Degrees: Ph.D., Audiology and Speech-Language Pathology, The University of Memphis School of Audiology and Speech-Language Pathology; M.A., Audiology and Speech-Language Pathology, Memphis State University; B.A., Sociology, Salisbury State University


Areas of Expertise

  • Pathophysiology of Auditory Disorders
  • Speech and Language Development for Children with Hearing Loss
  • Hearing Conservation
  • Diving Physiology

Professional Background and Research

Keith Wolgemuth joined the Department of Communicative Disorders in 2005 and has revised and updated undergraduate and graduate courses in audiology and aural rehabilitation/habilitation. Additionally, he initiated an Aural Rehabilitation Clinic for graduate students where auditory, speech and language therapies are provided to children with hearing loss.

He maintains and has published an active research program with his former employer, the U.S. Navy, in the area of hearing conservation for military divers and the use of otoacoustic emissions testing to help prevent occupational hearing loss. Dr. Wolgemuth also is co-authoring a textbook on auditory disorders.
