The need for a woven screen or mesh is eliminated in composite acoustic liners by providing an absorptive acoustic liner in which the perforated facesheet has a coating of an erosion-resistant material applied thereto. The coating can be applied using a simple spraying process. The acoustic liner can be easily tuned by regulating the thickness of the coating.

Le besoin d'un écran tissé ou d'une maille est éliminé dans les revêtements insonorisants composites en assurant un revêtement insonorisant absorbant dans lequel la tôle de surface perforé est couverte d'un revêtement à base d'un matériau résistant à l'érosion. Le revêtement peut être appliqué au moyen d'un simple processus de pulvérisation. Le revêtement insonorisant peut être facilement syntonisé par la régulation de l'épaisseur du revêtement.
