Classification: CPC H | IPC H

Claim 0:
1. A hearing aid comprising a first microphone, a second microphone, a digital signal processor, a combiner, a minimum phase filter and an electrical-acoustical output receive, wherein the hearing aid is configured to:
provide a first signal by adding a first and a second microphone signal provided from the first and the second microphones respectively;
provide a second signal that is different from the first signal by combining a third and a fourth microphone signal provided from the first and the second microphones respectively;
use the digital signal processor to provide an intermediate beamformed signal by linearly combining, in the combiner, said first and second signals using an adaptive parameter to weight said first and second signals;
use the digital signal processor to determine a target gain adapted to provide at least one of: alleviating a hearing deficit of a user, suppressing noise and customizing the sound to at least one of a user preference and a sound environment;
use the digital signal processor to determine a resulting hearing aid gain to be applied to the intermediate beamformed signal based on the target gain and based on the value of the adaptive parameter;
use the digital signal processor to synthesize the minimum phase filter to apply said resulting hearing aid gain to said intermediate beamformed signal in order to provide a hearing aid output signal as input to the electrical-acoustical output receiver.
