Modeling the Vibroacoustics Response of Structures With Attached Noise Control Materials

This paper discusses the modeling of the vibration and acoustic response of panels with attached sound packages, using both analytical and numerical methods. Special attention is devoted to the modeling of various types of porous materials (rigid, limp, porous elastic,[[ellipsis]]) in various mounting conditions (single wall and double wall) together with the calculation of various vibroacoustic indicators (vibration response, radiated power, transmission loss, added damping, air-borne insertion loss, Structure-borne insertion loss[[ellipsis]]) under various excitations (acoustical, mechanical and Turbulent Boundary Layer). In particular, examples illustrating the practicality and usefulness of these methods are presented.Copyright © 2011 by ASME
