Abstract
Eco-sustainable materials reduce environmental impact by limiting the use of non-renewable natural resources and the generation of toxic waste, thus contributing to the conservation of ecosystems and the mitigation of climate change. Furthermore, eco-sustainable materials demonstrate a concrete commitment to sustainability, increasing the appeal of a brand towards consumers that are sensitive to environmental issues Companies that adopt such materials often enjoy a better reputation and greater customer loyalty Natural fibers are emerging as a viable choice for sound-absorbing panels in construction because they exhibit favorable thermal and acoustic absorption characteristics, non-toxic nature, and abundant availability. In this study, the use of sheep’s wool fibers as a sound absorption material is specifically explored through measurement and discussion of the absorption coefficient of samples with varying depth. Furthermore, the opportunity of utilizing commercial woven with various types of wool for sound absorption structures, to achieve this, modelled application of wool tapestries are placed at varying distances from a fixed back barrier. This study demonstrates significant sound absorption in specific frequency ranges, conditional on the strength of the rear cavity, affirming the suitability of wool tapestries for tailor-made acoustic interventions. The research highlights the returns of using sheep wool in environmental acoustic applications, demonstrating how the acoustic correction of an environment with the use of material based of sheep’s wool provides results comparable to those of artificial materials traditionally used.
