This part of ISO 1996 describes how sound pressure levels can be determined by direct measurement, byextrapolation of measurement results by means of calculation, or exclusively by calculation, intended as abasis for assessing environmental noise. Recommendations are given regarding preferable conditions formeasurement or calculation to be applied in cases where other regulations do not apply. This part of ISO 1996can be used to measure with any frequency weighting or in any frequency band. Guidance is given toevaluate 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 relationshipbetween this part of ISO 1996 and other ISO standards specifying emission measurements under specified operatingconditions.NOTE 2 For the sake of generality, the frequency and time weighting subscripts have been omitted throughout this partof ISO 1996.
