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.
