Dizzying Sounds (IMAGE)
Caption
University of Utah biomedical engineering professor Richard Rabbitt (left) and doctoral student Marta Iversen have discovered why certain people experience dizziness when they hear a particular sound, such as a musical tone. For patients with semicircular canal dehiscence, there is a pathological hole in the bone that the inner ear is encased in, and certain acoustic tones cause the inner ear fluid to pump. As a result, the ear sends an incorrect signal to the brain, causing dizziness and vertigo.
