Which sounds are unprofessional?

According to statistics, there are 27.8 million hearing disabled people in China, and more than 300000 new hearing disabled people are added every year, making it the most hearing disabled country in the world. Research shows that noise is one of the important reasons for hearing disability. Today, Jinghao hearing analyzes the harm of non occupational noise to our hearing from a professional point of view, and shares practical ways to protect our hearing.

One

With the improvement of living standard, we are facing more and more non professional noise. It is necessary to understand and prevent the harm of non professional noise.

What are the non professional noises?

For example, the noise of tractors, cars, ships, trains and other means of transportation; the noise of setting off fireworks and firecrackers during the Spring Festival; the noise of television, Walkman, radio, stereo and other household appliances; the noise of KTV, disco, bar, concert and other places of entertainment; the noise can also be generated if the earphone volume is turned too high for a long time by using mobile phone, listening to music on the bus or subway Affect…

How to improve the awareness of hearing protection is the key to improve the awareness of hearing protection

First of all, we need to understand the physiological basis of hearing and 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. They are the most important effectors to produce hearing. There is a connection between the cilia. One ciliated movement will drive other cilia to follow. Sometimes I feel hearing loss when I listen to a very loud concert. I feel hearing is restored in a few days. In fact, the connection on the cilia grows slowly again. If the cilia or cell bodies die, the hearing cannot be restored. Moreover, the cell death is cumulative. For example, taking an ototoxic drug today may damage one or a small part of hair cells, and listening to a very loud voice tomorrow will sacrifice two more. In this process, the hearing is slowly decreased but there is no obvious feeling. When the number of damaged cells reaches a certain degree, it will suddenly feel the hearing loss, and the hearing is not clear. Because hearing damage to a certain extent will have irreversible consequences, at present, no effective regeneration method has been found for damaged hair cells, so attention should be paid to hearing protection.

It is a guarantee of high quality life and work to understand the long-term harmful and healthy hearing caused by hearing loss. In ancient times, because of our human auditory early warning function, which helps us to avoid the invasion of beasts, it is the instinct for human beings to survive better, and this early warning needs the binaural effect. If there is hearing loss, when others greet us from behind, we can’t judge each other’s position well, and listening to music will no longer be so pleasant.

Even if some voices are heard but cannot be understood, communication barriers will occur. In old age, communication barriers may cause psychological problems such as autism and depression. At that time, it is likely to use the hard-earned money from planned travel to buy hearing aids, thus affecting a higher quality of life.

Therefore, not paying attention to hearing protection when young will cause a long-term harm and increase the burden of individuals, families and society.

Small ways to prevent non occupational noise ① pay attention to volume control when using headphones

When using headphones to listen to music, pay attention to grasp the time and control the volume. The time shall not exceed 60 minutes, and the loudness shall be controlled below 60dB.

② use hearing protection equipment

When using earphones on vehicles, active noise reduction earphones can be used. Its function is to generate reverse sound waves equal to the external noise through the noise reduction system, so as to cancel the noise and achieve the effect of noise reduction. At present, there are a lot of headphones on the market, and many people buy and use them.

③ pay attention to the influence of instrumental noise

For example, the sound of gongs, erhu and other instruments can produce very beautiful music, but if they are immersed in it for a long time, and the sound is too strong, ignoring the protection of hearing will also damage hearing.

④ increase the sensitivity to sound

It’s like when it’s cold, we will consciously add clothes. When listening to the sound, if it feels a little loud or uncomfortable, we should also consciously protect it. We can put some cotton in our ears, or we can put toilet paper without cotton.

⑤ when listening to the phone

When using the mobile phone, try to keep the mobile phone far away from the ear to reduce the side effects caused by electromagnetic wave; for those who have the habit of answering the phone for a long time, it is recommended to turn the mobile phone to the handsfree state or use the headset properly.

⑥ when the noise is attached to other problems

For example, when taking off and landing in an airplane, the noise will compound the air pressure problem, which can be alleviated by chewing a piece of gum, swallowing saliva, or drinking some water; the noise in the factory will compound the toxic gas, the noise compound emotions and other problems will have an impact on the hearing, which can be prevented by reducing working hours, improving the level of protection, regular physical examination and so on.

⑦ see a doctor in time to protect hearing health

Sometimes sudden deafness will be caused by problems such as high pressure, mental tension, and excessive fatigue. At this time, timely medical treatment should be carried out. If the sudden deafness is recovered as soon as possible after treatment, it may be more difficult to recover after a long time delay. In addition, when we feel hearing loss, ear swelling, ear tightness, tinnitus, earache and other symptoms, we also need to see a doctor in time.
