Claim:
1. A method for generating a transmission signal based on a useful signal disturbed by wind, and being transmitted from a hearing apparatus to a device external thereto, which comprises the steps of: generating a first and a second microphone signal from a wind-disturbed useful signal in the hearing apparatus; filtering the first and second microphone signals using a first filter system which has a first latency time, as a result first filter signals are obtained; determining parameters from the first filter signals, with which a contribution of the wind can be reduced from the first and second microphone signals; obtaining a wind-disturbed transmission signal from one of the first and second microphone signals or from the first and second microphone signals independently of the first filter signals; filtering the wind-disturbed transmission signal using a second filter system, which has a shorter latency time compared to the first filter system, as a result of which second filter signals are obtained as a basis for the wind-disturbed transmission signal or the transmission signal; and applying the parameters to the wind-disturbed transmission signal for reducing a contribution of the wind from the wind-disturbed transmission signal, so that the transmission signal is obtained.
