Sound Intensity

Product Announcement from OROS

Concerning Sound Power determination, the procedure recommended by international standard ISO 9614 can be followed step by step through a task dedicated interface that makes it rapidly operational. Thus, the Sound Intensity Solution is complementary to the Sound Power Solution that is based on the measurement of the sound pressure level as recommended by ISO 374x series.

Measuring sound intensity let the user be flexible on the measurement environment and on its acoustic constraints brought for example by background noise. In addition, Sound Power can be determined on several surfaces and several sources. Thus, several suspected sources can be compared and ranked.

Based on OROS portable analyzers, the Sound Intensity Solution is perfectly adapted for field measurements as often organized during machinery fault diagnosis and troubleshooting. Furthermore, the 3D or exploded 2D sound maps make of the Sound Intensity an efficient tool for locating sources as it is also of common practice in R&D laboratories when trying to reduce Sound emission from noise sources.

Main features are: Real time sound intensity spectrum Narrow band, octave, and 1/3 octave representation Guided acquisition procedure Sound power measurement: guided procedure following ISO9614-I&II Field criteria and indicators calculation Easy and flexible generation of complex and multiple surfaces Classical exploded 2D & advanced 3D graphics sound mapping Intensity, Pressure and Spectra selectable by segments Multi-frequency views Automatic sound power report Calibration module for phase calibration and pressure-residual intensity index.
