Hmm well I'm no medical or ear specialist but a few ideas. Maybe your ears have a lot of wax build-up. Depending on where the wax is, it can lead to odd things, from muffling to crackling to other noises. Ringing, I'm not so sure. But normally I get my ears flushed out once or twice a year at the doctor's office. You can do it at home too but I prefer to go to the doctors when I need it, since they know what they're doing and don't make a mess. Sometimes it really helps, other times it just makes me dizzy. But normally, if I wait until I can actually notice differences in my hearing, a flushing helps restore my hearing to a fresh state, and for a day or so, I'm marveling at how much brighter and direct everything sounds, as I get used to having clean ears again lol
But back to your problem. Something funny could be going on with your inner ear. Again, I can't say what, since a million reasons could be proposed. But I've gotten some pretty strange effects from my ears, so maybe one of these stories will at least be something you can relate to.
If it's dead quiet, I feel a lot of pressure in my head and a throbbing roaring or rumbling in my ears, it almost feels like I can hear the blood pressure through my temples or something. It's probably just tinitis or something, and I've had it for as long as I can remember. When I was like 4 or 5, it would get so bad that the room would start spinning and dematerializing, , causing me to fall in my dream. This would happen especially if I fell asleep while thinking about the pressure sensation I described. One thing's for sure, it's not a pleasant experience to spin and fall backwards in my dreams, and it wakes me up with a horrible start, and it almost always seems to be brought on by that pressure and roaring sensation. Thankfully, it only happens in dead quiet. When there's noise in the background, I don't experience any of this. So I find it more comfortable to sleep with the computer on, because it's just loud enough that I can hear it, but not loud enough to keep me awake.
Then there were other times when I would be in the pool for too long, and when I got out, certain ranges of notes would be very discordant and dissonant-sounding for some reason. I don't even remember being under the water that much, and I would get these odd effects for about a half hour after exiting the pool.
Then there were the times when I would get bad colds, ciness infections or whatever, and every time I would blow my nose, my ears would crackle and pop so loud that I was scared my eardrums would burst. One time it was so bad that I became dizzy when blowing my nose, and I almost fell. I was in the bathroom at the time which is full of hard things, so it would not have been fun to fall in there! So every time I feel like I have a bad cold coming on and I have to blow my nose, I always hold onto something while doing so. Thankfully, I've only needed to do this twice I believe.
Other than that, I really don't know what to suggest for you. If you continue to have odd issues, I'd see a doctor about it, especially if they get worse. But if you're just super picky about how your ears sound, and you notice occasional oddities that seem to clear up on their own, that don't seem to be progressively getting worse, I wouldn't get too worried.
Make more of less, that way you won't make less of more!
