Description
  • This poster deals with problems of noise and vibrations damping by the help of polyurethane open-cells foams. Materials which were chosen for experiment had different porosity, density and mechanical properties such as tensile strength, Young´s modulus etc. Experiment was consited of two main parts which were, measuring of sound absorption coefficient alpha in frequency interval 50 to 6400 Hz and meassuring of dynamic damping in frequency interval 50 to 2000 Hz. As result from experiment are good noise and vibration damping properties of used materials and their possible application like sound and vibration insulation.
