The far‐field and near‐field solutions for the radiated acoustic pressure from a line‐driven fluid‐loaded, rib‐stiffened thin elastic plate have been obtained. The plate has been configured to have two sets of rib stiffeners, though the formulation given has been extended to include additional rib‐stiffener sets. The stiffeners composing a given set are identical and are spaced periodically with distancel. However, one set of stiffeners is shifted by an amount Δ from the other set. In this manner, portions of the plate may be configured with periodic repeating sections of arbitrary lengthlhaving aperiodic rib spacing. The stiffeners exert reactive forces upon the plate, but not angular moments. Fluid loading is included on the upper surface of the plate while the lower surface is unloaded, except for a time harmonic line force applied normal to the lower surface. The far‐field radiated pressure has been obtained using the method of stationary phase. Numerical integration techniques were used to obtain the near‐field acoustic pressure.
