Ear Balling
Ear balling is the inside of your ear. It’s like an eyeball but for sounds. It’s what lets you hear your mom yelling at you from the other side of the house.
'My ear balling is broken, so I can’t hear my teacher.'
'He has big ear balling and can hear the quietest whisper.'
'Her ear balling is full of wax and she can’t hear a thing.'
