Auditorium Acoustics

The room in which we listen to sound has an important influence on what we hear. This section will identify some of the principal means currently available for judging the quality of an auditorium. While we have a variety of methods and criteria for the evaluation of an existing acoustic space, the design of such a space from a specified characteristic is still relatively difficult.
