How does it help to have two ears?

The obvious advantage is that twice the sound energy is sensed and interpreted. Just as importantly, it also allows us to determine the direction that the sound is coming from. Your brain can detect the time difference of the sound as it enters each ear. It then uses this information to identify the relative direction of the source.

Two eyes separated by a few inches or centimeters give us the ability to determine the distance of objects because we see a slightly different image in each eye. Our brain interprets each image allowing us to judge the distance between us and the object.

Our ears do much the same thing. Our brain uses the slightly different sound in each ear to determine direction and distance. Humans are not particularly good at using their ears. Sometimes we change the direction of our head to hear a sound better, trying to judge where it is coming from. We hear sound in stereo.
