In the modal analysis, vibration patterns, natural frequencies and damping values of the instrument body are obtained. Since the sound characteristics of the instruments are largely determined by these vibrations, I use the modal analysis method in most of my instrument acoustics studies. Especially when the results of this analysis are compared with the results of acoustic analysis, important information can be provided about the sound formation process in the instruments.
Modal analysis is possible with various techniques. I usually use the mobile hammer test in the laboratory, where detailed results can be obtained. But in the workshop environment, Chladni Analysis, which I prefer because of its ease of application, gives important information about the vibrations of the instrument. Due to its importance in instrument acoustics, I took Chladni Analysis under a separate title.
