I do have external spinning drives here on my desk... I should start looking farther and wider for the culprit. I really am not keen on getting rid of this equipment. No electron left behind.

It was barely audible, and the tinnitus subsided after replacing the drive. There’s subjective tinnitus, which originates within the neurologic system and is heard only by the affected person. And there’s objective tinnitus, which has an identifiable source and can be heard by others. Examples of the latter include a vascular hum, a carotid bruit, or one’s heartbeat, all of which may be heard externally in the case of a dehiscent jugular bulb or an aberrant carotid. These are often diagnosed by putting a stethoscope over the ear canal or high under the back of the mandible. Extraneous sound when near a specific hard drive is far more likely to be objective and to have originated in the drive than in a response of the listener’s neurologic system to it. The characteristics of the sound(s) are often a clue to the causes of tinnitus, regardless of its nature or source. If I heard a faint high pitched whining or similar sound when near a drive, especially in both ears, I’d suspect a mechanical problem like a bearing and ask others if they hear it too. I’d stick a mic against it, record a few seconds of activity, and look for adventitious levels in the spectrum display in Audacity or whatever you use. Link to comment
Popular Post charlesphoto Posted May 18, 2020 Popular Post Share Posted May 18, 2020 I've had really bad tinnitus for decades now, thanks to being a rock photographer. One learns to live with it, but it can be frustrating - sometimes I just give up trying to listen to music, esp late at night. There are lifestyle things that can make it worse - if my candida issue isn't under control and I'm off my no sugar diet, too much coffee, cannabis, not enough magnesium, stress, loud noise or music, esp music that isn't played on a refined sounding system (i.e. car radio), flying, and alas, headphones. I haven't been to specialists; honestly imo there's not much that can be done beyond diet and lifestyle mitigation, and even then it's something you may just have to live with.

Sadly, that’s true for most sufferers. But there are some causes of tinnitus that need treatment, so a thorough evaluation is needed before accepting it and living with it. Especially if it’s only in one ear, an otologic evaluation is truly necessary. Imaging (CT &/or MRI) may be needed as well, before accepting that no cause will be found. There’s a popular misconception that if tests are unrevealing, they were unnecessary. This is simply wrong. If history, exam, and appropriate audiologic tests suggest a reasonable probability of identifiable pathology, imaging is essential - and so is follow up for as long as the symptoms persist.

charlesphoto Posted May 18, 2020 Share Posted May 18, 2020 Yes, you are correct, esp if it's a sudden on come and in one ear only with no easily recognized trauma being done to them. Many years of hanging over monitors and next to PA's, and one My Bloody Valentine show in particular, and I know personally there's not much to be done in my case. But others will be different. I had a scare a couple weeks back that ended me up in the ER thinking I was having a heart attack. It wasn't, though symptoms scarily lingered until a few days ago when I gave up coffee and they've almost entirely disappeared (as well as the associated panic attacks). Still going for more tests though (stress echo tomorrow) as one can never be too sure.

I know, I always feel a little uncomfortable when people thank me for my time when all I did was baby sit some big ass bombs (nukes). Even so I always thank my fellow vets especially as there are fewer and fewer of us every year. Looking forward to hearing what the ENT has to say.

Audiophile Neuroscience Posted May 19, 2020 Share Posted May 19, 2020 13 hours ago, bluesman said: The normal human auditory system is most sensitive at 3500-4000 Hz. There’s a second slightly lower peak at about 13k that seems to represent the 3rd harmonic of the resonant frequency of the external ear canal. But in-ear phones plug the canal, which both raises that frequency to far above audibility (eliminating it as a contributor to SPL) and blocks transmission of ambient sound to the tympanic membrane. The major factor affecting SPL in the truncated canal remains the SPL at the transducer. All canal resonance is shifted upward and the contributions from the external ear are eliminated. I’ve never seen a study that measured this with in-the-canal transducers (which is what I assume is meant by inner earphones). http://hyperphysics.phy-astr.gsu.edu/hbase/Sound/maxsens.html Hi Bluesman importantly the quote was from the paper I attached so I offer it only as worth considering. They found impairment IIRC that 4000 Hz which would accord with other sources of where the human auditory system is most sensitive. As they say "especially at high frequencies for which our hearing system is most sensitive." Thanks for the info about ear canal resonances and why that would shift those frequencies up to inaudible. It was the the authors of that paper who claimed a 6dB rise in SPL using "inside earphones". I have no idea whether this has been verified but they do present empirical evidence to support that this type of listening causes more hearing damage. I also have mild tinnitus. On different forums many people report spikes in tinnitus after using headphones and only recommend listening with conventional speakers. This is anecdotal and hotly debated (what isn't hotly debated??). 🙂 Sound Minds Mind Sound Link to comment

But if the SPL were 6 dB higher at the same gain settings, you’d turn it down 6 dB to the level you prefer. Is there an audiophile so foolish as to leave the volume higher than desired because the equipment made it so? Please tell me there is not 😏 lucretius and The Computer Audiophile 2 Link to comment

Is there an audiophile so foolish as to leave the volume higher than desired because the equipment made it so? Please tell me there is not 😏 More to the point, you would not even know it was 6dB higher, as in higher than what. So yes, it is hard to know what the authors meant by this. As I mentioned my intuitive but non verified concern is that in-ear transducers transform the ear canal into a sealed piston and may couple sharp changes in SPL more aggressively to the tympanic membrane although overall SPLs may be the same.The authors quote losing protective air space but do not provide any explanation or evidence. Notwithstanding any speculation on the mechanism, their objective findings of greater hearing impairment at 4k stands but unsure whether such results have been reproducible.

Mine was really bad during and after the staph infection I had (septic arthritis in right shoulder). The months on IV antibiotics probably didn't help either. Thanks for the update. Consider the magnesium supplement. I don't think there is any danger with that but you would know best Doc. AudioDoctor 1 Link to comment
bobbmd Posted May 21, 2020 Share Posted May 21, 2020 Glad to hear that(no pun intended) too bad about the MRI- hopefully the tinnitus will go away or lessen— did you ever think of cannabis the 1:1 cream THC to CBD rubbed on your ear lobe the vestibule and behind the ear maybe the tinnitus is an inflammatory reaction ( the extreme would be the tincture in the ear canal) in either case it would make listening to the DEAD more enjoyable AudioDoctor 1 Link to comment

Chris I am basing this on my own experience with Tinnitus, which the OP already has due to exposure to Occupation related high level sound exposure. I am not suggesting that this should be a problem for those not suffering from Tinnitus. However, very clean sounding Audio on headphones may sometimes result in extended listening sessions at higher than desirable levels without some kind of SPL guide.
