- Mobile Handheld Intensity Array

From

0

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.

  • <33 dB to 120 dB
  • recommend frequency range of the acoustic camera: from 40 Hz
