Scope

This part of GB/T 3222 specifies the basic parameters and evaluation methods for describing community environmental noise. It details the steps for evaluating environmental noise and provides guidelines for predicting the potential annoyance responses of people exposed to various environmental noises over the long term. The noise sources can be individual or a combination of multiple sound sources. The method of predicting annoyance responses is only applicable to areas where people live and to long-term land use scenarios.
People's responses to noise sources with the same sound level vary greatly. This part describes the correction for noises with different characteristics. The term "evaluated sound level" is used to describe the actual noise predicted or measured after one or more corrections have been applied. Based on the evaluated sound level, long-term annoyance responses can be estimated.
Noise signals are evaluated either individually or in combination. When necessary, the competent authorities may consider their pulsation, pitch, and low-frequency characteristics, as well as road traffic noise of different characteristics, other forms of traffic noise (such as aircraft noise), and industrial noise.
This part does not specify limit values for environmental noise.
Note 1: In acoustics, several different physical quantities used to describe sound (such as sound pressure, maximum sound pressure, and equivalent continuous sound pressure) are expressed in dB. The sound levels of these physical quantities for the same sound are often different, which often causes confusion. Therefore, it is necessary to specify the basic physical quantities (such as sound pressure level, maximum sound pressure level, and equivalent continuous sound pressure level).
Note 2: In this part, these physical quantities are expressed in dB units, but some countries also use other effective forms of expression, such as expressing maximum sound pressure in pasc
