Noise detector is designed mainly in accordance with the national standard GB/T 3785.1-2010 "Electroacoustic Sound Level Meter Part 1: Specifications" and the international standard IEC 61672-1:2002 for Class 2 Class X sound level meters. It is mainly used for real-time measurement of various types of noise such as environmental noise, traffic noise, workplace noise, construction noise and social life noise. With this module, customers no longer need to worry about complex noise signal processing, they can focus on their areas of expertise and create value for customers more quickly.
