| Study | Contact | Hearing Loss | Normal Hearing | Tinnitus |
|---|---|---|---|---|
| NOISE Study This study collects information about military noise, hearing, tinnitus, and other health concerns to better understand the long-term effects of military noise exposure. Subjects: Veterans within 2.5 years of leaving active military service (DD-214) or the Guard/Reserves. |
Research Assistants: Sachyea: (503) 220-8262, ext. 55656 ShienPei: (503) 220-8262, ext. 57385 |

| Ototoxicity-associated Mutations Following Antiretroviral Exposure This study collects hearing and genetic information to better understand potential effects of antiretroviral medications used for HIV treatment and prevention. Subjects: Veterans aged 18-80, regardless of HIV status or hearing loss; non-Veterans who take medications for HIV treatment or prevention (PrEP). |
Research Audiologist: Hunter: (503) 220-8262, ext. 59683 | |||
| Developing Tools and Care Path for Somatosensory Tinnitus This research is studying somatosensory tinnitus (ringing, humming, buzzing noise in the ears or head). This type of tinnitus is suspected when the loudness and/or pitch changes with certain movements. This study has two parts: (1) Create a screening tool for somatosensory tinnitus and (2) perform a randomized clinical trial comparing different treatment approaches for somatosensory tinnitus. Subjects: Veterans, 18 years or older, with constant tinnitus. |
Research Assistant: Chan: (503) 220-8262, ext. 56651 | |||
| Mouse, Man, and Machine The purpose of this study is to develop a computer algorithm that can estimate the strength of the neural connections between the inner ear and the central auditory system in individual patients based on how they perform on several tests of auditory function. Subjects: Veterans and non-Veterans, 18 years or older, no history of a concussion, native English speaker, with normal hearing or a mild hearing loss. |
Research Audiologist: Haley: (503) 220-8262, ext. 53796 | |||
| Effects of Non-Blast mTBI on Binaural Processing and Speech Understanding in Noise This study examines how brain injury impacts sound processing. The long-term purpose of this research is to improve the measurement, diagnosis, and treatment of individuals’ abilities to understand speech in complex listening environments with background noise Subjects: Veterans and non-Veterans, normal hearing, history of concussion or mild TBI, 20-55 years of age, right-handed, native English speaker. |
