    Abstract: A hybrid acoustic absorption and reflection resonator can includes a rigid structure defining a cell, a membrane with at least one orifice attached to the rigid structure, and a back sheet attached to the rigid structure and covering the cell. The membrane is configured to reflect acoustic waves in a predetermined range of frequencies. The rigid structure, the membrane, and the back sheet define a Helmholtz cavity; the Helmholtz cavity is configured to absorb acoustic energy at a frequency within the predetermined range of frequencies.

    Abstract: An acoustic barrier structure can include a support structure that defines a plurality of cells, a weight attached to the support structure, and at least one resonant membrane covering one of the plurality of cells. The at least one resonant membrane can comprise at least one weight. The at least one resonant membrane can have an anti-resonant frequency and the support structure with the weight can provide wide frequency band gaps between odd resonance modes while suppressing structure-membrane coupled modes to enable the anti-resonance of the at least one resonant membrane.
