Hungry for some more
facts? Allow us to take
you to a world of 20
interesting human ear
facts. From their
functions to the
mysteries of long ears
– here we are today
going to learn some
fascinating facts about
this very important
body organ. Perhaps,
some of you will already
be familiar with these
facts but a refresher
course is always good –
not just for knowledge
but also for fun!
Interesting Human
Ear Facts: 1-10
1. Let us start with
something that
everyone knows. Ears
are organs designated
for hearing. But, did you
know that there is a
limit till which ears will
behave properly. The
moment a sound
exceeds the natural
hearing limit, our ears
will buzz! How about
asking your friend to
shout at his or her
highest possible volume
right into your ears?
The result will be
buzzzzzzzzzzzzz……
2. Did you know that
our ear has 3 bones
which are so small that
they can be placed
together on a penny?
These three bones are
called stapes, malleus
and incus. Fancy names,
huh? Well, the first
fellow, i.e. stapes is the
smallest of these three
bones.
3. Wanna go merry-go-
round for a few days?
Simply damage your
inner ear and voila,
mission accomplished!
On a serious note
though, ‘merry-go-
round’ in this context
means losing your
body’s equilibrium. Inner
ear has direct
connection with brain
and anything happens
to the inner ear means…
you get it right?
4. Ever wondered why
every time you catch
cold, you go dumb? I
mean, you lose your
voice! That’s because
middle ear is connected
to the throat using a
tube named Eustachian
tube. This tube is
responsible for striking
equilibrium between the
body pressure and the
atmospheric pressure.
5. We just mentioned
inner ear and middle ear.
This simply means that
human ear is divided
into three parts – the
outer ear, the middle
ear and the inner ear.
Each part has separate
functions. The outer ear
is the visible part of the
ear and its function is
to direct the sound
further inside. The
outer ear ends where
the eardrum starts.

6. The area after the
eardrum is the middle
ear which ends at what
is known as oval
window. This middle ear
consists of the three
tiny bones we
mentioned earlier. The
sound that enters the
outer ear makes the
eardrum vibrate. These
vibrations are picked up
by these three bones
which actually form a
bridge. The last bone is
the stapes (in order of
arrangement inside the
ear). The stapes
transmits the
vibrations to the oval
window. The middle ear
is the place where the
sound gets amplified.
7. Finally comes the
inner ear. The sound
transmitted to the oval
window moves into the
inner ear which is
actually a network of
passages and tubes.
This network is often
referred to as
‘labyrinth’. This inner
ear has a small snail
shell-like organ known
as cochlea where the
sound is transformed
into electrical impulses.
These impulses are
then sent to brain’s
auditory center using
auditory nerves and
voila! We can hear!
8. In inner ear, the
sound waves moves
into a liquid medium.
The tiny hair cells
present in inner ear
react to the sound
waves traveling
through the liquid
medium. This causes
the hair cells to release
chemicals that are
carried by auditory
nerves t
