Love hate relationship with AVS, hate that it makes me buy things I never knew I needed/wanted, love running into interesting info. Have had tinnitus for some time (didn't know better when I was younger. Loud concerts, loud clubs and parties, firing a .357 snub with no hearing protection, a firecracker going off inches from my ear that had me thinking for 3-4 days that I was permanently deafened in my right ear etc.). Yeah, the tinnitus from hearing doesn't go away, the brain just sort of learns to tune it out, kind of the way the brain stops smelling something after you've been continually exposed to it for a while (like no longer noticing the stench of all the bat guano we were standing in after a few minutes prepping at the entrance before entering the cave).
Most days it's not bad, but every once in a while, my brain decides (consciously or unconsciously) to see if the ringing is still there, and then it gets annoying till something distracts me enough that the brain can go back to its regular programing of tuning it out. I DO however, happen to be in a situation where I must endure sleeping amongst some occasionally noisy housemates for several days of the week for work. Even though I always sleep with some form of white noise (I always have a fan going when I'm sleeping) AND wear 30db earplugs in the house with the housemates, I still get woken up.
It's weird, but when I was in high school, it generally took 3 alarm clocks placed in random spots around the room to wake me up, and they had to be the LOUD kind with the bells to wake me up, or I'd sleep right through them. I once slept through my dad's car rolling out the garage, down the slope of the driveway, smashing through the wrought iron gate and across the road where it rammed the neighbor's car into a ditch (dog chewed through the parking brake cable and as the car warmed up while my dad was having breakfast, I guess the vibrations got it rolling out the garage and down the slope). I didn't even know all this occurred (my bedroom was in front of the house where all this occurred) till my mom asked me about it later that night. The year after I graduated HS though, I somehow transitioned from being a VERY heavy sleeper, to becoming a light enough sleeper that virtually every sound woke me up, so now I always have some kind of white noise to mask softer sounds.
Gonna try that noise generator to see if I can kill 2 birds with one stone, get some sounder sleep AND maybe reduce the effects of the tinnitus.
