Characterization of acoustic and mechanical properties of common tropical woods used in classical guitarsSproßmann, Robert, Zauer, Mario, Wagenführ, André 14 November 2017 (has links) (PDF)
There is a need of substitution woods for the use in musical instruments because of the limited availabil-ity of some commonly used tropical tonewoods. Before substitutions can be found, it is necessary to knowabout the required properties. Hence, in this paper acoustical, mechanical and physical properties of fourcommon tropical hardwoods (Indian rosewood, ziricote, African blackwood and ebony) were determinedbecause there are less literature values for some properties available, e.g. internal friction, hardness orswelling behaviour. The acoustic properties were determined by means of experimental modal analysis,the mechanical properties by means of static bending tests and tests of the Brinell hardness. For the swel-ling behaviour the volume swelling and also the differential swelling coefficients were determined. Withthe results it is possible to look for new ‘tonewoods’ or to specifically modified woods, e.g. thermally trea-ted wood, to substitute tropical wood species.
