488 - Sound power level estimation of a machine in presence of disturbing noise sources
De Sitter G., Guillaume P., Talal A.
Abstract
Nowadays, under the impuls of recent European directives, many industries try to lower the sound pressure level at their factory floors and/or the sound power level of their produced machines. In most practical cases the observed overall sound power level is a result of the superposition of several noise sources. Often, one is mainly interested to know the sound power level of each individual source. In other applications one is mainly interested to estimate the source power level of a specific machine while neighbouring machines or other major noise sources are still operating. In this contribution an adapted procedure will be proposed to estimate the sound power level of a machine in the presence of disturbing noise sources. To validate the new procedure, the obtained results will be compared with sound power level measurements performed in an anechoic room.
