With its 128-foot-wide, unsupported concrete dome springing 125 feet above the floor of its quarter-circle plan, the original 5300-seat mother church of the International Church of the Foursquare Gospel in Los Angeles (circa 1923) required adaptive reuse as a rock-n-praise Christian church. Challenges included squelching its 7-s RT60, decoupling the dome by eliminating its unusually severe focusing (largely responsible for repetitive echoes), especially strong at the intended audio mix position and stage, integrating acoustical and audio systems design to achieve 118 dBA uniformly throughout, while meeting full operation for opening services within 7 months. Because of its structurally weak dome and its National Register status, the principal acoustical solution prohibited covering, or supporting anything from, the focusing dome. Described is a method not known to have been applied elsewhere intervening about 95% of all the problematic, focusing sound rays with large suspended baffle/absorber panels specifically designed and positioned via laser model studies while achieving an attractive, dramatic array. The result is remarkably successful with respect to all intended acoustical, audio, and historical architecture goals.
