ABSTRACT:
The wind sensitivity of hearing aids is reduced. The noise level of at least two microphones is measured and to compared with one another. The microphones are controlled according to the comparison result. In one embodiment, the microphone having the lowest noise level is used as an omnidirectional microphone in a wind situation.
