Noise transmission from a curved panel into a cylindrical enclosure: Analysis of structural acoustic coupling

Abstract: Much of the research on sound transmission through the aircraft fuselage into the interior of aircraft has considered coupling of the entire cylinder to the acoustic modes of the enclosure. Yet, much of the work on structural acoustic control of sound radiation has focused on reducing sound radiation from individual panels into an acoustic space. Research by the authors seeks to bridge this gap by considering the transmission of sound from individual panels on the fuselage to the interior of the aircraft. As p… Show more

“…Further work on the active control of sound from the composite plate using a PVDF actuator is due to Kim and Yoon [19]. Henry and Clark [20,21] demonstrated the structural-acoustic control of an aluminum cylindrical panel coupled to a cylindrical enclosure using monolithic piezoelectric actuators. Their research brought out the important implications [20] that the curvature of a panel substantially affects the dynamics of the panel, the integrations of the transducers and the bandwidth required for structural-acoustic control.…”

“…Henry and Clark discussed noise transmission from a curved panel into a rigid-walled cylindrical enclosure. The coupling of the panel with attached piezoelectric actuators to the interior acoustics of the cylinder was carefully considered in their model [29]. Hagiwara et al explored the reduction of noise inside a cavity by piezoelectric actuators.…”

“…All of these methods essentially utilized the assumption of a rigid boundary condition for the acoustic enclosure and most assumed simply supported, or clampedclamped plates. There are numerous works including those by Henry and Clark [40], and Fischer and Hayek [24] that discuss the approach for modeling the acoustic structure coupling in a variety of geometries and boundary conditions. All of these methods approached acoustic structure coupling from a standpoint of two independent systems that are gyrostatically coupled.…”
