Description
Summary:The application of multiplanar near-field acoustic holography (NAH) to violins has produced an enormous amount of radiated sound-pressure and intensity data in three dimensions surrounding the instruments. The data have been analyzed to identify areas of significant sound energy radiation on the violin surface and the subsequent paths of that energy. The source regions have then been correlated to modal analysis results, as well as compared between structurally different violins. To complete such analyses has required powerful visualization tools. This presentation reviews the visualization software called application visualization system (AVS) and the techniques used for the investigation, including animating results on several sequential planes and viewing data as three-dimensional bricks that may be cut to view the interior behavior.
