      If you close your eyes tightly you can induce the perception of color. If you stand in a doorway and lift your arms to the side so that the backs of your hands are pressing against the inside of the door frame, keep pressing for 60 seconds, then step out of the doorway and relax your arms: it’ll feel like your arms are floating.

      The body’s systems are complex and part of reliably filtering signal from noise in such systems is establishing a baseline while in a steady state. Our brains are pretty good at filtering out noise but the pressures or degradations which lead to tinnitus seem to trick the brain into accepting some noise as signal.

      If you’re looking for a deep dive then the following paper does an excellent job of outling what we know and what our best guesses are so far: https://www.sciencedirect.com/science/article/abs/pii/S0306987724002718

      It’s jargon-laden but nothing someone armed with a dictionary can’t handle. 🙂

      Maybe it’s like the way microphones and speakers are basically the same hardware, with the cells surrounding the hair in your ear canal vibrating those hairs “out” at high frequency for some reason.
