Zusammenfassung:	This disclosure describes a ceiling tile microphone system that includes a plurality of microphones coupled together as a microphone array and used for beamforming processing, one or more separate processing devices that couple to the microphone array, where one or more separate processing devices further include beamforming, acoustic echo cancellation, and adaptive acoustic processing; a single ceiling tile with an outer surface on the front side of the ceiling tile where the outer surface is acoustically transparent, the microphone array combines with the ceiling tile as a single unit, the ceiling tile being mountable in a drop ceiling in place of a ceiling tile included in the drop ceiling; where the system is used in a drop ceiling mounting configuration; where the microphone array couples to the back side of the ceiling tile and all or part of the system is in the drop space of the drop ceiling.
