Let s talk about the harm of noise after working for a long time?

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 deviation, 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, violent deafness. Not only hearing can cause damage to other systems. ‍‍

Prolonged exposure to high-intensity noise can have an impact on the human body's hearing, sleep, cardiovascular system, and mood. My friend works in this environment, and he said that long-term ambient noise can interfere with sleep, cause insomnia, memory loss, and seriously affect normal life.

Noise decibels in the workplace exceed a certain level, which can cause a certain degree of wear and tear on your ears.

It will cause some damage to your hearing. In this environment, it is best to wear protective earplugs.

If you work in noise for a long time, you may have tinnitus and your hearing will be affected, so try not to work in a noisy space for a long time.

Working in a noisy environment has a great impact on human hearing, causing permanent noise-induced hearing loss, which will never recover once the sensory cells are damaged.

If the noise works for a long time, it may cause some harm to people's ears. In severe cases, it can also cause deafness in the ear.

Working in a noisy environment for a long time will cause some damage to your hearing. In this environment, it is best to wear protective earplugs.

The risk of suffering from tinnitus increases, and working in this environment for a long time will cause pain in the head, which will make you feel very irritable, and this kind of work is still very bad.

Working in a noisy environment for a long time can damage the ears and cause tinnitus.

If you work in a noisy area for a long time, your eardrum will be damaged, and it may be the back of the ear

I don't know about others, I have been engaged in two noisy jobs, one is clothing sales all day and night, **** basically put back and forth on those few songs, lost nearly twenty pounds in half a year, a factory general worker in three shifts in the packaging department, the roar of the machine is really uncomfortable, more than three months, one hundred and fifty sixty pounds, thin to one hundred and sixteen, it is really a good job.

Yes. Hazards of working in a noisy environment for a long time:

1.Noise distracts people's attention, is easy to get tired, and responds slowly, which affects work efficiency and makes work errors.

2.Damage to the auditory organs.

There is a certain limit to the adaptability of human hearing organs, and long-term work under strong noise will cause auditory fatigue and hearing loss. If repeated effects of strong noise occur over many years, organic lesions will occur in the ear organs, resulting in noise-induced deafness.

3.Causes disorders of the cardiovascular system.

Noise can strain the sympathetic nerves, manifesting as a rapid heartbeat and irregular heartbeat.

Blood pressure fluctuations, ECG.

Increased positive tests.

4.Effects on the nervous system Noise causes neurasthenia.

Symptoms, such as headaches.

Dizziness, insomnia, dreaminess, memory loss, etc. The positive detection rate of neurasthenia increases with increasing noise intensity.

5.In addition, noise can cause gastric disorders and reduced vision.

6.When the noise exceeds the sound of the alarm signal of the production control system, the alarm sound signal is drowned out, which is easy to lead to accidents.

If you come to work for a long time, it will have a great impact on your body. Noise is an occupational disease. Over time, it will make you hearing impaired.

Working under noise for a long time must affect the body. Especially pregnant women. It's best to avoid noise. That's good for the body.

Long-term work under noise, without wearing protective measures, will have an impact on physical health, if the protective measures are appropriate, reasonable rest, no harm to the body.

If a person is in a noisy environment for a long time and works for a long time, it will definitely cause irreversible damage to his body. So we should avoid that.

Working under noise for a long time is easy to damage hearing and can also cause neurasthenia.

Working in a noisy working environment for a long time is actually the main impact on hearing, which will make your hearing fall into a state of decline.

If you work under noise for a long time, it may have an effect on your ears, and then if you are in a bad mood, you may be in a worse mood if you are in a bad mood for a long time, so you adjust yourself.

If the noise in the environment of your position is relatively loud, you should have a detailed examination and planning for some occupational diseases in the unit, well, if it has an impact on the body or hearing. It should be good for this environment.

At the very least, it has an impact on your ear hearing, that should be sure.

If I work in noise for a long time, will it affect my body? I must think that I have one item of my own, and if I look at my hearing when I look at work, I may not be buying it well.

It can cause noise-induced tinnitus or noise-induced deafness, which can cause the cochlea to be damaged by prolonged exposure to noise, damage to the base of the cochlea, and decreased function of cochlear hair cells, which in turn can cause neurological deafness and neurological tinnitus.

Noise is a type of sound that causes irritability or is too loud and harmful to human health. From the perspective of environmental protection, all sounds that hinder people's normal rest, study and work, as well as sounds that interfere with the sounds that people want to listen to, are classified as noise.

From a physical point of view, noise is the sound produced when the emitter vibrates irregularly.

Aerodynamic noise, turbulence, jet flow, cavitation, air cut, vortex and other phenomena generated by flow. When the air flows through the duct or metal surface at high speed, the general air flow in the catheter will encounter obstacles, resulting in turbulence or large and rapid pressure changes, and noise will be generated.

Noise pollution poses a hazard to people, animals, instruments and buildings, and its degree of harm mainly depends on the frequency, intensity and exposure time of noise. Noise hazards mainly include: noise damage to hearing, and the direct harm of noise to the human body is hearing damage.

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 loud noise...

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.
