- In this study, numerical analysis is performed to investigate the sound radiation characteristics of an
apartment house according to the type of the slab system. In order to satisfy the boundary condition of the
apartment house, the whole floor is modelled with FEM model for three different structural system: wall,
RC, flat slab system. From the analytical results, it is shown that heavy weight floor impact noise of wall
type slab is larger than that of the other slab systems and the noise radiated from the wall have great effect
on the sound pressure level. The results also show that the vibration energy of RC or flat slab system is
widely distributed over the whole slab, which is main reason that the noise induced by the slab systems is
reduced in comparison with wall slab system.
