Abstract:
1. A system for improving the acoustical communication between interlocutors in a room comprising: a first microphone located in the vicinity of a first interlocutor in the room for generating a first sensed signal adjacent to the first interlocutor; a second microphone located in the vicinity of a second interlocutor in the room for generating a second sensed signal adjacent to the second interlocutor; at least one loudspeaker located in the room for converting electrical signals into acoustical output signals; and a signal processing unit that receives and processes the first and second sensed signals, and provides processed microphone signals to the at least one loudspeaker; where the processed microphone signals are each time delayed by the signal processing unit such that the acoustical output signal arriving at the first interlocutor is perceived by the first interlocutor to originate from the direction of the second interlocutor.
