Abstract
A method of binaural signal enhancement in a binaural hearing aid system, includes providing at least one microphone audio signal in response to sound, providing an estimate of one of a target signal and a noise signal based on the at least one microphone audio signal, phase shifting the estimate of one of the target signal and the noise signal, providing a phase shifted signal in which the phase shifted estimate of one of the target signal and the noise signal substantially substitutes the respective one of the target signal and the noise signal, transmitting a first signal representing the phase shifted signal towards a first eardrum of a user of the binaural hearing aid system, and transmitting a second signal representing the at least one microphone audio signal towards a second eardrum of the user. A system for performing the method is also described.
