Reasons Why Ear Plugs Have Their Role
Throughout today’s boisterous world of regular distraction, very few people stop to consider the means through which they translate all of this audible stimuli: the ears; and fewer still take the proper safeguards to protect their ears when they should, even using so simple as plugs for ears. Of course ear plugs sound like a ridiculous, not entirely needed precaution in most circumstances – and in a lot of cases, they aren’t necessary – 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 via a medium, whether it be air, water, or something else – is first “heard” when it is caught by the external ear (which is the obvious 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 parts of the ear right until they interact with the ear drum and interior ear (those parts of the organ located inside of your skull), where they stimulate hair cells, sending nervous signals to the brain. These signals are then translated as sound. Yes protection equipment come in a variety of forms.
Because of to the physically miniscule and fragile 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 discharge sound is very similar 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 pieces of the human ear. Sounds experienced at places like construction zones or rock concerts are very easily able to damage the ear over long durations of exposure. By simply blocking such sounds from entering the ear, ear plugs can prevent this.
Aside from protecting your actual capacity to hear, the protection supplied by ear plugs also maintains another critical function of the ears that is much 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, related to the way two working eyeballs allow depth perception). Deep inside the interior ear are the organs responsible for determining one’s orientation to gravity, and a sense of steadiness.
Very small fluid packed sacks send nerve signals to the brain which usually interprets these signals to establish a sense of physical orientation against the background environment. Since the fluid inside these sacks is subject to the very same laws of gravity as the rest of the body, the brain can interpret their orientation the same way you might if you observed a soda bottle half filled. Regardless of what angle you look at it, you can figure out a sense of up and down by seeing in which direction gravity pulls the leftover fluid inside the bottle.
