What are the hazards of working in a noisy environment?

Working in a noisy environment for a long time can affect your health. Over time, it can lead to hearing loss and even migraines, which can affect the mental state of the whole person.

Long-term noise can interfere with life and work, and damage hearing. 40 dB is normal ambient sound and is generally considered the hygienic standard for noise. Above this is harmful noise, noise of about 50 decibels can affect rest and sleep, and noise above 70 decibels can make people upset and lose concentration.

Affect the life of human beings, make people get diseases, noise pollution hazards, pregnant women are exposed to a noise environment of more than 50 decibels for a long time, which will cause endocrine gland dysfunction, and mental stress and endocrine system disorders. In severe cases, it will increase blood pressure, fetal hypoxia and ischemia, lead to fetal malformations and even miscarriage. The high decibel noise can damage the hearing organs of the fetus, causing some areas to be affected.

Affects the development of the brain, leading to mental retardation in children.

The human ear is more suitable for 60-70 decibels of sound, and 80-90 decibels will feel very noisy, and nerve cells will be destroyed; If the volume exceeds 100 decibels, it is enough to cause the death or damage of the hearing hair cells inside the ear, resulting in hearing loss.

Constant exposure to noise.

It can seriously affect people's hearing, and people refer to sound pressure levels that exceed the need and affect hearing as vocal violence. If the sound pressure level of the sound reinforcement system is too high, it will cause a waste of energy and a waste of sound reinforcement equipment resources. Some people say that an increase of 3 decibels is not a big deal, but they don't know that a 3 decibel increase in sound pressure level will double the power of the amplifier, and sometimes even double the equipment.

It comes at a great cost.

The overwhelming logarithm of sound is used as the unit of expression, that is, the sound pressure level is used to express the magnitude of the sound volume. Sound pressure level is measured in decibels:

10 20 decibels, the sound of falling leaves, almost imperceptible.

20 40 decibels is equivalent to speaking softly.

40 60 dB is equivalent to indoor conversation.

60 70 dB, business office, damage to nerves.

70 90 decibels, busy street sound, very noisy. Studying and living in this environment for a long time will gradually destroy people's nerve cells.

90 100 dB, pneumatic rig sound, can cause hearing damage.

100 120 decibels, the sound of the ceramic cutting machine, is unbearable, and can temporarily deafen in a few minutes.

Generally, when the sound is around 30 decibels, it will not affect normal life and rest. And when it reaches more than 50 decibels, people have a greater feeling and it is difficult to fall asleep. Generally, a sound of 80 decibels or more is considered noise.

The sound pressure level of the sound we hear in our daily life is around 0-140 decibels. The intensity of the noise is also expressed in terms of sound pressure level. The minimum sound level that a normal person's hearing can perceive is 1 decibels.

A soft whisper is about 30 decibels. The conversational language is about 60 decibels at a distance of about 1 meter. About 80 decibels in buses.

The noise in heavy-duty trucks, weaving workshops, and subways is about 100 decibels. 120 decibels for aircraft take-off, ball mills, electric cutters.

1.Noise can cause hearing damage; 2.Noise has an impact on reproductive capacity; 3.

Noise can easily cause damage to the heart and blood vessels; 4.Noise has an impact on a person's sleep quality; 5.Noise can make people restless.

Noise pollution is mainly used in transportation, vehicle horns, industrial noise, building construction, social noise such as halls, loudspeakers, morning markets and people's loud talking.

It can easily cause ear discomfort such as tinnitus, earache, and hearing loss. Especially in the noise at night, life can be boring, irritable, and irritable.

Harmful to the human cardiovascular system, China's survey of urban noise and residents' health shows that for every decibel increase in regional noise, the incidence of hypertension increases by 3%. It affects the nervous system of the person, making the person irritable and irritable. Interferes with sleep and causes tiredness.

If you are in a noisy environment for a long time, it is easy to cause tinnitus, which can seriously lead to hearing damage. It is also easy to lead to excessive anxiety and endocrine disorders. It may cause the child's attention to be distracted.

It affects the functioning of the brain and can also cause some effects on the ears. So it's still very harmful.

1. Noise damage to hearing organs: The direct harm of noise to the human body is hearing damage. According to statistics, there are more than 70 million deaf people in the world today, and a considerable part of them are caused by noise. Expert studies have proved that indoor noise in the home is the main cause of deafness and mute in children, and if you live in noise above 85 decibels, the deafness can reach 5%.

2 The influence of noise on conversation and communicationNoise hinders people's conversation and communication. Normally, the intensity of people's normal conversation is 60 70db, and the ambient noise of playing ** can be heard clearly at 60db, and the noise exceeds 70db and cannot be used**. 3 The impact of noise on human physiologyNoise has a serious impact on human physiology.

Under the action of strong noise, the balance between excitation and inhibition in the cerebral cortex is out of balance, resulting in conditioned reflexes, damage to cerebral vascular tone and changes in brain potentials, and in severe cases, it can cause exudative hemorrhage. The physiological changes caused by noise can be recovered in a short period of time (within 24 hours), but if they are not recovered in time, a firm excitatory foci will be formed, resulting in clinical symptoms such as headache, brain swelling, dreaminess, insomnia, palpitation, reduced neurobehavioral ability and general fatigue. Symptoms such as palpitations, irritability, and memory loss may also occur.

4 The impact of noise on people's psychology Noise makes people annoyed, easily fatigued, and irritable, which affects people's attention and work efficiency, especially for those complex operations that require a high degree of concentration. Studies have found that noise levels above 85 decibels can make people feel distracted, unable to concentrate on their work, and reduce work efficiency. Noise can also cause fatigue, and high-frequency noise is more likely to cause fatigue.

5 The impact of noise on people's normal lifeQuiet is an important environmental element for people's normal rest, sleep and social activities, but under the interference of various noises, the quiet environment is becoming less and less. The ideal sleep environment noise level is below 35dB, and when the noise exceeds 50dB, about 15% of people sleep normally are affected. Rest and sleep are necessary conditions for people to eliminate fatigue, restore physical strength and maintain health, but noise makes people nervous, shortness of breath, and over time, they will get neurasthenia, manifested as insomnia, tinnitus, and fatigue.

6 Noise can damage eyesightNoise can also affect vision. The test shows that when the noise intensity reaches 90 decibels, the sensitivity of human visual cells decreases, and the reaction time of recognition of weak light is prolonged, when the noise is 95 decibels, 40% of people's pupils are dilated and their vision is blurred, and when the noise reaches 115 decibels, most people's eyeballs have different degrees of adaptation to light brightness.

Therefore, people who have been in a noisy environment for a long time are prone to eye damage such as eye fatigue, eye pain, dizziness and tearing.
