Abstract

The invention relates to a sheet material (10) for acoustic absorption, comprising a panel (12) which is produced from a porous material (14) and of which one absorption face (18) delimits at least one acoustic absorption cavity (16), characterized in that the cavity (16) is delimited by a resistive skin (20) which is produced integrally with the panel (12), in order to increase the acoustic absorption properties of the material (10) by acting on the contrast in dynamic permeability between the cavity (16) and the air located in the cavity (16).
