- Hi guys, in this video,
[1]
I'm gonna teach you about
[1]
the three different types of hearing loss,
[3]
and what causes them.
[4]
Comin' up.

I'm Cliff Olson, Doctor of Audiology,
[13]
and founder of applied hearing solutions.
[15]
And on this channel, I cover
everything you need to know
[17]
about hearing loss, and
your treatment options.

[23]
As an audiologist, I
spend all day, every day,
[26]
testing and treating individuals
who have hearing loss.
[29]
Nearly 50,000,000 people
in the United States alone,
[32]
have hearing loss.
[34]
Of these 50,000,000 cases,
[37]
there's only three
general classifications,
[39]
but many conditions that
can cause each type.
[43]
Some of these are common, some
of these are not so common.
[46]
Nonetheless, I wanna share with you,
[47]
the three classifications of hearing loss,
[50]
and some potential causes of each type.
[53]
The first type, is sensorineural.
[55]
Despite what the name
says, most of the time,
[57]
it isn't the auditory nerve
itself that has the problem,
[60]
but it's the little tiny hair cells
[62]
that are inside your hearing organ,
[64]
otherwise known as your cochlea.
[67]
These hair cells, flex and move
[69]
when sound comes into the ear.
[71]
Their movement sends a signal
through the auditory nerve,
[74]
to the brain, causing you to hear.
[76]
If these hair cells don't work right,
[78]
you'll have a hearing loss.
[80]
Some of the most important causes
[82]
of sensorineural hearing loss,
is noise exposure, and age.
[87]
If these hair cells
sustain a lot of damage
[89]
from excessive noise exposure,
[91]
either from impact sounds
like a firecracker,
[94]
or long-duration sounds
like a motorcycle engine,
[97]
you could sustain a
sensorineural hearing loss.
[100]
The good news is, is that
this type of hearing loss,
[103]
is preventable.
[105]
Just wear hearing protection.
[107]
On the other hand, if age is the culprit,
[109]
there's little you can do
[111]
to prevent this type of hearing loss.
[113]
Nearly everyone will develop
this type of hearing loss
[115]
if they live long enough.
[117]
Sensorineural hearing loss
is treatable by hearing aids,
[121]
when the outer hair cells are
the ones that are damaged.
[124]
If too many inner hair cells are damaged,
[126]
it prevents the proper
transmission of sound to the brain,
[129]
and will limit the hearing aid benefit.
[132]
Other less common causes of
sensorineural hearing loss,
[135]
are sudden hearing losses, and
acoustic neuromas, or tumors.
[140]
Both of which generally occur
in only one ear at a time.
[143]
If you ever experience
hearing loss in only one ear,
[146]
get to your doctor immediately.
[148]
Sudden hearing losses are
generally caused by a virus
[152]
attacking the hair cells of your cochlea
[154]
that we just talked about.
[156]
Treatment includes steroids,
[158]
but success with treatment depends
[160]
on how quickly you receive it.
[162]
And acoustic neuroma, or tumor
[164]
can also give you a sudden
hearing loss, but not always.
[168]
This is when a tumor is
growing on your auditory nerve,
[171]
and blocks sound from
making it to your brain.
[174]
Obviously, anytime a tumor's involved
[176]
it becomes more serious.
[178]
The second type is a
Conductive hearing loss,
[181]
or mechanical hearing loss.
[183]
A conductive hearing loss,
[184]
is one that's caused
by something preventing
[186]
the proper transmission
of sound to the cochlea.
[189]
In this case, there is nothing
wrong with your cochlea,
[192]
or auditory nerve, just
the sound can't make it
[195]
from your outer ear all
the way to your inner ear.
[198]
Sound has to travel through the ear canal,
[200]
vibrate the ear drum,
which causes the ossicles,
[204]
otherwise known as the
hearing bones, to move,
[207]
and then they move the
fluid inside the cochlea
[209]
to cause that neural impulse.
[211]
If any link in that chain
has a problem doing its job,
[214]
you'll have a conductive hearing loss.
[217]
There are many causes of
conductive hearing loss.
[220]
Some of the most common are earwax,
[223]
which block the vibration of sound,
[225]
an eardrum with a hole in it,
fluid behind the ear drum,
[229]
disconnected ossicles,
or even fused ossicles.
[232]
A simple hearing test is able to identify
[235]
exactly where the problem is.
[237]
Conductive hearing losses
[238]
often require medical intervention,
[240]
and sometimes require surgery to correct.
[243]
The third type is a mixed hearing loss.
[245]
This is when there's a component
[247]
of a sensorineural hearing loss,
[249]
combined with a conductive hearing loss.
[251]
This type of hearing loss is not common,
[253]
and require multiple types of treatment.
[255]
That's it for this video.
