A Plan on Propagation Process of Environment Vibration

환경진동의 전달경로 대책

This study introduces the basic concepts of the vibration reducing methods and presents a case study of 'A' apartment construction site which located nearby railroad. The site is only 60m away from the railroad. Therefor much noise and vibration damages could be expected during train or any other transportation's passing. Especially, the first and second floor may suffer much vibration with the low frequency radiation noise from the walls and floors. This study estimates the noise level of indoor area by measuring the vibration of indoor walls and floors. From this result, vibration barrier, as a method to reduce the noise level which exceeds proper standard value, was attempted to protect vibration transmit from the railroad.
