RULE 2: The sensor must be placed far enough away from the audience as not to pick up on individual conversations.
Placing the sensor too close to the source of ambient noise will cause the system to adjust primarily based on noise in one small location. In most
systems, the ambient noise that is being detected is due to crowds of people moving into and out of the zone. If a sensor is placed too close to the
crowd, it will pick up on individual conversations and the system will adjust based only on the isolated conversation. The sensor should be located
where it will pick up the cumulative level of all conversations in the space. Multiple X-ANS sensors can be assigned to a single zone to help prevent
over-reaction to a noise source in one specific part of the zone.
Note:
The X-ANS sensor is not a microphone and does not pick up audio and transmit it back to the system. It converts levels to data and passes
this level information back to the system. Therefore, there are no concerns that the system can violate any privacy.
RULE 3: Do not place a sensor at the edge of a zone where it will pick up sound from adjacent zones.
Placing the sensor too close to the edge of a zone can result in the level of the zone being adjusted based on program audio generated in the adjacent zone.
Since the ANC algorithm only analyzes audio from the zone where the sensor resides, audio created by the PA system in an adjacent zone could cause the
level of the parent zone to change. Placing the sensor in a centralized location within the zone will minimize the impact of audio from adjacent zones.
