Protect Your Ears With Ear Plugs
Within today’s loud world of constant distraction, very few people stop to consider the means through which they translate all of this audible stimuli: the ears; and a lot fewer still take the proper safeguards to defend their ears when they really should, even using so basic as plugs to protect the ears. Obviously ear plugs sound like a ridiculous, not entirely vital precaution in most situations – and in a lot of instances, they aren’t required – but understanding the significance of your ears is key to protecting them.
Ears are certainly used for hearing and interpreting sound. Sound – which are waves of pressure traveling through a medium, whether it be air, water, or something else – is first “heard” when it is trapped by the external ear (which is the visible part on either side of our head, and what we first think when we think of “ears”). These pressure waves, or sound, are then filtered through the outer portions of the ear until they interact with the ear drum and inner ear (those parts of the organ found inside of your skull), where they stimulate hair cells, delivering nervous signals to the brain. These signals are then interpreted as sound. Yes protection equipment come in a variety of forms.
Because of to the physically miniscule and delicate nature of the ear, it is very susceptible to physically trauma, which can even be inflicted by the aggressive vibrations caused by excessive noise levels. Visualize a speaker system or a subwoofer: the way the speaker cones vibrate as they produce sound is related to the way the small bones and tissues of the inner ear vibrate as they are stimulated by sound. And just like a subwoofer or speaker can break under the stress of these vibrations at high volume, so too can the parts of the human ear. Sounds experienced at places like construction zones or rock concerts are very easily able to damage the ear over long periods of exposure. By simply blocking such sounds from entering the ear, ear plugs can prevent this.
Except for protecting your actual capacity to hear, the protection supplied by ear plugs also preserves another crucial function of the ears that is a lot less clear: one’s sense of balance. In fact, balance is one of the two principal reasons that mammals generally have two ears (the other is that two ears enable us to locate the source of sounds by localizing them, equivalent to the way two working eyeballs allow depth perception). Deep inside the internal ear are the organs responsible for determining one’s orientation to gravity, and a sense of equilibrium.
Small fluid filled sacks send nerve signals to the brain that interprets these signals to establish a sense of physical orientation against the background environment. Since the fluid inside these sacks is subject to the identical laws of gravity as the rest of the body, the brain can interpret their orientation the same way you could possibly if you observed a soda bottle half filled. Regardless of the angle you look at it, you can figure out a sense of up and down by seeing in which direction gravity pulls the remaining fluid inside the bottle .
