External ear structure that helps to localize the direction from which sound arises

Step2247 [10]

The external ear structure is called the Pinna.

The Pinna helps to channel sound waves into the ear.

I have attached an image of a dog's ear to show you the external structure called the Pinna.

I hope this helps! I'm happy to answer any other questions you might have :)
