Anechoic Chamber (85 Hz.) + Special Conditioning Unit

A project for a Canadian Government agency which included removing and disposing of an old chamber constructed in the 1950's, providing new foundations, and replacing it with this modern steel panel constructed unit with a low velocity, high volume heating and air conditioning unit. A second sound door was installed in the opening from the control room to the area where the chamber is constructed.
