Scientists at New York's Columbia University have developed a mind-controlled hearing aid, which focuses on specific voices in a busy room, solving what is known as the "cocktail party effect
Noises generated in the space, like the squeak of a cart wheel or the step of a foot, bounce off hard surfaces and force people in the space to speak louder in order to be heard over the noise, resulting in what's often called the "cocktail party effect
This is the reason cocktail party effect in audio steganography has been explored to ensure enhanced security during data transmission.
In , it has been stated that cocktail party effect can be explained by Binaural Masking Level Difference (BMLD).
However, as blind steganographic approach is considered more robust and secure than the nonblind steganography techniques, hence, in this proposed method, "Blind Source Separation" approach has been chosen for solving cocktail party effect.
Psychologists have known for decades about the so-called "cocktail party effect
," a name that evokes the Mad Men era in which it was coined.
Such distortions are thought to account for some of the difficulty that people with hearing loss have in separating conversations in the presence of background noise--the so-called "cocktail party effect
." A common complaint among victims of hearing loss is that "I can hear the sound but can't understand the words." Simply turning up the volume won't solve that problem.
Cardiff University's Dr John Culling, who has been studying the so-called, 'cocktail party effect
,' says brains and ears work overtime to pick up interesting sounds at scenarios like loud parties.
In the "cocktail party effect
," people who have normal hearing in two ears have an easier time engaging in conversation in a room where other people talking, compared with people who have any hearing loss.
"Our everyday ability to listen to one desired voice out of a collection of different voices is known as the 'cocktail party effect
,' which depends on two-ear listening to separate the sounds in space," explains Begault.
The screening of auditory information is called the "cocktail party effect
"-- in a noisy room you can screen out all conversations except the one in which you are participating.
Washington, Dec 1 (ANI): Using 'virtual ears', researchers at Oxford University have uncovered the mechanism behind what is known as 'cocktail party effect
