No matter what you do, your ears are always working. They are constantly detecting, deciphering and analysing sounds and communicating them to the brain. In a comparatively tiny area of our body the ear is performing many highly technical and intricate functions. Consider just a few of them:
(1) The human ear can cope with an incredible range of sound. Your ear can, in fact, cope with a 10,000,000,000,000 fold difference in loudness. That’s a range of 130 decibels.
(2) The ear can pick out and focus in on a particular sound or conversation in a roomful of noise.
(3) The human ear can detect a difference of just two degrees in the direction of a sound source.
(4) The ear is able to recognise at least 400,000 different sounds, matching them up against those stored in the memory banks. What we see of the ear is just the outer part of a very complex structure.
Scientists cannot fully explain just how the signals are transmitted to the brain. They do know that the signals sent by all the hair cells are about the same in duration and strength. This has led them to believe that it is not the content of the signals but rather the signals themselves that convey some sort of message to the brain.
Our ears, so often taken for granted, thus are a marvel of intricacy and design that leaves anything that man can produce in the shade as a cheap imitation. Your hearing can never be replaced. Don’t take it for granted.
