“…In previous studies, the simple combinations of polymers and fillers such as mica powder [41], graphene foam [42], and mesoporous silica [43] could not significantly increase the sound absorption of materials at low frequency. In particular, the SAC was hard to increase at a frequency below 1000 Hz.…”

Sound absorbing composites with stratified structures, including double-layer and sandwich structures, were prepared through the combination of nitrile butadiene rubber (NBR) and polyurethane foam (PUFM). The effects of the thickness ratio of layers, different stratified structures and the variety of fillers on the sound absorption performance of the NBR-PUFM composites and the sound absorption mechanism were studied. The results show that the NBR-PUFM composite with a sandwich structure and thickness ratio of 1:8:1 displays good sound absorption, which could be improved further by adding fillers. Because the airflow resistivity, resonance absorption, interface dissipation and interface reflection were combined organically in the sandwich structure, the composites show excellent low-frequency sound absorption performance. Moreover, the composite also has advantages in cost and functionalization aspects.

“…Nanocomposites containing mesoporous materials can be used as sound insulation carriers. Furthermore, the external mesopores also contribute to the sound transmission loss 16 . Huq et al systematically studied the sound insulation properties of microporous activated carbon (AC) and mesoporous carbon nanotubes (CNTs) in a polymer matrix (polyvinyl acetate, PVA).…”

Acoustic materials embed with inorganic fillers in viscoelastic polymers have promising applications in industrial settings. However, optimizing the sound insulation of composites by adjusting the microstructure of nanofillers remains a challenge. In this study, we synthesize adjustable hollow hierarchical Zeolite Socony Mobil #5 (ZSM-5) which can be used as nanofillers in a sound insulation nanocomposite based on the polyacrylate (PA). The results show that the nanocomposites with 0.5 wt% hierarchical hollow ZSM-5 can increase the sound transmission loss (STL) by 33.4%. The maximum STL value reaches as high as 40 dB. The damping properties of the nanocomposites were also improved by adding ZSM-5 into the PA matrix. When the loading of hollow ZSM-5 is 0.5 wt%, the storage modulus increased by 44%, as high as 4486.7 MPa. This strategy opens up a promising way for the sound insulation of composites based on controllable inorganic nanofillers.controllable filler, hierarchical hollow zeolite, sound insulator, viscoelastic | INTRODUCTIONNoise can greatly influence human health and the environment as a result of the growth of modern industrial and transportation systems. The application of sound insulation materials is widely regarded as an effective method to reduce noise. [1][2][3] The lightweight and high performance of polymeric materials are designed to address the typically conflicting engineering requirements encountered in many situations compare to traditional high quality, high density sound insulation materials such as reinforced concrete walls, 4,5 gypsum boards, 6 wood

“…The study confirmed that lattice structures can absorb sound mostly above 1 kHz. Sim et al [9] were involved in the preparation of nanocomposite films of polycarbonate/polyacrylonitrile-butadiene-styrene (PC/ABS), and investigated not only the rheological and mechanical properties of this material, but also its ability to absorb sound. The PC/ABS thin films were made by a simple solvent casting method using phenylene modified-mesoporous silica materials as additives and dichloromethane as a solvent.…”

Noise pollution is a negative factor that affects our environment. It is, therefore, necessary to take appropriate measures to minimize it. This article deals with the sound absorption properties of open-porous Acrylonitrile Butadiene Styrene (ABS) material structures that were produced using 3D printing technology. The material’s ability to damp sound was evaluated based on the normal incidence sound absorption coefficient and the noise reduction coefficient, which were experimentally measured by the transfer function method using an acoustic impedance tube. The different factors that affect the sound absorption behavior of the studied ABS specimens are presented in this work. In this study, it was discovered that the sound absorption properties of the tested ABS samples are significantly influenced by many factors, namely by the type of 3D-printed, open-porous material structure, the excitation frequency, the sample thickness, and the air gap size behind the sound-absorbing materials inside the acoustic impedance tube.
