According to this morning’s Metro Mini Cosm column, it’s possible to ignore the noise of a city, and it’s all thanks to bats.
Scientists have found that neurons exist in bat brains, which tell some neurons to be quite, and others to ‘yell louder’.
This way, the bats are able to block out insignificant racket, and concentrate on what is the most important.
What will this mean for research into audio usage? How much of what we hear to we actually listen to?
