The prediction of room acoustic measures using computer models is now a standard procedure with most acoustic consultants. The next logical step from predicting measures is to allow people to listen to the acoustical conditions in a planned hall - so-called auralization. The increased performance of computers and digital audio equipment has made it possible to create an auralization of a proposed hall within reasonable time and economic limits. This paper reports on some demonstrations of realistic room acoustic phenomena using computer models based on actual acoustic spaces and also on some more idealized rooms. The object has been to introduce the technique to and get response from acousticians as well as those who would benefit from it the most in the long run - the musicians and the concert-goers.
