An acoustic insulation product includes a panel made of porous material, based on foam or fibres, including a first face, referred to as back face, intended to face towards a wall, and a second face, referred to as front face, situated on the opposite side to the back face, and a layer, referred to as backing layer, which adheres to or is linked or coupled at least in part to the back face of the panel made of porous material, the backing layer having an airflow resistance of between 5 kPa&#xb7;s/m and 20 kPa&#xb7;s/m.
