Vibro-acoustic analysis of the Veena.
Masters thesis, Indian Institute of Technology Hyderabad.
Abstract
Sarasvati Veena is an ancient musical instrument present in South India. A good amount of literature is available on musical studies and practices but very limited knowledge on construction and systematic mechanical analysis with modern computational tools. Veena is a complex mechanical system
and very good example of structural-acoustic coupled problem. The present work is an attempt to understand dynamical behaviour of Veena with advanced computational tools and experimental methods. Dynamic behaviour formulated by natural frequencies, mode shapes and damping factor. And it is determined by its components like wooden resonator, acoustic cavity, top-plate with the bridge and strings with twenty four fret supports placed in the logarithmic manner over the fret board. Along with the direct sound radiated by plucked string, energy gets transfer through a bridge to a top-plate to acoustical cavity and wooden resonator.
