The effect of large amplitude vibration on the pressure

· This study addresses the effects of large- vibration on the pressure-dependent absorption of a structure multiple-cavity system. It is the first study to consider the effects of large- vibration and pressure-dependent absorption. Previous studies considered only one of these two factors in the absorption calculation of a perforated panel absorber
