Abstract
A process for the production of an acoustic treatment panel that can be connected at a surface of an aircraft, in particular at a leading edge such as an air intake of an aircraft nacelle, whereby the panel includes an acoustically resistive layer (), at least one alveolar structure (), and a reflective layer (), and channels () placed between the alveolar structure and the acoustically resistive layer, each channel being bordered by a wall (), the process including deforming a layer so as to produce furrows at one of its surfaces, flattening and making integral the deformed layer () with the acoustically resistive layer so as to border the channels, and removing material in such a way as to eliminate at least a portion of the thickness of the deformed layer () in which the furrows are formed between the channels, prior to the assembly of the alveolar structure.
