  • Acoustic panel having a variable acoustic characteristic
    Patent number: 7963362
    Abstract: An acoustic panel includes a reflective layer, at least one alveolar structure, and an acoustically resistive structure forming an aerodynamic surface of an aircraft on the surface of which at least one acoustic wave propagates along an axis of propagation (24), whereby at least one of the characteristics of the acoustic panel influences the impedance of the panel that varies along the axis of propagation of the at least one acoustic wave, characterized in that it includes at least one first zone A with a constant acoustic impedance that is juxtaposed along the axis of propagation of the at least one acoustic wave at a zone C at which at least one characteristic of the acoustic panel that influences the impedance gradually varies along the axis of propagation of the at least one acoustic wave, whereby the characteristic has a value without sudden variations from one zone to the next.
