Abstract: The present invention relates to a microphone module comprising a first directional microphone comprising a front sound inlet and a front membrane, a second directional microphone comprising a rear sound inlet and a rear membrane, and a middle sound inlet arrangement being acoustically connected to the front and rear membranes, said middle sound inlet arrangement comprising acoustical resistance means arranged at least partly therein. The microphone module aims at generating a cardioid and an anti-cardioid response, or alternatively any other back-to-back polar patterns.

Abstract: The present invention relates to a microphone module comprising at least two directional microphones having different polar patterns and a single front sound inlet and a single rear sound inlet. The present invention provides a compact and space saving microphone module being less sensitive for mismatch or drift between the applied directional microphones and thereby very robust in directional performance. The microphone module of the present invention is, in particular, suitable in relation to hearing aid applications. The present invention further relates to an associated method for handling and processing signals from the at least two directional microphones.
