Acoustics - Determination of sound power levels of noise sources using sound intensity - Part 1: Measurements at discrete points (ISO 9614-1:1993)

1.1 This part of ISO 9614 specifies a method for measuring the component of sound intensity normal to a measurement surface which is chosen so as to enclose the noise source(s) of which the sound power level is to be determined. The one-octave, one-third-octave or band-limited weighted sound power level is calculated from the measured values. The method is applicable to any source for which a physically stationary measurement surface can be defined, and on which the noise generated by the source is stationary in time (as defined in 3.13). The source is defined by the choice of measurement surface. The method is applicable in situ, or in special purpose test environments.  1.2 This part of ISO 9614 is applicable to sources situated in any environment which is neither so variable in time as to reduce the accuracy of the measurement of sound intensity to an unacceptable degree, nor subjects the intensity measurement probe to gas flows of unacceptable speed or unsteadiness (see 5.3 and 5.4).  In some cases, it will be found that the test conditions are too adverse to allow the requirements of this part of ISO 9614 to be met. In particular, extraneous noise levels may vary to an excessive degree during the test. In such cases, the method given in this part of ISO 9614 is not suitable for the determination of the sound power level of the source.  Note: Other methods, e.g. determination of sound power levels from surface vibration levels as described in ISO/TR 7849, may be more suitable.  1.3 This part of ISO 9614 specifies certain ancillary procedures, described in Annex B, to be followed in conjunction with the sound power determination. The results are used to indicate the quality of the determination, and hence the grade of accuracy. If the indicated quality of the determination does not meet the requirements of this part of ISO 9614, the test procedure should be modified in the manner indicated.

Akustik - Bestimmung der Schalleistungspegel von Schallquellen aus Schallintensitätsmessungen - Teil 1: Messungen an diskreten Punkten (ISO 9614-1:1993)

Dieser Teil von ISO 9614 legt ein Verfahren fest zur Messung der zu einer Meßfläche normalen Komponente der Schallintensität; die Meßfläche ist so gewählt, daß sie die Schallquelle(n), deren Schalleistungspegel bestimmt werden soll, einschließt. Der Oktav-, Terz- oder bandbegrenzte bewertete Schalleistungspegel wird aus den gemessenen Werten berechnet. Das Verfahren ist auf jede Quelle anwendbar, für die eine räumlich stationäre Meßfläche definiert werden kann und auf welcher der durch die Quelle verursachte Schall zeitlich stationär ist (wie in 3.13 definiert).
