Floor impact sound, which occurs when children run, is primarily caused by the vibro-acoustic coupling effect. This effect involves the transmission of vibrations from the upper slab to the lower floor through the slab, which is then converted into sound at the ceiling surface. By reducing the vibration, it is possible to reduce the sound transmitted to the lower floor. In this study, a tuned mass damper (TMD) was designed to investigate its vibration and sound reduction performance. Computational analysis was performed to evaluate the effectiveness of the TMD. This study also compared the performance of slabs with and without the TMD as well as investigated the effect of the mass ratio, which is a design parameter of the TMD. The analysis results showed that installing the TMD led to an overall reduction in vibration. Specifically, the noise reduction of the 1st mode reached up to 42 %. However, when the mass ratio of the TMD was increased over a certain level (20 %), noise control performance was not significant.
