Answer 1

The part of the ear that helps in processing the hearing is inside the head. The outside ear helps to direct sound waves inside the ear and so the skin and nerves on the outside ear that gets cold are in a different spot than inside the ear where it is much warmer where the nerves and ear drums are sending signals to the brain.
