Hi everyone welcome back to my youtube channel so today I wanted to talk about
Cochlear implants so if you guys know me, or if you're new to my channel
Then you should know that I have a cochlear implant on my right ear
I was born profoundly deaf
And I got this cochlear implant when I was two and a half years old the reason why I wanted to talk about this
It's because
Not many people out there who are famous or well-known have cochlear implants. There's my friend jazzy
She also has a YouTube channel. I will put her link at the bottom of this and
I hope you guys go and follow her cuz she's really really awesome and
You guys would like her she's more of a beauty blogger so if you're into beauty and stuff you should go follow her
anyways
besides
Jazzy, and I think there's few other
People with cochlear implants on YouTube, there's not that many people out there. Yes, there's deaf people
There's lots of deaf people and there's people who do ASL
And there's people who do BSL and there's people who don't do the ASL or BSL and
We just for cochlear implants to communicate and so I want to be that kind of person that people can look up to
so I
Decided that I want to educate people on cochlear implants because not many people know about it
And I don't expect people to know about cochlear implants. It's not something
That's well-known and talked about so I want to say thank you for watching this and please don't forget to Like and subscribe
Because that will make me so happy and please comment below
What you guys want to see for me because that's really awesome, and I know what to film because you guys want that
And I will put a link to my Instagram my snapchat
and
Let's go into the video. We're gonna start with a definition of a cochlear implant, so
cochlear implant is
Electronic device that is surgically implanted into the inner ear
And it provides
sound simulations to the hearing nerve with just an eighth nerve in your head by the way and
It gives a person with no hearing
sensations of hearing
People with severe to profound hearing loss, which I'm in that range
Who cannot hear with hearing aids are
most likely required to have cochlear implants and we
Are proper candidates for it because we have no hearing whatsoever
Like hearing aids who amplified the sound cochlear implant are like mini computers that sit on our ears and
They provide the electrical impulses to the damaged part of the inner ear which is the
Cochlea most likely for most people and it will provide sound signals to the brain. I'll show you guys
What a cochlear implant looks like?
Now we can go into the history of cochlear implants, so
Man that goes by dr. William F
House who was born in Kansas City and raised in Witter
California was a dentist who turned into ear specialist when he took an interest in his family's business
For research he wanted to somehow
stimulate
hearing for a deaf person
so he thought it would be a
Right idea to do it with you electric sound
He was heavily criticized by
Other surgeons and doctors, and they all thought that he was crazy. He officially invented the cochlear implant in
1961 he had put the electrical metal into the patient's
Cochlea, but the body rejected that it became successful in 1969
When the longer-lasting model was successfully developed and the patient's body didn't reject it
It was introduced to the world completely in
1972 by Graham Clark an Australian doctor invented the bionic ear
It's a multiple channel cochlear implant in
1981 and that's how I really know about the history there's
Wikipedia and whatnot, but that's just a small part of the history of when it was invented and who is invented by
Now I'm going to the degree of hearing loss, so
Everyone with the hearing loss have different degrees of hearing loss a person who is an audiologist
Checks everyone's hearing and oh and check deaf people is hearing to see the amount of
Hearing loss that they have so a audiologist would sit in a sound booth and
they would test the individual's hearing the audiologist would mark how you hear on a chart and
it's called the audiogram it tells you how you hear different sounds and
Speeches at different pitches and loudness levels, so those are the two main things loudness
pitch
Hearing is measured by decibel levels which is dBHL
Right there remember this and the number represents the softest sound
Someone can the lower the number is the better you can hear quieter sounds I'm going to start with
normal hearing yeah, so you have 20 decibels and
Lower, so you can hear super quiet sound then the mild hearing loss is from 25 to 39 decibels
so this person
tends to struggle following speech and noisy situations, then a moderate hearing loss
where Hearing Aids are approved at this rate are
40 to 69 decibels
So this person would struggle falling speech without hearing aids
There's a severe hearing loss, which at this rate. You can be certified for a cochlear implant
Which is it's a possibility?
