Translational Research IIIFrom Bench to Bedside: Approaches for Objective Measures and Treatment of Hearing and Balance Dysfunction Tinnitus affects more than 50 million Americans annually. This condition remains the number one most compensated disability benefit for military Veterans. The hissing and buzzing heard by tinnitus sufferers in the absence of an external sound source can be intermittent or chronic lasting from minutes to days. For some tinnitus is permanent. Loud persistent tinnitus is associated with anxiety and depression with suicide ideation. These symptoms result in more missed work days, isolation, and increased clinician visits. People who work in noisy environments, older adults, musicians, military personnel Veterans, factory workers, etc… are at higher risk for tinnitus. With advances of sound technology, recreational exposure to loud noise is on the rise, putting even more people at risk for tinnitus. Symptoms of tinnitus are often addressed with therapy, noise canceling sound generators, and hearing aids. However, there is currently no cure for noise induced tinnitus. Impediments to discovering a cure range from a lack of objective measures of tinnitus, no consensus on a standard experimental model or defined underlying mechanisms, and therefore no broadly effective treatments. Removal of each of these barriers is essential for application to the clinic and substantive progression towards a cure for tinnitus.
