Now the popularity of headphones, so that more and more people in life has been inseparable from headphones, and even some people think that wearing headphones at night when sleeping can not only improve the mood, but also isolate a certain amount of noise, sleep at night to wear headphones can improve the mood I really do not know, but what I know is that for a long time when sleeping at night when wearing headphones to listen to songs, it is likely to cause deafness. What the? Don't you believe it?
Just last week, the topic of #Women Wearing Headphones to Listen to Songs and Sleep Causing Deafness directly rushed to weibo's hot search, with 260 million reads and 17,000 discussions, which shows that the majority of netizens are still very concerned about this topic. The news in this topic shows that Ms. Fan, 33 years old this year, has not slept well due to neurasthenia. To this end, she thought of sleeping with headphones and listening to songs. In the past half a month, Ms. Fan found that her ears always had a "buzzing" tinnitus sound, and her hearing also deteriorated, and she was diagnosed with sudden deafness after seeking medical treatment.
Using headphones to listen to songs, why do you suddenly become deaf? Here you need to use a little knowledge from the biology class. In our human body, sound is transmitted mainly to the brain through ear hair cells. We often say that people who wear headphones often and after improper use of headphones will cause damage to hearing, most of the reasons for this is because the ear hair cells are damaged, ear hair cells are the most important component of everyone's ear, and are non-renewable and recoverable. Ear hair cells are very sensitive to large sounds, and sound is easy to cause damage to ear hair cells or even cause ear hair cell death. If the dead ear hair cells continue to increase, then it will not be deaf. Another is to wear headphones for a long time when sleeping at night, which will continuously increase the temperature and humidity in the ear canal, thus forming a hotbed for cultivating bacteria, and finally suffering from otitis media, and then hearing is impaired.
In fact, it can be found that people's hearing is very fragile, and a little carelessness will cause irreversible damage. And in recent years, news such as a certain person wearing headphones for a long time is deaf, experts give advice on the use of headphones, and more than 1.5 billion people are hearing impaired, and so on, which will directly rush to the hot search list. It shows that contemporary young people are paying more and more attention to their hearing health. Some merchants have also seen this potential market demand and launched a product called bone conduction headphones.
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.
Due to the characteristics of bone conduction headphones to transmit sound, the first advantage is obvious, bone conduction headphones can protect ear health to a certain extent. Bone conduction headphones do not go directly into the inside of the ear canal and do not clog the ears, solving the feeling that some people think that in-ear headphones are uncomfortable to wear. 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, but also to ensure that the ear canal is not contaminated 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 will be more secure for the user's ear health than traditional in-ear headphones.
However, if you want to improve ear hygiene when using headphones, you can also choose some bacteriostatic earbud sleeves to solve these problems. Bone conduction headphones also have an advantage: can allow users to perceive changes in the surrounding environment, bone conduction headphones open use characteristics, allow users to hear the surrounding sounds in real time, avoid the possibility of danger because of inability to hear the sound, greatly improving the safety of outdoor wearing headphones. Of course, to say more, now more and more true wireless headphones are equipped with a transparency mode that is getting better and better, so this point is slowly not counting as the advantages of bone conduction headphones.
Bone conduction headphones can protect hearing at the same time, the shortcomings of such products are also very obvious. First of all, the first disadvantage is the leakage of sound, in order to ensure the wearing comfort of the headphones, so most of the bone conduction headphones will not directly fit the skull, the unit will vibrate at the same time as the vibration produces sound, it will also vibrate with the headphone shell, and the shell will vibrate the air around it, resulting in the phenomenon of sound leakage, that is to say, people around you may hear more clearly than you. In fact, the shortcomings mentioned above are not called anything, at most it will cause some embarrassment, but as the saying goes, as long as you are not embarrassed, the embarrassment is someone else. The most obvious disadvantage of bone conduction headphones is the following one.
Listening to the sound feeling is the biggest pain point of the bone conduction headphones. Or because of the way the sound of the bone conduction headphones is transmitted, the sound is transmitted to the ear bonelets through the skin and cheekbones, and the sound transmission method is certainly not as direct as the in-ear headphones, so the separation of the bone conduction headphones in the sound. The sense of image and so on are completely inferior to traditional headphones, or you can see which headphones with the main sound quality use bone conduction technology. There is also a point, bone conduction headphones are susceptible to interference from the external environment, when the external noise is too noisy, when the ambient sound is greater than the headphone sound, it will lead to a great reduction in the listening effect, and may even not be heard. It's like when you're on the subway wearing bone conduction headphones and you find that you can't hear anything.
Bone conduction headphones can indeed protect hearing to a certain extent, but as a headset, the disadvantages are also obvious, that is, the listening experience. The main function of the headset is to "listen", and what is the use of the headphones with poor sound quality. In-ear headphones can cause hearing damage, we can completely change our own habits to avoid, such as: use antibacterial earbuds or use 60 minutes of headphones to rest for a while and so on. However, the problem of poor listening experience of bone conduction headphones cannot improve the sound quality of bone conduction headphones by changing their own use habits, so bone conduction headphones will only be a niche product after all.