But you could be from 70 to 89 decibels so this person typically struggles
Hearing and this person would need a really really strong hearing aid in order to hear those things um
Almost those don't work bender qualified for a cochlear implant a person profound hearing loss you
Definitely can get a cochlear implant
It's from 90 decibels and up
So a person would rely on lip-reading or ASL without a cochlear implant
I'm definitely in the 90s, and up so there's the audiogram
so
People with normal hearing are in this section you have no
your normal
So this is mild right here, so you can see the 40 so the 20th up is normal hearing
See the smaller your numbers. Here are the better you can hear. This is called the speech
the beach
Wave you think and so this is for letter I with Stan for and
Pitches are from low to high here and from quiet to loud
So I it's a very low pitch
where as
Ths are very high pitch and a quieter on this chart because they're on you're higher up
First the lowest one. I think it's ng or L and rs
Because they're low and you're louder to pronounce the moderate hearing loss
this being this degree here and
Remember, this is low pitches. These are high pitches and the lower that you get
The more severe your hearing losses so I without
Without my cochlear implant I
Can't hear all of this
This question does come up a lot and I would like to clear
It is why can't all deaf people just get hearing aids
You know solve a problem as I said in the chart
There are different levels of hearing loss and some of them were more severe and others
The reason why for a cochlear implant is because the hair cells inside the cochlea
are
Damaged in the sense that they can't pick up sound the hairs are supposed to pick up the sounds in the vibration
But for me and for a bunch of other deaf people they don't really do that job what the sounds
Would do it would get picked up by the hair in the
Cochlea, and it would get sent through the eighth nerve which is the audio nerve and it would be into the brain so you guys can
Hear, I want to talk about requirements to get a cochlear implant
So not everyone can get a cochlear implant
And as I said you need a severe to profound hearing loss in order to get cochlear implant for example a person who
Has no hearing in one ear and hearing in the other ear. They're not qualified to get a cochlear implant because
That would be too much work for the brain to have
natural hearing and an electric hearing and that be two very
different sound
competing in their brain
And that would be too much work for them to hear and it would be quite annoying if someone's hearing starts decreasing
They should be very
very closely monitored by
Audiologist to see if they can be qualified for a cochlear implant
this how the cochlear implant works, so
the sound processor
captures
the sounds that get captured into the microphone by the cochlear implant and
It does a conversion of the sounds into digital
codes
then the sound processor transferred the digital code into the coil which is this part here the
outside maintenance of the cochlear implant
And then we get transfer into the impact which is actually inside my head so the magnet that's it inside my head
would get this sound
And that maintenance right under my skin, it's not in my skull. It's not on my brain. It's just right
I just go on my implant got inside
So just to let you know
the implant converts the digital codes to
electrical signals and it proceeds through the electrode array which is inside the cochlea and
Then the electrode array stimulates the cochlea hearing nerve fiber, which is the eighth nerve
Which passes the sound signals into the brain to produce a sensation of hearing. Now I'm going to talk about
How does hearing loss happen so there's four parts of it here
The outer ear the middle ear and the inner ear and then the brain
So I'm going to start with the outer ear sometimes children born without a pinna
which is this thing here that will curve inside here or an outer ear this whole thing a
person can lose their ear in an accident that can cause a hearing loss a person can have surgery to
Build an outer ear or they can get bone
construction for a hearing aid that is surgically placed
Into the bone in the ear which is called a mastoid bone. The Middle Ear
There's a problem with the eardrum or the middle ear bones
So usually surgery can fix the eardrum or the middle ear bones
This can improve a hearing loss
This is called a conductive hearing loss now the inner ear which is
The hearing loss damaged I have and a hearing loss in the inner ear in the cochlea is called
sensorineural hearing loss, and it cannot be fixed with surgery whatsoever
And the hair cells in the inner ear are damaged and they cannot be regrown
But scientists are working on an experiment right now to try and grow your hairs inside
Birds which is scary children and adults who?
Have inner ear damaged are most likely the one to wear who wear cochlear implants are hearing aids
To help them hear and then my final part is what can cause a hearing loss so
Many children are born without
hearing and
the reason is
most of the time unknown
Sometimes a hearing loss can be a part of the family genetics
and they can be passed on and
It's called a genetic hearing loss and for example the famous deaf person that you've probably heard of Nyle
Nyle yeah, Nyle. His family is genetic has genetic hearing loss
And those families are the ones who are more into ASL because us how the rest of their family grew up to be
sometimes children and adults can become sick with a very very powerful illness
Toxic drugs that are used to help heal them can also take away their hearing loss that can be one of the side effects
Sometimes a hearing loss is caused by illness like meningitis, or a tumor which is really unfortunate
So that's all for my video today. Please give a big big thumbs up and please
comment like subscribe and
if you know someone who has a hearing loss, or if you know some some parent to children who are born deaf I
Would love to have conversations with them, please comment below, please
Ask me anything. I am willing to answer questions
I'll see you guys next time
