The present invention relates to a noise reduction tire. More particularly, the present invention relates to a noise reduction tire comprising a composite sound-absorbing material layer attached to an inner surface of the tire, wherein the composite sound-absorbing material layer includes a porous foam and a non-woven fabric surrounding the porous foam. Therefore, it is possible to effectively reduce the noise inside the tire by changing the noise energy that causes resonance and the frequency generated accordingly.

    본 발명은 소음 저감 타이어에 관한 것으로서, 더욱 상세하게는 타이어 내측면에 부착된 복합 흡음재층을 포함하며, 상기 복합 흡음재층은 다공성 폼 및 상기 다공성 폼을 감싸는 부직포 외피를 포함함으로써, 공명 발생의 원인이 되는 소음에너지 및 이에 따라 발생되는 주파수를 변경시켜 타이어 내부 소음을 효과적으로 저감시킬 수 있다.
