An inter-layer noise problem in the apartment has been issued. An fundamental investigation has been carried in this study. An vibration-acoustic interactive analysis, has been selected to see the relationship between concrete slab thickness and its sound level in the apartment. Results showed that the sound pressure level had been decreased when the concrete slab thickness was increased. These results would be helpful to provide an useful information for developing of a high performance floor slab minimizing inter-layer noise.
