The Application of Nanofibrous Resonant Membranes for Room Acoustics
Nanomaterials, 2023 Solitary sound absorbing elements exist; however, their construction is massive and heavy, which largely limits their use. These elements are generally made of porous materials that serve to reduce the amplitude of the reflected sound waves.

Broadband low-frequency sound absorption in open tunnels with deep sub-wavelength Mie resonators
Frontiers in Physics, 2022 We report both experimentally and numerically that near-perfect absorption of low-frequency sound is realized in an open tunnel embedded with two deep sub-wavelength (0.085 λ) Mie resonators. The resonators are composed of a multiple-cavity structure and

Performance of T-shape barriers with top surface covered with absorptive quadratic residue diffusers [PDF]
, 2008 A previous paper [Applied Acoustics 66 (2005) 709–730] has shown that adding a quadratic residue diffuser (QRD) to the top of a T-shape barrier can provide better barrier performance than an equivalent purely absorptive barrier.
