The process of noise pollution is actually a chronic poisoning process. It is generally believed that 40 decibels is the normal environmental sound for humans. Higher than this value, some harm may occur. When the noise intensity exceeds 100 decibels, it can cause hearing damage. Mild hearing impairment mainly manifests as mild tinnitus. If it develops further, it can affect speech and hearing to a certain extent, causing hearing difficulties in work, study, and life. Sometimes a strong noise can cause temporary total deafness in both ears, as well as severe tinnitus and dizziness. Being exposed to a noisy environment for a long time will have serious effects on the human nervous system, cardiovascular and cerebrovascular systems, digestion and endocrine systems.

1． nervous system. Damage to auditory cells, mild tinnitus, further develops, leading to hearing loss, which affects work, study and life.

2． Unstable blood pressure. It can induce high blood pressure, especially in patients with high blood pressure, and can further increase blood pressure. The chance of cerebrovascular accident is greatly increased

3. Digestive system. Being in a noisy environment for a long time can induce gastric ulcers, duodenal ulcers, etc.

4． heart. Can induce coronary heart disease, sinus arrhythmia, myocardial infarction, etc.

5. cancer. American medical scientists have proven through medical experiments that after 3 months, the cancer rate of mice exposed to noise interference increased by 60% compared with mice without noise interference./

6. Endocrine system. Long-term interference will cause endocrine disorders in the human body, lead to sperm abnormalities in men, and can cause infertility in men, and miscarriage and fetal malformations in women. In addition, noise can cause irritability, dizziness, fatigue, insomnia, forgetfulness, and muscle tension, thereby reducing learning and work efficiency and leading to an increase in work accidents.

Noise treatment on the roadside

1. The best way to deal with noise is to seal the windows tightly. Whether you have a single-layer window or a double-layer window, sealing is the most important thing. . The carrying capacity of a wooden barrel is determined by the shortest piece of wood, and the sound insulation effect is determined by the weakest link. From the current technical level, using plastic steel windows as a means of sealing is the most effective decoration solution. For users who have used aluminum alloy, they should ensure that the sealing strips of the aluminum alloy frame are intact. Relatively speaking, the sealing performance of aluminum alloy windows is worse than that of plastic steel windows.

2. After the window sealing is solved, the next step is to make it more sealed. After all, sound insulation does not just mean that it is sealed, but also depends on the sealing performance. Using insulating glass in plastic steel windows is a very effective method. Because the most noisy part is often the treble part, and treble propagates in a straight line, using glass can reflect most of it, and insulating glass can consume all the non-reflective parts. But be aware that profiteers will sell you untreated double-glazed glass as hollow glass.

3. Using thick curtains to consume part of the sound energy is also a simpler method, but of course it is not a very effective method.

4. For mid-bass sounds caused by vibration and friction, we can use carpets, fabrics and even sound-absorbing (sound-insulating) cotton to reduce their impact on the room. Installing rubber pads at the foot of the bed can also reduce certain vibrations. At the same time, the palm mattress used in the mattress is better than the spring-based Simmons, of course, not to mention the hard bed board.

5. Nowadays, some houses use lightweight bricks (hollow bricks) as exterior walls. These materials have poor sealing properties. If you are on the side of a highway and it has a great impact on you, you can also use it near the road. Make a sandwich of wooden squares (light steel) and paper-faced gypsum board filled with sound-absorbing (insulating) cotton on the wall, and then decorate the surface with wallpaper (of course, you can also use ordinary wall paint to treat the surface).

6. Of course, no matter how soundproofed you are, don’t forget to provide proper ventilation. An environment that is too closed is also unhealthy for sleep. Noise prevention should be done on the side facing the noise, and ventilation conditions should be properly maintained on the side facing away

Several measures to reduce noise

1. Close the sound source, Build sound insulation walls at the source to prevent noise from directly spreading outward.

2. Strengthen greening and plant trees on both sides of complicated roads to form barriers.

3. Install sound insulation facilities.

4. Lubricate the machine enough to prevent noise and protect the machine.

5. Add sound-isolating devices to your ears, such as good earplugs.

How to sleep well, you can take the following measures.

1. Close your eyes and enter the quiet method. After going to bed, first close your eyes, and then open them slightly to maintain some contact with the outside world. Although mental activities are still operating, the tension of sympathetic nerve activity has been greatly reduced, inducing the human body to gradually enter a sleepy state. .

2. Mingtiangu method. After going to bed, lie on your back with your eyes closed, cover your left ear with your left palm, cover your right ear with your right palm, and tap the back of your head with your fingers to make it hear a whirring sound. Bounce the number of times until you feel slightly tired. After stopping bouncing, slowly bring your head closer to the pillow, and then place your head naturally on both sides of your body, and you will fall asleep quickly.

3. Sleep induction. Listening to plain and rhythmic sounds, such as tapes of trains running, crickets chirping, dripping water, and the patter of spring rain, or musical hypnosis tapes, can help you sleep and can also establish conditioned reflexes to induce sleep.

4. Drink hot milk method.

According to research, drinking a cup of hot milk with sugar before going to bed can increase the secretion of insulin in the human body, increase the entry of amino acids into brain cells, and promote the human brain to secrete serotonin for sleep. At the same time, milk contains trace amounts of morphine-like substances, which have a calming and tranquilizing effect. This promotes the human body to fall asleep peacefully.

5. Suitable sleeping position. The sleeping position is of course suitable for comfort and can vary from person to person. However, it is better to sleep on your side. Health expert Cao Cishan pointed out in "Sleeping Tips": "Lie on your left side and bend your left foot, bend your left arm, support your head on your hand, stretch your right foot, and place your right hand between your right thighs. On the right side, The opposite is true for lying down. "This sleeping position is conducive to relaxing the whole body and sleeping peacefully.

6. If you are tired and have difficulty falling asleep, you may wish to eat fruits such as apples, bananas, tangerines, oranges, and pears. Because the aroma of this type of fruit has a sedative effect on the nervous system; the sugar in the fruit can inhibit the cerebral cortex and make it easier to enter a sleep state

Experts suggest that those who work in a noisy environment for a long time, People who live a healthy life should replenish some protein and foods rich in vitamin B in a timely and appropriate amount.
