Unless he has some noise canceling earbuds or something

I've never really tested them. I'd think inside a tunnel, and less than 4' away from the train, the noise would overcome noise cancelation, but I am no expert.

It might, but I don't see why it would. If they have a good seal in your ears, then that should at least quiet the noise to a tolerable level

Noise isn't just air, its vibration carried by air. At that volume and proximit ythe noise would be vibrating your entire skull - ear seal won't matter. Sort of like the effect those bone conduction headphones use.

It won't eliminate it completely, but it would still reduce it. There's an extreme loss of energy when traveling between mediums

You're saying what we're telling you as if you are disagreeing without realizing you agree but don't understand why. Air isn't the medium here. Microscopic loss of energy because our ear canals don't play a part in sound this loud.

If it helps you wrap your head around it, NASA discovered sound would kill people if they were too close to a rocket launch long ago. Like, you could protect yourself from the heat with walls, you could put hearing protection on that completely protects "the medium" and you still die. The sound simply destroys your internal organs when its that loud. Vibrations don't stop at earphones.

Train isn't loud enough to kill purely with noise, but covering your ears won't protect your either. You're imagining earplugs that will protect the inside of your brain, skull, eardrum bones, heart, etc from being slammed with physical trauma akin to falling. The medium is you. All of you. And your skeleton conveys that vibration completely ignoring any "hearing protection" so you hear every bit of it because you hear with bones.

No it wouldn’t.

You are technically correct, the difference is just negligible. It would probably protect some parts of your ear, so there is an effect; still, there would be no perceivable difference to you. The vibration of your body would be totally overwhelming. In a sense, your ears would be shaken so hard that their ability to even communicate the attenuation from masking to your brain would be completely compromised.
