Hyperacusis is an uncommon auditory condition characterized by an exaggerated sensitivity to sound. Individuals affected by this disorder perceive everyday sounds at normal volume as excruciatingly loud. Surprisingly, seemingly innocuous noises like the rustling of paper, clanging silverware, or the hum of a hairdryer can be as distressing to them as blaring sirens and honking horns. According to the Hyperacusis Network, approximately 1 in every 50,000 individuals experience this disorder either in one or both ears.
Recognizing Signs and Symptoms of Hyperacusis
Hyperacusis is characterized by an individual’s inability to tolerate common sounds encountered in everyday life. This condition manifests as an intense irritation and even pain, greatly impairing the affected person’s ability to engage in public activities. Individuals suffering from hyperacusis often resort to wearing earplugs outside of their homes or in situations where they have no control over the surrounding noise. Moreover, they may exhibit avoidance behavior towards social gatherings and develop a genuine fear of unpredictable loud sounds and noises.
Causes: Diseases and Disorders
Hyperacusis can be attributed to various diseases and disorders, as experts have identified several connections. These include Lyme disease, post-traumatic stress disorder (PTSD), Bell’s palsy, chronic fatigue syndrome, and autism. In fact, it is estimated that approximately 40% of children diagnosed with autism also experience hyperacusis. In addition, head trauma, severe inner ear infections, and even facial surgery have been known to trigger hyperacusis.
