摘要: Sound absorption capability and anatomical features of the organosolv pretreated Japanese larch yellow poplar wood were estimated by stereoscopic observation two microphone transfer function method. capabilities treated wood, in entire frequency range (50~6,400 Hz), higher than those control specimen. Especially, wood`s measured 2~4 kHz about times By pretreatment (at ), weight loss occurred less 1% total porosity increased slightly. In addition, it was presupposed that microstructural changes during this structural cause increasing sound wood.
