Portable stand used to visualize acoustic fields surrounding machines

Abstract

Visualization of the parameters of acoustic field is a relatively new research technique that allows for illustrate the parameters characterizing the acoustic field for specific points of space near the machine. Images obtained in this way have many applications in the analysis of prototype devices, construction, as well as in the analysis of the acoustic field around industrial machines. The article presents the principles of operation of the mobile experimental setup. The results of studies of noise emission on the example of loudspeaker set and vacuum pump are also discussed.
