Normal modes of a radially braced guitar determined by electronic TV holography

Electronic TV holography has been used to determine normal modes of vibration of a classical guitar having an innovative bracing design. The modes observed at frequencies up to 800 Hz are quite similar to those reported in other classical guitars. Observing modes of the air cavity with stationary pl...

Description
Summary:Electronic TV holography has been used to determine normal modes of vibration of a classical guitar having an innovative bracing design. The modes observed at frequencies up to 800 Hz are quite similar to those reported in other classical guitars. Observing modes of the air cavity with stationary plates and ribs helps to understand the normal modes of the guitar. Sound spectra indicate the relative sound radiation by the top and back plates at each modal frequency.
