Subject: Hearing loss.
Dear Harish, Please find the information below on the above subject. I feel
since most blind use headphones, this item could be useful. If you feel so,
please send the information to the AI list. About 8 years ago, I saw a TV news
program alerting that a college
student came to an ear specialist. The attending doctor shook his
head because he couldn't find the reason or cause of the young
patient who was losing his hearing capability rapidly.
The young man visited several hospitals seeking for help, because he
nearly lost his hearing capability.
Responding to the TV news, one of private research institute offered
to study the young man in exchange with publication in a certain
company advertisement.
The research group conducted the case and concluded that the college
student was a music lover who was using high fidelity loudspeaker
amplifiers. Since the time he enjoyed listening jazz and pop music
with the latest model of amplifier, he became the victim of modern
life.
Some amplifiers produce strange sounds or frequencies that destroy
several parts of the body. Once again, the news went around and many
inquires came to several research groups.
Yes, we knew now that many headphone users among music lovers are
reportedly having some hearing difficulties.
We believe that some frequencies and loud sounds coming from the
earphones make the eardrum to be thickened reducing hearing
capabilities. Most patients who have difficulties in hearing are due
to them using portable music players like the above photo, especially
at high frequency and middle frequency of about 400 Hz and lower
frequency of about 100 Hz below. We understood that eardrums do not
respond nor vibrate due to the thickening of eardrums, and this is
one of the new strains of illness in modern age.
There is nothing wrong with portable music players. It is only
because users set their music players to a high volume that can
destroy their eardrum. That is how doctors comment.
However, in some cases of music lover who lost almost all his hearing
capability was not only because of loud sound. Some loud sound Hi-Fi
amplifiers produce strange sounds or frequencies that destroy not
only eardrums but also internal organs. Do you believe that?
