The auditorium at Dunmore Junior/Senior High School was constructed in 1938 as a gymnasium. During a major renovation 1969, the space was converted to an auditorium. One end of the space was raised to create a stage, and a sloped ceiling structure was constructed and sprayed with an acoustic material. The side walls were built out to complement the “projecting” of COST PER SQ FT$53.56FEATURED IN2002 Educational InteriorsINTERIOR CATEGORYInterior Renovation ceiling, and seats were installed on the unsloped gymnasium floor.
By 1999, the fixtures and materials of the auditorium were well worn. Despite the acoustic treatment on the ceiling, reverberation time was too long for plays, and sightlines were poor because the floor lacked a rake.
The design intent for this project was to improve the acoustic performance and sightlines, while updating the room’s finishes and appearance. Although the project budget precluded the sloping of the floor, the new seats were installed in varying widths to establish better sightlines. A percentage of the side and rear walls were covered with acoustic panels. On the new ceiling, hard-surface “clouds” improved acoustic performance. A portion of the projected sound “leaks” past the clouds where it is trapped in the acoustic insulation on the substructure above. The result is improved voice projection and reduced reverberation time.
