Cocktail party effect

a listening experience

TRANSLATION

Cocktail party effect = Cocktailparty-Effekt, intelligentes oder selektives Hören —— ein Phänomen, bei dem das Gehirn in der Lage ist, die auditive Aufmerksamkeit auf einen bestimmten Reiz zu lenken und dabei eine Reihe anderer Reize auszublenden, wie z. B. wenn sich ein Partygänger in einem lauten Raum auf ein einziges Gespräch konzentrieren kann

STATISTICS

IN THE PRESS

“Scientists have been working for years to resolve this problem, known as the COCKTAIL PARTY EFFECT. The brain-controlled hearing aid appears to have cracked the problem using a combination of artificial intelligence and sensors designed to monitor the listener’s brain activity.”

Cocktail party effect
phrase

- the ability (or the difficulty) of focusing one’s attention on a single auditory source among a jumble of noises.

- a situation in which a person engrossed in conversation, nonetheless hears their name mentioned elsewhere in the hubbub of the party. This demonstrates our ability to unconsciously monitor the social environment for self-relevant cues.


ORIGIN

The effect was first defined and named “the cocktail party problem” by Colin Cherry in 1953. Cherry, a researcher at Imperial College, London, conducted a series of experiments in which participants listened to different messages from single and multiple loudspeakers at the same time, and tried to separate them.


AIR TRAFFIC CONTROL

This phenomenon first became relevant for air traffic control in the 1950s. Air traffic controllers received messages from many pilots simultaneously into a single loudspeaker and it was their job to mentally filter out the message that they needed in order to guide planes safely to landing.

The mechanism our brains use to filter aural information is very hard to mimic digitally. Neuroscientists, psychologists, and acousticians are still struggling to understand the puzzling implications of this phenomenon.


ONE-EAR LISTENING

Interestingly, if you muffle one of your ears at a cocktail party, it suddenly becomes very difficult to localise a sound source and focus on a single conversation.

SMUGGLE OWAD into today’s conversation, say something like:

“Next time you’re in a room with several conversations, test the COCKTAIL PARTY EFFECT by closing your eyes and muffling one of your ears.”
