  • 要約等To compare the standing wave method with two microphone transfer function method in the measuring the sound absorption properties of wood, we measured the sound absorption coefficients of beech wood experimentally in the frequency range of 50 to 1600 Hz by the standing wave method and two-microphone method. The sound absorption coefficient under a continuous frequency range can be estimated in a shorter time by the two microphone transfer function method than the standing wave method. There was almost no difference in measuring the sound absorption coefficients of beech wood at the estimated frequency range using both methods. The so...
