1 minute to teach you how to choose and buy a high-quality noise meter
The noise meter is used for the sound level measurement of the environment, machinery, traffic, ships and other noises; the decibel meter and the classification of noise measurement mainly include the following types:
1. Noise meter can be divided into precision measurement, engineering measurement and noise census from the accuracy of measurement requirements.
2. The noise meter can be divided into steady-state noise measurement and unsteady-state noise measurement from the time characteristics of the sound source or sound field. Non-stationary noise can be divided into periodic noise, irregular noise and pulse sound.
3. The noise meter can be divided into broadband noise, narrowband noise and noise containing prominent pure tone components from the frequency characteristics of the sound source or sound field.
4. Noise meter can be divided into precision measurement, engineering measurement and noise census from the accuracy of measurement requirements.
