Visualization blackboard-acoustic holography

The technique of acoustic holography is explained, using the example of a submerged, radiating, cylindrical object. The generalized near-field acoustical holography, Genah technique is described, focusing on its use of scientific visualization techniques. Incrementing the frequency of the visualized portion of the data set allows the frequency dependence of the acoustic pressure radiating from the cylinder. Incrementing the frequency of the visualized portion of the data set allows the frequency dependence of the acoustic pressure radiating from the cylinder to be observed. Additionally, the visible surfaces of the volume of pressure can be systematically enlarged, providing insight into the structure of the radiating pressure field for a given frequency.<
