HOW DO WE HEAR
When we open
our eyes we saw something around us which is physically exist. But it does not
happen with the hearing. Hearing is a special kind of sense that we can feel
only but we can not touch. As we know that hearing loss is a very big problem.
As we discuss earlier that there are so many devices exist that can be used to
solve the problem of hearing loss and provide the original sound. Hearing is a
natural phenomenon. It is just like the magic.
But the question is how we hear and
what is the process so behind the hearing?
Hearing
looks unusual. But it’s a very important part of our body. The outer cupped of
the ear catches the sound wave and transfer them into a series of complex
sensors. These sound waves travel through the ear canal that makes the eardrum
and tiny bones vibrate. Nerves in your inner ear pick up these vibrations and
convert them into the electrical impulses to your brain. Your brain than
identify these electrical pulses in the form of sound, music and noise etc.
If the sensory
part of your brain damaged, then the hearing sense is affected. This may be
because some part of ear blocked. Nerves get damage. Sound wave does not
processed correctly because of nerves damage and blockage of ear. So the
hearing aid helps the people to hear the sound clearly.
