Among the professional sound systems used for the 1988 Winter Olympics were designs created for three highly reverberant indoor ice arenas. The systems were configured with medium-Q speakers in hybrid central-cluster and delayed-distributed speaker layout strategies. Advanced computer simulation programs were used to predict the performance of the systems in advance, both with respect to acoustics and array architecture. Room descriptions, design approach, performance predictions, array design, adjustment procedures, and measurement techniques are presented.
