No need to buy those expensive noise cancelling earbuds or wearing those high priced Bluetooth headset that makes you look like an alien from out of space talking in a party by yourself, because according to Neuroscientist Sam Wang, coauthor of Welcome to Your Brain, there's a better way and most important is a cheapest way to hear better: cover the mouthpiece.
How-to Wiki from Wired (via Lifehacker) tells us why the simple trick will deliver: Off the phone, one reason you can carry on a conversation in loud places is because your brain separates sound spatially by analyzing subtle differences in the signal from each ear. It can distinguish between a single source -- like the voice of your dinner date -- and the surrounding cacophony. Your mobile messes with your head by funneling both the caller's voice and the room noise into one ear.
