A method of operating a hearing aid system () based on processing two groups of interleaved frequency bands such that one of the two groups of frequency bands is attenuated with respect to the other and such that it alternates with time whether one or the other of the two groups are attenuated and a hearing aid system () for carrying out the method.

Hearing aid system and a method of operating a hearing aid system

In a method and hearing aid () for processing sound signals for hearing impaired persons by providing multi-band compression processing an input sound signal is filtered by a band split filter () into a number of frequency bands to obtain band split signals. A signal level for each of the band split signals is determined and the frequency bands are arranged into a number of groups. Based on the signal levels in each of the groups, a compressor input level for a number of band split compressors each associated to one of the frequency bands is calculated. A compressor gain for each band split compressor is determined based on the corresponding compressor input signal and the band split signals are amplified with the corresponding compressor gain and summed in a summing unit () to produce an output sound signal.
