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.

Acoustical Systems is not a material manufacturer or manufacturer’s representative. We use and recommend acoustical material based on each specifice 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.
