Bogen ANS501 Ambient Noise Sensor Measurement System (Main Unit)

Main unit for the Ambient Noise Sensor system, can connect to up to four ANS500M microphone sensors (sensors are sold separately).

The Bogen Ambient Noise Sensor system is designed to monitor continuously changing ambient noise levels and electronically adjust the level of a page announcement and/or background music so intelligibility is maintained. The system consists of the control module (Model ANS501), a microphone module (ANS500M), and a power supply. The system ensures that page announcements and music are audible even during periods of high noise levels by continuously monitoring the ambient noise level through a microphone module located in the subject area and adjusting the paging signal level into the system’s amplifier.
