Abstract
In this study, the effects of fabric weave, density, and fiber fineness on the acoustic absorption characteristics of interior wall covering textiles were investigated. Polyester $100\%$ nonwoven (needlepunching) of uniform fiber fineness were selected for rear acoustic absorbents. For the fabric wall covering textiles, acrylic $100\%$ woven fabrics and polyester $100\%$ nonwoven (needlepunching) of different fiber fineness were employed. The capacity of sound absorption was measured by a two-microphone impedence measurement tube (KS F 2814), and sound absorption coefficients were calculated. Air permeability (ASTM D 737) and surface roughness (root mean square's method) were measured to estimate the structural characteristics of interior wall covering textiles. For surface interior wall covering textiles, sound absorption in the high frequency range increased as air permeability increased, but it was irrelevant to the roughness. On the contrary, sound absorption coefficient increased in the low and medium frequency range, as air permeability decreased. Moreover, with an increase in surface roughness, the sound absorption coefficient increased in the low-frequency range. Based on the results of this study, it is expected that efficient sound absorption capacity through the whole frequency range can be achieved by applying various combinations of wall covering textiles to the interior of a building.
