Abstract:
1. A binaural hearing aid system comprising: a first hearing aid having a first channel; a second hearing aid having a second channel; a first peak detector in the first hearing aid for detecting an occurrence of a signal peak of a first channel input signal; a second peak detector in the second hearing aid for detecting an occurrence of a signal peak of a second channel input signal; a first gain adjustor in the first hearing aid, coupled to said first peak detector, for adjusting a first channel gain control signal based at least in part on the detected signal peak of the first channel input signal; a second gain adjustor in the second hearing aid, coupled to said second peak detector, for adjusting a second channel gain control signal based at least in part on the detected signal peak of the second channel input signal; a first channel compressing unit in the first hearing aid, said first channel compressing unit receiving the first channel input signal for generating a first channel dynamic range compressed output in accordance with the first channel gain control signal; and a second channel compressing unit in the second hearing aid, said second compressing unit receiving the second channel input signal for generating a second channel dynamic range compressed output in accordance with the second channel gain control signal; wherein the first channel dynamic range compressed output of the first channel compressing unit is for causing a cross-suppression effect in an output signal of the second channel, and the second channel dynamic range compressed output of the second channel compressing unit is for causing a cross-suppression effect in an output signal of the first channel.
