We have two ears so that we can hear things from both sides – two angles. This gives us a better understanding of our surroundings as our brain can then accurately analyse where the sound is coming from in relation to our position. Also, ears are more prone to damage as they cannot withstand very loud sounds. Thus, if your ear was placed above your head, you would still hear sounds from all angles, but it could get injured easily and you would go deaf. Having two
ears also provides you with a stronger defence mechanism.
