The present disclosure provides acoustic structures 118 and related systems and methods which may be used to dampen or attenuate sound waves, including, for example, noise generated by or emanating from various aspects or components of turbomachines such as turbine engines 100. These acoustic structures 118 include oblique polyhedral cellular structures 200, including converging polyhedral cells 212 and diverging polyhedral cells 214, and related systems and methods of making and using such acoustic structures.
