摘要：

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 in turn gave rise to the increasing number of population exposed to the traffic noise. Nowadays, transparent noise barriers are used, replacing 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 which bring about loss of initial advantages. In this study, it was focused to compare the soundproofing performance according to the type of polymer materials and panel structure to develop eco noise barrier. As a result, it was observed that polyethylene and polypropylene showed similar soundproof performance as polycarbonate. And in case of soundproofing panel with double layer, sound insulation performance is improved about 17% compared to soundproofing panel with single layer.
