Silicone rubber (SR) is known as stable and able to get through an extreme environment. Moreover, the combination of SR and natural fiber as the composite for the sound absorption application is still limited. For this reason, this study was aimed to fabr... see more

Ethylene-Vinyl Acetate (EVA) polymer foam was prepared using a mold for this investigation. The effect of the cell structure parameters and pore filling gas type on the sound absorption performance of the EVA foam materials were analyzed in terms of their... see more

Flexible polyurethane (PU) foams with varying polyethylene fiber contents were synthesized to improve their acoustic performances. The purpose of this study was to investigate the effects of different polyethylene fiber contents of the PU foams on the res... see more

This paper presents the feasibility of superhydrophobic films to create the nano-lotus leaf effect on concrete surface and their influence on sound absorption and friction properties of concrete for application in rigid pavements. The study involved an ev... see more

Noise pollution has become one of the four major pollution issues in the world and has drawn much attention recently. Controlling the sound source and using sound-absorbing materials reasonably is considered an effective way to reduce noise. Due to the hi... see more

Natural fiber and wood are environmentally friendly materials with multiscale microstructures. The sound absorption performance of flax fiber and its reinforced composite, as well as balsa wood, were evaluated using the two-microphone transfer function te... see more

Noise exposure can occur at any time and interfere with a person's psychological and biological condition. Alternative materials from banana midrib and soybean dregs can be used as sound absorbers based on their characteristics and abundance. This researc... see more

The object of research is the sound field from linear sound sources around noise screens. The decrease in sound levels with the screen is primarily due to the geometric dimensions of the screen and the relative position of the screen and the sound source.... see more
