Scope of application of noise meters
Noise meters, also called decibel meters and sound level meters, are commonly used as a noise measuring instrument.
Scope of application
Since the noise meter is mainly used for environmental noise, it is suitable for noise detection and noise census in factories, offices, transportation roads, airports, audio, family, farms and other places.
Noise meter can be applied to household appliances noise monitoring, family audio and video sound testing, residential neighborhood environmental noise, colleges and universities laboratories, enterprise plant noise testing and urban environmental protection and other areas of noise monitoring.
