Product Introduction

The Noise Online Monitor is an all-weather outdoor automatic noise monitoring terminal. It is a fully functional monitoring device that complies with the GB3096-2008 "Environmental Quality Standard for Noise" and enables continuous automatic monitoring of different acoustic environments and key noise control areas. It automatically collects data without supervision and transmits it via 4G networks. Paired with the noise monitoring cloud platform, it facilitates refined grid-based management of noise pollution, enabling uninterrupted, round-the-clock supervision of noise emissions across various urban areas. It provides data support for achieving quiet cities and managing noise pollution.
