Richardson, B. Mode studies of plucked stringed instruments: Application of holographic interferometry.
The acoustics group at Cardiff 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 will describe 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 function.
