Everyone has that moment when they have to ask, “is that what I really sound like?”
Whether it’s watching back old home videos or listening to yourself record your own message bank – everyone hates it.
And now, Science has provided us with an answer.
Basically, it’s all to do with our anatomy within our ear.
The three main parts of the ear are the outer, middle and inner ear; and each have different functions.
The outer ear is the piece of cartilage that hangs off each side of our head, and it opens up to the ear canal.
The eardrum separates the canal from the middle ear, which contains three bones and are t he main conductors of sound – they amplify and transfer the sound to the inner ear.
The inner ear comes right before the brain, and it contains the cochlea, which changes sound into the neurological signals to take to the brain.
According to the American Academy of Otolaryngology:
“The vibrations are passed to the three small bones of the middle ear, which transmit them to the cochlea. The cochlea contains tubes filled with fluid. Inside one of the tubes, tiny hair cells pick up the vibrations and convert them into nerve impulses. These impulses are delivered to the brain via the hearing nerve. The brain interprets the impulses as sound.”
So, there are two different ways that sound enters our ear – air-conducted and bone-conducted.
Air-conducted noises are everything that enters our ear from the outside, for example: anyone else’s voice.
Bone-conducted sounds are “vibrations from our vocal chords [that] directly reach the cochlea”.
So when we listen to our voice, we actually hear a mixture of bone and air conducted noise – it’s basically our own voice bouncing around in our head, that is unique for everyone.
But when we hear our voice in a voice-recording, we are only hearing the air-conducted sound that our voices make.
Why does this annoy us so much??
According to SciShow science expert, Hank Green, it’s because of how we learnt to speak as babies.
We’ve spent our whole lives trying to replicate sounds and hear ourselves one way, that when we hear ourselves recorded it can freak us out.
We also think our voices are a lot deeper than they actually are because of the bone-conducted sounds we hear.
