The scope of application of the noise meter
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, traffic roads, airports, audio, homes, farms and other places.
The noise meter is suitable for noise monitoring of household appliances, home audio and video sound testing, environmental noise in residential quarters, college laboratories, noise testing of enterprise workshops, and noise monitoring in urban environmental protection and other fields.
With the development of modern industry, environmental pollution is also produced. Noise pollution is a kind of environmental pollution, which has become a great harm to human beings. Traffic noise, construction noise, industrial noise, etc. affect people's normal study, life and rest. Although the noise from household appliances, audio equipment, etc. is not high, it is closely related to people's daily life, so people can't get quiet when they are resting, which is particularly annoying and can easily cause neighborhood disputes.
The standards of various countries and regions are not completely consistent. The International Organization for Standardization (ISO) stipulated in the allowable standard of environmental noise in 1971 that the allowable sound level of indoor ambient noise in residential areas is 35~45dB.
