Shortage of site suitable for housing caused by rapid urban development has led to a construction of the high-rise apartment complex along the roadside. This gave rise to the increasing number of population exposed to the traffic noise. Nowadays, transparent noise barriers are used to replace the conventional noise barriers to solve the problems such as maintenance and urban landscape. However, transparent noise barriers have also several problems such as discoloration, stains and scratching to

In this study, it was focused to compare the soundproofing performance according to the type of polymer materials and panel structure to development of eco noise barrier. As a result, it was observed that PE and PP showed similar a soundproof performance with PC. And in case of soundproofing panel with double layer, sound insulation performance is improved about 17% compare to soundproofing panel with single layer.
