University of South Dakota, Bailey & Kathy Aalfs Auditorium at Slagle Hall

One of the largest assembly halls in the area when constructed in the 1920s, the building once hosted a variety of major events but now primarily serves orchestral, wind, jazz, and choral ensembles associated with the University and the community. The room also houses an historic E.M. Skinner pipe organ, one of the few remaining examples of his work that remains in an unaltered condition. A new orchestra shell and stage extension accommodates the increased size of modern ensembles. Ceiling panels, integrated within plaster coffers overhead, function in conjunction with new lower gallery rails and new upper side walls to control echoes and provide much-needed acoustic support. Diffusive shaping at all upper walls reduces echoes and flutter while improving bass response.
