| Resumen: | The document specifies a method of accuracy grade 3 for measuring the sound pressure levels on a measurement surface enveloping the source and for calculating the sound power level produced by the source. It gives requirements for the test environment, the instrumentation and the microphone array. Das Dokument beschreibt ein Verfahren der Genauigkeitsklasse 3 zur Messung der Schalldruckpegel auf einer die Geräuschquelle einhüllenden Messfläche sowie zur Berechnung des von der Quelle erzeugten Schallleistungspegels. Es enthält Anforderungen bezüglich der Messumgebung, der Messausrüstung und der Mikrofonanordnung. |
