Whether it's a cyclist on campus, or a handsome man or a beautiful woman in a subway station or bus, many of them wear headphones to immerse themselves in their world. Places such as subways and buses are very noisy, and headphones need to be turned on. Loud sound for noise reduction. Before we know it, headphones steal our hearing and make our hearing loss. Headphone holster manufacturers analyze how headphones steal our hearing.

1. The small fans on both sides of the head are just a radio

The ear we often talk about generally refers to the pinna (the small fan on both sides of the head), which plays a very low role in hearing, like a radio. There is the external auditory canal deep in the auricle, and there are complex structures such as the middle ear and the inner ear deep in the external auditory canal, which are the main control room for hearing.

2. Use WeChat voice function to help you understand the principle of hearing

There are three necessary conditions for us to hear sound normally: the sound source is not far from the ear; the external auditory canal, middle ear, and inner ear are working properly; the area of the brain that analyzes sound is working properly. What you say is the sound source; the shell of the mobile phone is the pinna, and the microphone is like your middle ear, inner ear and other complex structures used to receive the sound source; the audio chip of the mobile phone is the auditory center in your brain, which can analyze the sound source . If your phone's microphone or audio chip fails, no matter how fancy the phone case is, it won't be worth half a dime.

3. High volume under the cover of noise is killing auditory cells

In a noisy environment, in order to suppress the noise of the environment, it is necessary to adjust the volume of the headphones to a very high level, and the high volume at this time is not as harsh as it is in a quiet time, which often makes us feel like we are in a state of ecstasy. But such volume can cause damage to the nerve cells in our inner ear.

4. Hearing cells cannot be regenerated, and one less is dead

Some people will say, don't be fooled, I don't feel any problems with my ears when I listen to headphones every day. This is because we have a certain number of auditory cells (about 10,000, but unfortunately it is a non-renewable resource, one less is sacrificed), if you listen to rock music with headphones on the bus, you will lose one or two hearing at most. Cells, doing this every day, it's hard to say how many auditory cells will work normally after a few years.

5. Those who completely ignore the volume prompts, please raise your paws

Now some Android-based smartphones have related protective tips. After plugging in the earphones, you cannot directly adjust the volume to 100% through the volume button. Additional confirmation and permission are required (and the iPhone has not been seen until 6.) With this design, fruit fans can reflect on this issue with Cook). Turn a blind eye to this prompt, and directly click on the confirmed classmate to come out and raise a claw.

6. Remember the 60-60-60 principle, which can effectively protect hearing

Of course, the essence of the headset comrade is still kind, as long as we don't dig out his dark side, he will only bring me enjoyment. Remember a principle when using it: 60-60-60, when you usually wear headphones to listen to music, the volume should not exceed 60% of the maximum volume; the continuous listening time should not exceed 60 minutes; the sound should preferably not exceed 60 decibels. This is the method I saw when I checked professional materials. I think it is good and recommend it to everyone.

If the earphones are broken, we can always replace them, but there is only one pair of ears, and if they are broken, there will be no more. We often say that the eyes are the window to the soul. Through the eyes, we can see the world, but the ears are also very important. Yes, with the right ear, we can hear all the joys and sorrows of the world. The manufacturer of the headphone holster recommends that you do not turn on the headphones too loudly and protect your ears.
