(57) For reducing wind noise effects in a hearing instrument, a converted acoustic signal
is processed in a number of frequency bands, a low frequency band of which is chosen
to be a master band. A wind noise attenuation value is determined in each frequency
band, based on a signal level in the frequency band concerned and on a signal level
in the master band. A further wind noise reducing effect may be achieved in hearing
instruments with at least two microphones where in the presence of wind noise the
instrument may be switched from a direction al mode to a omnidirectional mode in which
an average of the output signals of the two microphones is used as signal. In single
microphone hearing instruments, the microphone signal and a delayed version of this
signal are used to improve wind noise detection and reduction.
