AMBIENT NOISE SENSOR W/POWER SUPPY & MIC

This Ambient Noise Sensor is designed to electronically adjust the level of a page announcement or background music in an area of a building where ambient noise levels are continuously changing. It ensures that page announcements or background music are intelligible even during periods of high ambient noise levels. The ANS501 monitors the ambient noise level through the use of an ANS500M sensor microphone module. Each sensor microphone module includes an adjustable mounting base for precise positioning. One microphone and one power supply are included.
