Sound Insulation Performances of Linters Made of Textile Waste

From the beginning of the 20th century, the use of insulation materials has become a necessity and the production of appropriate materials for insulation is of great importance. Although most insulation materials are produced from inorganic materials, recently, some of these materials have been prohibited due to their suspected health risks. Thus, it is important to look for new materials that can overcome these defects and provide more benefits related to human comfort, environment and health. In this work, we focus on the applying of linters made of textile waste in acoustic insulation. The acoustic parameters were, then, studied for an interval of frequency varied between 350 and 5500 Hz using a kund tube with one microphone. The moisture and thickness effects were analysed for the same frequencies interval. This structure has a sound absorption coefficient greater than 0.55, it varies around 0.96 for the frequencies superior to 2500 Hz and present a minor peak at 1500 Hz. Its reduced impedance ranging for 500 to 2500 Rylds. The moisture has a minor negative effect on the acoustic insulation but the increasing of thickness can promote the sound insulation: extend the optimal insulation range of frequencies.
