Abstract
A conventional honeycomb structure is strengthened by intermediate membranes (13), which compartmentalize the cells (5) in the height-wise direction. Such a structure more particularly has an increased mechanical strength and high damping properties for Helmholtz resonators intended to trap sound waves arriving on the structure by a perforated face (1).
