Headphones with bone conduction: what is it and how do they work?

the Last few years wireless headphones solidly in trends. A special place among them is gadgets based on bone conduction.

If is still a couple of years ago headphones with bone conduction were rare, today the choice is very wide. They are chosen by the athletes who train outdoors, some users with hearing impairments and fans of non-standard technologies.

What is headphones with bone conduction?

Naushniki с костной проводимостью держатся на скулах человека. При этом звуковые волны, исходящие из динамиков, воздействуют не на барабанную перепонку: они посылают вибрации через челюстную кость сразу во внутреннее ухо, минуя полость среднего уха.

The technology is surprisingly old: it appeared in hearing AIDS in the 1920s, when Hugo Gernsback osion invented the first hearing aid with bone conduction. Currently, the technology has moved beyond medical use and began to provide benefits to a wide audience. Since this headset doesn't block the ear canal, the user is able to hear environmental sounds, and this factor may be of paramount importance in the urban environment.

How does bone conduction?

The ear – only a small part of a complex system in the human body. To understand how the body perceives sound, you need to have at least a General idea about the anatomy of the ear. Look at the picture below.

Обычно звуковые волны поступают через проход в ушной раковине, достигают барабанной перепонки, заставляют ее сокращаться и передавать вибрацию дальше. Naushniki с костной проводимостью тоже передают звуковые волны при помощи вибрации, но через череп: волны проходят по височной кости прямо в улитку, минуя барабанную перепонку, молоточек, наковальню и стремя. Потом запускаются те же процессы, что и при обычном способе восприятия звука. Вибрация заставляет микроскопические волоски улитки (стереоцилии) двигаться. Эти движения запускают ряд химических реакций, в организме выделяются специальные вещества нейромедиаторы, которые стимулируют слуховой нерв. По слуховому нерву импульс отправляется в мозг, а мозг в свою очередь интерпретирует его как звук. Все эти процессы занимают доли секунды.

The bone has a better low frequency sounds than high frequency, so we often wonder how unusual ringing sounds like our own voice in the recording.

Naushniki с костной проводимостью отличаются от обычных затычек и беспроводных гарнитур в первую очередь тем, что не вставляются непосредственно в ушные раковины. Поскольку звук поступает в органы слуха не традиционным путем, эти наушники могут быть настоящим спасением для тех, кто страдает нарушениями слуха из-за травм барабанной перепонки.
