Cymatics for Visual Representation of Aircraft Engine Noise

Cymatics is a visual representation of sound in form of geometric patterns. It is accomplished by a tonoscope device. In most implementations, dispersed fine particulate matter is placed on a horizontal metal plate (Chladni plate) that is excited by frequencies present in the sound under analysis. Sound, resonances, standing waves and nodes appear as interesting symmetric geometric patterns. Instead of physical implementation, software implementation of the tonoscope can also be used. In this paper noise of various aircraft engines is analyzed. Developed patterns could be potentially used for early detection of impending faults.
