Preferred Electroacoustic Transfer Function in a Stadium

This project uses a large scale stadium electroacoustical system to investigate the preferred frequency response of sound at listener positions in a stadium that seats more than 80,000. In addition to answering this question, the more fundamental issue of how a transfer function can be measured and generalised in such a complex space is addressed. A listening test was held in the stadium, and a large number of electroacoustical measurements were performed.

This project is being undertaken by Scott Willsallen as a masters dissertation at the University of Sydney, with the cooperation of Telstra Stadium and the Rugby Union World Cup 2003.
