Why do my ears feel bad when I take the subway
The opening of the subway has facilitated everyone's travel, but several readers have sent questions to the Qian Bao encyclopedia:
Why do my ears feel uncomfortable when I ride the subway?
Netizens said:
Yesterday on the subway, I felt a little tinnitus, I don't know if the 4-month-old baby can take the subway, will it have any impact?"
Another netizen usually takes the subway to work and likes to listen to music with headphones on the way:
"I always have a faint feeling that my ears are a little swollen. I used to wear headphones to listen to music when I took the bus, but it didn't seem so uncomfortable. Is it something to do with taking the subway?"
Why do my ears feel bad when I take the subway
● Taking the subway is a bit like flying, which can cause discomfort in your eardrums
Like the airplane, the subway itself is a relatively closed environment. When the train starts, the speed is faster, and the air pressure of the whole subway space is low, which will have a difference with the air pressure of the human body, resulting in the human eardrum invagination.
Therefore, it is normal for some passengers to have ear discomfort when taking the subway.
Try to relax on the subway.
If you feel uncomfortable with the eardrum, you can hold your nose after you leave the station, pump hard, and drum the eardrum to balance the pressure difference between inside and outside the body; Opening your mouth or swallowing can also help.
● Is it okay for a baby to take the subway
In theory, a 4-month-old baby can ride the subway without any discomfort.
However, the newborn baby resistance is relatively weak, it is recommended to go to the subway and other public places as little as possible, easy to cause cross infection.
When taking the baby on the subway, it is best to let the baby's mouth open, which is conducive to relieving the discomfort caused by the oppression of the eardrum.
● Listening to music on the subway hurts your ears the most
When taking the subway, listening to earplug music is the most harmful to the ears, and may even cause deafness in the long run. This is because the subway is noisy and people unconsciously turn up the volume in order to hear the music clearly.
When headphones are plugged into the ear, the high-intensity sound will impact the eardrum, causing hair cell damage; The pulsing noise is also the most damaging to hearing.
Excessive volume and loud sounds stimulate the ears, which can lead to sensorineural deafness over time.
When the volume of the human ear is more than 85 decibels, more than 60 minutes will cause auditory fatigue; When the volume reaches more than 110 decibels, it is enough to cause the hair cells of the human inner ear to die.
In real life, the volume output of headphones is generally about 84 decibels, and some high-frequency ranges can reach 120 decibels, while the volume of in-ear headphones (earbuds) is 5.5 decibels higher than that of ordinary headphones.
The process of hearing loss is silent and progressive, and may not be noticed for a short time.
If you particularly like to listen to music with earplugs, it is likely that you will have a pair of aging ears in advance of a few years.
