The harm of noise to the body, the harm of noise to the human body?

1. Noise-induced hearing damage.

Noise tends to injure the hair cells in the ear, and once the hair cells are damaged, they will never recover. Generally speaking, high frequencies are more likely to cause hearing loss, so the average person's hearing high frequency has declined, but there is no process of detecting hearing, until the hearing is lost to the point that it is impossible to communicate with people.

2. Noise causes damage to the heart and blood vessels.

Acute noise exposure often causes hypertension, with increased adrenal hormone secretion and sympathetic nerve stimulation at 100 dB for 10 minutes. The same findings have been made in animal experiments. Although epidemiological findings are inconsistent, several recent large-scale studies have shown a positive association between long-term noise exposure and hypertension.

Exposure to noise from 70 dB to 90 dB for five years is up to a fold risk of getting high blood pressure.

3. The effect of noise on reproductive ability.

In recent years, some experts have put forward the theory of "environmental hormones", pointing out that there are chemicals in the environment that can affect the body's endocrine function like hormones, and noise is one of them. It can cause endocrine disorders in the human body, and long-term noise pollution can cause male infertility; In women, it can lead to miscarriage and fetal malformations. Research in other areas is still inconclusive and needs to be further sent**.

4. The effect of noise on sleep.

Up to 28% of people believe that noise affects sleep, noise can lead to neurasthenia, in the noise environment, most people can not fully enter deep sleep, the relevant regulations clearly point out that the day should not exceed 50 decibels, the night should be less than 45 decibels, if this standard is exceeded, it will cause harm to the human body.

5. The impact of noise on psychology.

Under the high frequency of noise, most people have symptoms of restlessness and are easily agitated. Some studies have found that the quieter the workplace, the more accidents there are.

The harm of noise to the human body is multifaceted, and long-term work or life under high decibel noise will produce the following results: First.

1. Noise-induced deafness, mainly manifested by hearing loss, tinnitus, and in severe cases, complete hearing loss may occur, often caused by noise pollution in the working environment.

Clause. 2. Mental anxiety, people who live in noise for a long time are prone to anxiety, showing irritability, restlessness. In severe cases, patients may have somatization symptoms such as palpitation, chest tightness, shortness of breath, fatigue, loss of appetite, memory loss, and low work efficiency.

Clause. 3. Autonomic nerve and endocrine dysfunction, mainly manifested as palpitation, chest tightness, sweating, insomnia, dreaminess, early awakening, dizziness, headache, easy fatigue, irregular menstruation, acne, etc.

Clause. 4. People who live in noise for a long time may experience an increase in blood pressure. Hope.

Hazards of noise: 1 Damage to the auditory organs, manifested as noise-based hearing damage, can cause tinnitus and hearing loss. 3. Damage to the nervous system can cause blindness, neurasthenia cause headache and dizziness.

If you are in a state of noise for a long time, you will have insomnia. 3. Damage to the cardiovascular system can cause changes in heart rate, which can cause an increase in blood pressure. 4. Damage to the digestive system can also cause poor appetite and loss of appetite.

5 Damage to the endocrine system can cause endocrine disorders, and then cause some discomfort in the body.

The damage of noise to the body includes:

1. Cause hearing loss.

Long-term exposure to excessive noise will seriously affect people's hearing, and in severe cases, it will also cause deafness.

2. Cause cardiovascular and cerebrovascular diseases.

Especially for the elderly, the nerves are sensitive and respond to noise, and long-term noise will make people mentally anxious and nervous fragile.

3. Cause mental problems, affect people's emotions, and decline memory.

Noise can cause mental irritability, and noise at night can also make people sleep deprived, which can make people lose energy, lead to emotional problems, which can lead to memory loss.

Noise can cause a variety of hazards to the human body, such as causing sleep disorders, hearing disorders, mental disorders, etc., usually the longer the exposure to the noise environment, the higher the noise decibels, the greater the harm to the human body. According to the noise standards set by the WHO, the ideal noise level should be around 35-40db at rest or in a ward environment.

1. Sleep disorder: Usually when the noise is 50-60db, it will make people feel noisy, which can affect rest and sleep, making it difficult for people to fall asleep or wake up in sleep. For people who need to rest, especially for patients with various diseases, it has a great impact, which can easily lead to fatigue, fatigue and drowsiness;

2. Hearing impairment: long-term exposure to noise above 90db can cause tinnitus, and for sudden noise, such as ** sound, when its intensity is as high as 120db or more, it can cause hearing loss or permanent deafness;

3. Mental disorders: long-term exposure to noise above 90db can also make people anxious, irritable, and even develop into mental illnesses such as anxiety disorders. For patients with various mental disorders, often being in a noisy environment is extremely unfavorable to recovery, and noise may become a predisposing factor for anxiety and depression, and even lead to aggravation of the disease;

4. Other hazards: long-term exposure to noise environment can cause dizziness, headache and other nervous system discomfort symptoms, in addition, noise can also cause the human body's stress response, resulting in gastrointestinal system dysfunction and increased adrenal gland secretion, causing vasoconstriction, blood pressure increase, may cause transient blood pressure rise, and even develop into hypertension, which can cause obvious harm to the human body.

Noise is a sound that people don't want. It often affects people's mood and health, interfering with people's work, study and normal life. There are three categories of productive noise: mechanical, aerodynamic and electromagnetic.

Mechanical noise includes ball mill noise, shearing machine noise, locomotive noise and spinning machine noise.

Aerodynamic noise includes fan noise, gas turbine noise, exhaust boiler venting noise, etc.

Electromagnetic noise includes generator noise, transformer noise, etc.

Long-term work in a noisy environment without taking any effective protective measures will inevitably lead to permanent and irreversible hearing loss, and even severe occupational deafness. Occupational deafness has been listed as one of the important occupational diseases at home and abroad. In addition to causing deafness, strong noise can also have adverse effects on the nervous system, cardiovascular system, digestive system, and reproductive function.

Particularly strong noises can also lead to nervous disorders, shock, and even life-threatening. Because noise is easy to cause psychological fear and obscuration of alarm signals, it is often an important cooperating factor that causes work-related fatalities.

Workers with occupational deafness find it difficult to communicate with others at work, which affects work efficiency; in daily life and social activities. I can't communicate my thoughts and feelings with my relatives or friends well, and I can't appreciate the wonderful ** and opera. Especially in later years, this situation is more serious and can cause great suffering.

Hope it helps you and please thank you in time.

The harm of noise to the human body is that it can cause people to have a certain amount of anxiety, and it will lead to neurasthenia, affect the state of sleep, and even have a certain impact on the heart.

Noise is a type of sound that causes irritability or is too loud and harmful to human health. Noise can be physically and psychologically harmful: if people work in a loud noise environment for a long time, it will damage the hearing tissue of the inner ear, and in severe cases, it will cause deafness.

It can affect people's hearing, excessive noise may even cause temporary deafness, long-term work under noise will cause hearing loss, affect mood, make mood impetuous, irritable, distracted, cause accidents, so noise is counted as a kind of occupational disease hazard, is an examination item during physical examination.

When the noise reaches 30 decibels, it will affect the patient's sleep, and if it reaches 70 decibels, the person's body and health will be affected. For example, tinnitus, and hearing loss.

The hazards of noise to the human body are:

Gravitational hearing loss can make a person irritable, increase blood pressure and increase heart rate.
