    Abstract

    © 2016 Acoustical Society of America.This paper focuses on the frequency-filtering behavior of the structural vibration and sound radiation of a fluid-loaded plate with periodic inhomogeneities of finite width. The passbands of the flexural waves in the plate and the frequency bands of effective sound radiation from the plate are examined for air and water loading conditions. The mechanisms that generate the differences in these two bands are explained by analyzing the dispersion curves of the waves in the plate and the sound radiation behavior of supersonic wavenumber components in the plate vibration. The effects of fluid loading on the properties of these two bands are highlighted. A parametric study is also conducted to illustrate the effects of the width and magnitude of the inhomogeneities on the sound radiation characteristics.
