Mode studies of plucked stringed instruments: Aplication of holographic interferometry

 

Dr Bernard E Richardson presented a paper to the Society on Mode studies of plucked stringed instruments, particularly the Application of holographic interferometry.

The Musical Acoustics group at Cardiff has been long established since Professor Taylor took over as Head of School in 1965. The group have used holographic interferometry for many years to study the vibrations of musical instruments. After a review of the technique and equipment and the particular strengths and weaknesses of this analysis tool, the paper describes measurements on historic, modern, and experimental guitars and related instruments.These studies highlight the effects of strutting and bracing patterns used on the underside of the soundboard and the size and positioning of the bridge, which give insight how the design and construction of these instruments affect their mechanical vibrational properties and their acoustical...
