Abstract
Violins were invented in the 16th century in Italy, many methods of manufacturing and adjusting have been developed. Certain violins are highly valued from a cultural perspective as well as for their high sound quality. However, Violin repairers have carried on techniques that have largely been transmitted verbally from generation to generation, so there is a little detailed documentation. Much research has been done to elucidate manufacturing technology and materials used for these valuable violins. This study aims to support the passing down of certain techniques from an acoustic engineering perspective. Many elements defining the timbre, but this study will be focusing on the sound post and the bridge. By clarifying the relationship of adjusting the sound post to the Spatial Radiation Characteristic, we will estimate the ideal position of the sound post and attempt to present the results in the form of a graph.
Highlights
Previous study [1] relating to this is “A Consideration on the Sound Radiation Pattern of Violin” by Yuya Nishimura
An analysis of sound post adjustment and spatial radiation characteristic was made to estimate the ideal position of the sound post
It is apparent that increasing the contact area between the sound post and top/back plates by adjusting the sound post vertically, improved the timbre
Summary
Previous study [1] relating to this is “A Consideration on the Sound Radiation Pattern of Violin” by Yuya Nishimura. An analysis of sound post adjustment and spatial radiation characteristic was made to estimate the ideal position of the sound post. This study as well as sound post analysis, we aim to prepare a suitable environment for editing CAD data. The violin body constitute by a large number of parts.
