How can noise hazards be avoided? Noise hazards and prevention ?

Soundproof space. When you can't stop the noise**, a soundproofed home will help you rest more easily at night and keep your home quiet during the day. If you don't want to rebuild your walls and soundproof flooring, consider installing carpets and wall coverings to soften and absorb sound as a less expensive option.

Keep noisy machines away from your bedroom and living area. If there are any other** constant noises, try to find them away from your sleeping and living areas so you can have some peace and quiet. You may also want to consider using these machines without giving yourself a break from the noise.

For example, turn off the air conditioner and open the windows, even if it means a little hotter than normal. You may find the less noisy atmosphere more relaxed than the cooling room.

Take time away from the noise. Sometimes it's just not possible to really stay away from the noise. If you live on a busy street, there will be sirens and car horns.

Getting away from it all is a great way to restore your emotional balance. Go to a quiet place and enjoy a few hours of silence until you feel restored and ready to enter the noise of everyday life. See if you can walk away from the busy roads in a quiet natural spot.

If you can't get it to go to a quiet outdoor space, try sitting in the library for a few hours. The librarian will make sure it is quiet.

Learn to meditate. As more and more rural areas develop, the noisy engines and building sounds aren't going away anytime soon. Learning how to meditate can help you deal with noise and stress without having to let go of everything and leave.

When you feel overwhelmed, sit quietly, close your eyes, and focus on taking a deep breath, even breathing. Take 10 breaths and try to let your worries go and ignore the noise around you. It doesn't matter if you're in **, whether it's on the noisy subway, or in your own kitchen, you can try this method to calm yourself down.

Use earbuds and headphones. These inventions help people deal with millions of noises every day. Earplugs are an inexpensive drugstore purchase that buys you sleep for the duration of your sleep once you get used to falling asleep when they are in your ears.

Noise-cancelling headphones are a bit pricey, but they might be worth your money if you make silence and quiet your priority.

Among the various factors that can cause harm to the human body, noise is one of the more harmful ones.

Noise damage can bring the following hazards to the human body:

1. Noise can damage people's hearing. Causes hearing loss and even hearing loss.

2. Noise can seriously affect people's emotions and thinking, disturb the mind, and bring great damage to people.

To avoid noise hazards, the following measures can be taken:

1. Wear earplugs to isolate noise.

2. Keep away from noise sources.

3. Take measures to eliminate noise sources.

There are 3 ways to reduce noise: one is to reduce noise at the sound source; the second is to reduce the noise in the process of sound propagation; The third is to reduce noise at the human ear.

1) To reduce the noise of the sound source, the industry and transportation industry can choose low-noise production equipment and improve the production process, or change the movement mode of the noise source (such as damping, vibration isolation and other measures to reduce the vibration of the solid sound emitter).

2) Reduce noise in the sound transmission pathway, control the propagation of noise, change the noise propagation path that has been emitted by the sound source, such as the use of sound absorption, sound insulation, sound barrier, vibration isolation and other measures, as well as reasonable planning of urban and building layout.

3) When measures cannot be taken in the sound source and transmission path, or the acoustic measures taken still cannot achieve the expected effect, it is necessary to take protective measures for the sound recipient or the sound receptor, such as workers with long-term occupational noise exposure can wear earplugs, earmuffs or helmets and other ear protectors.

When using personal audio devices normally, keep the volume below 80 decibels. As a rule of thumb, it's usually at 60% of the phone's maximum volume. In noisy environments, hearing can be protected by using earbuds, using the right earbuds can reduce sound exposure by 5 to 45 decibels, controlling the time of sound exposure, limiting the time personal audio devices are listening, taking regular breaks, and staying away from loud environments.

The Law of the People's Republic of China on the Prevention and Control of Environmental Noise Pollution is formulated to prevent and control environmental noise pollution, protect and improve the living environment, protect human health, and promote economic and social development. It was adopted at the 22nd Session of the Standing Committee of the Eighth National People's Congress on October 29, 1996, and came into force on March 1, 1997.

Be careful not to stay too long in front of loud speakers or in KTV, do not listen to headphones for a long time**, and adjust the volume slightly smaller. When setting off fireworks and firecrackers, be a little farther away from the setting point to avoid the huge sound shock to the ears and affect the hearing.

How can noise hazards be avoided? I think you can actively stay away from the source of the noise! Of course, you can also install acoustic panels or buy noise-cancelling headphones at home.

To avoid noise hazards, the first thing to look at is the geographical location of the place where you live.

Noise hazards are: easy to make people restless, insomnia, emotional loss, headache, easy to cause farm production reduction, etc. Measures to effectively avoid noise pollution: first, increase noise pollution control; The second is to shut down or evacuate noisy enterprises away from residential areas.

Noise hazards:

1. The impact of noise on the auditory system, noise will damage the noise of hair cells in the cochlea, resulting in the death of hair cells, resulting in hearing loss. This hearing loss is called hearing loss nervosa and is also permanent.

2. The impact of noise on the nervous system can lead to tinnitus, lack of concentration, memory loss, emotional instability, etc.

3. The impact of noise on the cardiovascular system, such as rapid or slowed heartbeat, irregular heart rate, increased blood pressure, etc. 4. The impact of noise on the digestive system, such as indigestion, loss of appetite, nausea, and increased incidence of stomach problems 5. Noise will also have adverse effects on the reproductive system and other systems.

