Noise Meter Impact and Classification
Noise meter - influencing factors:
1. According to the measurement objects, it can be divided into measurement of characteristics of environmental noise (sound field) and measurement of sound source characteristics.
2. Based on the time characteristics of the sound source or sound field, it can be divided into steady-state noise measurement and unsteady-state noise measurement. Unsteady noise can be divided into periodic changing noise, irregular changing noise and impulse sound.
3. Based on the frequency characteristics of the sound source or sound field, it can be divided into broadband noise, narrowband noise and noise containing prominent pure tone components.
4. According to the accuracy of measurement requirements, it can be divided into precision measurement, engineering measurement and noise census, etc. For the sake of unification, some international and domestic standards for noise measurement have been formulated. These standards not only stipulate the methods of noise measurement, but also specify the technical requirements for the use of sound level meters. We can use these standards to better Choose the right sound level meter.
