Noise has become serious environment pollution in our daily life and is an increasing public health problem. Noise can have the following adverse health effects: hearing loss, sleep disturbances, feel tiredness, cardiovascular and psycho physiologic problems, performance reduction, annoyance responses, and adverse social behavior. Therefore, it is very important to control or reduce noise from traffic, and in factories, offices, and houses. Undesirable and potentially hazardous noises are a side-effect of a wide range of modern engineering and other purposes. The problem of noise generated within the closed space can be particularly acute, but several practical solutions do exist. The use of textiles for noise reduction is based on two major advantages of these materials, namely low production costs and small specific gravity. In this paper, Basic introduction to acoustic textiles, sound absorbing material factors influencing sound absorption, performance measurement of sound absorbing material & finally application areas of acoustic textiles are covered.
