The transmissibility across simply supported, rectangular, thin plates has been determined experimentally and compared, where possible, with the results of existing theoretical calculations. As measured, transmissibility is the magnitude of the ratio of the central sinusoidal acceleration of the plates to the rigid body sinusoidal acceleration of their boundaries. Comparison has been made between the results of transmissibility measurements across plates with central loading masses, plates with seven different straight-rib configurations, and plates with three concentric circular-rib configurations. The added mass in each case equalled the plate mass so that the effectiveness of the added mass in reducing transmissibility could be evaluated as a function of its geometry.
