标准简介：This part of ISO 1996 defines the basic quantities to be used for the description of noise in community
environments and describes basic assessment procedures. It also specifies methods to assess environmental
noise and gives guidance on predicting the potential annoyance response of a community to long-term
exposure from various types of environmental noises. The sound sources can be separate or in various
combinations. Application of the method to predict annoyance response is limited to areas where people
reside and to related long-term land uses.
Community response to noise can vary differently among sound sources that are observed to have the same
acoustic levels. This part of ISO 1996 describes adjustments for sounds that have different characteristics.
The term “rating level” is used to describe physical sound predictions or measurements to which one or more
adjustments have been added. On the basis of these rating levels, the long-term community response can be
estimated.
The sounds are assessed either singly or in combination, allowing for consideration, when deemed necessary
by responsible authorities, of the special characteristics of their impulsiveness, tonality and low-frequency
content, and for the different characteristics of road traffic noise, other forms of transportation noise (such as
aircraft noise) and industrial noise.
This part of ISO 1996 does not specify limits for environmental noise.
NOTE 1 In acoustics, several different physical measures describing sound can have their level expressed in decibels
(e.g. sound pressure, maximum sound pressure, equivalent continuous sound pressure). The levels corresponding to
these physical measures normally will differ for the same sound. This often leads to confusion. Therefore, it is necessary
to specify the underlying physical quantity (e.g. sound pressure level, maximum sound pressure level, equivalent
continuous sound pressure level).
NOTE 2 In this part of ISO 1996, quantities are expressed as levels in decibels. However, some countries validly
express the underlying physical quantity, such as maximum sound pressure in pascals, or sound exposure in pascalsquared
seconds.
NOTE 3 ISO 1996-2 deals with the determination of sound pressure levels.
