A common symptom of traumatic brain injury is hypersensitivity to sound.
This is called hyperacusis. The auditory system becomes very sensitive to environmental noise, and you may discover that you have great difficulty going to restaurants, the grocery store, or social gatherings.
An excellent accommodation for hyperacusis is ear filters. The actual name is ER 15/25 noise-dampening ear filters. These are custom-fitted earplugs, originally made for musicians, but they now have been adapted for individuals with traumatic brain injuries. Consult an audiologist at a speech and hearing clinic to obtain filters.
