How to effectively eliminate the harm of road noise to the human body 10

The hazards of car noise.

The harm of noise is many, noise not only causes great interference to people's normal life and work, affects people's conversation, thinking, affects people's sleep, makes people irritable, slow to respond, reduces work efficiency, distracts, causes work accidents, and more serious is that noise can damage people's hearing and health. The greater the intensity, the higher the frequency, the longer the duration of the noise, and the less personal endurance, the more serious the damage. Statistics show that noise below 80dB(a) does not cause noise-induced deafness; 80db(a) 85db(a) noise can cause minor hearing damage; Noise of 85dB(a) and 100dB(A) can cause a certain amount of noise-induced deafness; Above 100dB(A), a considerable amount of noise-induced deafness can occur.

In the case of unprepared people, extremely high intensity of violent noise (such as when suddenly firing a cannon**) can cause permanent loss of hearing in an instant, that is, violent deafness, at this time, the person's hearing organs will suffer severe trauma.

The impact of traffic noise on human health is manifold. Noise acts on the central nervous system of people, causing the balance of excitability and inhibition in the cerebral cortex to be out of balance, resulting in abnormal conditioned reflexes and damage to cerebral vascular tone. These physiological changes can be restored to their original state in the early stage, but over time, they will lead to pathological changes, causing people to have symptoms such as headache, brain bloating, tinnitus, insomnia, memory loss, and general fatigue.

If a pregnant woman rides in a noisy vehicle for a long time, the noise will affect fetal development by acting on the central nervous system.

Noise also has serious adverse effects on the digestive system and cardiovascular system, causing indigestion, loss of appetite, nausea and vomiting, which leads to an increase in the incidence of gastric diseases and gastric ulcers, and significantly increases the incidence of hypertension, arteriosclerosis and coronary heart disease than normal. Noise can also have adverse effects on the visual organs.

Automobiles have brought modern material civilization to the world, but at the same time, they have also brought social problems such as environmental noise pollution. As an important evaluation index of car ride comfort, car noise will also reflect the design level and process level of the manufacturer to a large extent. Therefore, controlling car noise to the lowest level is also the direction pursued by car designers.

Door and window seals seal the gap between your door, window and window frame. Thus greatly improving the sound insulation effect of doors and windows.

There is an earplug that protects the ears.

Noise can be seen everywhere in our lives, but whether it is home improvement noise, car noise or bar noise, once it exceeds 85 decibels, then, it is easy to damage hearing and vision. So,Noise controlWhat are the methods? Let's take a closer look:

Noise controlWhat are the methods and what are the dangers of noise to the human body? I hope I can give you some help and inspiration.

Noise controlWhat are the methods:

1. Use sound-absorbing materials in home decoration.

2. It's best not to put electrical appliances together.

3. Raising more flowers can eliminate some noise.

4. Noise will consume a large number of amino acids and vitamin B in the body, resulting in the weakening and imbalance of some functions, so it is necessary to eat more things containing amino acids and vitamin B, so as to avoid the harm of noise.

5. Bring earplugs to avoid noise interference.

What is the harm of noise to the human body:

1. Impaired eyesight.

First of all, the harsh noise can affect people's hearing organs, and in severe cases, it can even cause hearing loss. In addition, the ears and eyes are closely connected, so if hearing is affected, then vision will also be affected.

2. Affect sleep.

Secondly, noise will also affect sleep, once the noise reaches 40 decibels, it can wake up 10% of people, when the noise reaches 60 decibels, it can wake up 70% of people, if it goes on for a long time, it will cause insomnia, lack of energy, memory loss and other problems.

3. Hearing damage.

Again, noise can damage hearing, according to relevant information, if a person continuously hears the sound of motorcycles, then after 8 hours of hearing damage, if a person plays in a rock ** hall, then after 30 minutes of hearing damage, if a person stays in more than 80 decibels of noise for 1 hour, the chance of deafness will reach 50%.

4. Affect the system.

Finally, according to relevant surveys, for every 1 decibel increase in noise, the incidence of hypertension increases by 3%. In addition, noise can also affect the body's nervous system, making people feel irritable and angry. If you work in a noisy environment for a long time, it can also cause neurasthenic syndrome.

It is understood that if the noise is below 85 decibels, there will be no harm, and if the noise is above 85 decibels, it may be dangerous, and if you work at 90 decibels, then the probability of deafness will be greatly increased.

What are the methods and what are the dangers of noise to the human body are introduced here, noise is very harmful to the human body, therefore, we should pay attention to protection in daily life, so as to protect hearing and vision from damage.

Whether it's indoor or outdoor, if it's indoors, you can put more green plants indoors, they have a certain effect of absorbing noise, and they can also purify the indoor air.

There is no ready-made **, you have to collect information!

1. What are the hazards of noise?

The harm of noise to sleep: sudden noise at 40 decibels, can wake up 10 people, and when it reaches 60 decibels, it can wake up 70 people.

Noise damage to hearing: Noise can cause tinnitus, deafness and hearing damage, and when it exceeds 55 decibels, it feels noisy. Long-term exposure to noise above 85 decibels is associated with a prevalence of 21 after 40 years.

What is the physiological harm of noise? Noise can cause nervous tension, irregular heartbeat, increased blood pressure, and high noise environment, which will make some women's sexual dysfunction, menstrual disorders, and higher miscarriage rates in pregnant women.

Noise harm to children: Noise can hinder children's intellectual development, and children in noisy environments have lower mental development than children in quiet environments20.

2. Living next to an elevated road (road), why is there noise when the doors and windows are closed?

Because the main reason why doors and windows are not soundproofed is the tightness of the window frame and the sash itself, and secondly, the thickness of the glass, so you must transform your doors and windows into soundproof doors and windows.

