A 3700‐seat, general purpose auditorium was included in the convention center for the City of Austin, Texas. The hall is designed with removable, upholstered seats on the main floor, with the hall opening out into the exhibition area so that the auditorium proper can be converted into a dining area for 5000 people. The acoustical problems in this type of all‐purpose design are discussed and measurements presented on the reverberation time, echo structure, and articulation in the building. Since the auditorium is also used as a concert hall, subjective remarks by various musicians using the building also will be presented. Some particular problems in the use of a large auditorium by Broadway theater casts will also be discussed.
