TL;DR: In this paper, the elasticity of urethane magnetorheological elastomers (MREs) consisting of carbonyl-iron particles in a polyurethane matrix were studied.

TL;DR: In this paper, the authors proposed a feedback controller that only uses sensors and actuators in the cavity of the double glazed window to reduce the sound transmission to the zone of interest.

TL;DR: In this article, an analytical model of fully coupled structural-acoustic-HRs within a double wall structure is established, and the authors illustrate the potential of the active control approach using smart piezoelectric materials and different control actuators (i.e., loudspeakers in the cavity, PZT actuators applied to one of the plates) to improve the transmission loss through double wall structures.

TL;DR: The Adomian decomposition method is employed in this paper to investigate the free vibrations of a stepped Euler–Bernoulli beam consisting of two uniform sections and the computed results for different boundary conditions, step ratios and step locations are presented.

TL;DR: In this article, an experimental investigation of passively controlling sound transmission through a double glazed window by using arrangement of Helmholtz resonators (HRs), which are commonly used for narrow band control application, is presented.
