ABSTRACT:
This invention relates to acoustic liners having a plurality of cavities defining Helmholtz resonators in which the adjacent cavities are asymmetrical causing a pressure imbalance across the coupling means (tube, slot or aperture) between these cavities in the frequency range of interest. Such liners are particularly useful in turbofan engine noise reduction applications where low frequencies are encountered.
