      Directive

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

      Last Official Journal reference

    Friday 8th of April 2011

      Description:

    Acoustics - Determination of sound power levels of noise sources using sound pressure - Engineering method in an essentially free field over a reflecting plane (ISO 3744:1994)

      Purpose

    This International Standard specifies a method for measuring the sound pressure levels on a measure- ment surface enveloping a noise source, under es- sentially free-field conditions near one or more reflecting planes, in order to calculate the sound power level produced by the noise source. It gives requirements for the test environment and instru- mentation, as well as techniques for obtaining the surface sound pressure level from which the sound power level of the source is calculated, leading to re- sults which have a grade 2 accuracy. It is important that specific noise test codes for vari- ous types of equipment be established and used in accordance with this International Standard. For each type of equipment, such noise test codes will give detailed requirements on mounting, loading and op- erating conditions for the equipment under test as well as a selection of the measurement surface and the microphone array as specified in this International Standard.
