Overview

Aihua AWA6218J Environmental Noise Monitoring System

Product Details

The AWA6218J environmental noise automatic monitoring system mainly consists of noise monitoring terminals (including outdoor microphone units, data acquisition and control units, and power supply parts), data transmission units, central servers (computers), environmental noise data management software, etc. The front-end adopts real-time signal analysis technology, which can perform real-time 1/3 octave band analysis on noise signals, monitor and analyze the characteristics of environmental noise, determine the source of noise, and achieve remote data telemetry, noise event monitoring, system automatic calibration through wireless or wired network transmission, ultimately forming a report. It can accurately measure and calculate the perceived noise level and effective perceived noise level of airport noise. The hardware and software of the system adopt a modular structure, and the main functions can be configured according to the needs of users. It can only provide noise statistical analysis function, optional real-time spectrum analysis function, and can also add meteorological module, traffic flow, display screen, and GPS global positioning module. The outdoor microphone unit has windproof, rainproof, and bird proof functions, a wide working temperature range, and is also equipped with heating dehumidification and electrostatic calibration devices. The outdoor microphone has applied for a patent with patent number 200620102531.2. The AWA6218J environmental noise automatic monitoring system is used for noise monitoring in urban functional areas, industrial enterprise boundary noise monitoring, traffic noise monitoring, airport noise monitoring, construction site boundary noise monitoring, social life noise monitoring, and other environmental noise research fields.
