Can Others Hear The Sound From Headphones with Bone Conduction?
I believe you also have the common experience that when we eat cookies, even if we cover our ears, we can hear the cracking sound of cookies. Or when we scratch our head, we hear the sound of fingers rubbing against our head. This is actually the most common example of bone conduction.The vibration of a cookie or the friction of the head is transmitted through the skull to our inner ear, which helps us to hear sound. This sound transmission method has also been cleverly applied by scientists to headphones with bone conduction, and in the past 2 years, they have become the most popular digital product.
So, what are headphones with bone conduction?headphones with bone conduction are headphones that are worn differently from traditional headphones. Because of its high technical maturity, its performance is very stable, and its reliability has been widely recognized. This is also the reason why headphones with bone conduction can become popular so quickly and are recommended by many professionals.
How do headphones with bone conduction work
Before explaining how headphones with bone conduction work, let me briefly explain how humans hear sound.
The most common way we hear sound in our daily life is that sound reaches our ears in the form of vibrations in the air. This vibration travels through the ear canal, vibrates the eardrum, and reaches the cochlea to help us to perceive sound. The cochlea is shaped like a snail and is responsible for transmitting sound information to the brain. But humans can also hear the sound without using the ear canal. For example, when we chew nuts, we can hear the sound without passing through the air, that is, the sound is transmitted through bone conduction.
Bone conduction technology is a mechanism that transmits sound without passing through the ear canal or eardrum, instead the bone around the ear vibrates to transmit the sound signal to the cochlea. It should be noted that we hear sound with the cochlea instead of the eardrum, which is just an intermediate step in the process of air-conducting sound. When people hear sound, whether it is air conduction or bone conduction, if the appropriate vibration reaches the cochlea, they can hear the sound.
Headphones with bone conduction are sound-receiving devices made of bone conduction technology. During the sound transmission process, they directly bypass the ear canal and eardrum and reach the cochlea. Compared with air-conduction headphones, there are fewer steps for sound transmission when using them. Just because they take a shortcut, they also reduce the damage to the ear canal and eardrum, making them the healthiest headphones.
Can others hear the sound from headphones with bone conduction?
Under normal volume, with a social distance of more than 1 meter, it is difficult for others to hear the sound of headphones with bone conduction. Therefore, the privacy protection of the headphones is still good, and you can use them with confidence.
The reason why some people worry that "others will hear the sound of headphones with bone conduction" is mainly because the headphones generally have the problem of sound leakage.
However, due to the advancement of technology, mainstream bone conduction headphone brands have solved the problem of sound leakage well. Under normal social distance, your privacy is still guaranteed.
From the point of view of the principle of sound, all headphones with bone conduction have the problem of sound leakage. Because they rely on the vibration of the sound unit to generate vibration waves, and drive the bone to vibrate to transmit the sound to the inner ear, so that it can be heard by people. Therefore, when the headphones are working, their shells will vibrate together with the sounding unit, and the shells will drive the air to vibrate, resulting in sound leakage. For the same headphone, when the volume is higher, the sound unit vibrates more, the air vibrates more, and the problem of sound leakage will be more serious.
Excellent bone conduction headphone brands have made a lot of efforts to solve the problem of sound leakage of headphones, and mainly adopted the following methods to reduce the problem of sound leakage.
Integrated body: The headphones body is designed as an integrated body without holes, so that there is no air in the body, and the air vibration caused by the sound unit is also reduced;
Shock-absorbing design of the body: through structural optimization, the shock-absorbing function of the body is improved, and the vibration of the body caused by the vibration of the sound unit is reduced;
Inverted-phase sound wave: The anti-phase sound wave is used to cancel the sound wave of the sound leakage, thereby eliminating the sound leakage.
It should be said that their efforts have paid off. The sound leakage problem of some excellent brands of headphones with bone conduction has been well resolved.
Although headphones with bone conduction have the problem of sound leakage, it has to be said that they have several outstanding advantages: they allow you to keep your attention on the ambient sound while listening to music, which is very safe; they will not hurt your ears, can Keeping the ear canal hygienic and more. These advantages are why they have become popular.
If you are interested in bone conduction headphones,here are some excellent headphones for you all.
1. Wissonly Hi Runner headphones with bone conduction
Reason for recommendation:
Wissonly headphones with bone conduction are the first brand I started to contact. When they recommended it on the online crowdfunding platform, I noticed it, after saw that many people were recommending, and I bought it. This Hi runner I used for a few months, and the overall performance was better than I expected.
Some headphones with bone conduction leak sound, and you know that I take privacy very seriously, so I'm very concerned about anti-sound-leakage technology. Wissonly Hi Runner does a very good job in the field. Its body is sealed, and through structural optimization and algorithm adjustment, its sound leakage is minimized. The official claim they can eliminate 90% of sound leakage. I do not have professional equipment to test, but I have tried and found that at 60%-70% volume, the sound is completely inaudible at a distance of 1.5 meters, which makes me very satisfied. I have actually compared it with other headphones with bone conduction, and the Wissonly Hi Runner has currently the best sound leakage reduction solution in headphones with bone conduction.
The Wissonly Hi Runner is also particularly comfortable in the wearing experience. Because the material of the whole machine is high-tech hypoallergenic silicone, and it is coupled with the ergonomic design that conforms to the structure of the human ear, so that users will not bring any burden to the ear under long-term wear.
Sound quality as the core performance is undoubtedly worth mentioning. Hi Runner uses a large-sized vibration unit, the sound range is wider, the sound is more three-dimensional and deeper, so the sound quality is undoubtedly very good. And it is also equipped with a Bluetooth 5.0 chip, the connection is more stable. And it will not be disconnected when used, which is a good experience. The Wissonly Hi Runner also comes with 32GB of built-in storage that can store 5,000 songs, so you can use it completely as an MP3 player to enjoy music without your phone when you go out for a run.

Reason for recommendation:
The A6606 has a skin-friendly material on its surface, which greatly increases its wearing comfort. It adopts a 15mm size sound unit, which produces better sound and is more suitable for noisy environments. Its bass effect has also been improved. The waterproof level of A6606 reaches IP67 level, not to mention rain, even direct rinse is no problem at all. But after all, it is not professional-grade waterproof, it cannot be used in swimming or diving.
