Investigation on Sound Absorption Characteristics of Nonwoven Coir Mats

Conference paper


Due to higher CO2 and other environmental issues, many researchers are working in the production of insulating materials made of natural and bio-based materials. This paper investigates the sound absorption characteristics of porous nonwoven mat made from coir fibre. The produced nonwoven samples were combined with a perforated panel to have hybrid configurations and characterized for acoustic properties. It was found that the developed porous coir mats had good sound absorption values at high-frequency range compared to low-frequency range. When Micro perforated panel (MPP) was placed in front of porous coir mat, the sound absorption characteristic was improved at low frequencies and some samples exhibited good sound absorption characteristics in both low and high frequencies.
