Abstract
The acoustic-vibration parameters of E. urophylla, including specific Young's modulus (E/ ), coefficient of sound-radiation resistance (R), and sound resistance ( ), before and after heat treatment were measured and characterized. Conditions for the heat treatment included N2 as the protection gas and temperatures of 210 øC, 220 øC, and 230 øC with holding times of 2 h, 3 h, and 4 h. The results showed that specific Young's modulus, and the coefficient of sound-radiation resistance increased, whereas sound resistance decreased, thereby improving the acoustic performance of the wood. The maximum increments were 9.31% for specific Young's modulus (210 øC, 3 h), and 18.68% for the coefficient of sound-radiation resistance (230 øC, 4 h). Conversely, the maximum decrease in sound resistance was -11.27% (230 øC, 4 h). Overall, the acoustic-vibration performance of E. urophylla was improved through heat treatment, with the best vibration performance obtained at 230 øC with a holding time of 4 h.