Noise control:

Prevention and control are generally considered from the following aspects: engineering measures, management measures and personal protection.

Engineering measures include: 1. Elimination, which is the most difficult to do, that is, to eliminate the noise source, which is generally the noise emitted by mechanical equipment, and it is very difficult to remove the equipment. 2. Replacement, that is, using lower noise equipment to improve high noise equipment, the cost is not low.

3. Collective protection, that is, to install a protective cover for the equipment, so that the noise of the equipment will not be transmitted, or to build a special studio for employees so that the noise can not enter.

Noise is mainly harmful to health, to effectively prevent it, it is necessary to prevent the sound source of the noise from the way of transmission and the process of reaching the human ear.

Hello! Long-term exposure to noise and lack of protection can lead to hearing loss, and in severe cases, it can cause noise-induced deafness.

Reasonable planning and design layout of the plant, the distance between the workshop and the non-noisy workshop that produces strong noise.

The harm of noise mainly affects our eyesight, not quiet, may also affect people's rest, want to prevent noise, but also look at the source of noise? Or how does the noise come about? Then choose the treatment method according to the specific noise situation.

After a long time, it will definitely kill and injure people's hearing, cause harm to people, work in noisy places, or stay away. Protective tools, such as earplugs.

Since the 50s of the 20th century, with the development of modern industry and transportation, the problem of noise pollution has become increasingly serious, and it has become the four major environmental pollutants recognized worldwide.

Go to the hospital for a check-up, don't think it's a trivial matter, don't be afraid of 10,000.

Noise has varying degrees of effects on the nervous system, cardiovascular system, endocrine system, digestive system, immune system, cerebral blood flow and reproductive system.

When people enter a noisy environment and are exposed to it for a period of time, they will feel uncomfortable in both ears and even have headaches. Leave the noisy environment and rest in a quiet place for a while, and your hearing will gradually return to normal. This phenomenon is called temporary hearing threshold shift, also known as auditory fatigue.

However, if people work in a loud noise environment for a long time, auditory fatigue cannot be recovered in time, and organic lesions will occur in the inner ear organs, that is, permanent hearing threshold shift, also known as noise deafness.

If a person is suddenly exposed to extremely strong noise, the auditory organ will be traumatized sharply, causing tympanic membrane rupture and bleeding, labyrinthine bleeding, and acute detachment of the spiral apparatus from the basement membrane, which may cause the human ear to completely lose hearing, that is, detonation deafness. Studies have shown that noise pollution is an important cause of presbycusis. In addition, hearing loss is also related to the environment in which they live and the occupation they are engaged in, for example, the incidence of presbycusis is lower in rural areas than in urban areas, and textile factory workers, blacksmiths and blacksmiths have more hearing loss than their peers.

Noise can induce a variety of diseases** because noise acts on the central nervous system of the brain through the auditory organs, so as to affect all organs of the body, so noise not only causes damage to human hearing, but also brings harm to other systems of the human body. As a result of noise, neurasthenia such as headaches, brain swelling, tinnitus, insomnia, general fatigue and weakness and memory loss can occur. People who work in high-noise environments for a long time have 2 to 3 times higher incidence of hypertension, arteriosclerosis and coronary heart disease than those who work in low-noise environments.

Visible noise can cause diseases of the cardiovascular system. Noise can also lead to digestive system dysfunction, causing indigestion, loss of appetite, nausea and vomiting, and increasing the incidence of gastrointestinal diseases and ulcers.

It is easy to cause mood, very bad, easy to lead to anxiety, depression also brings damage to the organs of the body, easy to lead to indigestion, easy to lead to the destruction of the immune system, we must pay attention to quiet in life, and the choice of doors and windows is best to choose sound insulation.

Noise can affect people's nervous system, so that people's hearing is affected, a variety of trees, greening can reduce noise, smooth road surface can also reduce noise, buildings can increase more sound insulation layer.

It will affect the atmospheric environment, not affect the quality of life, but also affect people's hearing and vision; Keep away from noisy places, don't make any noise, and wear earplugs when you sleep.

Noise pollution refers to the phenomenon of noise in the environment exceeding the normal level, which has an adverse impact on human health and social production and life. In order to avoid noise pollution, you can start from the following aspects:

1. Pay attention to the sound sources around you. Be aware of the noise sources around you and try to avoid living or working in noisy areas, such as near highways or airports.

2. Control the noise of production, construction and equipment. In industrial and construction sites, low-noise equipment and materials should be used, and equipment should be regularly inspected and maintained to avoid noise pollution.

3. Use soundproofing materials and equipment. Install noise-proof equipment such as soundproof doors, windows, walls, and screens to reduce the spread and spread of noise. These devices can effectively separate the noise between the external environment and the indoor living or office space.

4. Actively reduce personal noise pollution. Everyone should be as quiet as possible, try to avoid making noise in public places, and don't turn the volume up too high to avoid noise pollution to others.

5. Cultivate good living habits. It is necessary to minimize noise-related living habits, such as watching less TV, listening less, using vacuum cleaners, etc., and should establish a green, low-carbon and environmentally friendly life concept, choose low-noise household appliances and transportation, and reduce noise pollution.

The above measures can not only avoid noise pollution, but also help to improve physical and mental health, protect people's production and living environment, and improve the quality of life.
