ABSTRACT:
In a hearing aid, as well as in a method for the operation of a hearing aid having a microphone system in which different directional characteristics can be set, the tonal quality is improved, particularly in a quiet hearing environment, by the signal delay for at least one microphone signal being increased so as to increase the transfer function in the frequency response of the microphone system, thus also improving the signal-to-noise ratio, by decreasing the proportion of the microphone noise in the microphone output signal.
