Noise Controller

Description

Ambient noise controller for automatically matching the signal in case of ambient noise.
The wanted audio signal is held at a fixed distance to a second audio signal. The second audio signal is usually the ambient noise which normally appears in shopping centres hotels train stations airports or restaurants. The supplied noise detector and a microphone (available at option) monitor the ambient noise and the wanted signal (e.g. announcement or music) is boosted or attenuated accordingly. Thus the signal for announcements or music is at the set level always at a higher volume than the distracting ambient noise.
