Abstract:
1. A hearing aid comprising at least two microphone channels, a signal processor, and an output transducer, each of the microphone channels comprising a respective microphone, wherein the signal processor has adaptive matching means for matching the microphone channels, means for measuring a first transfer function of the first microphone channel, and for measuring a second transfer function of the second microphone channel, means for generating a model of each of the first and the second transfer functions, means for comparing a first set of differences between the first and second transfer functions to a second set of differences between the models of the first and second transfer functions in order to derive a set of matching parameters, and means for feeding the matching parameters to the adaptive matching means so as to enable the adaptive matching means to minimize the difference between the first set of differences and the second set of differences.
