A composite panel assembly includes first and second elastic membranes and a structure. The structure has a first side mounted to the first elastic membrane and a second side mounted to the second elastic membrane. The structure includes a first honeycomb layer, a second honeycomb layer, and a plurality of necks. The first honeycomb layer has partition walls defining resonance cavities that are covered by the first elastic membrane along the first side. The second honeycomb layer has partition walls defining resonance cavities that are covered by the second elastic membrane along the second side. The necks are disposed between and connect the first and second honeycomb layers. Each neck defines a channel that is fluidly connected to a corresponding one of the resonance cavities of the first honeycomb layer and a corresponding one of the resonance cavities of the second honeycomb layer.
