ABSTRACT:
A description is given of a sandwich structure which comprises a core and outer layers arranged on both sides of the core, in which the core has core clearances which are dimensioned such that the acoustic behavior of the sandwich structure in the region of the core clearances corresponds to the acoustic behavior of a double wall, and at the same time the global acoustic behavior of the sandwich structure is retained.
