Product Specifications
This sound level sensor measures the ambient noise level in a zone.
The VoiceArrest sound masking system is equipped with an adaptive adjustment system. The ambient noise in a zone is measured, and the masking sound level is adjusted based on this measurement.
The VA-SEN sound level sensor measures the ambient noise level in a zone. It is installed through a 9.5 mm (3/8”) hole in an acoustic tile. In the case of an open ceiling, it can be fixed to the structure. Typically one sensor covers 1,000 sq. ft., and up to 8 sensors can be installed in one zone.
