Assessment of the fabric's wear by sound measurements on soldier's uniforms

This study focuses on the evaluation of fabrics friction sound using two different approaches (instrumental and sensory) to analyze the influence of fabric wear on friction sounds. For this purpose, four fabrics were selected and have undergone multiple washes (up to 50). A specific device reproducing the human arm motion is used to produce and record the fabric friction sounds. From these recordings, some acoustic parameters like the total noise level can be determined. Meanwhile, a sensory panel dedicated to hearing assessed the friction sounds by several attributes. This paper identifies the significant correlations between acoustic, mechanical and sensory properties
