Excessive sound can damage our hearing, and what should we do to protect it?

Protecting your hearing starts with reducing noise pollution. If you spend more than a certain amount of time in a noisy environment, you will definitely have hearing damage, so it is better to avoid these noisy environments! There are more and more young people listening to headphones on the road, in such a noisy environment, if you want to hear the sound in the headphones, the intensity must be very large, then the damage to the ears is certain, so usually try to use less headphones to listen **, even if you use headphones, it is recommended to use them in a quiet environment!

We usually use decibels to describe the volume of sound, and any sound that lasts for 8 hours or more and exceeds 85 decibels is considered unsafe. Such unsafe sounds abound in our lives, and these sounds will increase our risk of permanent hearing loss: for example, the sound of firecrackers has reached 125 decibels, **will, lawn mowers, some power tools, some loud motor vehicles, target shooting, fireworks, etc.

A few simple tips can help you determine if the noise around you is harming your hearing. For example, if you are in a noisy environment, an arm's length away from others, and you always have to raise the volume of your speech to drown out the noise to hear clearly, it is already a dangerous sign that the noise in this environment is already quite dangerous. In addition to this, there are other warning signs that warn you to be careful of these noises:

Away from this noisy environment, you will feel pain in your ears; Immediately after exposure to these noises, you will hear a "ringing" or "buzzing" tinnitus in your ears; After being exposed to these noises, you suddenly feel that it is difficult to understand what others are saying, and you can hear what others are saying but do not understand. If we want to listen easily and live happily, we need to avoid hearing damage and stay away from noise in our daily life.

Yes, noise not only affects our hearing, but also affects the development of the nervous system, memory loss, impairment of auditory vision, leading to endocrine disorders, increased incidence of cardiovascular diseases, difficulty concentrating, irritability and irritability, etc. The harm to human noise is limited to the superficial stage of not being able to sleep and affecting physical health, and it is extremely incorrect to pay no attention to noise.

1. Effects on fetuses and children.

Noise can cause a nervous reaction in the mother, causing uterine vasoconstriction, which affects the supply of nutrients and oxygen necessary for fetal development. Noise also affects the weight of the fetus. In addition, because children are not yet mature, the tissues and organs are very delicate and brittle, whether it is a fetus in the body or a newborn baby, noise can damage the auditory organs, so that the hearing force is reduced or lost.

Noise can also affect the mental development of children and adolescents, with surveys showing that children in noisy environments have 20% lower mental development than in quiet environments.

2. Impact on people.

Being in a noisy environment can cause annoyance, agitation, irritability, and even loss of mind. Noise is also tiring and therefore tends to interfere with concentration and productivity. It has a particularly strong impact on people who study and work at home.

It affects people's sleep quality, strong noise even makes people unable to sleep, upset or makes people dream and wake up, while the elderly and patients are more sensitive to noise interference.

Yes, long-term exposure to high-intensity noise can cause hearing damage. This damage is called noise-induced hearing loss, and it can be temporary or permanent. Temporary Keb hearing loss may recover within hours or days of exposure to noise, but it can lead to permanent hearing loss if exposed to high-intensity noise frequently.

Therefore, we should try to avoid prolonged exposure to high noise or take steps to reduce the effects of noise, such as wearing earplugs or earmuffs.

Being in a noisy environment for a long time is harmful to hearing. Prolonged noise can cause hallucinations to a person's hearing and is harmful to hearing.

If you don't pay attention, your hearing will be impaired, but also on your own emotions. Sleep quality and so on can be impaired.

Reduce the time you spend listening to songs with headphones, choose the right volume, and don't stay in noisy places such as KTV, bars, etc. for a long time.

Effective engineering controls are taken to reduce noise intensity. This is the most positive and fundamental approach. Install sound insulation covers for strong noise units, carry out sound absorption treatment in the workplace, and assemble mufflers on sound sources or sound paths.

Use ear protectors. Commonly used ear protectors are earplugs, earmuffs, and soundproof caps. The ear cups are the best in terms of sound reduction efficiency and wearing comfort, but they are large and inconvenient to carry.

Equipped with different ear protectors to protect hearing according to different places.

It can reduce the place where the noise of human voice and industrial noise is mixed.

Usually we should listen to songs or watch TV, we should experience it at a low volume, so that we can protect our ears and not listen to songs for too long.

Be sure to reduce the amount of time you spend wearing your headphones, and never turn them up too high, and don't go to noisy public places.

Generally, the maximum volume of *** is around 110 decibels.

The sound is below 40 decibels, which has no effect on the human body; When the sound is between 40 and 60 decibels, the nervous system will be affected if the human body is in this environment for a long time. At this time, the noise energy will double when the noise is increased by every 3 decibels; When the sound reaches 65 to 80 decibels, the degree of cardiovascular damage is more than 20 percent higher than that of people living in an environment with noise at 50 decibels. When the noise exceeds 80 decibels, it can cause great damage to people's hearing.

When the noise exceeds 100 decibels, it is unbearable noise. The sound reaches more than 120 decibels, which is equivalent to a Boeing 747 aircraft flying by the ear socks around it, and human health will be greatly harmed in a short time.

The normal hearing of people is 16-20000hz, too much noise will make the ears resist, and the tolerance is getting higher and higher, that is, the hearing is declining more and more
