Abstract

Foamed aluminum is an eco-friendly material that is reusable and safe against fire. These superior characteristics have many advantages in the field of building and construction and in cruise ships as sound absorbers. So far, the research on foamed aluminum has been focused on the sound absorption performance using the foaming ratio. Foamed aluminum, when compared with the existing sound absorbers such as glass wool or rock wool, has a better structural performance, and it can be installed on walls in many different ways. This study conducted experiments on the sound absorption characteristics considering the various applications of foamed aluminum. The effects of painting surfaces with the finishing material were compared to that of the normal surface, and the effects of vertical installation and hanging from the ceiling was compared with the effects of installing on the floor.

발포알루미늄은 친환경 재료로서, 재활용이 가능하며 화재에 안전하여 선박과 해양구조물에 사용되는 흡음재로서 우수한 특성을 가지고 있다. 지금까지 발포알루미늄은 발포율에 따른 흡음성능에 관한 연구가 주로 이루어져 왔다. 발포알루미늄은 기존에 사용되어 왔던 글래스 울, 락 울 등과 같은 섬유질 흡음재와 비교할 때, 강도면에서 우수하기 때문에 다양한 방법으로 시공할 수 있는 장점이 있다. 따라서 본 연구에서는 공간 내에서 발포알루미늄의 다양한 사용 방법을 고려하여 흡음특성에 대한 실험을 실시하였다. 또한 마감재로 페인트 칠에 따른 특성을 포함하여, 양면흡음재로서 사용될 경우 벽면에 수직으로 세워서 시공한 구조와 공중에 매달아 수평으로 시공한 구조에 대한 흡음특성의 변화에 대해 실험적 방법으로 분석하였다.
