Study on the Sound Absorption Properties of Noise Barrier according to the Compositions of Absorptive Material
흡음재 구성방법에 따른 방음벽의 흡음특성에 관한 연구
Abstract
Noise barrier is used to reduce traffic noise. The effect of a noise barrier depends not only on the materials, but also on the physical properties such as density, height and degree of absorption, etc. Typical absorptive noise barrier is used sound absorbing material, such as glass wool and mineral wool. The goal of this study is to develope excellent absorptive noise barrier using a polyester. Laboratory measurements were peformed with various thicknesses, density and layer of absorber in a reverberation room.
