I was with you until: "[...] but it can also be heard by the examiner (eg, by placing a stethoscope over the patient's external auditory canal)." and now I'm even more confused

Poorly shielded electronic devices go BRRRRRRRRRRRRRRRRRRRRRRRRRRT EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE!

About 2/3 of my family (including me) have the same thing, some kind of hereditary issue with the nerve that runs from the jaw up behind the ear. Accompanied by most of us also having jaws that don't quite fit in their sockets properly and tend to pop and crunch from time to time.

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.

Somebody much smarter than me will be able provide answers!

The hair cell's whole job is to send neuronal signal when there's vibration at its specific frequency. It's entirely conceivable that a cell would get stuck in the ‘send signal’ mode when damaged, just as it can go the other way and send no signal ever anymore.

I spent 20 years trying to find a rheumatologist who would take my positive lupus test results, symptoms, extensive family history, and potential comorbidities seriously and give me a diagnosis and treatment. Nobody would listen until I was 23 because I was "too young." After 23, they started accusing me of just wanting medical marijuana.

At 27 I finally found a doctor that would take me seriously. We spent 2 hours going over the 15 years of medical records of mine that are accessible digitally, as well as some physical records from before that that my mother kept in a safe. The doctor ordered an absurd amount of tests and gave me a diagnosis when they all came back indicating that I, indeed, have lupus. She saw the same results in all of my records, too. I've tested positive and have had all of the other indicators my entire life. Like I am a textbook case of Systemic Lupus Erythematous that attacks the joints and connective tissue.

She started me on treatment and for the first time in my life, I'm not ruled by my pain and fatigue. I actually have a life now. I have started doing things that I've always dreamed of doing because now I can. I'm not chained to my bed anymore.

All of the doctors that refused to treat me despite positive test results and symptoms because I was "too young" or "just wanting marijuana" can rot in Hell. "Do not harm" my ass. I spent twenty years suffering, with multiple pediatricians and general practitioners sending me to every rheumatologist they knew of to try to get treatment for what they, non-specialists, believe I suffer from.

I drive two and a half hours one way every 6 months to see my rheumatologist and it's worth it because she gave me my life. I'd say she gave my life back to me, but I never had one to begin with. I'm actually living now. 20 years too late if you ask me, but better late than never.

To be fair, did she even try yoga?

Holy shit mine too! Mines much higher pitch but it was also briefly relieved. Ima keep that video in my pocket..

I wonder if there’s a way to tune that to match and negate an individual’s sound waves…

It's always there, but that doesn't mean one constantly hears it. I'm listening to music a lot, so then I don't hear it. When I skateboard or do any other sports I don't hear it, et cetera. Only when it's quiet I sometimes become aware of it, but because of habituation I usually unconsciously ignore it just as quickly. It does happen that sometimes in bed I keep focusing on it to the point it annoys me, but fortunately that's rare. Not being able to experience absolute silence in a forest anymore disappoints me though; c'est la vie.

That being said, I'm probably in the camp of people whose condition is mild. It must indeed be horrible for people whose tinnitus overpowers all other sounds.

now we're onto something. shoot that tinnitus dead with high frequency sound lasers

Tinnitus is typically induced by exposure to loud noise in the first place, so your proposal could as well make it worse.

Makes it worse from my experience. Tends to deaden everything but the squeal

tinnitus

Nice!

😅

I saw it but I thought it was a link for the source for the tweet not the source for the original article. I wasn't motivated enough to check it because of my assumption.

Its literally sounds that other people can’t hear because they are generated by your own ear ears. Typically, it’s from something damaged in your ear or excess earwax.

It’s not constant, necessarily. It’s also not always ringing. And, you might not hear it in both ears.

For me, I do hear ringing often but not constantly. Sometimes, I just hear a high pitched squeal for a bit. Sometimes it’s the unlike 30 seconds and sometimes it’s much longer.

The symptom that stands out most, is the static sound. It’s like the sound you hear when you tune a tv or a radio to empty station. It mostly happens if the environment is too loud. That could be loud music/tv, a crowd of people, or maybe even just someone speaking loudly.

Most of the time, it’s just kinda annoying and not too bad. If I hear static, I know I’m in an environment that is too loud, and I need to do something to protect the hearing I still have.

Ground loop feedback

Yeah you can hear tinnitus. Is it a different type?
