It is inevitable to encounter noise in many natural and artificial environments. As stated in the Occupational Health and Safety Regulation, encountering noise and noise above 85 dB (decibel) can cause permanent problems for human health. Various solutions have been developed to protect people from these damages. The use of headphones, moving away from the source of sound and noise, suppression and isolation of sound and noise have made important achievements. The experimentally proven to suppress noise, materials in the form of acoustic foam or sponge, natural fibers (sheep fibers, coconut, tea fiber and hemp fibers, etc.), microfibres obtained from natural and synthetic fibers and glass wool materials should be used. In terms of good acoustic properties; It has been revealed that sponges, woven and knitted fabrics made from natural fibers, fabrics made from microfibers, fabrics made from recycled non-woven surfaces perform well. In addition, as a new study, experimental investigation and analysis of woven, knitted, non-woven surface fabrics or sponges that can be obtained from synthetic fibers, especially acrylic fibers, to suppress noise, to reduce its power, can provide important results. Since porous structures have an important point in sound absorption, important steps can be recorded for the target of the study by selecting them as materials in experimental studies.
