Abstract
The aim of the invention is to improve acoustic insulation panels of the prior art by proposing a rigid, light panel, the acoustical absorption performance of which is improved thanks to the use of a grid the structure of which enables the same to contribute to the noise absorption function. To this end, the present invention relates to an acoustic insulation panel including two facing panels (), separated by a solid structure () that is substantially planar and has two surfaces () that are substantially planar and parallel, each of which are rigidly connected to a facing panel, said structure () including through-holes () that form a mesh, such that the meshed structure contributes to the noise absorption function.
