What Does A Cochlear Implant Sound Like?

Cochlear implants don’t generate sound like a hearing aid would. Instead, they zap your cochlea.

Maryyeung12894 says:

her pronunciation of “cochlea” is so cringe. its pronounced like coke.

EllaSandboxdrawer says:

I’m deaf and I had to use subtitles for this and that’s becuase it was three days ago I had my operationm (I’m a child)

Chase Watkins says:

It’s hard to describe to people so the way I describe my cochlear implants is like watching a TV with only 22 colors. I get the “image” but it can be difficult to distinguish between some moss growing on a leaf if they’re both the same color. As a result, I never heard the rolling “r” in Spanish even though I lived in Argentina for months unless it was over-emphasized.

I used to have an analog hearing aid in my right ear (severe to profound) hearing loss and going from an analog hearing aid with no filtering to a digital cochlear implant with 22 electrodes and filtering sounds so different that I miss listening to music with my hearing aid. That being said, I never understood the lyrics of music with my hearing aid so I gained some and lost some.

SotraEngine4 says:

It’s super fantastic how we can give senses to people. We can give terrible hearing to deaf and terrible sight to blind. Terrible quality, but still fantastic

Lana Hardie says:

It’s pronounced like cokelea not cocklea

DuluthDawn says:

https://youtu.be/psx8UpM5wLc for cochlear implant detected speech and music

BloodnutXcom says:

Came for an demo of something similar of the real thing. went away disappointed.


Thanks for helping me learn about cocklear implants

Doom says:

Disliked because of dat ugly b!tch

IAmAgainst says:

It shouldn’t be difficult to filter a normal sound signal to allow only the spectrum the implants can reproduce. Knowing how they work, there’s always a tool to reproduce the effect to a certain level of accuracy. I was expecting they did something like this in the video.

Brent Alexander says:

Hahahaha I was laughing the whole time she said cochlear Implant wrong the whole time

pyrotheevilplatypus says:

I always thought the “o” was long in cochlear…

Yougotnomilk says:

i nearly lost my hearing when i was 3 to get two of these implanteded as im deaf luckily my mum said no and i can still hear things but just not as loud or clear as others maybe able to

Kevin Ku says:

hmmm so we have to find a way to increase the number of frequencies being inputted

None of your Business says:

Why no demonstration? A pretty good approximation of what you describe can easily be achieved with a *vocoder* : 24 bands, each with it own sine wave as a base signal, will do the trick, effectively reducing the audible spectrum to 24 single frequency bands.

Mars Violet says:

That must be why my deaf cousin speaks so weird…

K Parmelee says:

If you want to come across to your audience as credible, make sure you pronounce the operative word of the topic you are discussing correctly. The word “cochlear” is pronounced COKE-LEE-ER; not COCK-LEE-ER. Geez!

LS Zoo says:

Any one else annoyed how she pronounced cochlear

Amanda Striffolino says:

Read this as “what does a cochlear eggplant sound like?” Thoroughly disappointed by the lack of eggplants but still 10/10 good video.

FacelessDeviant says:

1. I am way too childish to hear the phrase “zap your cochlea” without giggling like an idiot.
2. Having never heard a talking doll low on batteries, I would have appreciated if the clip featured an example.

Beren Godric says:

That’s the cochlear nerve btw, not the auditory nerve, which combines with the vestibular nerve to become the vestibulocochlear nerve, which is one of the cranial nerves.

Vaibhav Bali says:

Why the implant is there in your nose??

Umar_Gaming 9000 says:

I got the new N7 and the speech that u did was helpful and u are giving in the right info

Adam Walsch says:

_If anyone is interested, _*_I can record some sounds and filter them to sound like a Cochlear Implant._*
I have a special Vocoder (a type of synthesizer) which lets me limit the number (and width) of returned frequencies.
It certainly sounds strange, and as Olivia says, some people may need to train themselves to understand what they’re hearing. But for those with an attuned ear (or rather, brain) it’s not too hard to make out words and different sounds.

Journal of Paradox says:

It’s really difficult to describe.

Benny S. says:

As a person who has moderate hearing lost in one ear and a cochlear in the other, my cochlear only picks up beeps clearly. For example, I can hear a fire alarm with my cochlear implant, but cannot without. When my phone is playing music, my cochlear can pick up the noise but not the “music” itself. It’s like a… Muffled version of everything. Plus, with the cochlear implant, everything sounds much more clearer in my left ear. My cochlear can pick up the S, Sh, Ch, T, ect, sounds that my left ear cannot. Hope this helps.

Kendon Chase says:

No sound clip? How disappointing

B Brown says:

The people Sci-Schow are employing are becoming harder and harder to take seriously.

Shekhar Banerjee says:

QQ:do counting sheep actually help us sleep?

Christian Collins says:

Omg the pronunciation

IntarwebUser says:

“If you’ve ever heard one of those talking dolls when it’s running low on batteries” – No, I have not. Why don’t you play a five-second sample clip for me?

*John Smith* says:

Why does she dance when she talk

ChewyWolf says:


Tamisan Latherow says:

https://www.youtube.com/watch?v=1dhTWVMcpC4 check out 3:33. The girl tells you what her cochlear sounds like.

Angela Botz says:

This video should have been captioned. Please be considerate for equal access.

hoseja says:

Are there direct computer-to-cochlear interfaces? Without a speaker/headphone inbetween I mean. Like you wanna watch a youtube video so you plug yourself directly to the 3.5mm port or something.

Connor Goeke says:

Damage to the hairs in the cochlea are one of the causes of tinnitus. The broken hairs move even when there aren’t vibration and the electrical signals this movement creates are what causes the brain to hear the tinnitus.

Wes8761 says:

No offense but the narrator looks weird

Insignificant_Anon says:

The way she says “cochlear” makes me wish I was deaf.

Big Can O' Bleach says:

Lol, im watching this with my cochlear implant

desertrose0601 says:

Preeeety sure that’s not how you pronounce that word. It’s a long o, as in “so” or “coke”.

Justin Avila says:

Knowing what cochlear implants are and how they work, I wanted to know what they sound like. I eagerly waited 3:30 and was very disappointed and completely let down after never finding the answer to my question. Poorly named video guys. Can I have my 3:30 back please.
