1. Auditory cells are damaged, and tinnitus is mild, which further develops, leading to hearing loss and affecting work, study and life.
2. Blood pressure is unstable. It can induce hypertension, especially in patients with hypertension, and can further increase hypertension. The probability of cerebrovascular accident is greatly increased.
3. Digestive system. Long-term exposure to noise can induce gastric ulcer and duodenal ulcer.
4. Heart. Can induce coronary heart disease, sinus arrhythmia, myocardial infarction and so on.
5. Cancer. American medical scientists have proved through medical experiments that the canceration rate of mice disturbed by noise after 3 months is higher than that of mice without noise interference by more than 60%/.
6. Endocrine system. Long-term interference will lead to endocrine disorders, abnormal male sperm, male infertility, female abortion and fetal malformation. In addition, noise can make people feel fidgety, dizzy, tired, insomnia, forgetfulness and muscle tension, thus reducing study and work efficiency and leading to an increase in work accidents.
Roadside noise treatment
1. The best way to deal with noise is to close the window. Whether you have a single window or a double window, sealing is the most important thing. The bearing capacity of a barrel is determined by the shortest sawdust, and the sound insulation effect is determined by the weakest link. From the current technical level, it is the most effective decoration scheme to use plastic steel windows as sealing means. For users who have adopted aluminum alloy, it is necessary to ensure that the aluminum alloy frame sealing strip is intact. Relatively speaking, the sealing performance of aluminum alloy windows is worse than that of plastic steel windows.
2, the window seal is solved, the next step is to make it more sealed, after all, sound insulation does not mean sealing, but also depends on sealing performance. It is a very effective method to use insulating glass in plastic steel windows. Because the loudest part is often the high-pitched part, and the high-pitched part travels in a straight line, most of it can be reflected by the glass, and the non-reflective part can be consumed by the insulating glass. However, it should be noted that profiteers sell you untreated double glass as insulating glass.
It is also a simple way to use thick curtains to consume some sound energy, but it is certainly not a very effective way.
We can use carpets, cloth and even sound-absorbing cotton to reduce their indoor influence. Rubber pads at the foot of the bed can also reduce vibration. At the same time, mattresses with palm pads are better than Simmons with springs, not to mention hard beds.
5. Now some houses use light bricks (hollow bricks) as external walls, which have poor sealing performance. If your roadside has a great influence on you, you can also make a sandwich of wood square (light steel) and sound-absorbing (sound-insulating) cotton with gypsum board on the wall near the road, and then decorate the surface with wallpaper (of course, you can also treat the surface with ordinary wall paint).
6, of course, no matter how to do sound insulation, don't forget proper ventilation, too closed environment is as unhealthy as sleep. Noise should be prevented on the side facing noise, and ventilation should be properly maintained on the side far away from noise.
Several measures to reduce noise
1, turn off the sound source, and build a sound insulation wall at the sound source to prevent the noise from spreading directly to the outside.
2. Strengthen greening and plant trees on both sides of complex roads to form barriers.
3. Add sound insulation facilities.
4。 Lubricate the machine sufficiently to prevent noise and protect the machine.
5. Put a sound insulation device in the ear, such as a good earplug.
How to sleep well can take the following measures.
1, close your eyes and go into silence. After going to bed, close your eyes first, then open your eyes slightly to keep in touch with the outside world. Although mental activity is still in operation, the tension of sympathetic nerve activity has been greatly reduced, which induces the human body to gradually enter a sleepy state.
2. Ming and ancient laws. After going to bed, lie on your back and close your eyes, 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 the whirring sound. The number of bounces until you feel slightly tired. After you stop bouncing, your head will slowly get close to the sleeping pillow, and then it will naturally be placed on your sides, and you will soon fall asleep.
3. Sleep induction. Listening to plain and rhythmic sounds, such as the sound of trains running, the chirping of crickets, the dripping sound and the sound of falling spring rain, or music hypnotic tapes, is helpful to sleep and can also establish conditioned reflex to induce sleep.
4. Drink hot milk. Drinking a cup of hot milk with sugar before going to bed can increase the secretion of insulin, increase the entry of amino acids into brain cells and promote the brain to secrete serotonin for sleep. At the same time, milk contains a small amount of morphine-like substances, which has the effect of calming and calming the nerves, thus promoting the human body to sleep peacefully.
5, the correct sleeping position. Of course, the sleeping position is comfortable and can vary from person to person. However, it is better to sleep on your side. Cao Cishan, a health care expert, pointed out in Sleep Tactics: "Lie on the left side and bend your left foot, bend your left arm, hold your head with your hand, stretch your right foot, and put your right hand between your right thighs. The right bit is the opposite. " This sleeping position is conducive to relaxing the whole body and sleeping soundly.
6. If you are tired and have difficulty sleeping, you might as well eat apples, bananas, oranges, oranges, pears and other fruits. Because the fragrance of this fruit has a calming effect on the nervous system; The sugar in fruit can inhibit the cerebral cortex and make it easy to fall asleep.
Experts suggest that people who work and live in noisy environment for a long time should supplement some protein and foods rich in vitamin B in a timely and appropriate way.
