This paper concerns the results of comparative research into the acoustical properties of rubber granulates derived from the recycling of conveyor belts production waste. In the process of recycling it is possible to obtain pure granulated rubber and form... see more

This paper presents the results of the expanded research program on sound absorbing properties of granular materials (granular polypropylene, foamed polystyrene, gravelite, rubber, mineral wool, and high-silica sand) being often applied as sound absorbing... 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

This paper presents a research activity focused on the development of a range of membranes based on distilled bitumen and polymers, specifically designed for high levels of noise insulation from airborne noise. These membranes can be used in multiple laye... see more

Natural product-based noise-absorbing composite can be an alternative to replace synthetic fiber because of its advantages of high strength, toughness, low price, and abundance to reduce noise. The materials used were pineapple leaf fibers with paper wast... see more

This study aims to find an alternative sound-absorbing material from nature that is cheap and environmentally friendly, namely the water hyacinth plant (Eichhornia crassipes). The experimental soundproofing tool from a glass box with a placemat skat was d... see more

As technology advances, the development of equipment used by humans is increasing and most of the equipment produces unwanted sounds that cause noise. To overcome this, an alternative material for soundproofing is needed which is relatively cheap and easi... 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

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
