A vehicle panel includes two sidewalls and a resonator disposed between them on one of the cell walls. The resonator includes a network of cells, each cell defines an internal space to absorb and dissipate noise and vibrations within a specific frequency range. Certain cells or subsets of cells may be interconnected to define a larger internal cell space. An airgap between the resonator and one of the sidewalls may be partially or completely filled with dampening material to absorb high frequency noise. The dampening material may also provide thermal insulation.
