Existing apartments(30 years over) has increased to try remodeling by the aging of it. However, the existing apartment has a low story height. So it is difficult to increase the thickness of the slab. Therefore, in this study, while maintaining the story height, we are looking for a scheme that can be allowed to enhance the tensile strength of the slab to reduce the floor impact noise. Steel, carbon fiber and carbon panel, a reinforcing material, were examined to reduce the performance of the floor impact noise. As a result, the heavy weight floor impact noise showed the effect of reducing 1~3 dB, and the light weight floor impact noise was not reduced.
