Visualization of harmonic starting process for flute sound experiment

Signal analysis based on spectral accumulation has great potential for monitoring the condition of structures using random vibration records excited by natural forces. This article describes cumulative harmonic analysis (CHA) by introducing a spectral accumulation function into Berman and Fincham’s conventional cumulative analysis, thus exploring a potential new area in cumulative analysis. CHA effectively visualizes the feedback process from the flow of air against an edge. In this work, we visualized the harmonic starting process for understanding of physical experiment of musical instrument study especially the flute.
