My doctor said that I cannot use earplugs anywhere (even at the school canteen). He also said that I have to go to the trip where I have a 10 hour flight.
I have MRI tomorrow. I don't know if he will let me use earplugs.
Everyone (almost) here have told me to use earplugs in loud environments, which I have followed. Now my doctor says something like this? Is he out of her mind, or should I really just stop protecting my hearing and expose myself to loud sounds?
I've also gotten different opinions from different ENT's, GP's, psychiatrists and others regarding when to wear earplugs and if I still could go to concerts, etc. Most of them happily said that I should do anything (use the blender, vacuum cleaner, long car rides) without earplugs, except going to concerts, which should be absolutely fine with earplugs. It was nice to hear at first, but I knew it was too good to be true. I'm not sure if some of these people are actually knowledgeable on tinnitus
or live music.
The tinnitus specialists from the hospital, which I consider to be the most knowledgeable, said not to use earplugs for everyday sounds (which indeed can lead to hyperacusis), but that going to concerts is a "maybe, you'd have to try it". This is what I found to be true. In other words, some situations may require you to wear earplugs or aren't safe even with earplugs.
Just use earplugs if you think it's necessary. There's no point in hearing uncomfortably loud sounds because someone told you that you should. As long as you don't wear earplugs 24/7 and do get to hear sounds in the 0 to 80 dB range (just about) regularly, you should be fine. There's certainly no harm in wearing earplugs for an MRI scan you'll only do once or twice. I doubt if wearing earplugs in the canteen for one or two hours a day can do any harm.
Canteens can be quite loud too! A couple of voices at normal speaking volume shouldn't be harmful, but a hundred of them all trying to be heard in the same room definitely can be.
If I'm not mistaken, if you do notice that you're getting hyperacusis from overprotection, this can be reversed. Hearing damage cannot be reversed. So even from this perspective, you'll be on the safer side wearing earplugs.
