level at a given distance
Annex B (informative) - Recommendations for the location of the
reference sound source and the microphones, if only one
position is used for the reference sound source

levels and A-weighted sound energy levels from
octave-band levels
Annex E (informative) - Guidance on the development of
information on measurement uncertainty
Bibliography
Annex ZA (informative) - Relationship between this European
Standard and the Essential Requirements of EU Directive
2006/42/EC
Defines a method for determining the sound power level or sound energy level of a noise source by comparing measured sound pressure levels emitted by a noise source (machinery or equipment) mounted in situ in a reverberant environment, with those from a calibrated reference sound source.
