Digital Noise Sensing Microphones

The NSM digital noise sensing microphone provides the ability to continually track and monitor the surrounding ambient noise levels even during an announcement. This information is then used to automatically adjust paging announcements to ensure that they are broadcast at a predefined level above the ambient noise. This ensures announcements can be clearly understood over and above the environmental noise at any point in time. They are ideal for use in areas were the ambient noise levels are continually changing such as shopping malls, sporting venues, rail and bus stations etc. and its important to track the ambient noise levels to ensure clear and intelligible announcements.
