| Abstract |
This study aims to propose application of noise barrier and to provide useful data for noise control in construction field by measuring and analyzing the insertion loss(IL) of noise barrier mainly used for specific work. For these reasons, survey on the documents declared before construction was carried out focusing on the construction machine and noise barrier planned and EGI fence with dust net was certified to used generally for noise control and temporary fence.?? ??For the analysis of the effect of noise barrier, IL was measured by indirect method in accordance with ISO 10847. IL depending on the distance between noise barrier and construction machine by 7.5m, 10m, 20m and 30m was compared, and IL depending on the distance of receiving point from noise barrier was also compared by measuring the sound pressure level(SPL) in the reference position above barrier and in each point, 7.5m, 15m, 30m, 45m and 60m, at the same time. Based on the IL measured, examination was performed whether the data were satisfied or not with regulation for life noise. |
