ISO 1996-2:2007 PDF

Scope: This part of ISO 1996 describes how sound pressure levels can be determined by direct measurement, by extrapolation of measurement results by means of calculation, or exclusively by calculation, intended as a basis for assessing environmental noise. Recommendations are given regarding preferable conditions for measurement or calculation to be applied in cases where other regulations do not apply. This part of ISO 1996 can be used to measure with any frequency weighting or in any frequency band. Guidance is given to evaluate the uncertainty of the result of a noise assessment. NOTE 1 As this part of ISO 1996 deals with measurements under actual operating conditions, there is no relationship between this part of ISO 1996 and other ISO standards specifying emission measurements under specified operating conditions. NOTE 2 For the sake of generality, the frequency and time weighting subscripts have been omitted throughout this part of ISO 1996.
