A method for obtaining a porous acoustic layer, comprising a step of deposition of a plurality of fiber wicks arranged in at least two secant directions, the width, the orientation and/or the spacing of the fiber wicks being determined as a function of the open surface ratio desired for each zone of the porous acoustic layer. A porous acoustic layer obtained according to the method, as well as an acoustic panel comprising at least one porous layer, are also disclosed.
