Abstract
A hearing aid system includes a first hearing aid configured to communicate with a second hearing aid, wherein the first hearing aid comprises a microphone and an A/D converter for provision of a digital input signal in response to sound signals received at the microphone, a processor that is configured to process the digital input signal in accordance with a signal processing algorithm into a processed digital output signal, the processor including a compressor, a D/A converter and an output transducer for conversion of the processed digital output signal to an acoustic output signal, and a transceiver for data communication with the second hearing aid, wherein, a gain of the compressor of the first hearing aid is controlled by a first compressor control signal with a value that is substantially equal to a value of a second compressor control signal controlling a gain of a compressor in the second hearing aid, whereby a sense of direction is maintained.
