Analytical expressions are derived for the vibration and far-field acoustic radiation from a fluid-loaded laminated composite plate, which is excited by three types of mechanical drives: point, line, and uniformly distributed forces in longitudinal and transverse directions. Through numerical results, it is shown that the lamination schemes of the laminated composite plate play an important role in its far-field acoustic radiation, especially when the plies of the plate are asymmetric with its middle plane. This paper would help better understand the main mechanism of acoustic radiation from laminated composite plates, which has not been adequately addressed in its companion paper (Yin, et al., 2007, “Acoustic Radiation From a Laminated Composite Plate Reinforced by Doubly Periodic Parallel Stiffeners,” J. Sound Vibrat., 306, pp. 877–889).
