The Oregon Tinnitus and Hyperacusis Treatment Clinic opened its doors in 1997 to serve people from all over the world who suffer from these conditions. We have a focus on hyperacusis in our clinic, including direct patient care, medical provider education, and clinical research.

Our founder and director, Dr. Marsha Johnson, is an audiologist with extensive training and experience with hyperacusis.  She has published several articles on the topic, and created the widely used Johnson's Hyperacusis Quotient to measure and categorize severity and treatment outcomes for patients. 

In 2007, Dr. Johnson began to write a volume called The Companion's Guide To Tinnitus & Hyperacusis.  She is actively seeking interviews to help with the completion of real-life experiences portion of the book. Please contact her by email: [email protected]

Dr. Johnson completed her doctoral degree in Audiology in the summer of 2007.  She also includes here a recent article on head injury and hyperacusis.

Please feel free to email us with your questions and concerns.  We will be happy to help you in any way possible. No one should have to feel alone and unable to find answers.  503 234 1221 (Phone).
