The term “cocktail party effect” refers to the human ability to focus on a single speaker while turning out noisy background noise. Research indicates that the left side of our brain picks out the desired sounds from the background noise. This makes sense when you take into account that speech signals are processed in the left brain. When researchers monitored the brain’s response to different sound combinations, it was observed that the left hemisphere displayed the most neural activity associated with processing sounds in a noisy setting. While no one is suggesting that today’s highly sophisticated hearing instruments are on a par with the brain when it comes to picking out desired sounds in noisy environments, they do remarkably well.
P.S The more formal term for the ability to focus on a specific source amidst the din of a crowded room is “selective hearing”
