Abstract

Acoustic absorption structure comprising at least one partition tube to form two types of resonators, method for manufacturing such a structure The invention relates to an acoustic absorption structure comprising at least one alveolar structure, interposed between an acoustically resistive layer and a reflective layer, which comprises a multitude of cells (60) as well as at least one partition tube (62) positioned in one of the cells (60) and configured to delimit in the cell (60) two cavities forming two resonators, the partition tube (62) comprising a flat (72) pressed against and fixed against a flat fixing wall (58') which delimits the cell (60). The invention also relates to a method for manufacturing such a structure. Figure 10
