OROS Sound Power DATASHEET Description A flexible test set up following the standards Sound power test on a mine excavator Sound Power measurements are based on a well-defined procedure described by international standards. Sound Power is calculated by integrating the Sound Pressure Level measured over a virtual surface surrounding the source. The Sound Pressure Level is measured at discrete microphone positions over this surface. The international standards define the test setup; the test environment, the measurement procedure, the type of instrumentation used and the way Sound Power should...

OROS Sound Power DATASHEET An accurate and efficient measurement The first step is the measurement of the background noise. The second step is the measurement of the source sound pressure. As an example, if a repeatability test was setup as required, the operator will be prompted and guided along a procedure including 3 runs to check the repeatability of the measurement. The third step is the results preview and report fill up for complementary information required by the standards (operator name, product reference etc…). The final step is the automatic report generation in a customized form....
