Hyperacusis affects over 240.0 million people globally (3.2% to 5.7% of adults) as 86.0% of patients suffer from chronic tinnitus, 34.0% experience physical nerve pain from sound (noxacusis), everyday sounds trigger distress at just 65 to 75 dB, and 48.0% of cases originate from acoustic trauma. While 28% of severe sufferers are housebound and 58% experience clinical depression, 54% improve through calibrated pink noise desensitization, though overprotecting with earplugs in quiet environments worsens auditory gain in 62% of patients. The figures below come from empirical clinical research published by the NIH, NIDCD, American Tinnitus Association, The Lancet, and Hyperacusis Research Ltd.
