Abstract:
An acoustic structure comprising comprises a layer of material having a first Young's modulus called the intrinsic modulus and a first density called the intrinsic density, characterized in that the layer comprises at least one first zone having said first Young's modulus and said first density and at least one second zone buried in the volume of said layer of material and having a second Young's modulus and/or a second density obtained by implanting and/or by diffusing atoms into the volume of said layer.
