Abstract:
1. A hearing aid comprising: a first microphone for converting sound into a first audio signal; a second microphone for converting sound into a second audio signal; directional processing means for combining the first and the second audio signal to form a spatial signal; means for boosting low frequencies of the spatial signal in order to produce an equalized spatial signal; means for estimating a feedback path and for generating a feedback compensation signal; means for combining the feedback compensation signal with the equalized spatial signal in order to form a feedback compensated and equalized spatial signal, hearing aid processing means for processing the feedback compensated and equalized spatial signal to form a hearing loss compensation signal, an output transducer for converting the hearing loss compensation signal into an acoustic output, and an adaptive directional controller for controlling said directional processing means to provide adaptation of the spatial signal.
