Abstract

A novel type of acoustic liner, characterized through the utilization of specific composite materials with tailored intrinsic damping, is investigated with regard to broadening of the effective frequency range. Acoustic wind tunnel tests demonstrated the capability of some materials to broadening or to shift the effective frequency range to lower frequencies.
