Publication number: 20160071507Abstract: 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.Type: ApplicationFiled: November 22, 2013Publication date: March 10, 2016Applicant: Mokpo National Maritime University Industry- Academic Cooperation FoundationInventor: Sang Hoon KIM
