As the basic instrument of acoustic (noise) measurement, acoustic level meter, it is a kind of instrument which measures sound pressure level or sound level according to a certain frequency meter weight and time meter, and is the most basic and commonly used instrument in acoustic (noise) measurement. It is used for the measurement of the environment, machines, vehicles and other kinds of noise, as well as for electro-acoustic, architectural acoustics and other measurements. With the development of noise survey and prevention and environmental protection in China, as well as the control of noise index of products in related industries, the demand and application of acoustic scale meter are more and more extensive.
