DIN/VDI Standards Committee Acoustics, Noise Control and Vibration Engineering


Acoustics - Noise emitted by machinery and equipment - Determination of emission sound pressure levels at a work station and at other specified positions from the sound power level - Amendment 1 (ISO 11203:1995/DAM 1:2018); German and English version EN ISO 11203:2009/prA1:2018


The document specifies two methods for determining the emission sound pressure levels of machinery and equipment, at a work station and at other specified positions nearby, by calculation from the sound power level. Emission sound pressure levels are determined with the same frequency weighting and time weighting, or in the same frequency bands, as those for which sound power levels have been determined.
