LPT: If you're trying to talk to someone in a noisy environment, like at a concert, holding down the tragus will allow you to shout over the noise without blowing out their ear

Pushing the tragus into the ear canal like a makeshift ear plug protects from enough sound to allow you to shout over the background noise without having to scream right into their unprotected ear hole, or stopping someone from blowing out your ears when trying to scream in your ear about some stupid shit that happened at work in the middle of a concert. It works amazingly well.

Please use discretion as to whether your relationship with that person would allow for unsolicited ear touching.
