Annually, beginning in 2010 with a symposium in honor of Peter Dallos, the Knowles Hearing Center holds a one‐day symposium in the fall. The symposium is conceived to attract an audience of researchers and clinicians that extends beyond Northwestern University. A specific topic is chosen in order to appeal to top investigators and clinicians, worldwide, who are interested in that selected subject. The topic changes from year to year, so over its course the symposia will appeal to a diverse audience and not become repetitious.
