- 要約等To estimate changes in the acoustic properties of a wooden xylophone keyboard caused by heat treatment, the resonant frequencies and logarithmic decrement of control and heat–treated specimens of Yezo spruce (Picea jezoensis), Northern red oak (Quercus rubra) and Japanese red pine (Pinus densiflora S. et Z.) were evaluated by the free vibration method. A flexural vibration test was carried out by the xylophone stick free fall impact test. The changes in resonant frequency of the first mode and those of other modes by heat treatment were evaluated. And the changes in logarithmic decrement by heat treatment were evaluated. As ...
