Shevlin Hall, a historic building erected in 1906, is presently home to the department of Speech-Language-Hearing Sciences on the University of Minnesota campus. The primary classroom space is a 20' x 50' room with a high coffered ceiling used for lecture-style classes, discussion groups, and social events. The space underwent renovation in 2013 to address room acoustics and sound design. Post-renovation acoustic measurements and subjective responses reflect favorable outcomes for lecture conditions. Challenges remain for small-group and active discussion classroom arrangements. The current study evaluated predicted and measured speech intelligibility for small-group and active discussions. Preliminary data suggest good intelligibility throughout the room for the condition of lecture-style presentation. Reduced intelligibility is suggested for the condition of talker in back and receiver at instructor or front center position. Implications for sound design will be discussed.
