Netizen: my grandfather used to be a soldier. He was an artillery soldier in the army. Now he is over 70 years old. But now his hearing loss is very serious. He can’t hear us a lot. It seems that his hearing is worse than other people of the same age. What’s the matter?

Expert: because the sound is very loud when the shell explodes and is launched. If we are in such an environment for a long time, it will cause damage to some structures of our ears, so we will have serious hearing loss in our later years.

Netizen: my uncle seems to be a little deaf. I can only hear when I speak with him loudly. I can only hear when I watch TV very loudly. He used to work in a textile machinery factory.

Expert: because the textile machinery factory is full of mechanical sound all day, and the mechanical sound is relatively loud, and people are in a relatively loud sound for a long time, which will cause great damage to our hearing, so your uncle is caused by working in a noisy environment in the machinery factory for a long time.

Netizen: I am a young man, I often wear earplugs to listen to MP3, but now my friend says to me, talk to me louder than usual, and I listen to music louder than others. They suspected that I had a hearing problem. They asked me to check it. Is it really a hearing problem like me.

Expert: it is not a good habit to often wear earplugs to listen to music. As time goes on, it will cause damage to hearing. The best way to listen to music is not to wear earplugs. If you have to wear earphones, you should also wear earphones. The time of listening to music should not exceed 60 minutes, and the volume of listening to music should not exceed 60% of the maximum volume. As you said above, it may be that your hearing is faulty. It is recommended that you go to a professional organization to check it, or come to our marine hearing department to check it.

There are many patients like the above. We just excerpted three exchanges between netizens and experts to present to you. From the above exchanges, we can easily find that these people have a common feature of deafness, that is, they are all in the noise environment before. Therefore, noise is one of the important causes of deafness.

Now noise has become a kind of world public hazard, one of the three social public hazards in the world. It is often in high-intensity noise, which will cause great harm to hearing. So we should try our best to avoid appearing in the noisy environment, and try to move in the quieter environment. What level of noise is defined as harmful noise? Continuous noise with intensity over 85 decibels and impulse noise with intensity over 140 decibels are harmful noise. The places that make these harmful noises are usually: industry, transportation, entertainment, firecrackers, military and so on. The noise damage to human body is not only hearing, but also nerve, cardiovascular, digestive, endocrine and so on.

The loss of hearing caused by noise can be divided into two types: one is temporary – reversible transformation; the other is permanent – irreversible. For reversible transformation of hearing loss, we should actively take measures to restore our own hearing, but don’t think that we can restore hearing, so we don’t pay attention to this kind of hearing loss. If the next time is irreversible hearing loss, then you will never return to normal hearing, so we should protect our own hearing and do a good job in hearing care under any circumstances.
