7.1 Sound Level Sensors Installation
The best location to put the Smart Sound Level Sensor is in the acoustic tile (Figure 64). Sensors
must be installed, if possible, in a central position to catch most of the noise in the zone.
The Sound Level Sensors should be installed at least 3 feet away from any ventilation air outlet.
The air coming out of the air outlet can cause turbulence on the sensor's membrane and distort the
measurements.
Figure 64: Example of the location and installation of a Sound Level Sensor
Drill a 3/8-inche hole through the tile to install the sensor. Insert the sensor through the tile and use
a second washer if necessary to keep the sensor in place.
