◉ Introduction to Noise Testing
Noise is the sound that interferes with the surrounding living environment.
Noise monitoring is the process of monitoring the noise and its sound sources that interfere with people's normal life, work and study, and determining whether it exceeds the emission limit specified by the national standard.
◉ Scope of Test
(1) Environmental noise monitoring such as social life noise, industrial enterprise boundary noise, building construction boundary noise, road traffic noise, railway boundary noise, urban rail transit station platform noise, and secondary radiation noise.
(2) Routine monitoring of urban acoustic environment
◉ Test Items
Noise from social life: noise generated by commercial cultural and entertainment venues, equipment and facilities used in commercial business activities;
Road traffic noise: the noise generated by the operation of motor vehicles on roads with certain technical conditions and facilities;
Railway boundary noise: the noise generated by the operation of rolling stock, 30m away from the centerline of the outer track of the railway;
Secondary radiation noise: indoor secondary radiation noise generated by the vibration of buildings along the line caused by the operation of urban rail transit trains;
Boundary noise of industrial enterprises: noise generated by the use of fixed equipment and facilities in industrial production activities and measured and controlled at the factory boundary;
Boundary noise of building construction: noise generated in the process of building construction, measured and controlled at the boundary of the building;
Urban rail transit station platform noise: the platform noise of subway cars and light rail stations when trains enter and exit the station;
Routine monitoring/routine monitoring of urban acoustic environment: including regional acoustic environment monitoring, road traffic acoustic environment monitoring, and functional area acoustic environment monitoring.
