Which sounds are non-occupational noise?


Non-professional noise


Non-occupational noise is everywhere. With the improvement of living standards, the non-occupational noise that we face in our lives is gradually increasing. It is necessary to understand and prevent the harm of non-occupational noise.

What are the non-occupational noises?

Such as tractors, cars, ships, trains and other means of noise; the noise of fireworks and firecrackers in the Spring Festival; the sound of household appliances such as televisions, walkmans, radios, stereos; noise from entertainment venues such as KTV, disco, bars, concerts, etc. Often using a mobile phone for a long time to listen to music on a bus or subway, too loud a headphone volume will also have noise effects…


The key to improving the awareness of hearing protection is to improve the awareness of hearing protection. The following answers are mainly given in two aspects:

1 First, we must understand the physiological basis of hearing and understand how hearing is damaged. There are thousands of ciliated cells in the cochlea. The hair cells of our ears are divided into inner hair cells and outer hair cells, which are the most important effectors of hearing. There is a connection between the cilia, and a ciliary movement will drive other cilia to follow. Sometimes listening to a very loud concert feels that hearing has dropped. In a few days, I feel that my hearing has recovered. It is because the connection on the cilia grows slowly. If the cilia or cell body is dead, the hearing will recover. No more. And the death of this kind of cell is cumulative. For example, eating an ototoxic drug today may damage one or a small part of the hair cells. Tomorrow, I heard a very loud sound and sacrificed two. In this process, the hearing is slow. The decline but no obvious feeling, when the number of damaged cells reaches a certain level, it will suddenly feel the hearing loss, can not hear clearly. Because hearing damage to a certain extent will have irreversible consequences, the current hair cell damage has not found a way to effectively regenerate, so pay attention to hearing protection.

2 Understanding the long-term harmfulness of hearing loss The healthy hearing is a guarantee for high-quality life and work. In ancient times, because our human hearing warning function helped us to avoid the invasion of beasts, it is the instinct of human beings to survive better. This kind of warning requires binaural effect. If hearing loss occurs, when others are behind When we greet us, we can’t judge the position of the other party well, and listening to music will not feel so good again.

Some voices, even if they are heard, can cause communication problems if they don’t understand. When they reach old age, communication barriers may cause psychological problems such as autism and depression. At that time, it is very likely that they will use the hard-earned plan to travel. Buy hearing aids, which affects a higher quality of life.

Therefore, not paying attention to protecting your hearing when you are young will create a long-term hazard and increase the burden on individuals, families and society.

Its function is to generate a reverse sound wave equal to the external noise through the noise reduction system, and cancel the noise to achieve the noise reduction effect.

3 Note the influence of instrumental noise

For example, the sounds of instruments such as cymbals and erhus can produce very good music, but if you immerse them for a long time and the sound is too strong, ignoring the protection of hearing will also damage your hearing.

6 when noise is attached to other problems

For example, when flying, the noise will compound the air pressure when taking off, you can chew a piece of chewing gum, or swallow saliva, or drink some water to ease; the noise in the factory will be combined with toxic gas, noise and complex emotions will affect the hearing. Prevention can be achieved by reducing working hours, improving protection levels, and regular physical examinations.

7 seek medical advice in time to protect hearing health

Sometimes sudden depression is caused by stress, nervousness, excessive fatigue, etc. At this time, you should seek medical advice promptly. If you have a sudden deafness, it is very likely that you will recover as soon as possible. If the time is delayed, then the treatment may be restored. difficult.
