【Abstract】 In this paper eight \%Picea\% genera wood were selected to determine and compare the sound vibration parameters of Young’s module,loss tangent (tan δ ) and E/G under bending vibration condition.The relationship between these parameters and growth ring width and latewood percentage was analyzed.The results of this study could be a basis of evaluating the quality of \%Pices\% genera wood for musical instrument and establishing the method of reasonably using the parameters of growth ring width and latewood percentage in the selection of wood for musical instrument production.更多还原
