NOISE INSPECTOR ACOUSTIC CAMERA SOLUTIONS


Introduces Noise Inspector, the best solution for acoustic cameras, developed by his partner CAE Software and Systems. Powerful and flexible, Noise Inspector offers an accurate, fast and smart technology for sound source localization. With great ease of system setting up, sound and vibration emissions becomes quickly visible in real-time. The software is easy to use for non-specialists and offers great functionality for professionals. The results are acoustic images or movies, easy to interpret for everybody, and easy to communicate. Noise Inspector is the perfect mobile tool to help you determine dominant sound sources in the Environment, improve your product quality, minimize development time and to save your resources. The system guarantees precise and uncomplicated determination of acoustic sources, also convinces through its really low costs.

All microphone arrays are designed with optimized microphones distribution, contributing to high resolution results with high dynamic range. Among the great choice of arrays, there is one to fit each need:Bionic Array XS (40 mics, 0.45m diameter)

  • Bionic Array XS (40 mics, 0.45m diameter)
  • Bionic Array S (40 mics, 0.6m diameter)
  • Bionic Array M (112 mics, 1m) NEW!
  • Bionic Array L (40 mics, 1.6m diameter)
  • Spider Array (40 mics, 0.8m*0.8m): expandable array size, expandable number of channels, changeable microphone positions

Each microphone array is combined with an embedded High Definition digital camera.


NEW! BIONIC M ARRAY

The new Bionic M microphone array has a diameter of 100 cm and consists of 112 microphones and a high speed digital camera.
It is engineered for use from 40 Hz with the holography method. The optimized microphone distribution guarantees perfect sound source localization and a high dynamic range.
The seven detachable microphone arms (setup about 1 minute, without cable) make the system very mobile (everything is integrated in the camera body) with a small package size.
Typical applications are wind power plants, gear, industrial facilities and environmental measurement.


HARDWARE

    Data from the array is managed by the highly innovative I²S digital-data frontend:
  • Compact and lightweight
  • Robust
  • Battery operable
  • Fanless
  • 24 bit resolution
  • Trigger and RPM channel
  • Expandable
  • Up to more than 1000 microphone channels capability.

For the Bionic XS and Bionic M arrays, the data frontend is integrated into the camera body.
The whole system is easily and quickly setup.


SOFTWARE

Many well-known algorithms are available, and complemented with unique new algorithms.

    For measurements in the far field:
  • Standard Beamforming, orthogonal Beamforming
  • Enhancements to beamforming for optimal resolution at low frequencies: Capon, DAMAS, MUSIC algorithms.
  • CleanSC, to get a dynamic range of more than 40 dB
  • Rotating Beamforming, for ventilators, turbines, fast rotating etc.. for analyzing wingtips and blade edges.
  • Further algorithms may be seamlessly integrated due to the open program structure and the easy-to-use labVIEW or Matlab interface
  • Worldwide unique 3D beamforming technology.

For measurements in the nearfield, and for low frequency noise sources as well: Nearfield Acoustic Holography (SONAH).
Acoustic processing is applicable to stationary and non-stationary noise sources.
