- In this article, the author described methods of visualizing the acoustic flow and showed how these methods can help scientists understand the complex flow of acoustic energy in a real field. A graphical method for determining the distribution of acoustic waves in a real 3D flow field will be presented. Vector imaging of acoustic events is not possible with the use of traditional metrology applied in pressure acoustics. Based on research using measurements of sound intensity and distribution of vector acoustic field by acoustic orthogonal decomposition method (SI-AOD), the article will present examples of practical applications of these analyses. The described measurement technique, including the method of graphical presentation of results, enriches the knowledge about the mechanism of the flow of acoustic energy stream in real working conditions of the source. The SI-AOD analysis system sets a milestone in the monitoring of sound landscapes and the precise finds noise sources.
