Bone conduction headphones: transmit sound waves via the user’s skull instead of his ear canal

Bone conduction headphones

In today’s world, headphones are not enough to just listen to music or even a song. But, now used in many other works besides composing calls and songs. We use different types of headphones. Such as over-air headphones, on-air headphones and in-air headphones. And there are also headphones with Active Noise Cancelling, with IPX4 rating, different Bluetooth versions and with Bluetooth multipoint. In the midpoint of all these headphones you have ever heard of such headphones which are fill not by the ears but by the bones above the ears. You will be surprised at the first, But this is possible. There are also headphones that allow you to listen to music or songs without using your ears. Such headphones are called Bone conduction headphones.

What is Bone conduction headphones?

Bone-carrying headphones are also known as ‘Bonephones’. These headphones are those that transmit sound waves via the user’s skull instead of his ear canal. When in use, the user’s skull bones will vibrate to intensify sound waves. That allowing users to listen to the device audio while keeping their ears free. The biggest beneficiaries will be people with hearing loss. Or people who need to use their ears to be aware of their surroundings.

How Bone conduction headphones work?

Bone conduction headphones

Bonephones use a method called Bone Carrying Audio Technology to listen music or songs without ears. In this method, the transducer converts the audio data into vibrations. Which travel to the cochlea along with the user’s bone structure, an inner ear structure. That transmits information along the auditory nerve to the brain as a signal. In effect, the user’s skull is the device’s speaker. This is in stark contrast to ordinary headphones. Which emit vibrations through speakers placed inside or above the outer ear.

Sound is scientifically just the vibration of a particle. Generally, people usually think of trembling in the air when they think of sound. But sound can also travel via solids and liquids. As consequences, flesh and bone can behave like speakers, as solid particles can also vibrate. Honestly, solids transmit sound faster than air and water. Because solid particles are packed together most securly. This makes solids the best conductors of sound, then water, then air, which has the arrangement of loose particles.

This seems paradoxical, as listeners generally experience distortion in sound when trying to hear something through a liquid or solid. If a listener is underwater, a person speaking above the surface will make a croaking noise. If loud music is played nearby, the listener will usually find it confusing. This distortion is not because liquid and solid are bad sound conductors. But because in both instances, the sound passes first through the air, then into another medium.

Bonephones are designed with this fact in mind. Most models have straps wrapped around the back of the user’s head, protecting the vibrating pads against the skin above each ear. The pads rotate slightly over the top of the ear to help keep the device in place on the user’s head. Protecting these pads against the user’s skin reduces sound distortions as the sound travels directly from the pads into the skull in a direct shot, without air in between.

Bone conduction headphones uses

Bone conduction headphones

In generally, just like the regular headphones, bonephones are use to allow persons to hearing to audio. However, bonephones are different because they bypass the outer and middle ear absolutely. They also have a unique design that lends itself to physical activity, unlike most basic headphones. For these reasons, they may be prefer over regular headphones.

  • Gym goers and other physically active people who need headphones designed to stay on their head while exercising;
  • Joggers or bikers who want to keep their ears open to get close to traffic. Or people are trying to tell them something.
  • Users who listen to audio in a social environment and need to be at least partially balance for what colleagues or announcements are saying.
  • Users with impaired hearing, whose use of standard headphones may be physically block by assistive technology.
  • And also users with impaired hearing who may experience better sound quality through bone conduction than damaged ear.

Advantages

The most common advantage of Bonephone is that it does not use the ear to listen to audio. As a consequence of, this is beneficial because they can use their headphones while remaining attuned to the outside world.

Bonphones also terminate the risk of hearing loss that comes with hearing too loud through standard headphones. The eardrum is more delicate than the flesh and bones on which the bonephones works.

Earphone bypass is extremely beneficial for hearing-impaired users as it enables them to listen to audio with greater clarity than previously enabled by standard earbuds. In case, a listener who is deaf in one ear will be able to hear audio in a stereo through a Bonephones. In addition, if the listener has a hearing aid, they can also leave it on while listening to music through bone carrier headphones.

Their slim and secure design also makes them attractive to physically active users. A Bonephones manufacturer – Aftershocks – originally designed Bonephones for use in the military. Some bone-carrying headphones also have memory, and users can upload songs directly to them. This could be another selling point, especially for active users.

Disadvantages

In spit of, all these advantage and uses, some users gave a mixed response after its use. A lot of peoples are complaining about the audio quality in bonephones is worse than regular headphones. In particular, users report that they are generally quieter and have weaker bass frequencies.

Physical design also has downsides. Some users notice that playing music at high volume causes an unpleasant or strange vibration sensation on their face. This design also causes a certain amount of sound leakage, which can be a problem for those who want to hear something privately or in a quiet setting without disturbing anyone. Other users complain about the fit of headphones, which, depending on the user and model, can be uncomfortable.

Bone-carrying headphones are also significantly more expensive than run-of-the-mill earbuds. In 2020, basic Apple earbuds will cost around $ 30, while some popular bone-carrying models will cost around $ 130. For this price, users can purchase generic headphones with better sound quality than some bone carrier models. Some very cheap bonephones are available, but more expensive than most options.

Top Bone conduction headphones

Bone conduction headphones

Bonephones are commonly market to athletes because of their sleek design. Some of the top bone conduction headphones on the market include:

Despite the fact,

The idea of ​​using bones as an amplifier seems modernistic, the idea has been around for ages. Beethoven, the songwriter of classical music, uses bone carriers to help him continue writing music after he became deaf. He held one end of the rod in his mouth and the other end in front of the piano. Which sending vibrations through the rod to his skull, allowing him to “hear” the music he was playing. However, some animals are also able to communicate through bone vibrations.
