I have never studied this topic in any formal fashion. My own (mild, high-frequency) tinnitus becomes noticeable only when I listen to music live, or on high-quality audio. This and further observation suggests that (in particular) your auditory channel is equipped with a sophisticated filter / Fourier analyser which detects when a particular frequency band is missing from the input, and increases its sensitivity to compensate. Paradoxically then, if for some reason you have developed narrow-band deafness to that frequency, the sensitivity may become cranked up to the point where it is reproducing random noise --- maybe even (positive) feedback, in some sense?

Tinnitus is a supposedly rather common condition which was devastating to me when I developed it. Yes, one can and does learn to ignore it but it’s unquestionably the elephant in the room.

First time I recall the canceling-out Fred speaks of is noticing that a new refrigerator motor in my family home was quite audible at first, but over time became imperceptible. Until the thermostat would turn it off — at which moment someone might say, sincerely, "What was that?!"
When I was away at college my parents moved to another town nearby. My first time home it was quite noticeable that a plane would fly overhead every 6 minutes. Pretty soon, whenever I was there, the planes became imperceptible — unless I thought about them, in which case they were suddenly there.
