Zusammenfassung:	An enhanced acoustic cell for use in acoustic panels is provided. The provided enhanced acoustic cell has a parabolic-shaped cell floor and a receiving object suspended at its focal point. Components of the enhanced acoustic cell may be easily replicated and installed into a face sheet comprising an array of a plurality of interconnected acoustic cells. The provided acoustic cell, and arrays thereof, may be produced using an additive manufacturing (AM) technology.
