摘要

Using ASTM E 1050,the sound absorption coefficients of four aesthetically pleasing (to vision and touch) velour nonwoven fabrics,and of the stacked velour fabrics and high-loft pads that make trunk lining systems,were determined.The trunk lining systems have excellent sound absorption capabilities (e.g.,coefficients of 0.825-0.995 at 3,000 Hz and 0.735-0.995 at 2,500 Hz) and are used as soundproofing materials in European automobiles.Velour nonwovens are attractive because of the silky,soft hand of the short,thick pile giving a rich textile-like feel that is compliant,pliable,and inexpensive.
