“…Furthermore, the weighted STL of the pure composite rubber reached 12.72 dB, 18.03 dB, 21.37 dB and 23.80 dB with the thickness of 1.0 mm, 2.0 mm, 3.0 mm and 4.0 mm, respectively, which exhibited an excellent sound insulation performance and took little occupied space. The results were basically consistent with the experimental data expressed in the literatures [ 52 , 53 , 54 ].…”

The composite rubber reinforced with hollow glass microsphere (HGM) was a promising composite material for noise reduction, and its sound insulation mechanism was studied based on an acoustic finite element simulation to gain the appropriate parameter with certain constraint conditions. The built simulation model included the air domain, polymer domain and inorganic particles domain. The sound insulation mechanism of the composite material was investigated through distributions of the sound pressure and sound pressure level. The influences of the parameters on the sound transmission loss (STL) were researched one by one, such as the densities of the composite rubber and HGM, the acoustic velocities in the polymer and inorganic particle, the frequency of the incident wave, the thickness of the sound insulator, and the diameter, volume ratio and hollow ratio of the HGM. The weighted STL with the 1/3 octave band was treated as the evaluation criterion to compare the sound insulation property with the various parameters. For the limited thicknesses of 1 mm, 2 mm, 3 mm and 4 mm, the corresponding optimal weighted STL of the composite material reached 14.02 dB, 19.88 dB, 22.838 dB and 25.27 dB with the selected parameters, which exhibited an excellent sound insulation performance and could promote the practical applications of the proposed composite rubber reinforced with HGM.

“…The mesoporous portion and hollow structure significantly prevent the transmission of acoustic waves through the PA/ZSM‐5 composite layer. In comparison to micropores, mesopores and hollow structure in hierarchical hollow ZSM‐5 can provide a greater number of voids and cavities for air trapping, which helps to increase sound absorption efficiency and reduce sound vibrations 17 . Compared to sound insulation materials with fillers such as fibers, hollow glass microspheres, HSNTs, etc.…”

“…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). Mesopore is the most important component to improve the sound insulation effectiveness 17 . It is well known that the addition of high concentrations of inorganic fillers to polymers is responsible for excellent sound insulation 9,18 .…”

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

“…Recently, numerous studies have been carried out to develop such soundproof composites, namely, wood-waste tired rubber composite, 18 inorganic particles/polymer composites and nanocomposites, including polypropylene (PP)/CaCO 3 , 19,20 resin/hollow glass bead, 20,21 poly(vinyl chloride)/mica, 22 rubber/carbon nanotube 23 polyvinylpyrrolidone/graphene oxide, 24 poly(vinyl acetate) mesoporous carbon, 25 and so on. The stiffness enhancement was more important to influence the sound insulation property rather than the density change of polymer composites.…”
