摘要： PROBLEM TO BE SOLVED: To provide a sound-proof wall which displays the sound shielding function in a wide frequency range, when sound-proof member to cut off the transmission of the sound from one side to the other side partitioned by both wall members, is provided between the both wall members, in a simple structure and at a low cost. SOLUTION: A porous sound-proof member 14 is composed in a structure internally furnished with a damper 14a abutting to the inner surfaces of wall members 12 and 13, by providing at the position to be the body of the vibration mode between the wall members 12 and 13; and a sound absorber 14b interposing between the inner surfaces of the wall members 12 and 13 and positioning between the body and the node of the vibration mode between the both wall members 12 and 13. And in this case, the vibration of both wall members 12 and 13 is damped by the damper 14a, while the vibration is absorbed by the sound absorber 14b.

And the vibration of both wall members 12 and 13 is damped by damper 14a, the noise is absorbed by the sound-proof member 14b and the damper 14a functions as a dynamic damper.
