I'll show you how to pick a good noise meter in a minute.
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.
