Preparation Of Sound Absorption Acoustic Panels Using Coir

Abstract

Coir, also known as Coconut fibre is extracted from the outer husk of coconut. Found between the hard internal shell and the outer coat of a coconut. Eco-friendly ligno-cellulosic fibre. Thickest and most resistant of all commercial fibres. Coir is extracted in two forms, white and brown coir. Brown coir is extracted from fully ripe coconuts. It is golden yellow in colour. Completely natural
and biodegradable. The majority of acoustic panels used today contain fibre glass or synthetic fibres, which, if damaged, can harm the eyes and lungs. The US department of Health and Human Services found that the fibres most frequently in traditional sound absorption panels can be reasonably anticipated to be carcinogenic.[1].
