Design of the acoustic enhancement system for crowd enhancement in the Qatar Univ. Sports & Events Complex

Document Thumbnail

The Qatar Univ. Sports & Events Complex, which includes a Multi-Purpose Hall and a Training Hall was completed in November 2019. In addition to sports events, various other kinds of events, including lectures and pop concerts, will be held at this venue. To realize high speech intelligibility of the PA system, the entire interior except the floor is covered with acoustically absorptive materials. However, the resulting highly absorptive spaces are still required to provide an exciting crowd experience during sports events, and thus the Active Field Control (AFC) system was adopted to enhance loudness and reverberance. This engineering brief gives an overview of that system and the benefits achieved by its introduction.
