Outstanding performance

  • 3 array sizes with up to 384 microphones available
  • Real time virtual microphone
  • Digital microphones, no extra acquisition unit needed
  • Intuitive software
  • Plug and play within 5 minutes

The Norsonic Nor848A sets a new standard for acoustical cameras. The large number of microphones eliminates the problems of ghost-spots, compared to traditional acoustical cameras where the relatively low number of microphones increases the side lobe effect, resulting in the so called ghost-spot effect. You measure a non-existing source. The Nor848A software is extremely intuitive and easy to use. Just after a few minutes of training, the user is able to operate the system and do real measurements. Three camera frontends are available.

A 0.4m array with 128 microphones, a 1 meter array holding 256 microphones and a 1.6 meter array with 384 microphones! The system enables the user to perform noise analysis with a clear view of the spatial distribution of the sound in real time! The system is easy to set up in the field. Just power the self-contained unit from mains or battery and connect the LAN cable to the computer. The system is ready to measure in just a few minutes after entering the site.

Features

  • Robust camera front-end based on a circular carbon fiber disc, three sizes available:
    • 128 microphones 0.4 meter array
    • 256 microphones 1 meter array, only 11 kg weight
