Use of fibrous materials in acoustic insulation applications

In daily life, human beings are exposed to disturbing environmental effects. Sound pollution is one of the most disturbing environmental effects for human. In recent years, researchers have evidenced that sound pollution affects human psychology and health negatively. In order to avoid negative effects of sound pollution, a variety of materials providing acoustic insulation are produced commercially. Furthermore, acoustic insulation properties of new materials have been investigated. Use of fibrous materials in acoustic insulation applications has been researched since fibrous materials are economic, light and they have high physical properties. In addition, porous structure of fibrous materials is an advantage to use these materials in acoustic insulation applications.
