In the present work, sound transmission loss (STL) of two plates functionally graded sandwich structures with a porous core is studied. The plates are modeled by first-order shear deformation theory. To obtain an acoustic metamaterial plate with the greatest STL, a functionally graded porous (FGP) plate with a tuned mass damper absorber is used. The obtained results show that using a FGP plate or using only an absorber is sufficient for increasing sound transmission loss, but the simultaneous use of them is effective in higher frequencies.

“…Acoustic metamaterials have several unmatched advantages over ordinary materials as a result of their negative properties at particular frequency ranges (Cheng et al, 2008; Wang et al, 2022; Zhao et al, 2021). More importantly, the sound wave would be manipulated inside certain frequency ranges, that is, band gaps, and the energy would be attenuated when the wave propagates (Wang and Mak, 2012).…”

Presently, noise pollution in ducts is considered seriously, and numerous studies concerning sound absorption in pipes are ongoing globally. Aiming at the difficulty to eliminate the low-frequency noise in pipeline, a multi-resonant cavity duct metamaterial is proposed. The acoustic properties of the metamaterial are calculated using the energy method based on the Hamilton principle and the transfer matrix methodology. The result demonstrates that the duct metamaterial, due to its band gaps and negative bulk modulus, obtains several sound absorption peaks and is advantageous to sound elimination in low frequency. The good acoustic characteristics of the duct metamaterial for sound insulation can be attributed to the plate-cavity interaction. Parametric analysis of the proposed structure is also carried out. This study demonstrates the application prospects of duct metamaterials for multi-frequency sound absorption in engineering practice.
