The invention relates to a hearing aid with a signal processing unit and at least two microphones which can be coupled together to form directional microphone systems of a different order, where microphone signals emitted by directional microphone systems of a different order can be coupled together in a weighting dependent on the frequency of the microphone signals. The invention further relates to a method for operating a hearing aid of this type.

Hearing aid device, comprising a directional microphone system and a method for operating a hearing aid device

In a method for operating a hearing aid or hearing aid system, and a hearing aid or hearing aid system, wind noises are detected by analyzing the output signals of at least two microphones. If wind noises are present, the signal processing unit of the hearing aid or hearing aid system and/or the signal paths of microphones are adapted in order to reduce such noises.

Method for operating a hearing aid or hearing aid system, and a hearing aid and hearing aid system

For level limitation of a time-discrete signal in a digital hearing aid having at least an input transducer, an A/D converter, a signal processing unit and an output transducer, the sampling rate of the time-discrete signal is boosted in the signal path following the A/D conversion and signal values of the time-discrete signal with a boosted sampling rate are limited to a maximum value. Harmonics that arise upon limitation of the signal values that are folded back into the audible frequency range are thus suppressed.
