Hi Everybody. Now I am share with you all a very important topics.IT is very very important for those people who are use earphone. OK now I am start my topics.....
If you listed the benefits of earphones, you could probably go on and
on. You can use them to listen to music while working out, doing chores
or even while waiting for an impossibly long
bus ride to be over. You can also use them to hear what's going on if
your television or computer's speakers are busted. However, no matter
how awesome or beneficial earphones may seem, they still have their
downside.
Hearing Loss
---------------
One of the main
side effects of listening to loud music is hearing loss. According to
Dr. Brian Fligor, the director of Diagnostic Audiology at Boston
Children's Hospital, people who listen to music at volumes exceeding 90
decibels, can suffer temporary loss of hearing. Sounds in this range can
eventually cause permanent hearing loss, especially to teenagers who
wear their earphones for long periods of time.
Decibel Ranges
-----------------
Decibels are the measurement of loudness. If you listen to music at a
restrained volume, then you don't have to worry. However, if you listen
to music at the highest volume possible might want to consider the
following warnings. If you listen to your music using earphones at 85
decibels, you can get permanent hearing loss if you listen up to eight
hours a day. At 88 decibels, you can get the same result at just four
hours of listening time. Now for the painful truth, you can lose your
hearing in just 15 minutes if you listen at 100-105 decibels.
Ear Infections
------------------
Since earphones are made for two ears, it is quite inevitable that
people share them. According to the Manchester Evening News, regular use
of earphones can enhance the growth of harmful bacteria, and sharing or
borrowing earphones may just cause the transfer someone else's bacteria
to your ears. Research leader, Dr. Chiranjay Mukhopadhyay, advises
everyone to avoid sharing earphones. If it cannot be helped, sanitize
them before using.
Tips and Warnings
---------------------
Do not use earphones that are inserted directly into your ear canals
because, even though they can make the music sound better, they enhance
the chances of hearing loss will also increase. You should also try
taking 5-minute breaks every hour. This will help your ears recover from
being bombarded by concentrated sound waves. Last but not least, if you
can use speakers at a moderate level instead, then do so because they
will disperse the sound waves and not cause as much direct damage to
your ear drum.
