Acoustic and elastic properties of wood used for musical instruments

Abstract

This paper proposes an ultrasound method for determining the elastic properties of anisotropic orthotropic materials used stringed instruments (in our case violins) manufacturing. Samples from different wood species were subjected to the propagation of the ultrasonic wave front, the signal being received through a receiver. The sensors were placed successively on the three main orthogonal directions of the wood, obtaining the values of the ultrasound velocity in different directions. Subsequently, based on the mathematical relations, the values of elastic parameters were calculated.
