Abstract
Microphone arrays with automatic beam focusing may easily focus on disturbing sound sources. In order to prevent this unwanted behavior, a predefined control sound signal is replayed from a direction of a disturbing sound source. The microphone array detects the predefined control sound signal, determines the direction of replay and in response performs a re-configuration according to the control sound signal. The reconfiguration may comprise eliminating the direction from its scanning range or cancel a previously made elimination of a different direction.
