A novel home-ventilation soundproof structure design based on nature-landscape model

摘要

In this article we bring up two soundproof structures based on muffler theorem which is composed of several channels parts and can be applied to interior design. Unlike general anti-noise structure design, the geometry shape design in this study is adopted by the landscape model. The property of this new design is that the most incident sound pressure will be blocked by the changes of cross section area within the structure region, but also provide enough region for ventilation. Simulations of the overall sound field demonstrate the structure can reduce the incident noise while allowing wind to pass through.
