Robert L. Folmer, Ph.D.


Robert Folmer (folmerr@ohsu.edu" ) earned B.A. and M.A. degrees in biology from San Francisco State University. He received his Ph.D. in Speech and Hearing Science from the University of California, San Francisco. At U.C.S.F. he conducted numerous EEG and evoked potential studies and evaluations for the Departments of Psychiatry, Neurology, Otolaryngology, and Neurosurgery. In 1997 he joined the staff of the OHSU Tinnitus Clinic where he currently serves as Clinical Neurophysiologist and Assistant Professor of Otolaryngology. In addition to his duties evaluating and treating patients in the Tinnitus Clinic, Dr. Folmer also provides intraoperative neural monitoring during surgeries that involve the spinal cord or cranial nerves.

Research Interests

Behavioral and pharmacological factors related to tinnitus severity

Approximately 40 million Americans have chronic tinnitus. For 10 million of these people, tinnitus can be a severely debilitating condition. Many patients with severe tinnitus experience a vicious cycle of symptoms that exacerbate one another. Identifying and treating insomnia, anxiety and depression with medications and/or psychotherapy/counseling will reduce tinnitus severity for most patients. In order to develop increasingly effective treatment programs, we continue to study the relationships between tinnitus and psychosocial factors that contribute to its perceived severity.

Hearing conservation education

Most cases of chronic tinnitus are associated with some degree of hearing loss. One type of hearing loss that is preventable is noise-induced hearing loss (NIHL). One way to encourage people to protect their ears from excessive noise exposure is to educate them about hearing, hearing loss and hearing conservation. The Oregon Hearing Research Center in collaboration with the Multnomah Education Service District, the National Hearing Conservation Association, the Oregon Museum of Science and Industry, the American Tinnitus Association, the Veterans Administration National Center for Rehabilitative Auditory Research, and Oregon Health Sciences University, is developing hearing conservation curricula for children. Our goal is to bring hearing conservation education to every K-12 student in the state of Oregon on a continuing basis. We hope that this program will ultimately reduce the prevalence of noise-induced hearing loss among children and adults.
