Tinnitus and Hearing: From Cochlea to Cortex

Tinnitus—the phantom ringing, buzzing, or hissing that affects millions. For those patients who suffer with this debilitating condition, it is frustrating to find any relief. For those clinicians trying to treat it, the causes are so multi-faceted, and the treatments seem to be lacking.  

Today we break down the physiology of hearing, what can go wrong in the auditory system, and the many potential causes of tinnitus, from noise exposure to neurological conditions. We also examine current treatment options, emerging therapies, and what the latest research says about finding relief. Whether you're a sufferer or just curious, this episode tunes into the facts behind the noise.
