Abstract: The invention relates to a sound absorption device which comprises a multilayer structure (10) crossed by a plurality of channels (1) forming a porous network and making the device pervious through the body thereof (e). Said channels (1) have changing sections and are the result of stacking conduits (2) formed in the respective layers. The multilayer structure includes at least two stacked layers having a similar thickness, the thicknesses of the two layers being defined by the distance measured between two successive discontinuities (3) of said porous network. The section shifts or transitions in the stack of elementary layers (11, 12, 13, 14, 15, 16, 17, 18, 19) offer channel geometry having improved sound absorption compared with a homogenous stack (in-phase stack) of elementary layers. Said arrangement enables better scattering of obliquely incident sound fields.
