Many researchers have carried out various studies to control inter-layer noises, the methods to control inter-layer noises effectively have not been suggested until now. Accordingly, this study carried out the comparative analysis with experimental results after evaluations through the numerical analysis for vibration noises caused by heavyweight impact noises, in an effort to evaluate the level of noise reduction through vibration control by segmenting a finish mortar layer with a long span which shows the linear behavior by vibration. As a result of comparisons between experimental results and numerical analysis results, numerical analysis results showed responses similar to experimental results, and each segmentation system appeared similar results. |
