Case study: tinnitus with distortion

- rndn 11y agoIs it not possible to stimulate the vagus nerve at will, for example by coughing?
- gone35 11y agoInteresting; that's indeed an uncommon form of tinnitus. If you are curious, here are some simulated samples[1]. Make sure though you set the volume at a comfortable level first, and listen all of them to get a representative idea (the first half are noisy/low-frequency; the second half are of the high-pitched variety, like my own).

- nothrabannosir 11y agoOh my, that's horrifying. I have #9, but that is apparently very lucky. My thoughts go out to those who suffer from any of the first few.
- psykovsky 11y agoI can say the same about the #8 I suffer from.
- gone35 11y agoI think so too, but I guess it's relative: my younger sister suffers from the low-pitch/noisier variety, and she thinks having a constant high-pitch in your ear must be horrifying. She might be right, but I try not to think much about it.
- visarga 11y agoI have a mix of 75% no. "6" and 25% no. "9". It is loud enough that I can hear it while talking to people or walking on the street, but if I don't mind it or forget about it, I can go for days or months without hearing it. When I focus on it, it comes back shining. Recently, I am trying to be mindful of my inner sound in a similar way to breath mindfulness.
- paublyrne 11y agoI had/have a similar low frequency tinnitus that began in 2009 during a period of stress. It was so loud that it made it coloured every day sound including speech and music, and made sleeping a nightmare. I eventually worked out a correlation to muscle tension in the muscles in my shoulder on the same side as the effected ear. I worked a programme for muscle improvement through strengthening, stretching, and relaxation techniques, which alleviated noise almost completely, although occasionally I still get it a little, at a very low level.
- mattmanser 11y agoAny more detail? I have had quite variable tinnitus for three years now on one side and am beginning to suspect it's related to muscle tension in that shoulder.
- kungfufrog 11y agoI have the same thing. I'm almost certain the sound is associated with shoulder/jaw tension on my left side. I can raise the sound frequency by jutting my jaw forward. Quite often the ringing is worse after a day of sitting at work and typically reaches a veritable crescendo by Friday afternoon. Likewise the onset of my tinnitus correlates with a period of stress and long hours at work sitting down.
- dazc 11y agoYou should get this checked out as tinnitus in one side can be a symptom of acoustic neuroma. http://patient.info/health/acoustic-neuroma-leaflet http://patient.info/health/acoustic-neuroma-leaflet
- mattmanser 11y agoYeah, I've had an MRI and was told there was nothing obvious and to habituate it, which by then I already had. However it varies quite a lot and am beginning to notice it tends to be a lot worse when I'm stressed or my shoulders feel tense.
- EliRivers 11y agoThe author of this, Oona Räisänen, is one of my standard examples of someone who is genuinely a hacker in the proper (by which I mean, the Stephen Levy "Hackers" definition; if you want to use the prior MIT prankster meaning, I won't stop you) sense. This post of Oona's - http://www.windytan.com/2014/02/mystery-signal-from-helicopter.html http://www.windytan.com/2014/02/mystery-signal-from-helicopt... - in which she extracts, from the audio of footage from a news helicopter, the location of that helicopter, is an excellent example. Given that someone here recently defined "hacker" to me as "person who can write code", the word is in serious danger of being so devalued as to be useless.
- HOLYCOWBATMAN 11y agoIts the first blog i have bookmarked in years. I just couldnt stop reading all the previous posts. Every post is full of interesting content not just empty useless rants. This is quite the change from the typical wannabe philosopher blogs "durr web is broken." or "10 Things To Know When Making Web App in <yyyymmdd>" ...ok back to reading the rest of the posts!
- tim333 11y ago>My next plan was to use a small in-ear microphone setup to try and find out if there was an objective sound present. As someone with some tinnitus myself I've been tempted to try that. The usual explanation you see of tinnitus is that the sound sensors break and then the nervous system makes up sounds to compensate but that's never really made sense to me. Usually if you don't get input to the nervous system because say a limb goes numb or you lose sight you don't get that kind of effect. The ear seems to have a built in amplifier using positive feedback - the "cochlear amplifier is the outer hair cell which increases the amplitude and frequency selectivity of sound vibrations using electromechanical feedback."(Wikipedia). I wouldn't be surprised if that mechanism goes out of wack and makes a noise in the way that you can get a squealing feedback from a public address system when the gain is set too high. I'm not sure that's been experimentally tested in a way that makes if clear if that's a thing or not.
- windytan 11y agoThe sound is back so I did the experiment now, updates are there.
- tim333 11y agoThanks for posting. Googling elsewhere it seems only about 5% of tinnitus is objective as in being audible in a stethoscope or similar. Though it's remarkable how sensitive the ear is. Apparently at the threshold of human hearing the vibrations at the basilar membrane are of the order of 1/1000 of the width of an atom so I guess there could be stuff going on that you can't pick up with a microphone/stethoscope, perhaps. http://www.nobelprize.org/nobel_prizes/medicine/laureates/1961/bekesy-lecture.pdf http://www.nobelprize.org/nobel_prizes/medicine/laureates/19...
