Abstract
The use of effective sound absorbing materials provides noise reduction and environmental improvement in various spheres of human life, including in residential and production premises, transportation and so on. The trends in the field of creating promising acoustic materials for use in industry and transport are considered. The advantages of using the sound-absorbing composite materials based on linen and polymer fiber and components from them for vehicle cabins are shown. The achieved acoustic and mechanical characteristics of the developed materials allow a reduction of internal noise by 3–5 dBA and meet modern safety and noise requirements.
