Tinnitus and Hyperacusis
Hearing loss often triggers an in escapable buzz (tinnitus) and causes everyday sounds to become intolerably loud (hyperacusis), but exactly where and how this occurs in the brain is unknown.
Your ears detect sounds as vibrations. If you have hyperacusis, your brain confuses or exaggerates certain vibrations. So even if you get the same signals as someone else, your brain reacts differently to them. That’s what causes the discomfort.
As many as 63 percent of tinnitus patients also suffer from hyperacusis.
