SOUND-ABSORBING MATERIAL AND MANUFACTURING METHOD THEREOF

PARK BYUNG EUN

The present invention relates to a sound-absorbing material to efficiently absorb noise of a specific sound range, and a manufacturing method thereof. According to the present invention, a sound-absorbing material for a building comprises a resonance layer; consists of a mixture of an organic and a ferroelectric material; and the ferroelectric material is used as an inorganic or organic material, preferably including a metal powder. Also, an elastic layer is formed on a lower part of the sound-absorbing material.

본 발명은 특정한 음역대의 소음을 효율적으로 흡수할 수 있도록 된 흡음재와 그 제조방법에 관한 것이다. 본 발명에 따른 건축물용 흡음재는 공명층을 구비한다. 유기물과 강유전 물질의 혼합물로 구성된다. 그리고 강유전 물질로서는 무기물이나 유기물이 이용되고, 바람직하게는 금속 분말이 포함된다. 또한 상기 흡음재의 하측에는 바람직하게 탄성층이 구비된다.
