OROS Sound Intensity Software
|
Sound intensity is the flow of acoustical power and its measurement allows visualization of radiation patterns. It has the advantage over sound pressure measurements because it can be measured in the Near Field and in the presence of background noise. In addition, Sound Power can be 
determined on several surfaces and several sources. Thus several suspected sources can be compared and ranked.
OROS Sound Intensity is a software option for the OROS 3-Series Analyzers. It automates the collection of sound intensity measurements and displays the results in a variety of formats. It can also be used to measure Sound Power and satisfies ISO 9614 standard.
Intensity, pressure, and reactivity spectra can be viewed in narrow band, 1/1 and 1/3 octaves formats. These results can then be visualized spatially in a 2D ("flattened box") or 3D map. The user can view the spectrum associated with a point by clicking on the point. Or the map of a particular frequency can be selected by choosing the frequency on the spectrum. Color, numerical, and isolevel contours are available.
Besides the sound intensity determination, the second major use of the OROS sound intensity is the sound power determination. B
oth ISO9614 part I and part II are covered. The user is guided through the standard procedure with the use of a comprehensive flowchart. During this procedure, the field indicators and criteria are checked by the software. Whenever one of them does not satisfy the standard, the software assists the user trough the successive measurements and improvements needed to meet the standards requirements. Then, a table gives a comprehensive insight of the field indicators computed for each of the surfaces included in the computations. The procedure is guided but a more flexible approach is also possible: it is always possible to set up the acquisition procedure as a sequence of actions or as a selectable access to the different measurement points.
