An introduction into Bone Conduction
In the past we have discussed many different topics involving audio and sound. We have reviewed topics ranging from understanding TV dialogue, to deciding whether PCM or Dolby Digital is right for your needs. Today we are going to discuss something new. Today we are going to discuss what bone conduction is and how it can help you hear better.
When I first heard of bone conduction I immediately thought of having a bunch of electrodes taped to my head like in some weird experiment that you would see in science fiction movie. In reality, bone conduction is anything but science fiction.
Bone conduction is the conduction of sound to the inner ear primarily through the bones of the skull, allowing the hearer to perceive audio content without blocking the ear canal.
Bone conduction is not a new discovery. Ludwig Van Beethoven overcame deafness by biting a metal rod attached to his piano to hear his work.
It's the same technique that sea mammals use underwater. It works by transmitting sound vibrations along your cheekbones instead of through the air.
This type of technology allows people who are deaf the ability to hear. Swimmers can even hear music under water with this type of technology. The field has even expanded to offer audio communications through other body parts including the teeth and eyes.
From medicine to entertainment, from reef diving to sleeping in our beds, we may have to get used to a whole new set of voices in our head.
