Earphone deafness

Deafness to the outside world as a result of earphones inserted ears and music volume turned up very loud. People then underestimate how loud their burps, farts, breathing and yawning are, as theu have limited access to the outside world

"Megan, that was the loudest fart I have ever heard."
"Sorry, Kate, I had earphone deafness and didn't realise it was would be so loud."
