Comparison of Acoustical Properties of Mulberry Wood with Some Other Species in Musical Instrument Manufacturing

To evaluate and compare the properties of White Mulberry wood to some other wood, acoustical and musical features of the free vibration on free-free bars in longitudinal-radial and longitudinal-tangential planes were investigated. Ten pieces of each species of White Mulberry, Maple, Beech, Poplar, Caucasian oak, Pine Silvestris, Walnut and Japanese Zelkova with dimensions 20 (tangential) × 20 (radial) ×360 (length) mm devoid of any appearance defects such as cracks, knots, rots, etc. according to ISO 3129 standard were selected and values of dynamic modulus of elasticity, damping factor, acoustic coefficient and sound velocity were measured and compared with each other. The results showed that the acoustic properties of White Mulberry were of inferior quality to other species of the research, especially for Tar construction. While according to criteria of investigation in this research Maple wood and Pine Silvestris species have the best properties in the construction of Tar. It can be claimed, in general, that if the ignoring the timbre of White Mulberry wood, the other investigated species of this study have more suitable acoustic properties than White Mulberry in musical instruments’ construct.
