Digital Ambient Noise Sensor PRA-ANS

Product Information

Specification

About:

• The PRA-ANS is an ambient noise sensor to monitor changing ambient noise levels for automatic adjustment of announcement or background music levels (AVC Automatic Volume Control).
• This ensures the public address audio is set at a configurable level
above the ambient noise in order to guarantee intelligibility of announcements, yet at a comfortable loudness.
