The changes in sound absorption capability and air permeability of Malas wood after high temperature heat treatment were investigated. The average air permeability of Malas in longitudinal direction after heated under the temperature of 190℃ during 3 hours was about 23.48 darcys and that of control was about 3.11 darcys. The noise reduction coefficient of Malas specimens were 17% for treatment and 10% for control. The mean of sound absorption coefficient of specimens in the frequency range of 50~6,400 Hz were 42% for treatment and 17% for control, respectively.
