How do animals that can turn their ears have an advantage?

How do ears move?

A group of muscles called the auriculares are responsible for this movement. This group includes: the auricularis anterior, which draws the ear up and forward; the auricularis superior, which raises it; and the auricularis posterior, which pulls it backwards. ... But, some people can't stop wiggling their ears.
