Long term low dose noise can also cause chronic ear damage, how much do you know about the dangers o

Spending more than 8 hours a day in a sound environment above 85 decibels may lead to chronic hearing loss. The noise of everyday household appliances can also cause damage to the inner ear, etc.

The age of chronic ear injury is getting younger and younger, and it used to be more common in middle-aged and elderly people, but now it is frequently occurring in young people in their teens and twenties. Long-term exposure to a sound environment above 85 decibels can easily lead to hearing damage in the ear.

The noise environment has been ignored by us, the original environment in which people live is relatively quiet, but with the development of urban and rural transportation and industry, all kinds of noise have begun to appear around us, especially living in the city, many residences are in the downtown area, the roar of cars, noisy shouting, and the vibration of machines have broken into our lives, so that we have lost the quiet rest space. Noise, along with water pollution and air pollution, has become one of the three major sources of pollution that endangers the social environment.

Long-term exposure to noise can cause dizziness, nervousness, palpitation, tremors in the hands and feet, and even cause a variety of diseases such as high blood pressure, neurasthenia, and heart disease. Children and pregnant women are more likely to suffer from hearing damage not only to infants and young children, but also to the normal development of intelligence.

Noise can be said to be pervasive all around us, and the increase in motor vehicles has become the main noise**. Compared with the noise caused by construction sites and vehicles, the noise in life is easy to ignore, such as the noise from the TV in the home, the sound of the computer, the noise of the washing machine, etc., these sounds are generally between 50-70 decibels, and the noise of the refrigerator is between 34-45 decibels. Although these sounds are not loud, prolonged exposure to this low-dose noise can also cause damage to the ears.

The World Health Organization has shown that if the indoor noise exceeds 30 decibels, it will interfere with the normal sleep of the human body, and if the environment is above 70 decibels for a long time, hearing and physical health will be damaged to varying degrees.

I don't know much about it, but I only know that high-frequency noise can damage hearing, and I don't know that low-dose noise can cause damage.

I think noise will make me upset and irritable in the first place, because I like to be quiet, and after a long time, it will make me mentally bad, sleep badly, and get up to work the next day without any energy at all.

Noise can cause headaches, brain bloating, tinnitus, insomnia, general weakness, and neurosis. Causes indigestion, loss of appetite, nausea and vomiting, leads to gastrointestinal problems and ulcers. Causes rapid heartbeat, irregular heartbeat, increased blood pressure, arteriosclerosis, coronary heart disease.

Organs of vision: eyes, vision loss, dazzleness, reduced labor productivity.

Noise can cause deafness, hearing loss, tinnitus. It can also cause mental anxiety. It can cause chest tightness and shortness of breath, loss of appetite, memory loss, and can also affect endocrine disorders.

Damage to the auditory system can also affect mood and psychology, resulting in irritability, irritability, anxiety, and other negative emotions.

60 dB Around 70 dB: It will affect the normal sleep and rest of humans. 70 dB 100 dB:

It can make people upset, lose concentration and even affect the work effect, and accidents will occur. Above 120 decibels: extremely uncomfortable, severe can lead to total deafness.

If people are exposed to high-noise environments for a long time, it will cause cardiovascular and cerebrovascular diseases: the incidence of hypertension, arteriosclerosis and coronary heart disease is 2-3 times higher than that of ordinary people.

Long-term exposure to noise above 80db can easily cause noise-induced permanent hearing loss.

More than 110db (exposure to noise for more than 30 minutes, hearing loss) Rock** will (close distance).

Noisy stadium.

Jet landing.

Thundering ambulance horns.

Balloon sound** (closer to the ear).

The sound of firecrackers. Airbag.

85 110 dB (exposure to noise for about 6-8 hours, hearing loss) congested traffic.

Noisy bar.

Floor-to-ceiling air conditioning (close range).

Hair dryer motorcycle.

Squeeze the sounding toy (close to the ear).

