According to the present invention, a structure for reducing floor to floor noise with a functional sound absorbing member inserted therein is supported by a support frame in a slab; a ceiling member finishes the ceiling after forming an installation space under the slab; supply and discharge pipes and cable wiring pipe are installed in the installation space; and a soundproofing layer is formed by filling an incombustible sound absorbing member in a spare space remained after installing the supply and discharge pipes and cable wiring pipe. According to the present invention, vibration can be removed while suppressing impact by weight from the upper floor and achieving an equilibrium for reducing friction. Sound propagation can be prevented by sealing, anti-vibration, etc. Noise from a room in the lower floor can be absorbed. The structure for reducing floor to floor noise with a functional sound absorbing member inserted therein can be installed within three to four hours without moving a living space; and enables users to reuse the structure in a new apartment by simply collecting the structure when moving to a new apartment. |
