We all know that dogs can hear better than us. Try sneaking up on them and you'll find how difficult it is unless they're distracted, or there is another noise in the distance. This fantastic hearing isn't merely because their ears are more sensitive. There is another mechanism that makes a dog able to not only detect sounds, but also figure out where they're coming from.

Dog



Humans are notoriously bad at figuring out the location of sounds. We are easily distracted by sight first and sound later. Dogs however, have ears that move around or swivel as most of you might has seen. This movement acts as a sort of radar that allows the dog to display a comprehensive awareness of the source of sounds.

Of course, the time in which this happens is also important. In the case of humans, our typical reaction time is 2/3rds of a second. A dog however, can locate the source of a sound in as little as 6/100ths of a second! A remarkable ability and just another reminder of how talented our furry friends are.
