Abstract

In this paper, we introduce the new concept of acoustic silencers that disable noise to pass but permit the air ventilation. Conventional sound proofing structures prevent air ventilation between the interior and exterior where the sound is generated and propagated. Therefore, those sound proofing structures are hardly utilized in air flowing duct system or heat exchanging system with the needs of sound insulation. A design proposed in this paper has a shape of airfoil with narrow neck and empty cavity so that it acts like a Helmholtz resonator based acoustic metamaterial. This structure can be inserted in the air flowing duct and reduce the sound passing through the duct but does not resist the air flowing in the duct. Two different combinations of radii and cavities interact with each other so that the opposite phase of sound radiated from the neck makes the destructive interference, and the high transmission loss can be realized concludingly. The airfoil-shaped acoustic metamaterial can provide large open area and low flow resistance due to its geometrical concept, it is optimized in air ventilation as well. It is expected that the acoustic metastructure of the airfoil shape can be applied to various engineering problems that simultaneously deal with flow problems and noise problems, such as HVAC systems.
