InspecTech Aero Service has launched its iShade iQ electrically dimmable window, and the new technology includes a breakthrough in noise damping, according to the Fort Lauderdale, Fla.-based company. “Cabin windows are a main path for noise transmission,” explained the company at the Aircraft Interiors Expo in April in Hamburg, Germany. “The unique method of light control used in iShades enabled InspectTech to develop a solution to achieve a quieter cabin by using an eleven-layer sealed stack that performs as an unprecedented sound barrier.”
