PURPOSES : In this study, we aimed to develop an absorption and insulation soundproof board with excellent noise reduction ability using waste tire powder.
METHODS : An optimum mix ratio of sound absorption material and sound insulation material was derived through a sound absorption test and a compressive strength test; a combustion test was performed to confirm whether the combustibility evaluation criteria were satisfied. Additionally, to derive a shape with excellent noise reduction ability, noise prediction simulation was performed.
RESULTS : Through the sound absorption test, compressive strength test, and combustion test, an optimum mix ratio of sound absorption material and sound insulation material as well as a shape with excellent noise reduction ability was derived through noise prediction simulation. CONCLUSIONS : An absorption and insulation soundproof board was applied with sound absorption material and sound insulation material developed using waste tire powder. The recycling rate improved; thus, excellent noise reduction ability can be expected by developing not only materials but also shapes.
