Causes of hyperacusis

Hyperacusis has been associated with:

  • tinnitus hearing sounds that come from inside your body, rather than from an outside source
  • hearing loss the brain may sometimes compensate for reduced hearing by amplifying signals coming from the ears
  • damage to the ear or brain including from a head injury , ear surgery, exposure to loud noise, earwax removal , glue ear , and persistent ear infections
  • migraines
  • Bell's palsy a type offacial paralysis
  • Mnire's disease a disorder of the inner ear thatcauses a spinning sensation (vertigo) , tinnitus, andhearing loss
  • depression and post-traumatic stress disorder (PTSD)
  • Addison's disease a rare disorder of the adrenal glands, which sit near the kidneys and produce important hormones
  • disorders affecting the brain such asWilliams' syndrome or autism spectrum disorder

Hyperacusis can also be a side effect of certain medications. If you're taking any medication, check the leaflet it comes withto see if hyperacusis is listed as a possible side effect.
