“…At the time of writing this article, topology optimisation has been performed on a variety of acoustic applications, including horns, mu✏ers, rooms and sound barriers [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36] . A majority of these applications use the gradient-based SIMP method or its variants, while a small fraction of them use BESO or level-set methods.…”

“…In order to verify the reliability of genetic algorithm optimization, the optimal noise reduction experiment of one chamber plug inlet muffler was carried out [34,35]. Xu et al used the boundary element method to optimize the distribution of porous material layer in the cavity to improve the absorption effect of porous material, reduce the noise level or increase the dissipated sound energy of porous material [36]. To sum up, the previously reported literature mainly focuses on the structural optimization design of cavity or multi-cavity materials, but does not study the structural optimization of the exhaust tailpipe of a tractor.…”

“…Lagarrigue et al [ 23 ] came with the idea of incorporating the rigid inclusions in a porous material to be tunable and for it to be possible to improve their sound absorption properties at the low-frequency scope. Cellular materials with several types of inclusions differing in shape was studied by Groby et al [ 24 ], while Xu et al [ 25 ] dealt with an optimum design for the propagation of acoustics in the exact material layer inside the cavity using the bounded element method.…”
