Abstract (en)
[origin: WO2014102473A1] The invention relates to an acoustic absorbent assembly (10) used to form a wall element inside a building, that can be fixed to at least one wall in order to form false walls, comprising two parallel fabrics (11, 12) that are assembled on the periphery on an attachment means, said fabrics (11, 12) respectively defining an inner fabric (12) and an outer fabric (11) when the assembly is fixed to the wall, one of the fabrics (12, 11) being free of perforations, the acoustic absorbent assembly (109 being characterised in that the outer fabric (11) is arranged at a determined distance from the inner fabric (12) and comprises micro-perforations (2) arranged so as to form an acoustic fabric.
