Abstract
An acoustic liner can include a support layer with a set of partitioned cavities defining a set of cells with open faces, a first facing sheet operably coupled to the support layer such that the first facing sheet overlies and closes the open faces, and a set of internal separator structures within at least some of the set of partitioned cavities.
