RX392 Noise Monitoring System Noise Monitor

1. Introduction

Noise pollution is one of the four major pollutions in the contemporary world, which interferes with people's rest, study, and work. The main sources of urban noise are traffic, industrial production, construction, and social life, with construction and living noise being particularly severe. The proportion of complaints from regulatory authorities is increasing year by year. And the harm of noise to humans is multifaceted, mainly manifested as hearing loss, sleep disturbance, physiological and psychological effects on the human body. When people are100Working in a noisy environment around decibels can feel harsh, uncomfortable, and even cause temporary deafness.2021year12moon24At the 32nd meeting of the 13th session, the "Noise Pollution Prevention and Control Law of the People's Republic of China" (hereinafter referred to as the "Noise Law") was deliberated and passed2022year6moon5Effective from [date], provide strong laws for the control of noise pollution. The environmental department conducts automated noise monitoring in accordance with the law.

To meet the above needs, Beijing Clean Environment has borrowed mature atmospheric micro station technology and launched an automatic environmental noise monitoring instrument. The system consists of outdoor microphones, data acquisition and analysis units, data transmission units, and a big data aggregation center.

RX392 Noise Monitoring SystemThe equipment can perform 24/7 online monitoring of noise and weather, and can expand monitoring elements such as vehicle flow, video, particulate matter, and various gas concentrations, providing timely and accurate noise monitoring data and reliable data support for the monitoring and management of the acoustic environment. Mainly used for automatic monitoring of urban environmental noise, traffic noise monitoring, airport noise monitoring, noise event monitoring and reporting, as well as automatic collection, storage, and transmission of noise data.
