Abstract
A hearing aid includes a first microphone for providing a first audio input signal, a second microphone for providing a second audio input signal, a signal processor configured for generating a hearing loss compensated audio output signal based at least in part on the audio input signals, and a receiver for converting the audio output signal into an output sound signal, wherein the signal processor is configured to perform directional processing, based on the first and second audio input signals, in a first frequency range and substantially omni-directional processing in a second frequency range, at least a part of the first frequency range being higher than the second frequency range, and wherein a lower cutoff frequency of the first frequency range is adjustable.
