ISO 1996-2:2017 PDF Download

ISO 1996-2:2017 is a standard that specifies how to calculate sound pressure levels in order to analyze environmental noise or compare different scenarios in geographical research. The standard specifies two methods for estimating sound pressure levels: direct measurement and calculation-based extrapolation of measurement data. While the standard is primarily intended for outside measurements, it also provides some indoor measurement instructions.

The standard allows for measurement flexibility and allows the user to evaluate measurement uncertainty. There are no established boundaries for acceptable uncertainty levels, and it is the user's responsibility to assess and report measurement uncertainty for each case. Measured data are sometimes supplemented with calculations to account for reference operating or propagation circumstances that differ from those encountered during the actual measurement.

ISO 1996-2:2017 is applicable to a wide range of environmental noise sources, including road and rail traffic noise, airplane noise, and industrial noise. Its goal is to establish a consistent approach for estimating sound pressure levels in order to make ambient noise evaluation and comparison easier.
