Abstract
A hearing aid includes: at least one microphone for provision of at least one microphone audio signal in response to sound received at the at least one microphone; a signal separation unit configured to provide an estimate of a target signal and an estimate of a masker signal based on the at least one microphone audio signal; a frequency modifying unit configured to modify a frequency content of at least one of the estimate of the target signal and the estimate of the masker signal, to thereby output the estimated target signal and the estimated masker signal substantially in different frequency bands; and a receiver for conversion of a combination of the estimate of the target signal and the estimate of the masker signal output by the frequency modifying unit into an acoustic signal for transmission towards an eardrum of a user of the hearing aid.
