Operating Deflection Shapes of the Plates and Standing Aerial Waves in a Violin and a Guitar Model
Abstract:Phase modulated TV holography is used to measure sound pressure variations of standing waves of the air inside cavities of transparent models of a violin and a guitar. The accompanying motions, the Operating Deflection Shapes (ODSs) of the now white painted walls of the enclosures are measured using TV holography. Experimental measurements of the ODSs are compared to finite element calculations of the coupled air cavity and plate motion.
