and second reduction units for an output signal to be formed from the input signal.

Abstract
A noise reduction is provided for a hearing apparatus, with which both stationary and also non-stationary interference noises can be attenuated in an input signal. An output signal is in this way to convey a quite sound impression. A signal processing is provided, which effects a noise reduction on the basis of two different methods. Provision is made on the one hand for a noise reduction for stationary interference noises and on the other hand for a noise reduction for spatially oriented interference noises. A selection facility selects between the two noise reductions.

8. A method for reducing an interference noise for a hearing apparatus, which comprises the steps of:
-
analyzing an input signal; performing one of; selecting between a noise reduction for stationary interference noises and a noise reduction for spatially oriented interference noises in dependence on a result of the analyzing; and combining the noise reduction for stationary interference noises and the noise reduction for spatially oriented interference noises in dependence on the result of the analyzing; and generating an output signal from the input signal by means of one of the noise reduction selected and the combined noise reductions. - View Dependent Claims (9, 10)
