Abstract

There is proposed a hearing device with a behind-the-ear microphone arrangement (1) not to be placed in the ear canal (5) whereat beamforming (9) provides for substantially constant amplification independent of direction of arrival of an acoustical signal at a predetermined frequency (10) and provides above such frequency directivity so as to reestablish a head-related-transfer-function of the individual.
