Scope

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.
