Deafness of the great composer Beethoven causes bewilderment among schoolchildren: how could he write music?! This is one of the most striking examples of how bone conduction of sound can help a person: the composer applied special tubes to his head to hear the sound, and we, thanks to this technology, can enjoy the masterpieces of a romantic genius.
How bone conduction works
Our auditory system is divided into outer ear, middle ear and inner ear. The bone conduction of the sound bypasses the two channels, sending sounds directly to the inner ear.
Bone conduction devices do not cover the ears, so a person can listen to music or talk on the phone and respond to surrounding sounds.
What will be the sound of bone conduction headphones
Unlike the sound you are used to with headphones. The most obvious difference - with bone conduction bass felt and not heard. Basis headphones — piezodynamic, which converts sound into vibrations, and they, in turn, at high volume the bass is transmitted as a vibration, and you feel the music body. Bone conduction technology should appeal to music lovers who literally die because of the thick bass.
- At the same time there are no distortions, drops, stutters or wheezes in good headphones — it's the same music, but with vibration in place of deep bass.
Another undoubted plus: listening to music in bone conduction headphones is considered safer for hearing, as our bones are stronger than eardrums. And contrary to popular belief, the vibration from the headphones will not hurt you in any way. Cover your ears with your fingers and say a few words. Hear yourself? We perceive the sound of our own voice with the help of the same bone conduction. And that, by the way, explains why he seems different on the record.
Because skull bones conduct lower frequencies better than air, people's own voices appear lower and deeper than what they hear around them; in the recording, the voice often sounds higher than expected.
Use in the 21st century
- Google Glass
- In April 2016, Rostek Corporation announced the beginning of the release of a set for soldiers
- Also, these headphones are often used by athletes and office workers
The leader in the market of headphones for bone conduction is Aftershokz.
