Noise Generation from Fabric Friction
topic
Fabric friction noise testing slides fabric specimens against each other or standardised surfaces at controlled speed and contact pressure in a sound-attenuating enclosure, measuring sound pressure level and frequency spectrum with a calibrated microphone and calculating psychoacoustic annoyance parameters including loudness, sharpness, and roughness from the frequency spectrum.
Role
Addresses the noise emission performance of garment fabrics during wearer movement, critical for military and hunting camouflage garments requiring acoustic stealth, medical workwear requiring quiet operation in clinical settings, and high-end outdoor apparel where fabric noise is perceived as a quality defect.
