Center for Interactive Learning, Sinclair Community College, Dayton, Ohio · Many technically sophisticated teaching spaces are sandwiched into this state-of-the-art building. A four-story atrium provides the central circulation and links to other campus buildings. The Forum is a semi-circular, tiered, high-end lecture and presentation space. There are also high tech classrooms, teaching laboratories, lecture halls, and a recording studio complex. Ostergaard Acoustical Associates collaborated with the architects and engineers to develop solutions for the unique acoustical needs of each space type.
College Hall Restoration, University of Pennsylvania, Philadelphia, Pennsylvania · College Hall is the first building on the University of Pennsylvania campus. This consultation involved a major renovation/restoration of the grandest space in College Hall, Room 200, a two-story gothic vaulted room with stained glass windows. The program called for complete restoration while providing a new multi-media environment with excellent acoustics to serve many uses, including lectures and banquets. OAA developed architecturally appropriate details for integrating reverberation control finishes, noise control solutions for the new HVAC system, sound isolating methods for the new mechanical equipment room, and a new sound system with concealed loudspeakers.
New Law School Commons, University of Virginia, Charlottesville, Virginia · Ostergaard Acoustical Associates is frequently asked to consult on the acoustics of atrium-like spaces. These are unusual spaces that, in the absence of acoustical engineering, often have the look of the outdoors and the sound of a steel industrial building. In this case, the University had previous atrium reverberation problems and expressed concern that our acoustical experience be included. Our analysis of The Commons determined the extent of sound absorption needed for acoustical comfort, identified candidate materials compatible with the architectural concept, and recommended correct quantities and locations for optimum acoustical effect.
A similar project is the glass-enclosed courtyard for Harvard Medical School. It is normally used as a lounge and circulation space, but also serves as a large meeting space and an area for receptions. For the medical school atrium, we designed a distributed sound system as well as consulting on reverberation and HVAC noise control. Other law school projects include the University of Alabama and Rutgers University.
Acoustical Renovation, The Pavilion, Villanova University, Villanova, Pennsylvania · The Pavilion is Villanova’s largest spectator facility with 6500 seats. In addition to basketball games, it is used for graduation, special Masses, and pop concerts. Despite the installation of a new state-of-the-art sound system, program sound was not clear because of excessive reverberation. OAA carried out comprehensive acoustical testing and an acoustical analysis to determine the quality and placement of candidate materials for controlling the reverberation. Following implementation and confirming acoustical measurements, it is now feasible to have all of the desired programs supported by clear, intelligible sound.
