How sound meters work and how to classify
Noise meter - influencing factors:
1. From the perspective of the measurement object, it can be divided into the measurement of environmental noise (sound field) characteristics and the measurement of sound source characteristics.
2. From the time characteristics of the sound source or sound field, it can be divided into steady-state noise measurement and non-stationary noise measurement. Non steady state noise can be further divided into periodic variation noise, irregular variation noise, and pulse sound.
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, which not only specify the methods of noise measurement, but also specify the technical requirements for using sound level meters. We can use these standards to better select suitable sound level meters.
