Notes
The sound absorption rates of mandarin peel – sawdust composite boards with the density of 0.4 g/cm³ and the mandarin peel content of 40 percent, measured by reverberation room method and transfer function method, were compared in this study. The results of this study were as follows: The sound absorption rate measured by transfer function method was about 10 percent lower than that of reverberation room method due to sound reflective silicon O–ring, however, generally the sound absorption rates measured by both transfer function method and reverberation room method were almost same. Therefore, it is advised that the sound absorption rate can be measured by transfer function method due to its convenience in preparing specimens, less consumption of specimens and quickly measurement.
