Document Type and Number:
WIPO Patent Application WO/2014/175526
Kind Code:
A1
Abstract:
A window or a wall is made, an air passage channel (10) passing through the window or the wall is made, at least one resonance chamber (r1, r2, and r3) is disposed near the air passage channel (10), and the air passage type channel and the resonance chamber are separated from each other by a porous sound absorbing material (30). When sound and air pass through the air passage type channel (10), the sound is absorbed and blocked by the resonance chambers (r1, r2 and r3), and the air passes through the air passage type channel (10). Using this, the air passage type soundproof window or soundproof wall by which air passes therethrough and sound is blocked can be manufactured, and using the same principle, the water passage type soundproof window and soundproof wall by which water passes therethrough and sound is blocked can be manufactured. The present invention can be applied to various industrial fields in which noise is generated by an air blower, and can be used for constructing a quiet ecological environment of epibenthos.
