Abstract
Disclosed embodiments include systems and methods of configuring, e.g., a hearing prosthesis comprising a beamforming microphone array having two or more microphones. Some embodiments include (i) storing a plurality of sets of beamformer coefficients in memory, where each set of beamformer coefficients corresponds to one of a plurality of zones on a recipient's head, and (ii) configuring the hearing prosthesis with a set of beamformer coefficients that corresponds to the zone on the recipient's head where the beamforming microphone array is located. Other embodiments include determining a set of beamformer coefficients based on magnitude and phase differences between microphones of the beamforming array, where the magnitude and phase differences are determined from a plurality of head related transfer function measurements for the microphones.
