Machinery (MD) Directive (2006/42/EC)

  Last Official Journal reference

Thursday 2nd of April 2020

  Description:

Acoustics - Determination of sound power levels and sound energy levels of noise sources using sound pressure - Engineering methods for an essentially free field over a reflecting plane (ISO 3744:2010)

  Purpose

This International Standard specifies methods for determining the sound power level or sound energy level of a noise source from sound pressure levels measured on a surface enveloping the noise source (machinery or equipment) in an environment that approximates to an acoustic free field near one or more reflecting planes. The sound power level (or, in the case of noise bursts or transient noise emission, the sound energy level) produced by the noise source, in frequency bands or with A-weighting applied, is calculated using those measurements.

This standard superseed the "EN ISO 3744:2009"

Anyway is still possible use the "EN ISO 3744:2009" until April 30th, 2011
