    Abstract: Moisture in wood has been found to influence properties and performance of wood in service. The hygroscopic nature of wood makes it continuously absorb moisture from the environment and as such render wood unstable. Meanwhile, little or no information has been provided on few acoustic property of wood with respect to moisture. This study thus aim a... Show More
