1. A hearing aid comprising a first microphone, a second microphone, a calculation unit, a first and a second combiner, a low-latency filter and an electrical-acoustical output receiver, wherein the hearing aid is configured to:
provide a first directional signal by combining a first and a second microphone signal provided from the first and the second microphones respectively;
provide a second directional signal that is different from the first directional signal by combining a third and a fourth microphone signal provided from the first and the second microphones respectively;
use the calculation unit to provide an intermediate beamformed signal by linearly combining, in the first combiner, said first and second directional signals using a first adaptive parameter to provide a relative weighting of said first and second directional signals;
use at least one of said first and second microphone signals to provide an intermediate omni-directional signal;
use the calculation unit to provide a resulting beamformed signal by linearly combining, in the second combiner, said intermediate beamformed signal and said intermediate omni-directional signal using a second adaptive parameter to provide a relative weighting of said intermediate beamformed signal and said intermediate omni-directional signal;
use the calculation unit 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 calculation unit to determine a resulting hearing aid gain to be applied to the resulting beamformed signal based on the target gain and based on the values of the adaptive parameters;
use the calculation unit to synthesize the low-latency filter to apply said resulting hearing aid gain to said resulting beamformed signal in order to provide a hearing aid output signal as input to the electrical-acoustical output receiver.
