In this study High Density Poly Ethylene (HDPE) with Styrene isoprene styrene block copolymer (SIS) with properties were determined of the sound. A sound absorption material composed of blends of HDPE with SIS developed. Measurements indicate that HDPE ratios have a significant effect on the acoustic absorption performance of the blend due to their microstructures and physical features. There was sound absorption in the frequency range between 100 and 6400 where is high frequency range. The results were filtered via numeric analyses program. In the light of all these data, it was seen that SIS contribution leads to property of acoustics behaviors.
