The EINS-1 Industrial Ambient Noise Sensor is a rugged device, designed to measure ambient noise levels in an open area such as railway platform, tunnels, oil platforms, etc. The powder coated aluminum housing with IP 65 grade is designed to withstand harsh weather conditions such as heat, cold, raining and wind and therefore making it suitable for outdoor deployments. ENS01 is a native IP device which connects to Exigo amplifiers via TCP/IP network and report ambient noise level continuously. There can be more than one EINS-1 per audio zone, while a minimum of one EINS-1 necessary per audio zone.
The EINS-1 can be mounted on a vertical wall, ceilings or on a pole.
The Automatic Volume Control (AVC) algorithm runs on Exigo amplifiers that uses one or more EINS-1 per audio zone to measure the ambient noise level and compensate speaker output gain by raising Sound Pressure level (SPL) with increasing ambient audio level. This will result in a consistent Signal-to-Noise ratio (SNR) and therefore making sure the audience hear the Public Address announcements loud and clear.
