109 弾性多孔板の吸音特性関する研究(OS4 機械の振動・騒音および制御に関する新技術(2),研究討論セッション)
詳細
Sound fields separated by an elastic plate with a small hole are studied. Sound absorption coefficient and acoustic impedance are calculated and are compared with the measured ones. Furthermore, vibration modes of the air and the panel are discussed at the maximum value of sound absorption coefficient.
