The Evaluation Performance Base of the Vinyl Noise Barrier Prototype

Abstract

In the present, the growth rate of urban society in Bangkok is increasing. Some space had developed to be a residence, condominium and office building. Especially, there are so many of residence around an expressway area. Which had been affected the sound pollution from the traffic on expressway. It was important to specify preventive measurement policy in order to reduce the noise pollution from the traffic by using “noise barrier”. However, the noise barrier that was installed on expressway previously was deteriorated by lifetime. Therefore, It is always needed an efficiency evaluation, improve and develop the noise barrier for an over standard. In this research, it is about the efficiency evaluation of the noise barrier reflection panel type that it was designed and developed by using materials from vinyl and natural rubber. It was improved the quality to be stronger, resistance to the environment, suitable for a new installation and replacement and easy to maintenance, so that the noise pollution can be reduced by the noise barrier from the traffic on expressway efficiently. An efficiency evaluation results show that, the noise barrier reflection panel type which made from vinyl and natural rubber materials can be reduced the noise pollution more than the noise barrier reflection panel type which made from fibre cement (Onduline) and fibre materials that installed previously.
