What is the Bone Conduction?

Posted by on

Hey friends! Chris here.


Are you all enjoying the weather?
Starting this week, I’m planning on training for my
half marathon with my pair of Zungle Viper.

YES! RUNNING!

Today I’m going to talk about the most important technology in Zungle Viper, the “Bone Conduction Speaker.”Let’s get right to it.

(For the record, Bose Frames include miniature speakers while Zungle Viper incorporates Bone Conduction Speakers.)

Bone Conductions literal definition is “transmission through the bones.”
So that means Bone Conduction Speakers are “speakers that transmit music through the bones.”  But that brings us to the question, how can you listen to music through your bones and not through your ears?

 

Our ears are divided into 3 major categories: the external ear, middle ear, and inner ear. (Welcome to ZUNGLE ENT)
The external ear includes our earlobes and the external auditory meatus (aka the outermost hole). It’s easier when you think of the middle ear as the eardrum and the inner area it touches. 
Lastly, the Cochlea is part of the inner ear which is where the sound is converted between our brain and ears. 

Whether it be music or voices, sound is “vibrations of the air.” These air vibrations are inputted into the “eardrum” and eardrum also vibrate during this process. Once the vibrations are transmitted to the Cochlea, they are converted into electrical signals which are then transmitted to the brain.

 

This helps us understand the difference between regular speakers and the Bone Conduction Speaker. While regular speakers use “vibrations in the air” to stimulate the eardrum, Bone Conduction Speaker makes “physical vibrations” to stimulate the Cochlea. More specifically, physical vibrations are when sound is transmitted by directly vibrating our skin and bones. 


Bone Conduction Headphones definitely have pros and cons. Since the eardrum is not involved, a positive factor is being aware of background noise while listening to sound.

That’s why it is safe and easy to use outside while bike riding or running!



For people who’ve never used such products, it may feel a bit awkward at first. Like in movies when the main character is having a conversation with his/her friends and simultaneously there’s background music going on… you know what I mean, right?

I think the best thing about Bone Conduction Speaker is how people with ear lobe and ear drum-related problems are able to use it.

 

The downside of the Bone Conduction Speaker is the lower sound quality. That is because sound is not delivered through the eardrum but rather through our skin and bones, it requires more powerful output and it consumes more electricity.

 

 

However, the strengths of the Bone Conduction technology are so clear that many companies utilize it. For example, there are the standard Bone Conduction Headphones (like Aftershokz), Audio Sunglasses (Zungle Viper), and we can never forget, the Google Glass! (Google Glass are also Audio glasses that use Bone Conduction Speaker.)   

 

Oops, I almost forgot. 

A lot of people asked whether or not it is safe to use the Bone Conduction Speaker. As a matter of fact, they’ve been used for a long period time in the army. They were/are regularly used in battle situations when soldiers communicate with one another while being aware of their surroundings.

I heard that it’s a technology frequently used among communist countries.


Therefore, I would like to conclude by saying that Bone Conduction have been around for a long time and it’s safe technology to use. However, if you have BPPV(
Benign Paroxysmal Positional Vertigo), you might feel a bit dizzy when listening to sound at the highest volume. 

Next time I’ll come back with more useful tips and information!

Until then,

Chris
