What happens when we hear a sound?
An object like a violin vibrates the air, and those vibrations travel from the violin through the air until they reach us. But we don't hear a violin with our noses or our elbows! These vibrations need to travel into our ears for us to really hear them.
So what is so special about our ears that allows us to hear sound? Well, the ear is naturally designed to collect, focus, and transmit sounds through a tiny and efficient conveyance system called the auditory pathway.
