Effect of hygro-thermal treatment in the acoustic characteristics of the wood of Quercus scytophylla Liebm.
The influence of hygro-thermal treatment in the acoustic characteristics of Quercus scytophylla wood was studied. 30 specimens without treatment and 30 with treatment were tested in bending vibration (free-free supported). Density, moisture content, natural frequency, modulus of elasticity in bendin...

| description | The influence of hygro-thermal treatment in the acoustic characteristics of Quercus scytophylla wood was studied. 30 specimens without treatment and 30 with treatment were tested in bending vibration (free-free supported). Density, moisture content, natural frequency, modulus of elasticity in bending vibration, specific modulus, logarithmic decrement, damping coefficient and acoustic coefficient were computed. Statistical analyses demonstrated that natural frequency is a good predictor of the modulus of elasticity and that hygro-thermal treatment modified significantly the density and logarithmic decrement. |

La madera del género Quercus presenta un potencial importante como material para la elaboración de productos de madera con alto valor agregado. Con el objetivo de verificar si un tratamiento higro-térmico aplicado a la madera de Quercus scytophylla, modifica de manera significativa su módulo de elasticidad y sus propiedades de amortiguamiento, se estudió el efecto del tratamiento en sus características acústicas. Se ensayaron 30 probetas sin tratamiento y 30 con tratamiento en vibraciones transversales y se calcularon los parámetros densidad, contenido de humedad, frecuencia natural, módulo de elasticidad, módulo específico, decremento logarítmico, coeficiente de amortiguamiento y coeficiente acústico. Análisis estadísticos demostraron que la frecuencia natural es un buen predictor de los módulos de elasticidad y que el tratamiento higro-térmico modificó significativamente la densidad y el decremento logarítmico.
