• Resumen

  • Noise belongs to negative effects in our environment. One of possibilities of noise elimination is application of suitable materials with good sound-absorbing properties. Porous materials belong in general to materials capable for noise damping. The purpose of this paper is to investigate sound-absorbing properties of selected waste materials with different thicknesses. Experimental measurement of sound absorption coefficient was carried out on Brüel & Kjær 2034 analyzer with Kundt's tube in the frequency range of 16 to 6300 Hz.
