abstract = "In previous studies, theories have been developed and simulations performed to show that properly designed fibrous media can be very effective at reducing structural vibration as well as absorbing airborne sound. Therefore, the potential range of noise control applications for fibrous
media such as glass and polymeric fiber media has been broadened due to this multi-functionality. Since the acoustical, sound absorption properties of these two kinds of fibers are well-known, the current study focused on a comparison of their damping performance when they are used as layered
dampers for a fuselage-like structure: i.e., a panel with frames. A layer of each kind of fiber was modeled as resting on the stiffened panel to simulate the structure, which was then driven by a subsonic pressure wave. The solution for the panel motion was first found in the wave number/frequency
domain, and an inverse transform was then applied to obtain the spatial results. Through model calculations, the structural damping characteristics of these two fibrous dampers were analyzed, and finally, microstructures were designed for each that resulted in optimal damping performance over
the frequency range of interest. Guidelines were also established for the use of these media in structural damping applications.",
