Abstract
An external microphone array is configured to be used with a hearing aid and comprises a number of microphones configured to detect one or more sound signals from a sound source and means for wirelessly sending the detected sound signal to at least one hearing aid. The external microphone array comprises means for automatically determining the direction of the sound source either by: a) receiving a wireless signal transmitted from a remote control; b) by receiving acoustic signals picked up by the hearing aid(s) and by further comparing the signals with signals received by the external microphone array. The external microphone array may e.g. take the form of a sphere, a hemi-sphere or a neckband.
