Absorptive noise barrier
2. TYPICAL PROJECTS
PRODUCT COMPONENTS
Using sound – absorbing materials, punch plates,etc. which prevent sound reflection.
Material for panel: Usually use galvanized steel or aluminum sheet with thickness from 1.0 ~ 1.6mm.
Structure of supporting columns and connecting detail: Usually used from H-shaped steel such as H100, H125, H150.., depending on the structural conditions of each type of noise barrier.
Sound absorption standard rating: Noise reduction coefficient – NRC describes the average sound absorption performance of noise barrier.
For the absorptive noise barrier , the NRC will be within 0.6 to 0.9 range (FHMA highway noise barrier design handbook).
