Abstract:
The invention relates to a hearing aid comprising a first microphone configured to receive a first acoustic signal and to convert the first acoustic signal to a first electrical audio signal, a speaker configured to emit an acoustic output signal into an ear of a user of the hearing aid device, a first analog-to-digital converter for converting the first electrical audio signal into a first time-domain input signal, a first input unit comprising a first analysis filter bank which is configured to convert the first time-domain input signal to a number NI,1 of first input frequency bands wherein the number NI,1 of first input frequency bands is determined by said first analysis filter bank, a first frequency band bundling and allocation unit which is configured to bundle adjacent first input frequency bands and to allocate first frequency bands to be processed to a number NP,1 of first processing channels, a memory unit which is configured to store data indicating which of the first NI,1 input frequency bands are subject to a likelihood of feedback that is above a threshold, a signal processing unit is configured to process the first frequency bands to be processed in the number NP,1 of first processing channels, and wherein the number NP,1 of first processing channels is smaller than the number NI,1 of first input frequency bands, and wherein the first frequency band bundling and allocation unit is configured to generate a first bundling and allocation scheme which determines the bundling of the first NI,1 input frequency bands and the allocation of the first frequency bands to be processed to the first NP,1 processing channels wherein said first bundling and allocation scheme depends on the likelihood of feedback to occur in at least one of the first NI,1 input frequency bands.

Claim (Index 5):
A hearing aid device according to  claim 1 , comprising\n a second microphone configured to receive a second acoustic signal and to convert the second acoustic signal to a second electrical audio signal, a second analog-to-digital converter for converting the second electrical audio signal into a second time-domain input signal, a second input unit comprising a second analysis filter bank which is configured to convert the second time-domain input signal to a number N I,2  of second input frequency bands wherein the number N I,2  of second input frequency bands is determined by said second analysis filter bank, a second frequency band bundling and allocation unit which is configured to bundle adjacent second input frequency bands and to allocate second frequency bands to be processed to a number N P,2  of second processing channels, wherein the memory unit is configured to store data indicating which of the second N I,2  input frequency bands is subject to a likelihood of feedback that is above the predefined threshold, and wherein the signal processing unit is adapted to process the second input frequency bands in the number N P,2  of second processing channels, and where the number N P,2  of second processing channels is smaller than the number N I,2  of second input frequency bands, and wherein the second frequency band bundling and allocation unit is configured to generate a second bundling and allocation scheme which determines the bundling of the second N I,2  input frequency bands and the allocation of the second frequency bands to be processed to the second N P,2  processing channels based on the likelihood of feedback to occur in at least one of the second N I,2  input frequency bands.
