Teri A. Hamill, PhD, is Professor of Audiology at Nova Southeastern University, where she teaches AuD students. Approaching her twentieth year as an academic, she has also worked in a hospital setting. Her special interest in and knowledge of instrumentation manifested in her post-doctorate in 1987-88 with Project Phoenix/Nicolet which, being ahead of its time, produced a commercially unsuccessful fully digital hearing aid. Her knowledge of digital signal processing is enhanced, she claims, through her marriage to a computer scientist. As her major professor in her doctoral studies, Dr. Price’s manuscript was well known to Dr. Hamill and she added to the text introductory material for all of the topics in hearing science: acoustics, speech perception, analog and digital instrumentation, and anatomy and physiology of both the auditory and vestibular systems, as well as psychoacoustics.
