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.

Key words: Picea genera wood, Growth ring width, Latewood percentage, Sound vibration parameters
