Having an ear on each side of our head also helps us to hear better. Dolphins, for example, can't hear sounds as low as we can, but can hear high sounds of over 100,000 Hz. Sounds are everywhere, and you have two cool parts on your body that let you hear them all: your ears! Lots of adults think that only kids have this particular 'problem'. Hearing depends on a series of complex steps that change sound waves in the air into electrical signals.
