九线拉王怎么能赢钱the smartsms 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.
九线拉王怎么能赢钱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, the noise level measurement meter can be attached to the structure.
typically, one noise level measurement meter covers 1,000 sq. ft. and up to 8 sensors can be installed in one zone.
