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 ¾inch 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.

A sound absorbing structure comprising a plurality of adjacent, elongated, substantially solid panels each attached to a support strip for supporting the panels in lengthwise and parallel but separate relationship wherein the distance between adjacent panel edges of adjacent panels defines a slot which is between about 1/16 and about ¾inch and wherein said support strips are attached to a substantially solid bottom member such that the adjacent panels together with the support strips and the bottom member form first acoustical resonator cavities in communication with the slots which provide substantial sound absorption at a frequency of less than about 1000 Hz, and second closed cavities between adjacent first cavities for reducing acoustical coupling between adjacent first cavities.
