How are we able to focus on a particular person’s words and almost “drown out” other people around us?
In: Biology
One answer to this is biology: our brains learn to do this because it’s an important skill, and over the course of evolution, people with genes that made it easier for us to pick out a stick breaking in a jungle we’re more likely to survive.
The other answer would be more mathematical and about how we write software that does this. For example you can search for PCA or noise reduction.
