Acoustic Camera - analoge microphone arrays

analog microphone array for acoustic camera

Analog microphone arrays are common used for applications which need very high samplerates e.g. wind power plants and ultrasonic measurements. If the hardware or sensors are already at hand the acoustic camera can be cost effectively built by buying only the software and an array.

There are a lot of applications e.g. wind tunnel, leakage detection and squeak, buzz and rattle localization.

The Noise Inspector software is the standard solution for visualizing sound sources. The application-oriented software guides you from data acquistion to analysis to saving and reporting of acoustic data.

  • Online- and offline analysis
  • Acoustic-photo und acoustic-video
  • A lot of HD algorithms: Beamforming, EVOB, CLEAN SC, MUSIC, Capon, DAMAS, Real 3D Beamforming,...
  • Frequency analysis and time-frequency analysis (sonogram)
  • Acoustic weighting (A, B, C) or linear presentation
  • Open interface to Matlab for own algorithms
  • Easy export of terce/octave, measurement, acoustic-photo and acoustic-video
  • Playback of local sound

The system can be expanded through the following things:

  • Additional channels and microphones
  • Additional arrays
  • Set-up to a 3D Array for 3D Beamforming
  • New array geometry for open up new fields of application
  • The Sound & Vibration Software offers new data acquisition an analysis functions
