Abstract
A theoretical model was developed to evaluate the reduction of flexural wave that is generated by a line force applied on an infinite plate using a compliant baffle. The compliant baffle layer placed between the plate excited by a line force and a signal conditioning plate is designed for reducing pressure fluctuations from the vibrating plate. The baffle layer considered here is the compliant‐tube array, modeled by Junger [J. Acoust. Soc. Am. 78, 1010 (1985)] to represent a homogeneous (dispersive) fluid layer. Effects of various parameters such as the aspect ratio of the compliant tube, the distance between tubes, and the damping of the tube material on the flexural wave reduction are presented. Calculations of noise reductions were made for both the dispersive and nondispersive fluid baffles.
