The OROS Sound Intensity software module is designed for real-time measurement, visualization, and analysis of sound intensity and sound power. It enables engineers and researchers to localize noise sources and determine sound power levels by measuring sound intensity over one or more surfaces surrounding the test object. The software supports both discrete point and scanning measurement methods, fully compliant with ISO 9614-1 and ISO 9614-2 standards. It provides real-time display of sound pressure and intensity spectra (octave, third-octave, and FFT), 3D visualization of pressure and intensity fields, and automated calculation of quality indicators such as temporal variability, pressure-intensity, negative partial power, and non-uniformity. The module is suitable for use in laboratories, noisy environments, and field conditions, and is applicable to a wide range of industries including automotive, aerospace, energy, and manufacturing. It integrates with OROS analyzers and the NVGate platform, offering a user-friendly interface and powerful analysis tools for noise mapping, source identification, and sound power reporting.
