Acoustics -- Attenuation of sound during propagation outdoors -- Part 2: General method of calculation
This standard was last reviewed and confirmed in 2017. Therefore this version remains current.
Describes a method for calculating the attenuation of sound during propagation outdoors in order to predict the levels of environmental noise at a distance from a variety of sources. The method predicts the equivalent continuous A-weighted sound pressure level (as described in ISO 1996) under meteorological conditions.
