Loud environments like concerts, clubs, and sporting events aren't well suited for conversations with your friends, but if you need to exchange a few words, try plugging your ears and speaking in a normal voice.

Osas Obaiza at WonderHowTo suggests sticking your fingers (gently) in your ears to help filter out the background music, and make it easier to focus what your friend is saying nearby. He also suggests having your conversation in a normal tone of voice, though you may need to speak directly into each others' ears. When you yell, your vocal frequency more closely matches the music in the background and begins to blend into it, but speaking normally helps your voice stand out among the noise. You might not be able to have a detailed discussion about last week's Game of Thrones, but these tricks should let you get a few ideas across in just about any environment.
