Ancuta BORLEA (TIUC), Tiberiu RUSU, Ovidiu VASILE Using Particles of Recycled Rubber when Making Some Soundproofing Materials


Abstract:
Waste rubber cause both health and environmental problems and this has forced governments to develop laws for recycling. Using particles of recycled rubber in the domain of soundproofing materials is of major importance from a technical, economical and ecological point of view. In this paper we determine the ability of sound absorption of each obtained material by measuring the sound absorption coefficient depending on frequency, using the impedance tubes. Materials, as composite materials prototype, were made from particles of recycled rubber and a polyurethane binder, in combination with other materials existent on the market (cork of fabric). Keywords: recycled rubber particles, acoustical materials, sound absorption coefficient
