| Resumen: | This Standard specifies methods of engineering grade of accuracy for determining the sound power level and 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 frequency-weighting A applied, is calculated using those measurements. |
