How Do Bone Conduction Headphones Work and How About The Safety of Them?

 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 bone conduction headphones, and in the past 2 years, they have become the most popular digital product.

Bone conduction headphones are headphones that are worn differently from traditional headphones. And their don’t need to tuck earbuds into ears like that common headphones to help sound transmit to the eardrum through the air in the ear canal. They are generally hung on the pinna, so that the sound unit is placed against the temple. And the mechanical vibration signal of the sound unit is transmitted to the auditory nerve of the inner ear through the skull, and finally the sound is heard.

Bone conduction headphones are very safe and health.

The safety of bone conduction headphones?

Bone conduction headphones are a new application of mature technology, and their safety has early been verified.

First of all, bone conduction headphones have very little damage to hearing. We all know that hearing damage generally occurs in the eardrum and inner ear. When we wearing them,sound do not need to pass through the eardrum, so they do not damage the eardrum. Because the oscillation of them is relatively moderate, the headphones also have less effect on auditory hair cells in the inner ear. Moreover, the electromagnetic waves of them are extremely weak that they will not cause harm to human brain nerves and hearing nerves.

Secondly, bone conduction headphones can still keep you paying attention to ambient sounds when worn, which can help you to avoid many accidents. They are not worn into the ear, Whether in running, cycling, walking or commuting, etc., wearing the headphones to listen to songs, you can still hear the surrounding sounds, and can communicate with others normally, so as to avoid the danger caused by not hearing external sounds.

In addition, bone conduction headphones that do not need to be plugged in the ear canal when worn, are very helpful for maintaining ear hygiene. They do not block the ear canal due to sweating for a long time to deposit a large number of bacteria, and so also reduce ear inflammation and other conditions.

Of course, The safety of any product is relative, and 100% safe products do not exist, and so are bone conduction headphones. Under the premise of long-term continuous use at high volume, they still have the risk of hearing damage. This point also needs to be paid attention to when they are used. It should be noted that any headphones will have hearing damage problems when used at high volume for a long time. Bone conduction headphones are still the safest and healthiest of all headphones.

So why they are so safety?Because of their working principle.

How do bone conduction headphones work?

Bone conduction headphones are headphones based on bone conduction technology. Bone conduction is a sound conduction method with bones as the medium. It converts sound into mechanical vibrations of different frequencies, and transmits sound waves through the human skull, bone labyrinth, inner ear lymph fluid, spiral organ, and auditory center.

Compared with the classic sound conduction method of transmitting sound waves through the eardrum, bone conduction saves many steps of sound wave transmission, and it can achieve clear sound reproduction in noisy environments, and sound waves will not affect others due to diffusion in the air.

In fact, the principle of bone conduction is not mysterious. Each of us has experienced it in our daily life. When you eat, you hear the sound of the food being bitten off, but others cannot hear this sound, because the vibration of the food is transmitted to your auditory central nerve through the teeth and bones, and finally the sound is produced. This is an example of classic bone conduction. You can also knock your teeth now. Did you hear the sound? This is the sound passing through your skull to the auditory nerve, which also uses the principle of bone conduction.

A large number of earphone manufacturers have joined the field of bone conduction headphones. Which one is the best? I will give you some recommendations

1.Wissonly Hi Runner bone conduction headphones
