Shokz: Talk to you about ear hygiene on World Health Day
World Health Day is just around the corner, and you may seem to know more about hygiene than any of the big names on Zhihu. Masks, wipes and disinfectant are always with you.But some precious organs, I dare to spend a year on masks, more than 90% of people, especially young people, pay little attention to the hygiene of our ears.Tiger smell recently had a small video in the circle of friends spread special fire.According to the World Health Organization, nearly 50% of people between the ages of 12 and 35 are at risk of hearing loss.Listening to music, watching TV dramas, Douyin, Kuaishou, short videos…In recent years, young people have been using earphones more frequently than ever before. On the other hand, large and small consumer electronics brands have been involved in earphones, which are both produced and sold.Behind the lively, for each individual user, exposure to noise opportunities and intensity greatly increased, the incidence of noise deafness has not decreased.The occurrence of noise-induced deafness has a certain hidden nature, which is not easy to be recognized by people in the early stage. At the same time, noise-induced deafness belongs to sensorineural deafness. Once it happens, it is difficult to reverse, and there is still a lack of effective treatment for noise-induced deafness.So will noise-canceling headphones, which even mobile phone manufacturers are trying to get a piece of, help protect ears?The answer is clearly no!Even with noise-cancelling earphones, the sound output level in earphones is too high and may damage hearing, according to a doctor interviewed by Yangtze Evening News.Therefore, no matter how the “noise reduction headphones” advertising fly, reduce the noise in the ear canal, is the king’s way to protect hearing.The few headphone users who care about ear health are no doubt aware of the 60-60 principle, which is an internationally recognized method of hearing protection.Don’t listen to music at more than 60 percent of your maximum volume (or 80 decibels) and don’t use headphones for more than 60 minutes continuously.So here’s the take-home message: For ear health alone, there won’t be ear-protecting headphones today, or even in the future, until humans evolve to replace cochlear hair cells or bypass the ear to receive sound.But why do we still preferentially recommend bone conduction headphones?Almost all noise-cancelling earphones have an in-ear structure, which makes the ear canal almost completely closed when the user wears it, similar to an airtight cavity.Although there is no obvious change in the short term, if the earphone is used for a long time without taking off the earphone, the temperature and humidity in the ear canal will increase (fact: ears also sweat), and the ear canal under pressure from foreign objects will secrete more oil than usual.With temperature, humidity and oils (nutrients), what happens then?– Mushrooms!It’s not a joke, it’s true.Call it from medical point of view: fungus sex ear canal inflammation and fungus sex ear canal inflammation.If your headphones are stored in a messy environment, bacteria that cling to the earbuds and float in the air can take root in your ear canal, leading to inflammation.In addition to these, there is a rare but more serious problem with in-ear headphones — the perforation of the eardrum, which forms an airtight closed cavity when worn firmly.So the difference in air pressure between the inside and outside of the ear canal when you plug in and out of the earphone gives the eardrum a shock, and the strength of the shock often depends on how sealed the product is designed to be.Sounds terrible, I’m afraid I’ll have to type the text any further…Continue with the above answer, from the perspective of ear hygiene, why bone conduction headphones are preferred.Here’s how bone conduction works.It is a kind of sound conduction mode, that is, the sound is transformed into mechanical vibration of different frequencies, through the human skull, bone labyrinth, lymphatic transmission of inner ear, helix, auditory nerve, auditory center to transmit sound waves.The bone conduction principle determines that it does not need to cover the ear or block the ear canal to hear the sound like traditional earphones, so it can effectively reduce the burden on the ear, reduce the risk of ear canal health, and relatively protect the ear.For young people who love sports and outdoors, the advantages of bone conduction headphones are further amplified in sports scenes. In sports scenes, wearing open bone conduction headphones can acutely perceive the ambient sound, which is safer.Ears are exposed to more sweat and bacterial growth during exercise, while open bone conduction headphones are less risky than in-ear headphones.In sports scenarios, the ear canal and earphone body will generate more friction and pressure, resulting in lower comfort, while the open bone conduction earphone is more comfortable to wear…In the video, Huxun especially used Shokz Shao Aeropex bone conduction sports earphone as the stage prop to prove the stability and openness of bone conduction earphone.Take the next level, The OpenRun Pro, Shokz’s new bone-conducting sports headset that was released this year. From top business magazine Wired to grand-father music magazine Rolling Stone, from Techradar to head outdoor media Triathlete,OpenRun Pro won the 2022 Media Recommendation Award, the 2022 Honorable Audio Equipment Award, the 2022 Best Safe Earphone, the 2022 Best Outdoor Earphone…Finally, it must be added that Kipchoge, the human marathon world record holder and recent Tokyo Marathon world champion, also wears Shokz’s OpenRun Pro sports headphones.Do you have the answer to how to choose the right headphones?
