Many young friends are under great pressure at work or like to wear headphones to listen to music in their spare time. If the method is not correct, especially in noisy places such as subways and buses, it is very likely to cause nervous deafness. This is because when the surrounding environment is noisy, people will unconsciously turn up the volume in order to listen to the music clearly. It is not surprising that nerve deafness is induced under the double stimulation of excessive volume and noisy noise. ?

It is worth noting that hearing loss caused by the interference of sound perception and nerve impulse transmission is called induced neurological deafness, which does not mean that hearing loss is called deafness. People's hearing range is very large. Even if their hearing is damaged, many people will not notice it as long as it does not affect the communication and dialogue. Therefore, the auditory "killer" is generally mild and the damage process is silent.

Put on headphones and master the "60 Principles". People who often wear headphones, especially those with built-in headphones, should master the 60-60-60 principle, that is, when listening to music, the volume should not exceed 60% of the maximum volume, the continuous listening time should not exceed 60 minutes, and the external sound should not exceed 60 decibels.

Many people have no idea about decibel value. Let me give you a few examples for your reference: ordinary volcanic eruption180dB, airplane takeoff130 ~140dB, chainsaw working10dB, tractor starting100dB, and very noisy road 90dB.

In addition, try to listen to music in a quiet environment, and use protective earplugs in a noisy environment, which can be bought in general labor insurance stores, which can effectively block some noise and protect hearing.

If you are asked what your ears do, it is estimated that nine times out of ten you will answer and listen to things. But you should know that Chinese medicine believes that the ear is the reflection area of various viscera, and most diseases of the human body can be reflected in the ear. Keeping your ears healthy often will achieve the effect of health preservation.
