The Qatar Univ. Sports & Events Complex consisting of Multi-purpose Hall and Training Hall was completed in November 2019. In addition to sports events, various 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 were still required to provide an exciting crowd experience during sports events, and thus the Active Field Control System (AFC) which is one of acoustic enhancement systems, was adopted to enhance loudness and liveness. This paper presents an overview of that system and the benefits achieved by its introduction.
