- Mobile Handheld Intensity Array



The mobile handheld intensity array is for the localization of low frequencies for stationary and transient noise from 40 Hz. Due to the small size and online analysis, it is a perfect trouble shooter. The detection is done by scanning the surface. The result is a photo or video (acoustic-photo/acoustic-video). Intensity measurements have a very high dynamic range because no algorithms or beampattern are limiting the range.
