    In this study, we analyzed the changes in vibration characteristics as a function of thickness variations of concrete slabs in apartments, which face numerous issues related to inter-floor noise. To this end, we examined the concrete slab thickness, compressive strength, and air volume at the construction site of a new apartment building in Korea, prior to reviewing and analyzing quality control data. This was done to assess the on-site conditions of the concrete wall structure, which forms the foundation of domestic apartment buildings. Furthermore, the structure and thickness of the field slab were inspected, and vibration characteristics were analyzed using an impact ball, a weight impact sound measurement method that is among the floor impact sound blocking performance measurement techniques. The conditions of the concrete floor slab and factors influencing weight impact sound blocking performance were investigated, with a detailed evaluation in the low-frequency range of 25 Hz ~ 100 Hz.
