Cocktail party effect

Definition

The cocktail party effect refers to the ability of an individual to focus on a specific auditory stimulus, such as a single conversation, while filtering out a wide range of other noises and sounds in a crowded environment. This phenomenon highlights the brain's capacity for selective attention, allowing people to concentrate on relevant auditory information despite competing background sounds, which is essential in environments like theaters where sound design plays a crucial role in audience perception.
