Introducing The Sound- Bite Machine: Hearing With Your Teeth! Find Out!

Tooth headphones

Hearing with your teeth? Sounds like science fiction? No it's not! With this 'tooth headphone' you can experience it for yourself. Sound usually enters your ears and travels to the inner ear via a serious detour. But you can skip a couple of steps and hear directly with your 'bones'. Scientists call it 'bone conduction'.

Single sided deafness affects around 200 out of every million people the world over.

The loss of stereo hearing can prove dangerous when crossing the street, or other mobile environments.

Sonitus Medical has developed a new device, SoundBite, that uses the natural conduction of teeth and bone to transmit sound to the inner ear even after the outer and middle ear are damaged.

SoundBite Hearing System is a non-surgical bone conduction prosthetic device that transmits sound via the teeth. It is an alternative to surgical bone conduction prosthetic devices, which require surgical implantation into the skull to conduct sound. SoundBite uses the tooth instead of the implanted component and eliminates the need for surgery. It is therefore typically lower in complications and in cost than the prevalent surgical treatments.

Parts of sound- bite system

Sound Bite is a music player connected to two metal rods rather than a speaker system. Music is played within the exhibit which is too quiet to hear, but by biting on a metal rod (through a disposable straw) the sound is transmitted through your jaw bone straight into your ears.

SoundBite Hearing System has two principal components: a behind-the-ear (BTE) microphone unit that is worn on the impaired ear and a removable, custom-made in-the-mouth (ITM) device worn on the upper, left or right back teeth. Both components have rechargeable batteries and a charger is included with the system.

What?s the science behind it?

Sound needs to travel through a medium, such as air, water or a solid. Normally we hear sounds when they travel through the air. The sound waves travel into our ears and cause the bones in our inner ear to vibrate. These vibrations send signals to our brain that we hear as sounds. When you use Sound Bite if you bite down on the metal rod you hear music playing through your teeth. This works because a speaker is attached to the rods and is playing music. When you bite the rod the sound waves travel through the rod and through your teeth and skull to the bones of your ears.

Mechanism behind the machine

Science in your world Hearing aids use bone conduction to help people who can?t hear very well. The part of the hearing aid on the outside of your head detects sounds around you and then transmits it to another part attached to your skull. It means you can hear sounds without them having to go through the parts of your ears that aren?t working.

SoundBite detects noise using a microphone placed in the ear connected to a transmitter in a behind-the-ear (BTE) device. The BTE transmits to an in-the-mouth (ITM) device that sends small sound waves through the jaw to the cochlea. There is no surgery needed, and both the BTE and ITM are easily removed to be charged inductively.

Hear through this device using your teeth, will be more helpful to the deaf people, this sensing device puts light on its unusual usage, materialising into something more useful
