Hazards of Earphones
How often do you use your earphones? Even though people are well
aware of the side effects of earphone usage, earphones are still many
people’s go-to due to their noise cancelling capabilities. Since earphones can
provide exclusive music hearing to yourself and block external noise, people
tend to ignore its adverse effects. However, we should shed new light on the
downsides of earphones that threatens one of our most important parts of our
body, the ears. If you put your earphones on and listen to them for a long
period of time with high volume, you will have high chance of hearing loss and
might as well become deaf.
When a high frequency sound reaches our ears, that
sound knocks the basal part of cochlea. There are cilia on it. Cilia are
sensory organelles that receive vibration and changes the sound into electronic
signals. After that, the signals get
transferred through neuron system and are sent to the brain. However, during
this process the basal part and subsequently the apex part of cochlea get
destroyed. Even though cochlea do have self-healing abilities, when those parts
are irrevocably damaged or destroyed due to its constant exposure to high
frequency sounds, the cilia will inevitably come to its limits. Then cilia will
have a lasting damage and aren’t able to function properly which eventually
leads to a hearing loss. According
to the Journal of American Medical Association, hearing loss in teens is “30%
higher than it was in the ’80s and ’90s”. About 1 in 5 teens have suffered some
degree of hearing loss due to their exposure to loud music by the usage of
earphones. Earphones should be less used, or we shall find an alternative way
to listen to music. Luckily, due to the rapid technological development, we
might soon find a measure to this problem.
