Acoustic properties of aerogel embedded nonwoven fabrics

Popis výsledku v původním jazyce

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. This research examined the sound absorption properties of aerogel embedded (Polyethylene/polyester) nonwoven fabrics at different frequencies from 50 to 6400 Hz in the third octave frequency band. The impedance tube method was used for measuring the acoustical properties of the nonwoven fabrics. In thismethod, sound absorption coefficient was determined at each frequency in accordance with the ISO 10534-2 standards. The results showed that the aerogel embedded nonwoven fabrics have higher sound absorption coefficient which is suitable f
