1. A tuned liquid damper comprising:
an outer housing having two ends, the first end being open to the atmosphere and the second end being a sealed, gas-filled chamber within the outer housing;
a separator attached to an inner perimeter wall of the chamber, the separator defining first and second partitions within the chamber and having an opening which allows gas to flow between the first and second partitions;
first and second membranes, each attached to the inside of the outer housing; and
a sealed compartment within the outer housing, defined by the first and second membranes and being at least partially filled with a liquid, which prevents gas flow through the outer housing from the first end to the second end.
