I In Europe, a new “Machinery Direc- \ tive” has been written, coming into force from 1/1/ The purpose of this directive is to ensure the health of peo- ple using . ABSTRACT – Experimental testing was performed to investigate the validity of ISO Standard. for determining sound power levels of noise sources using . frequency noise sources using the intensity method. It is based on sound tests utilizing the sound intensity method as described in ISO (measurement at .

The faster, easier way to work with standards. In such cases, the method given in this part 961-41 is not suitable for the determination of thesound power level of the source. Measurement at discrete points.
Acoustics; determination of sound power levels of noise sources using sound intensity; part 1: Measurement at discrete points or by scanning Freely selectable segmentation and measurement sequence Field checking Steady-state checking Sound pressure, intensity and power spectra Spectra for sound power of the entire surface as well as partial sound pressure of the individual surfaces Calculation of the F1, F2, F3 and F4 field indicators as well as checking of the criteria according to ISO Color mapping of sound pressure, intensity and power spectra over all partial surface.
Sound power measurements in reverberation chambers or under free-field conditions are often infeasible for reasons of cost or due to the location of the sound source. Klik vervolgens op “Details” en selecteer de gewenste versie.

The method isapplicable in situ, or in special purpose test environments. The method isapplicable to any source for which a physically stationarymeasurement surface can be defined, and onwhich the noise generated by the source is stationaryin time as defined in 3.

The one-octave, one-thirdoctaveor band-limited weighted sound power level iscalculated from the measured values. The ISO standard defines two such methods, which allow satisfactory results to be obtained even under less favorable acoustic conditions e. Measurement by scanning ISO Search all products by.
