The Impact and Classification of Noise Meters
Noise meter - influencing factors:
1. From the measurement object, it can be divided into feature measurement of environmental noise (sound field) and measurement of sound source features.
2. From the time characteristics of the sound source or field, it can be divided into steady-state noise measurement and non-stationary noise measurement. Non steady state noise can also be divided into periodic variation noise, irregular variation noise, and pulse noise.
3. From the frequency characteristics of the sound source or field, it can be divided into broadband noise, narrowband noise, and noise containing prominent pure tone components.
4. From the perspective of measurement accuracy requirements, it can be divided into precision measurement, engineering measurement, and noise survey. For the sake of uniformity, both international and domestic standards for noise measurement have been established. These standards not only specify the methods for noise measurement, but also specify the technical requirements for the use of sound level meters. We can use these standards to better select suitable sound level meters.
