St. Paul's Union Depot

Achieving Intelligibility in a Historic Transportation Depot
Recently restored to its original 1920's grandeur, St. Paul's Union Depot again serves as a center and hosts concerts, art shows and other events. During restoration, the depot's highly reverberant acoustics and widely varying noise levels presented significant challenges to the important goal of clear voice paging for passenger and natural sound reinforcement for its frequent public events.
