We all know that humans have five main senses - sight, hearing, taste, smell and touch. Ears are important for animals because it is one of the sensory organs. Without it, we cannot sense any sound. Imagine this video on mute. Not fun, right?
But did you know that your ears help you walk? If you didn't, this is Now You Know and we will tell you how.
When anything makes a sound, the air pressure changes and our ears recognise those changes and tells the brain that it is a sound. Without ears, we will have a hard time communicating with other people or animals. We need both our ears to make out where a sound is coming from and from how far. We can't avoid moving cars or animals if our brain doesn't know in how long a sound source will reach us and that will be a safety risk.
It is also true that where there is a lot of noise like a concert, restaurant or a crosslane, having both ears help us in focussing on speech from the noise around it. We can never have a conversation in public otherwise.
Our ears have canals that detect three kinds of head movements - up and down, right and left and tilt and this helps us in maintaining balance. Without ears, we won't be able to sit upright, walk in a straight line or run without falling a lot. You must remember the dizziness you have felt after getting off a ferris wheel or after running in circles as a kid. Even after stopping, the fluid in your ear keeps moving because of Newton's 1st law of motion. When that stops, you feel the world rotating around you and this, with ears. Can you imagine not having them?
