mwint commented on Tinnitus linked to undetected auditory nerve damage   scitechdaily.com/tinnitus... · Posted by u/beefman

I used to have tinnitus. I suppose I still technically do, but it appears much more rarely, and when it does, I can make it stop entirely in just a few seconds. So I'm basically "free" of it these days.

Two things I learned over the years:

1. Tinnitus seems related to dopaminergic neurotransmission (or faults thereof.)

I have ADHD, but I didn't know it until I was an adult. Growing up, I would often get episodes of tinnitus. After being medicated for ADHD, these episodes became much more rare, and also exclusively now only occur at the end of the day, when my meds are half worn-off already.

I've seen many journal papers correlating tinnitus to various dopaminergic dysfunctions. For example, people who develop tinnitus in old age are apparently also more likely to develop parkinsonism, and vice-versa.

If you've noticed that you're developing tinnitus, then you might want to raise the possibility with your GP that you could have some undiagnosed problem with dopamine. Get screened for ADHD if you haven't; get tested for Parkinson's if you're the right age; etc. If it turns out that you have one of these chronic diseases and didn't know it — well, treating it on its own will probably change your life, but it'll potentially also help your tinnitus!

2. However, tinnitus also seems related to some physical process in the ear.

I've learned that, when the high-pitched ringing starts in one ear, I can instantly stop it — not just push it into the background, but literally silence it like pressing "stop" on an alarm — by using my finger to essentially plunge my ear: putting my finger into my ear canal just deeply enough and then twisting, resulting in a pressure seal like in-ear earbuds try to achieve; and then lightly — but quickly — pushing and pulling the trapped air-pressure in and out inside the ear canal, using the finger. After doing this for about 30 seconds (during which the tinnitus won't seem to change), my eardrum and ear canal both begin to feel warm. Once that happens, I then unplug the finger from my ear. At the moment I do, the tinnitus stops.

Presumably, the "plunging" action is in turn flexing my eardrum inward and outward. Basically it's acting like high-amplitude 1Hz infrasound. I'm not sure what this does that helps, but it certainly does help, consistently.

(If you're wondering: I've also had otitis media before, so I know what the sensation of my eustachian tube being blocked with fluid/crud, creating a pressure imbalance of the middle ear, feels like; and what unplugging the eustachian tube + rebalancing that pressure feels like. This isn't that! It's entirely an interaction between my finger, my eardrum, and maybe the bones of the middle ear. My ears are currently 100% clear of detritus on either side of the eardrum according to a recent ENT visit — and yet this procedure still works.)

Whoa. Dude. That finger plunging thing works.

randomly distributed means they'll hit you and the window with the same likelihood as any other part of your car. with your logic, it doesn't matter what car you get. you get shot anyway...

30% of my body is above the door. 70% is behind it. My chances of getting shot went down 70%. This math is not hard.

Just anecdotal, but I always noticed people I knew that had tinnitus had a history of using a lot of over the counter pain medication
mwint · 2 years ago
fwiw, I have mild tinnitus and have never had anything stronger than child Tylenol syrup - and that maybe once every two years or so.

it's great cos people never shoot at windows
mwint · 2 years ago
You are, of course, trying to be sarcastic. However, the majority of people who shoot at cars are not trained marksmen. The majority of your body is indeed behind the door, not behind the window. Bullets from an untrained shooter are essentially randomly distributed.

In short, if I had to drive through Chicago at night, this is without a doubt one of the best consumer vehicles to do that in.

About…? By whom..?

Whatever it is, know that science as a whole is giant, diverse, and self correcting over the long term.

mwint · 2 years ago
Over time, yes. But over, say, three weeks, science can do a lot of damage to an economy before it self-corrects.

Despite some misleading pictures shared on social media, if you do an apples-to-apples comparison (e.g., a 1972 F-150 and a 2023 model with the same bed size), they are about the same length. The differences are vastly better driver safety and fuel economy.

Even the differences in height are often overplayed by making bad-faith comparisons: https://i0.wp.com/www.curbsideclassic.com/wp-content/uploads...

The main difference is that nowadays, there are more factory and aftermarket configuration options available, and people have more money, so you see more people driving heavy-duty trucks with 35,000 lbs towing capacity, which have big engines and thus are rather beefy. But conversely, you also see more people buying small trucks with "stub-length" (4-5 ft) beds.

It's interesting that you don't really have a market of mini-pickups that are seen in Japan, but that's probably partly a matter of weird fuel efficiency regulations, of import restrictions, and cultural factors (few people in the US want to be seen riding anything golf-cart-sized, and it's not exactly a guy-only thing.)

Wow, that picture is striking. It needs to be an automatic reply to about 10% of comments on the subject, both here and Reddit.

having a screen with a satnav is a must, to compare GOM miles remaining to miles remaining of route
mwint · 2 years ago
Yeah, but my phone on a vent mount works fine for that.

Usually on any trip that brushes up against usable range, I do the math kind of backwards. I know the distance for the trip, and know how much buffer I have. Then I just look at the trip distance elapsed, compared to the GOM, and if they are roughly 1:1 I know I’m trending well.

My 10 year old Leaf has satnav, mobile connection, can download rss feeds and speak them out loud, has cruise control.

All the config is via touchscreen: charging timers, climate timers, satnav, bluetooth, phone.

Has voice control, a mobile app

My 9 year old leaf is an S model and has none of that - it’s blissfully simple. Prefer it over the SL model also in the family.

Can you get a temporary one that is revocable later? (Not an OpenAI user myself, but that would seem to be a way to lower the risk to acceptable levels)

In what way is the content of your comment strengthened by waving about a PPL? It serves only the patronize. Excise it, what does it change? Similarly, assuming that most of the audience here, aviation knowledge or not is unaware that there are mountains with people.

Anyway, passenger cabins require 8,000 ft for normal operation, so it's a bit misleading to say there's no legal requirement. https://www.law.cornell.edu/cfr/text/14/25.841. (And yes, I know the difference between airworthiness and operations, still misleading). Also why I'd bet a good sum you're a PPL.

> I'd bet a good sum you're a PPL.

I'm not even in the US; you're barking up the wrong tree. I apologize for disclosing a relevant fact. Won't happen again. Thanks for the link to CFR25.
