MACHINERY NOISE CONTROL

Jute can withstand high temperatures and are thus suitable for use in machinery enclosures placed around engines and compressors for noise control. In machinery enclosures they can be used in the inside lining of the walls. Usually such materi­als are faced with perforated sheets, so that most of the material is exposed to the
incident sound field. They can also be used has lagging material around hot exhaust pipes and in HVAC ducts.

In noisy shop floors particularly in a punch press or a forging shop to reduce the reverberant field, usually sound absorber type panels are hung from the ceilings. Such sound absorbing panels can be made of the biocomposites like jute, coir, and cotton. The walls can be padded with biocomposite materials, curtains on factory windows and doors can be made up of such biocomposite textiles.
