An experimental study of Sound Intensity distributions in real acoustic flow field
In the paper authors 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. The acoustic intensity measurement technique has been used for the visualization of this kind of sound field. The result of investigation shows the distribution of vector acoustic fields created by working loudspeaker as an acoustic intensity streamlines, propagating wave shapes and intensity iso-surface, and all enable a full interpretation of vector phenomena in a generated flow field. The visualization of real-live sound fields is useful for understanding the directional radiation of sound emitted by the loudspeakers into three-dimensional space. For that, the vector distribution field will be done using own program (SIWin) that are developed for the processing and the visualization investigated results including method of animation the flow wave.
