Heavy-weight floor impact noise has characteristic of structure-borne noise which is caused by vibration of a slab. Thus, dynamic property of building should be measured precisely to analyze the causes of floor impact noise. In this study, modal test was performed in the range of floor and walls of residual building and modal parameters such as vibration mode, natural frequency, damping coefficient were analyzed. Also, correlation between structural vibration and sound field were investigated by floor impact noise and vibration measurement test.
