Ear plugs would be a terrible idea for pressure change protection.
The air trapped between the plug and the eardrum is at normal 14.7 pressure.
If the air in your throat suddenly drops dramatically below 14.7, your eardrum will rupture inward.
I do not think you make this stuff up.
I think you do not know what you are talking about.
What is physical mechanism related to air pressure that detaches a retina?
“The air trapped between the plug and the eardrum is at normal 14.7 pressure.”
14.7 lbs. is the pressure of air at sea level. The cabin pressure of an aircraft in cruise is the equivalent of being between 6000 to 8000 feet mean sea level.
A little knowledge can be dangerous as your post demonstrates. Earplanes are not regular earplugs they are devices specifically designed to mitigate cabin pressure. They are single use per flight. They work in tandem with an app and were recommended by the ear specialist who treated my wife.
