Acoustic structures in which acoustic septa are located in the angled cells of a honeycomb for reducing the noise generated from a source. The honeycomb used to form the acoustic structure has cell walls that extend at an angle relative to the honeycomb edges such that the depth of the honeycomb cells is greater than the honeycomb core thickness The acoustic septa are formed by inserting planar acoustic inserts into the angled honeycomb cells to form septum caps which are friction-locked within the angled cells and then permanently bonded in place.
