- Scope
- This part of GB/T 3222 stipulates the method of determining the sound pressure level by direct measurement, by extrapolating the measurement results by calculation or by calculation, as the basis for evaluating environmental noise. This section recommends some better measurement or calculation conditions that have not been adopted by other specifications. This part of GB/T 3222 can be used for any frequency weighting or measurement in any frequency band, and gives guidelines for estimating the uncertainty of noise evaluation results.
