Acoustics characterization of reinforced composite for noise reduction

Abstract

These days, noise pollution is becoming worse due to the faster globalisation of nations, and its effects on human health go beyond hearing impairment. As a result, effective noise pollution control methods are needed. Use a composite reinforced with natural fibres for acoustical purposes. Natural fiber-reinforced composites have several benefits, such as being inexpensive, simple to produce, and eco-friendly. Additionally, natural fibre improves composite sound absorption, structural stability, and mechanical durability. The methods for assessing the acoustical properties of composites improved by natural fibres are described in the paper. Acoustical measures, such as sound transmission losses and absorption efficiency, are also evaluated. This work also examines a factor that influences the mechanical and acoustical properties of composites reinforced with natural fibres. The variables that determine the outcome include the fiber’s characteristics, density, sample thickness, porosity, adhesive material, and filler substance. Increases in the percentage of fibre weight, binder material, and filler material improve the durability and sound absorption of natural fiber-reinforced composites.
