Acoustic Properties of Aerogel Embedded Nonwoven Fabricsm
Original language description
In recent years, silica aerogel has attracted great attention and been extensively used in different technical fields due to its remarkable properties in optics, mechanics, acoustics etc. On the other front, nonwoven fabrics in general are ideal acoustical insulator due to their high volume-to-mass ratio. The material thickness, density, airflow resistance and porosity are important factors in determining the absorption behavior of nonwovens materials. Noise refers to the irregular and chaotic sound which disturbs people?s work and impairs people?s health. Noise control is a vital process in today?s structural design. Urbanization and heavy growth of construction work in every neighborhood emphasize the need of new technologies for noise reduction. There are several methods to decrease noise and one of which uses sound absorption materials.
