The SmartSMS sound masking system is equipped with an adaptative adjustment system.
The ambient noise in a zone is measured and the masking sound level is adjusted based on this measurement.
The SMS-SEN Sound Level Sensor measures the ambient noise level in a zone. It is installed through a 3/8″ (9.5 mm) hole in acoustic tile. In the case of an open ceiling, it can be attached to the structrue.
Typically, one sensor covers 1,000 sq. ft. and up to 8 sensors can be installed in one zone.
