Abstract
A process for the production of an acoustically resistive structure that can be inserted in an alveolar structure so as to obtain a coating for the acoustic treatment, whereby the acoustically resistive structure includes at least one porous layer (34) and at least one reinforcement structure (36) assembled by gluing, the process including:
