REACTIVE ACOUSTIC SILENCER |
摘要 |
<p>An acoustic duct silencer is disclosed having opposed sidewall baffles which are disposed in a duct such that a cavity is defined between the baffles and the adjacent duct sidewalls, the space between the baffles bordering a passageway in the duct for the flow of a fluid medium therethrough. Each baffle features an array of generally parallel, spaced-apart elongate slots which substantially span the vertical or horizontal breadth of the baffles. The baffles preferably have a relatively large effective thickness so that the slots formed therein have a significant depth to them. In this manner, an integral array of resonators are provided having a significant slot or throat depth for the attenuation of low frequency sound.</p> |
