Now the popularity of headphones, so that more and more people in life has been inseparable from headphones, commuting on the road to wear headphones, emo also wear headphones, sports also like to wear headphones to stimulate their potential, and even some people like to wear headphones when sleeping at night. Wearing or using in-ear headphones for a long time will definitely cause health problems, and in recent years, so-and-so long time wearing headphones deaf, experts give headphones advice, more than 1.5 billion people hearing loss and other such news will directly rush to the hot search list. It shows that contemporary young people are paying more and more attention to their hearing health. It can also be seen that in-ear headphones do cause some irreversible and serious damage to human fragile hearing.
So why does wearing in-ear headphones cause hearing loss or deafness? Here, we need to apply some biological knowledge. In the human body, a very complex biological system, the human body mainly through the ear hair cells to perceive sound, but when wearing ear headphones, the ear canal will form a relatively closed space, sound waves will directly act on the ear hair cells, and the larger volume will also have an irreversible impact on the ear hair cells, we need to know that the ear hair cells are the most important part of everyone's ear, and are non-renewable and recoverable. Ear hair cells are very sensitive to large sounds, and sound can easily cause damage to ear hair cells or even cause cell death. Dead ear hair cells continue to increase, so hearing is also impaired. In addition, many people like to wear in-ear headphones to listen to songs when exercising or sleeping or use the passive noise reduction function of in-ear headphones to isolate part of the noise, but when sleeping and exercising, the ear canal will be directly blocked, resulting in an increase in temperature and humidity in the ear canal, further forming a hotbed for cultivating bacteria, and finally suffering from otitis media, which will also cause irreversible damage to hearing.
Now people are paying more and more attention to ear health, and they have slowly learned about the drawbacks of some in-ear headphones, so there are more and more bone conduction headphones in the headphone market now. In fact, bone conduction is a very common physical phenomenon, when you bite your teeth, your head can hear the sound, this is the most common bone conduction. The principle of bone conduction headphones is similar, headphones produce vibrations, but this vibration is not transmitted to the ear through air, but through the temporal bone of the head directly conducts the vibration to the auditory nerve, and the brain processes the received information to produce hearing, this process does not need to pass through the ear eardrum, directly transmitted from the bone to the brain.
Thanks to the nature of bone conduction headphones to transmit sound, bone conduction headphones have many inherent advantages over in-ear headphones. Bone conduction headphones do not go directly into the ear canal and do not block the ears, which solves the disadvantage of wearing discomfort in in-ear headphones, or that in-ear headphones are more likely to damage hearing. The vibration unit of the bone conduction headphone acts directly on the cheekbones, avoiding the damage caused by the long-term use of traditional headphones to the ear ear eardrum, which can effectively protect the hearing. And the open use of the scene, not only to ensure that the ear canal is not polluted by sweat and human secretions, and will not produce high temperature and high humidity environment to promote the growth of bacteria. Therefore, bone conduction headphones are more friendly to ear health than in-ear headphones.
In addition, the open listening structure of bone conduction headphones can also allow users to listen to music while also hearing the sounds of the surrounding environment and perceiving changes in the surrounding environment, thereby avoiding some dangerous situations and greatly improving the safety of outdoor headphones. Therefore, bone conduction headphones will be more suitable for outdoor sports such as running and cycling than in-ear headphones, which greatly improves the safety of outdoor sports.
As far as the types of headphones currently on the market are concerned, bone conduction headphones must be more suitable for wearing products when exercising. So bone conduction headphones have no disadvantages? In fact, there are still some, bone conduction headphones rely on vibration to produce sound, so there will be a certain leakage phenomenon, and also because of the way bone conduction headphones work, the sound quality of such headphones will be weaker than the traditional in-ear headphones, but these compared to the safety of sports, these shortcomings seem to be ignored.
The purchase of bone conduction headphones is also a science, but today is limited by the limitations of the length of the article, and can not teach you how to choose and buy bone conduction headphones. Therefore, recommend two very cost-effective products to everyone, when you don't know what to buy, choose one of the following two products, you will certainly not be wrong.
