When you hear a sound it's because all the right components have come together. An object must vibrate in the air. A person must share the same air with that air must be continuous between the vibration and the person's ear. There can be no vacuum gaps.

Vibrations of different frequencies cause sound. Not all vibrations are heard as sound by humans. Some animals can hear sounds that humans can not hear.
