Title:

The aerated type or let-flow type sound insulating wall of water which has a resonance chamber for noise insulation around a ventilating passage or a water flow passage

Document Type and Number:

Japanese Patent JP6246900

Kind Code:

B2

Abstract:

At least one resonance chamber is disposed around an air passage channel passing through a window or a wall, and the air passage channel and the resonance chamber are separated from each other by a porous sound absorber. When sound and air pass through the air passage channel, the sound is absorbed and cut off by the resonance chambers, and the air passes through the air passage type channel. As a result, an air passage type soundproof window or wall through which the air passes and by which the sound is cut off can be manufactured, and a water passage type soundproof window or wall through which water passes and by which the sound is cut off in the same principle can be manufactured.
