A middle layer (22) having partitioned cavities (28) is sandwiched between an imperforate sheet (24) and an optional perforate sheet (26) to form a low resistance acoustic liner (22). A preferred method of manufacture of the low resistance acoustic liner (20) uses aspects of the buried septum technique including placing an uncured imperforate septum (36) between a support layer (32) and a partitioned cavity middle layer (22), pressing the middle layer into the imperforate sheet (24) and through the support layer (32), curing the imperforate septum 36 to ...
