Noise Compass Nor1297

  • Dominant Source Detection
  • Mark and Filter Out Sources Outside a Region of Interest
  • Calculate sound levels for the site
  • 8 MEMS microphones

  • Noise Compass can be used in conjunction with Nor1545 Noise Terminal - find out more

  • The three-dimensional Nor1297 Noise Compass significantly reduces time spent on judging if a noise source should be a part of the overall noise calculation or not, simply by defining which direction the noise is coming from.

     

     

    When used together with Norsonic’s sound level meters and NorCloud, the device provides a three-dimensional vector pointing at the sound source. The system may also operate off-line and collect the data on the instruments SD card for later analyse in NorReview.

     

    The Nor1297 uses an array of eight microphones to capture the three-dimensional direction of sound. The loudest (A-weighted) sound source will be detected. A difference of 3 dB required to obtain a stable result.  The Noise Compass data includes a quality indicator to help differentiate between high quality directional information and random incident sound fields. If two sources of same level are present, the quality indicator will indicate random incident sound.

     

     

    The Nor1297 requires a Nor1545 monitoring station with a Nor145 or a Nor150 as main instrumentation. The Noise  Compass fits neatly below any of the Norsonic Nor1216-1217 Outdoor microphones and is compatible with the mechanical fittings designed for these devices. The system is designed to be linked to NorCloud but may also operate off-line and  collect the data on the instruments SD card for later analysis in NorReview.
