Theme park design has been a major part of our work since the late 1970s. Beginning with the Epcot Energy Pavilion, we not only worked with Disney but also with other entertainment companies to help design and ultimately to provide electronics equipment for their themed attractions. This effort started in the United States and moved overseas with Tokyo Disneyland, Tokyo Seas, and Sanrio Puroland in Japan as well as other projects in Australia, Canada, Korea, and Spain.

Theme park sound systems offer interesting challenges in ensuring that the sound seems to come from the character speaking. Any show sound must be interruptible for emergency and other pages without disrupting the overall show synchronization. We developed techniques to quiet such diverse sources as ride vehicles, animatronic figures, charging mechanisms, and waterfalls. In addition, we originated new types of absorptive materials including absorptive rock work and murals as well as acoustically transparent materials for hiding loudspeakers. Today, many of these techniques have become standard items in the theme park design repertoire, allowing companies to develop the look they want to achieve without the intrusion of loudspeakers and other technical paraphernalia into the show sets.
