Abstract (en)
[origin: WO2013050694A1] The invention relates to an acoustic attenuation panel (100) which includes the following main elements: a resistive skin (110) having acoustic holes; a solid skin (120); an acoustic structure (130) including a sound-absorbing material and arranged between the resistive skin (110) and the solid skin (120), characterised in that the solid skin (120) is structural and is configured in order to form at least one transverse spacer (121, 122) between the solid skin (120) and the resistive skin (110) of the acoustic attenuation panel (100).
