title = "Vibration and sound field analysis of a holed plate subjected to a rotating sound source",
abstract = "This paper presents the vibration and the corresponding sound field analysis of a holed plate excited by a rotating sound source. The vibration characteristics of the holed plate are investigated by applying a layer of artificial {"}ectoplasm{"} on the entire plate including the holed area. Such an algorithm can avoid a non-unique problem with ill-conditioned mass and stiffness matrices. The external excitation on the plated is from a point sound source in a rotating motion. Rayleigh-Ritz method is performed for obtaining the equations of motion. Then, the dynamic responses can be determined. The radiated sound field, on the opposite side of the plate to the sound source, due to vibration of the baffled plate is found by using Rayleigh's integral. The diffraction field from sound wave propagating through the holes is also formulated. Total sound field is the combination of these two sound fields. Numerical results of the vibration responses of the plate and the associated sound field are showed and discussed.",
