Fitness centers in mixed-use development: Examples from practice

Abstract

Spin classes utilize sound systems that generate levels in excess of 115 dBA, with subwoofers to match. Gyms located in office buildings feature Olympics style weight lifting technique that involves dropping 200 lb (or more) barbells from shoulder or overhead positions. Medicine balls get thrown at walls and floors. More “typical” sources of airborne and structureborne noise—treadmills, aerobics classes, weight machines, and the like—contribute to the din. The authors will present experiences and lessons learned from actual field experience with fitness centers located in commercial, residential, and mixed-use developments. Data will be presented on the effectiveness of mitigation methods installed in real buildings to attenuate airborne and structureborne noise. The session will include a discussion of the various types of fitness franchises and associated acoustic concerns, illustrated by case study examples from the authors’ acoustical consulting experience.
