What are the hazards of noise to the human body, and what are the hazards of noise 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.

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.
