PURPOSE: A constructive structure capable of forming a membrane sheet by using a flexible film material is provided to selectively remove a fixed frequency of noise by controlling the thickness of an air layer and the density of the membrane sheet. CONSTITUTION: A constructive structure capable of forming a membrane sheet comprises a first construction member(110), a second construction member(120) and a membrane sheet(150). The second construction member is arranged to be apart from the first construction member. The membrane sheet is arranged between the first member and the second member. The membrane sheet restricts a first internal space and second internal space between the first member and the second member, respectively. The membrane sheet disperses the noise delivered from the first and second members using membrane vibration. The membrane sheet prevents the delivering of noise to another member. The constructive structure is used as the lightweight partition wall. The first member and second member have the structure, which one or more gypsum boards are laminated. |
