Is it possible for this to become permanent if you're exposed to the sound for long periods of time every day?
My tinnitus has recently started mimicking crickets and also the noise my PC makes, which aren't noises I can isolate myself from without straight up using earplugs or earmuffs to block them out. I've been trying to avoid doing that in my own room, but I'd really rather just have the one tone, thank you...
If it makes any difference, I also have hyperacusis.
