“…[6,9,10] Another technique to achieve better absorption performance at a lower frequency is the development of different polymeric foams, including polyolefin-based foams. [8,11] Besides, the selection of suitable alternative polymeric foams can resolve the problems associated with undesirable aging properties of polyurethane foams, [12][13][14] along with their great tendency to absorb water, adversely affecting their acoustic performance. [8] Regarding their high flexibility and damping features, elastomers could be an appropriate polymeric matrix for designing porous sound-absorbing structures.…”

“…Note that this measurement already excluded the dependency of the surrounding temperature and humidity on a PU film because the examination environment was set at 32 C and 80 ± 5% during the experiment as already reported elsewhere. 38 The examination sample was connected to 20 g of weight attached to one end of the film and to a wall on the other end. A sandpaper-wrapped rod (#240) was attached to the PU film with constant rubbing to the film with the rotation (7300 rpm), and then, the examination was finished once the film was separated into two pieces.…”

“…Several studies demonstrated that the morphology, quality, and mechanical properties of polyurethane foam materials change in a humid environment. Polyurethane foam materials in the service state underwater are subjected to high water pressure when they are used as repair materials in deep water engineering, and moisture has a higher degree of penetration into the material along its internal micropores [ 70 , 71 , 72 ]. Additionally, the performance of polyurethane foam materials varies depending on the depth of the water environment [ 13 ].…”
