Sound absorbing structures

摘要

The instant invention involves a sound absorbing structure which is formed from at least two adjacent panels which are assembled so as to provide a narrow slot of between about 1/16 and 3/4 inch between the panels. The slot opens into a resonance cavity formed by the panels, their support strips, and a bottom member. The resulting sound absorbing structure provides substantial sound absorption at frequencies of less than about 1000 Hz.
