Why do ears pop on high speed train?
Why do ears pop on high speed train? On a train Unlike the change in altitude on a plane making your ears pop, a train going through a tunnel causes all of the air in the tunnel to be squeezed in front of the train. This, in turn, causes higher air pressure in the carriages, causing you to feel the pressure change in your ears.
What is a drawback to high-speed trains?

Do earplugs help with altitude?
The Aero Filter regulates ear pressure to ease altitude changes, helping to relieve ear popping and pressure discomfort naturally and safely. Another manner by which these special airplane earplugs help is by lowering noise levels in the cabin, allowing the user to rest, thus helping combat the effects of jet lag.
