Descriptions : Acoustic holography of the stationary sources
Acoustic Scanner uses the technique of the acoustic holography (NAH) to identify sound sources and reconstructing 3-D sound fields by backward propagation of the pressures measured on a microphone antenna. The stationarity of sources makes it possible to use a scan microphone antenna and fixed-location-reference signals for data acquisition in a whole hologram plane. An enough number of references should be used for an industrial source comprising several independent sources (partially-coherent radiating pressure fields).
Sound fields (pressure, velocity, sound intensity, etc) are displayed in a plane of objects under being studied (projection plane). The representations can be scalar or vector plots. Acoustic Scanner provides users with the options of graphic representation in a raw frequency range, octave or one-third octave bands.
- Processing sound field produced by partially coherent sources (multi-references)
- Options for visualization such as sound pressure, velocity and sound intensity, etc.
- Entirely automatic processing (expert system, regularization)
- Open System allowing users to run theirs programs (User API)
- Options for graphics print out and data export in mat file
