A Review of Acoustic Devices Based on Suspended 2D Materials and Their Composites

“…Other studies have also shown the significance of surface micropatterns, as indicated by refs. [132][133][134] These works warrant further in-depth research particularly for suspended 2D material systems.…”

Vibroacoustic Topology Optimization for Sound Transmission Minimization Through Sandwich Structures

“…The frequency lines and/or angles of incident could also be included in the min-max problem, e.g. [43]. The min-max problem of Eq.…”

Design sensitivity analysis of modal frequencies of elastic structures submerged in an infinite fluid domain

“…Over the past several decades, a number of numerical approaches have been proposed to calculate the design sensitivities of the static and transient responses of structural systems, compare of Reference 5 and references therein. Also, the shape and topology sensitivity analysis formulations have been presented for acoustic systems and acoustic‐structural interaction systems, 6,7 and applied to the shape optimization of noise barriers, 8 loudspeaker cabinets 9 and the distribution design of sound absorbing materials, 10 and so forth. Moreover, eigenvalue optimization problems also appear frequently when dealing with the structural stability and vibration analysis.…”
