An analytical model is developed for examining the vibro-acoustic properties of a fluid-loaded plate reinforced by periodic ribs of finite width. This model is used to understand the frequency filtering properties of the flexural wave and the structural-borne sound wave of the ribbed plate under different fluid loading conditions. The relationships between the flexural waves and the related sound radiation in their pass-bands due to the filtering effect of the periodic ribs are specifically investigated. The dispersion relations of structural and radiated waves of the plate due to the periodic configuration of the ribs are used to explain the changes in the vibration and sound radiation response.
