Abstract

© INTER-NOISE 2019 MADRID - 48th International Congress and Exhibition on Noise Control Engineering. All Rights Reserved. Chicken feathers are an industrial waste that can be used to form sustainable materials suitable for use in sound insulation applications. Clean and disinfected waste chicken feathers were processed into fibres and these were air laid using commercial pilot plant facilities to form non-woven feather fibre composite mats. Varying the composition and processing conditions produced mats with different density, thickness and weight per unit area. The sound absorption coefficients of the non-woven feather fibre composites were determined using the impedance tube method. The tests used normal incidence and were completed over the frequency range from 63 and 1,600 Hz. The performance of feather fibre mats were then compared to commercially available sound absorption products.
