Abstract
In the paper author have described the visualization methods in acoustic flow fields and showed how these methods may assist scientists to gain understanding of complex acoustic energy flow in real-life field. A graphical method will be presented to determine the real acoustic wave distribution in 3D flow field. Visualization of research results are shown in the form of a intensity streamlines in space and as a shape of floating acoustic wave and intensity isosurface in three-dimensional space, which is unavailable by conventional acoustics metrology. In traditional acoustic metrology, the analysis of acoustic fields concerns only the distribution of pressure levels (scalar variable), however in a real acoustic field both scalar (acoustic pressure) and vector (the acoustic particle velocity) effects are closely related.
Based on the research with intensity technique and using selected visualizations methods, many examples of vector space distribution of the real acoustic field are demonstrated. The application of the SI measurement for practical problems at the acoustical diagnostic and noise abatement are illustrated. The measurement technique described, as well as the method of graphical presentation of results, can enrich the knowledge of the mechanism of acoustic energy flux.
