Wonder why our voice sounds differently when it is recorded and then played back? It is because human ears hear through two ways: vibration from the air to ear-drum and bone vibration from our inner ear. Our skull conducts lower frequencies better than air, so we hear our voice to be lower and fuller than a recording we hear of ourselves.
Because of this, Bone Conduction has long been a method for the hearing-impaired to listen. As a hearing-aid, Bone Conduction is nothing new, with first use around 1920s. In the two past decades, bone conduction applications have expanded to specialized usage, for helicopter pilots or scuba divers. The main purpose have always been about communication.
However, recently more and more com-panies are developing bone conduction headphones for general consumers. These products are no longer for communication, instead for they are designed for listening to music.
As you can imagine, the technology required to conduct a wide spectrum of frequencies purely by bone conduction is advanced, and no one has really been able to deliver any-thing even close to replacing the traditional headphone, so far.
Why are companies trying, you ask? This has to do the popularization of mobile music listening and exercising. Gadgets for sports and exercises are a grow-ing market for electronics companies, and bone conduction headphone offers a safer method of music listening while jogging or biking, because user’s ears are completely open to the environment.
A couple of brands with help from indiegogo are trying this market out at the moment, is it worth a shot? Tell us what you think.
