Tinnitus affects 5-10 percent of people with CNS mechanisms largely unknown

Evidence

In other words, a decrease in audible sound due to increasing deafness prompts the brain first to amplify, then generate data to palliate this apparent lack. — George Michelsen Foy, Zero Decibels, 331 (#expands, via linked claim)

The consequence of a task-related design is that, by using a subtraction approach, the tinnitus-related activity, present in both conditions, will not be present in the subtraction image unless the task affects the perception of tinnitus (Lanting et al. 2009 ). — Dijk, Pim van, Physiology, Psychoacoustics and…, 2747 (#complicates, via linked claim)
