Abstract

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.
