What Causes Hyperacusis?

Head Trauma

After individuals experience a traumatic brain injury, it's relatively common to develop hyperacusis. The head trauma doesn't need to have been severe. In fact, the mildest and most common type of traumatic brain injury is a concussion. Patients recovering from concussions and more serious injuries might notice environmental sounds are extremely loud and impossible to filter. Many individuals have so much trouble with outside noises that they stay indoors. Any noise is liable to trigger hyperacusis symptoms, but normally-unnoticed noises like electrical humming are particularly susceptible to sensitivity. Hyperacusis patients can talk to audiologists about treatment options. Often, those with traumatic brain injuries can benefit from customized earplugs that dampen noise. Though these earplugs were first designed to protect musicians during loud concerts, they've been adapted for individuals with traumatic brain injuries.
