The present invention relates to an inter-floor noise absorbing panel. A metal sound insulation panel of high density serves to insulate the sound, and a filler filled in the metal sound insulation panel serves to reduce the noise. A sound absorbing panel of low density and a waterproof/soundproof panel of intermediate density are attached to the top and bottom of the sound insulation panel to absorb the noise generated outside and transmitted to two panels. The panel of high density insulates the noise, and the vibration energy of the noise vibrates the particles of the filler to reduce the vibration. Four sides of the inter-floor noise absorbing panel are bent upwardly, and when the noise spread along the panel reaches an edge of the panel, the noise goes up along the panel. |
