Using microphone reinforcement in a large room
Microphone reinforcement
To improve speech intelligibility in a large room, the local
microphones are played out on speakers locally as well as being
sent to far end.
•
The room can be viewed as being divided in two zones. It
is assumed that there is a low acoustic coupling between
microphones in zone 1 and speakers in zone 2 and vice versa.
•
Microphones in zone 1 will be played out on all loudspeakers
in zone 2.
•
Microphones in both zones will be transmitted to far end.
•
The input signal from far end will be played out on
loudspeakers in both zones.
