Acoustics — Description, measurement and assessment of environmental noise — Part 2: Determination of sound pressure levels


This document describes how sound pressure levels intended as a basis for assessing environmental
noise limits or comparison of scenarios in spatial studies can be determined. Determination can be
done by direct measurement and by extrapolation of measurement results by means of calculation.
This document is primarily intended to be used outdoors but some guidance is given for indoor
measurements as well. It is flexible and to a large extent, the user determines the measurement effort
and, accordingly, the measurement uncertainty, which is determined and reported in each case. Thus,
no limits for allowable maximum uncertainty are set up. Often, the measurement results are combined
with calculations to correct for reference operating or propagation conditions different from those
during the actual measurement. This document can be applied on all kinds of environmental noise
sources, such as road and rail traffic noise, aircraft noise and industrial noise.
