Abstract
A multi-component acoustically resistive layer, for acoustical attenuating panels having a cellular core () flanked, on the sound wave arrival side, with an acoustically damping layer () and, on the opposite side, with a rear reflector (), comprises a first structural component () in contact with the aerodynamic flow and formed by at least one layer of fibers connected by a suitable resin and oriented in the direction of aerodynamic flow the component () comprising a suitable quantity of open surface; a dissipating component () disposed against the surface of the first component () opposite the flow, formed by a metallic cloth; and a second structural component () formed by at least one layer of fibers connected by a suitable resin, oriented orthogonally to the direction of aerodynamic flow. The second structural component () is connected to the cellular core () and comprises a suitable open surface quantity.
