You are at this fantastic and loud concert that you are enjoying too much and your friend beside you want's to tell you something but you are clueless because you can't hear him no matter what, what is the best way to get around the problem?

In general, any amount of loud shouts would be mumbo-jumbo to the next person beside you. Instead you can close your ear, the one nearer to the speaker, with one finger and easily listen to your buddy. Though this sounds counter intuitive, it generally works. The soundwaves travel through your finger better than through the air in loud situations.

Yeah, Science!
