They prescribe systemic steroids. Steroids reduce inflammation and might help recovery a little.

This comes up fairly often on tinnitus fora. Basically there is some "consensus" that a shot of steroids within a very short window, ideally less than 24 hours, can help. Unfortunately, the most common response to damaging one's hearing seems to be to sleep it off for a week and hope it gets better, making it difficult to conduct a study on early responses.

There are studies though, and my conclusion is that it's still mostly inconclusive. Still, if my tinnitus suddenly worsened id be down at the doctor's begging for the steroids.

I'm guessing an engineer named it the German equivalent of "pre-crash" sound, then someone in marketing decided that "pre-safe" sounds better. It may be better to call it "foreplay" sound, since if you ever hear it you're probably screwed.

Some technical disciplines use "safe" as a transitive verb meaning "to make it safe", either from damage or from damaging other things. I've seen it most often in rocketry contexts - you "safe the rocket" in an aborted launch scenario so it won't go off accidentally, etc. "It is a good idea to add a safety release valve to your launcher. Sometimes it is important to abort a launch and safe the rocket after it has bee…

I’ve taken up wearing earplugs while driving. I also work in a noisy environment, and it occurs to me that the road and engine and wind noise is probably loud enough to have a negative impact on hearing over time. Less so in newer cars, but both mine are over 10yo. Also, in the event of a collision I’m protected.

Wow, always putting earplugs in when you drive. Don't get me wrong, it is smart, just I lack the discipline to do it every time.

Well, it mostly involves leaving work with them in and leaving them in till I get where I'm going.

Plus, I've never been one to have ear infections, so I end up with used ones in all my pockets so they're pretty much always on me.

As another comment mentioned, there are flat frequency response ear plugs, Etymotic ETY ER20 are pretty cheap, reusable and cleanable. Not as much dB reduction, but that's better for some scenarios.

I just want to say that this is exactly the type of thoughtfulness, design, engineering and research that justifies the price difference in something like a Mercedes and something like a Honda. There are so many small triumphs like this in class-leading, high-end vehicle manufacturers that go unnoticed and unsung and allow people with 2019 Accords to say things like "why would I pay $45,000 for that when I get better auto-steering for half the price?".

Certainly there are subtleties to high end cars like road feel, steering, throttle feedback, and ergonomics that are only apparent to "car people" and thus work the premium versus something that is more "point A to point B". I applaud Mercedes for not only putting the effort into deploying a feature like this, but also for marketing it.

If I understand correctly some of the most common painkillers are steroids.

I might have seen Ibuprofen mentioned explicitly in relation with hearing loss.

Can anyone confirm or deny if taking Ibuprofen could help if one is stuck without a doctor?

Well, ibuprofen is certainly not a steroid - it is an NSAID (non-steroidal anti inflammatory drug)

There was a blogpost I read a few years back written by someone who damaged their hearing after dropping a porcelain toilet lid. They actually ran some back-of-the-envelope calculations to estimate the decibel level, I recall it being shockingly high.

To avoid confusion here, I think we are talking about ceramic cistern lids and not toilet bowl lids as the parent quote actually mentions.

The post starts off mentioning cistern lids, and the title mentions cistern lids, but lapses into toilet bowl lid about the time the parent starts quoting.

"2 I was fixing the mechanism inside the tank of the toilet. The only thing left to do was to put the ceramic lid back on the tank"

So guys, still no excuse for not putting the lid back down when you've finished ;)

At least in most of the usa, wearing earplugs (or earbuds, headphones, etc) while operating a car, is illegal. Please check with your local PD to be safe. You may just be putting yourself and others at higher risk by attinuating your situational awareness.

On the other hand driving schools in Europe sometimes make us drive with construction safety devices in order to check if we can drive without hearing anything. They also obstruct the middle mirror (you're supposed to be able to drive with just side mirrors).
