I. How about bone conduction earphones
First of all, on the whole, bone conduction earphones are just a kind of earphones with obvious advantages and disadvantages. If you need a Headphones, to listen to some audiobooks, or something else that doesn’t require much sound quality. And you need to use headphones in a noisy environment, or in an environment where you are talking to people. Then, it is recommended that you buy bone conduction headphones.
1. Sound quality
In terms of sound quality, the sound quality of bone conduction headphones can only be said to be very general. Hundreds of bone conduction headphones, the sound quality is equivalent to the kind of poor speaker. Therefore, those who pursue sound quality can give up the option of considering bone conduction headphones.
Therefore, if you choose to listen to music, etc., and have higher requirements for sound quality, it is not recommended to buy bone conduction headphones.
2. Convenience/safety aspects
The biggest advantage of bone conduction headphones is convenience and safety. Because the sound is transmitted through the jawbone, and the ears are not covered. Therefore, when driving, running, or cycling, it is safer than traditional headphones. Moreover, when talking with people, you don’t need to take off the headphones, you can listen to songs and talk to people at the same time.
Therefore, bone conduction earphones are most suitable for use when commuting to and from get off work, when running or cycling on the street.
3. Comfort
Since bone conduction headphones transmit sound through vibration, as long as you use bone conduction headphones Feel the vibration. The louder the volume of the headset, the stronger the vibration.
If you turn on the volume at a high volume and wear bone conduction headphones for a long time, it will inevitably feel uncomfortable. But it’s also about the environment you’re in, and what you’re listening to.
Bone conduction headphones, although they will not damage the periosteum, will damage other parts of the hearing, so it is recommended that even if you use bone conduction headphones, do not turn on the maximum volume.
4. Volume
This aspect is the biggest advantage of bone conduction headphones, but also its biggest disadvantage. On the one hand, it does not affect you talking to people while listening to music, and this also means that once you are in a noisy environment such as on the street or in a subway station, the volume of bone conduction headphones is often easily covered. But if you turn on the sound of the bone conduction headphones to the maximum, you will often feel a little uncomfortable after listening for a long time.
In a particularly noisy environment, bone conduction headphones are also useless, so don’t use them at this time.
5. Battery life
Generally speaking, the higher the volume, the greater the power consumption. If you turn on the volume at a relatively high volume and listen for a long time, you will usually need to charge it twice a day. If you hear less, it will vary from person to person.
6. Wearing aspects
Wearing bone conduction headphones does not affect wearing glasses and goggles. However, it will affect the ear protectors or ear caps worn in winter, and there will be air leakage problems.
Generally speaking, bone conduction headphones are suitable for people who are not so cold in weather, use headphones to listen to audiobooks, etc., and who do not require high sound quality, often in noisy environments. use.
2. Does bone conduction earphones affect hearing?
True bone conduction earphones can only protect hearing. any hazard. The structure of the human ear is composed of the external auditory canal, tympanic membrane, auditory ossicles, cochlea, and auditory nerve. Under normal circumstances, whether it is ordinary wired headphones, or Bluetooth headphones and noise-cancelling headphones, they are essentially “air conduction headphones”, that is, the air in the external auditory canal is the main sound transmission medium, and only a small part of the sound waves pass through. Bone conduction. In the air conduction process, the tiny speakers of the earphone vibrate, and through the air in the external auditory canal, the sound waves are transmitted to the tympanic membrane, the ossicles, the labyrinth of the inner ear bone and other parts in turn. The vibration of the internal and external lymph fluid in the inner ear helps the spiralizer to complete the perception of sound. After being transmitted to the auditory nerve, the auditory nerve generates nerve impulses and presents the signal to the auditory center. After comprehensive analysis by the cerebral cortex, we “hear” the sound. Note: The ossicles are the smallest bones in the human body, three for each ear. The ossicular bone consists of the malleus, incus and stapes, most of which reside in the upper tympanic cavity, and are connected by ligaments and joints to form the ossicular chain.
The biggest unique feature of bone conduction headphones is that sound waves do not pass through the air in the external auditory canal and tympanic membrane, but directly use the human bone structure as a sound transmission medium. When using, we need to use the sound source of the bone conduction earphone against the skull behind the ear. When the sound source vibrates, it will drive the skull to vibrate together, so that the sound waves are introduced into the skull. The sound waves then pass through the skull, bypassing the external auditory canal and eardrum directly to the ossicles. The auditory ossicles then guide the sound waves into the bony labyrinth, so that the sound information is transmitted to the cochlea and auditory nerve. In this way, we have successfully used bone conduction technology to hear the sound, which represents a bumpy bone conduction headset.
Bone conduction is two ways of moving and squeezing, the sound waves are radiated into the ear through the cerebral cortex and bones, and the two work together to stimulate the spiral organ in the ear to cause hearing, no need to vibrate the eardrum like a horn. The sound, and the timbre is very clear and silky into the ear, those with damaged eardrums can use various audio equipment normally, and those with normal hearing can effectively protect their hearing. There is no fever, no pain, no tinnitus, no dizziness when using the ear.
