Iso 9614-1

In some cases it will be found that the test conditions are too adverse to allow the requirements of ISO to be met. For example, extraneous noise levels can exceed the dynamic capability of the measuring instrument or can vary to an excessive degree during the test. In such cases the method given in ISO is not suitable for the determination of the sound power level of the source. Proof returned by secretariat 60 Publication Check out our FAQs. Buy this standard. This standard was last reviewed and confirmed in Therefore this version remains current.

Abstract Preview ISO specifies a method for measuring the component of sound intensity normal to a measurement surface which is chosen so as to enclose the sound source s of which the sound power level is to be determined. Allocation of the measurement area onto digital photographs of the whole sound source. Take the smart route to manage medical device compliance. Mesurages par points Title in German Akustik.

The one-octave, one-third-octave or band-limited weighted sound power level is calculated from the measured value.

The method is applicable in situ or in special purpose test environments 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.
