Claim 0:
1. An acoustic core, comprising:
an array of resonant cells, the array of resonant cells comprising a plurality of resonant cell groups, respective ones of the resonant cell groups comprising a plurality of resonant cells, at least some of the plurality of resonant cells comprising:
a partitioned resonant cell comprising a first converging resonant cell and a first diverging resonant cell, the first converging resonant cell and the first diverging resonant cell defined by a plurality of cell walls integrally formed with one another and a partition integrally formed with the plurality of cell walls, the partition at least partially delimiting the first converging resonant cell from the first diverging resonant cell;
wherein the first converging resonant cell defines an upper resonant space delimited by the partition and a top face of the array of resonant cells, and wherein the first diverging resonant cell defines a lower resonant space delimited by the partition and a bottom face of the array of resonant cells;
wherein at least some of the plurality of resonant cells comprise:
a coupled resonant cell, the coupled resonant cell defining a coupled resonant space comprising an antecedent resonant space and a subsequent resonant space, and the coupled resonant cell comprising at least one cell wall having one or more wall-apertures defining a pathway between the antecedent resonant space and the subsequent resonant space; and
wherein the coupled resonant cell is configured as a second diverging resonant cell, the coupled resonant cell located at portion of the acoustic core that has a concave curvilinear profile; or
wherein the coupled resonant cell is configured as a second converging resonant cell, the coupled resonant cell located at a portion of the acoustic core that has a curvilinear profile.