Subway cars (passing through).

Long-term low-dose noise can also cause chronic ear damage.

There are many similar ones in lifeThe noise of the water pump, the noise of the transformer, the noise of the elevator, the noise of the computer case, the noise of the car horn, etc.

Every time the water is used, the noise of the pump <>

There is a lot of noise around us, the noise in the buildings, the noise on the road, the noise in the square, the noise in the market, and so on.

Let me tell you that we use tap water every time we have a house, and when we turn on the faucet, there is a noise, a noise from the pump pipes, and so on.

The production of these noises can lead to hearing loss in our ears.

In daily life, we should try to arrange our own life, install some soundproof devices, and try to reduce noise.

The noise of the elevator <>

People live in high-rise buildings, and the elevator is a tool that must be taken, and every time the elevator runs up and down, we will hear this sound.

This is a kind of noise that exists in life, and sometimes we find it annoying, but this is life, and it cannot be avoided.

In this case, the developer should take into account the problem of noise, install some noise-proof panels, soundproof panels, etc., and we should also take these things into account when decorating our own homes.

The noise of the computer case <>

The computer case at my home is a bit loud, and the generation of this noise also has an impact on hearing, and I work on the computer every day, and the damage to my ears is also very serious.

I don't think my hearing is very quick now, and sometimes I can't hear people talking to me, which is because I work long hours every day and often face these noises.

Health is our own, and in life we should pay attention and try to stay away from these noises.

Experts suggest that if you are exposed to these noises for more than 8 hours a day, it can lead to chronic ear damage over time.

Wearing headphones often will form some noiseMany young people like to wear headphones to listen**, or chase dramas, so that after a long time, it will damage the ear hearing, because the noise reduction of the headphones themselves is not particularly good, so it will have some impact on us.

In our daily life, we should try to reduce the opportunity to wear headphones, and protect our facial features is to protect our healthWhen you reach a certain age, it is very embarrassing to have problems in any part of your body.

This kind of is little by little, if you notice that your hearing is not good, it has reached an irreversible stage, like the sound of the walkman or the noise of daily household appliances at home for too long, there is also a certain damage to the inner ear, according to China's noise-related standards, more than 8 hours a day in the sound environment of more than 85 decibels and above, may cause chronic hearing damage.

With the rapid increase of urban and rural industry and transportation and population, all kinds of noise fill the environment around us, especially in the city, due to site limitations, many residential buildings are built in downtown areas or near factories. The cacophony of people, the roar of cars and the vibration of machines mercilessly invaded our living rooms, depriving us of our former peaceful resting environment. Noise has become one of the public hazards that pollute the human social environment.

The vibration of the drum beat in the dance hall can penetrate the wall and go directly to the living room and bedroom of the citizensElevators, transformer rooms and water pumps that were originally placed outside the building have been moved into the residential building (this method of using high-pressure water pumps to supply water will produce strong vibration and low-frequency noise, especially for residents below the fourth floor), and the vibration generated during use will form low-frequency noise.

There are four main types of low-frequency noise sources: elevators, transformers, and air conditioners, which generally refer to sounds with frequencies below 500 Hz (octave range). The direct impact of low-frequency noise on physiology is not as obvious as that of high-frequency noise, but domestic experts engaged in low-frequency noise research point out that low-frequency noise can cause headaches, insomnia and other neuroses.

Hello, noise-induced hearing loss will slow down with the duration of exposure to noise. Noise-induced hearing loss can be manifested as auditory fatigue in the early stage, which refers to the temporary hearing threshold shift of 10-30db after exposure to strong noise for a period of time, and hearing becomes dull, but this situation does not last long, as long as you leave the noisy place to stay in a quiet place for a period of time, the hearing will gradually return to its original state, this phenomenon is called temporary auditory threshold displacement, also called auditory fatigue.

Prolonged exposure to 60 dB noise will cause permanent hearing damage. （）
