Abstract
Built for the 1962 Seattle World’s Fair as a symbol of humanity’s Space Age aspirations, the Seattle Space Needle is one of the most recognizable landmarks in North America. In September 2017, construction commenced for “The Century Project,” a renovation project designed to reveal the tower’s internal structure while expanding and improving its views. This presentation will discuss the acoustical design criteria for the two levels of all-glass, circular observation levels, as well as design approaches for reverberant sound control, sound isolation for key areas, and mechanical system noise control for a proposed fine dining restaurant at the “Loupe” level. The presentation will also include post-construction measurements and several photos during construction and at project completion.
