The average measured rt60 value before acoustical treatment for this gymnasium was 2.1 seconds. The rt60 design goal was identified to be between 1.4 to 1.6 seconds. The resulting recommendation was to add 2,300 Sabin’s to the Multipurpose Room. The predicted and actual results of the acoustical treatment was a reverberation time of 1.5 seconds.

Before treatment | 1.66 | 1.88 | 2.39 | 2.64 | 1.87 |
After treatment | 1.6 | 1.4 | 1.4 | 1.6 | 1.5 |
Acoustical Systems is not a material manufacturer or manufacturer’s representative. We use and recommend acoustical material based on each specific application. Each material manufacturer has unique products and not all products fit every application. For this specific project we used MBI Colorsonics Wall Panels and Cloud-Lite Acoustical Baffles.
The average measured rt60 value before acoustical treatment for this gymnasium was 3.03 seconds. The rt60 design goal was identified to be between 1.3 to 1.8 seconds. The resulting recommendation was to add 4,168 Sabin’s to the Gym. Due to cost restraints, available space, sprinkler locations, etc. 3,482 Sabin’s were actually installed. The predicted and actual results of the acoustical treatment was a reverberation time of 1.8 seconds.

The treatment plan undertaken by ASI in this project was to attenuate the reverberation noise (RT60 = 4.9 seconds) through implementation of sound absorptive baffles in the ceiling areas of the kennel space. Ceiling suspended 2′ by 4′ absorption baffles were applied to each space. The quantity and placement of the panels was designed to maximize the reduction in reverberation in each space. The absorption system is illustrated in the drawings and photographs below.
