Electroacoustic Enhancement Systems (EES) allow venues to vary their reverberant properties via electroacoustics and processing in order to appropriately support the type of performance presented, which can range from dramatic to symphonic. This is in contrast to the "traditional" method of establishing the basic reverberation time by providing the necessary room volume, and varying the T60 by moveable draperies, opening doors to chambers, etc. The challenge to successfully implementing an EES entails attaining a careful balance between a number of physical and acoustical variables. Currently there are several different system approaches to resolving these complex issues, each with its specific system architecture and implementation requirements. Our panel, comprised of representatives from each of the major EES manufacturers and led by a “non-aligned” acoustician, will discuss the history, topologies, system pros and cons, and the subtleties of designing and tuning these systems.