3. How to insulate doors and windows? What are the other benefits of sound insulation?

There are five steps to soundproofing doors and windows:

a. Seal the slideway; b. Sealing the glide path; c. Install high-quality sealing strips; d. Installing seals;

e. Seal each ventilation point. Single-layer glass plus sound insulation film, insulating glass plus sound insulation sealing strip.

Benefits after noise elimination:

1. Power saving: users with air conditioning can save about 10% of electricity per month;

2. Dustproof: The soil cannot be seen on the window sill after sealing.

3. Insulation: In winter, under the same conditions, the indoor temperature difference before and after sealing is 3-6 degrees.

4. Noise reduction: For users living in downtown areas or on the side of elevated roads, the noise can be reduced by 3-5 decibels (comparison before and after the renovation of the same test point indoors), and a noise reduction of 3 decibels means that the volume felt by the human ear has been reduced by half.

This network night tour, collect some information!

<>1.Check the environment. The younger your baby is, the smaller the noise range it can tolerate.

Carefully check the environment to see if the noise is louder than your baby's tolerance. Noise prevention at home. Give the baby a separate room to rest, and adults should not play loudly for a long time at home.

Those who have a pet dog at home should be trained not to bark at will. If the baby is affected, it can be placed in temporary foster care. In order to give the baby early education, some mothers will put a lot of ** for the baby, but remember to choose a gentle ** and control the time of **, generally no more than 20 minutes at a time.

2.Control on the sound source. To reduce noise from sound sources, the industrial and transportation industries can choose low-noise production equipment and improve production processes, or change the way noise sources move, such as damping and vibration isolation measures to reduce vibrations in solid sounders.

Control during noise propagation. In terms of sound transmission methods, reduce noise (in the process of propagation) to control the propagation of noise, change the propagation mode of noise already emitted by sound sources, such as taking measures such as sound absorption, sound insulation, sound barriers, vibration isolation, and planting more trees, and reasonably plan the layout of cities and buildings.

3.Attenuates noise to the human ear. When noise protection cannot be taken for the recipient or the recipient organ in terms of the sound source and transmission route, or the acoustic measures still do not achieve the expected effect, protective measures should be taken for the recipient or the recipient organ, such as earplugs, earmuffs or helmets and other ear protectors of workers who are exposed to long-term occupational noise.

It is also relatively easy to use thick curtains to consume some of the sound energy. It is known that the sound insulation capacity of soundproof curtains is about 20 decibels. Using soundproof curtains not only reduces some noise pollution, but also controls the light.

We can use carpets, fabrics, and even sound-absorbing cotton to reduce the impact of vibration and friction on the room. Adding rubber pads to the foot of the bed can also reduce vibration. Double glazing can be installed for sound insulation.

The double-glazed glass has a sound insulation effect of about 40%, and the air layer in the middle has a certain shock-absorbing effect, which can weaken the vibration transmitted to the inner glass, so as to achieve the sound insulation effect of the double-glazed glass, thereby greatly reducing the noise transmitted to the room.

Choose a confined space, the sealing of the glass should be good, the wall can choose soundproof materials, if you can also add soundproof cotton in the later stage, the tables, chairs and benches should be handled gently to avoid dragging.

1.Reduce car horns. 2.Increase the greenery of the city and plant greenery on both sides of the road. 3.Avoid loud noises in public places and avoid turning up electronic devices to maximum sound.

Try not to go to places with high noise, let yourself stay in a quiet place, you can also wear earplugs, you can install noise prevention equipment, you can avoid noise.

You can wear headphones, earbuds, add some soundproof equipment, change to a soundproof glass, and control the noise source.

1.Rough walls: If the walls are too smooth, the room is prone to echoes, which increases the volume of noise.

Therefore, you can choose decorative materials with better sound-absorbing effect such as wallpaper, and you can also use decoration materials such as cultural stones to make the surface of the wall rougher, which can reduce noise. In addition, walls and ceilings can be made of soundproof materials, such as mineral wool sound-absorbing panels.

2.Fabric multi-purpose: The use of fabric to eliminate noise is also a more common and effective method.

The test shows that the sound absorption effect and effect of hanging and tiled fabrics are the same, such as curtains, carpets, etc., and the sound insulation effect of curtains is the most obvious. In addition, the carpet is laid to the soft touch, which not only produces a comfortable and warm feeling, but also eliminates the sound of footsteps, which is conducive to rest. In the bedroom, in order to ensure a peaceful resting environment, thick curtains and curtains should be used to control light and external noise.

3.Soft point of flooring: the fiber of wooden furniture, porous, can absorb noise, can be properly considered when purchasing furniture, and the use of cork flooring in decoration is also an effective choice.

4.The walls are thicker: the side facing the street should be soundproofed.

The windows on the street side are converted into "soundproof windows", such as double-layer windows, which can be effectively soundproofed, and insulating glass is used, and the sound insulation effect is also better. In addition, during the renovation period, you can add a layer of gypsum board to the wall facing the street, fill the wall with sound-absorbing cotton between the wall and the gypsum board, and then paste wallpaper or paint the wall paint on the gypsum board.

5.Soft lighting: Dazzling floors, ceilings, and walls can interfere with the central nervous system, distracting people, and make people extra sensitive to noise. Therefore, when decorating the interior, special attention should be paid to the soft light in the selection of various lamps and decorative materials.

When there is a particularly loud noise, open your mouth.

The best thing to do is to stay away. If you can't stay away, you have to add soundproofing materials, such as double glazing.
