Acoustics - Determination of sound power levels of multisource industrial plants for evaluation of sound pressure levels in the environment - Engineering method (ISO 8297:1994)
The document specifies an engineering method for determining the sound power level of multi-source industrial plants which is relevant to the assessment of the noise they contribute to points in the environment around the plant. It is based in measuring the sound pressure level on a closed path (measurement contour) surrounding the plant and determining an appropriate measurement surface.
