Research on Obtaining Biocomposite Structures with Sound Absorbing Properties

The paper addresses the methodology for obtaining biocomposite structures from waste, with sound-absorbing properties, such as: thuja shells, walnut pistachio beech sawdust, pumpkin seeds shells and sunflower shells. experimental analysis carried out considers study of properties held by proposed new materials, determining value sound absorption coefficient, reflection impedance ratio, using Kundt tube. interpretation results obtained evaluation biocomposites shows that they have properties. Consequently, panels soundproofing can be made these which used in industry, transportation, construction, etc. as well decorative purposes spaces cinemas, malls, spas,
