ABSTRACT:
The present invention relates to a hearing aid with a compressor having a low and gain independent delay and low power consumption. The hearing aid comprises a multi-channel compressor for compensation of dynamic range loss and with a digital input for inputting a digital sound signal, and an output connected to an amplifier with a selectable gain as a function of frequency for compensation of frequency dependent hearing loss, and connected to an output for outputting the processed digital sound signal.
