“…The relationship between sound absorption and physical properties of these samples was investigated by measuring the sound absorption coefficients from 250 to 2000 Hz with an air gap behind the specimens. According to this paper 3 and corroborated by others, 1,4,8 the acoustical absorptive behavior of highly porous fiber assemblies is strongly dependent on the air motion, resulting in frictional losses in the pores of the nonwoven.…”

“…A number of studies have been carried out in sound absorption related nonwovens for assessment of the influences of structural factors [17][18][19][20][21]. The frictional resistance between fibres causes absorption of sound in nonwovens.…”
