How to Prevent Noise Induced Deafness in Adolescents?

Prevention starts with the baby, but adults should also develop awareness of the prevention of tinnitus and deafness. Since the 80s of the 20th century, the number of adolescent noise ear loss has been increasing, making adolescent noise ear loss the focus of ear scientific research at home and abroad. When adolescents are exposed to high-intensity recreational noise for a long time, it may lead to harmful symptoms such as hyperacusis or tinnitus, and they comprehensively evaluate the harm of noise, the possibility of harm to the human body, and the benefits obtained from it (such as pleasure, participation in activities to expand interpersonal communication, etc.).

If you feel that the advantages outweigh the disadvantages, and at the same time have the persuasion of family and friends, you will have the behavior of protecting your hearing, get rid of the high-intensity noise environment, so as to reduce the damage to your hearing, and form a virtuous cycle; Otherwise, a vicious circle is formed. The intensity and duration of noise exposure are independent risk factors, and it is recommended that adolescents should not last more than an hour when using the **** device, and the intensity of the sound should not exceed 60% of the maximum output intensity. Prevention of noise-induced ear loss in adolescents is achieved by reducing the intensity of noise exposure, reducing the duration of noise exposure, or advising adolescents to minimize or minimize exposure to noise.

Adolescent noise loss is mainly caused by recreational noise exposure, and there is no effective drug to protect the hearing health of adolescents.

That is to avoid exposure to noise.

1. Ear sound insulation, with earplugs, earmuffs, soundproof caps and other soundproof equipment, generally in the noise environment of 80 decibels, long-term work should be equipped with simple earplugs, more than 90 decibels, protective tools must be used.

2. It is the most fundamental way to control noise, which is the most fundamental way to prevent noise-induced deafness, and various sound insulation, shockproof, and sound-absorbing measures should be used to reduce noise when installing machines in construction plants.

3. Health monitoring: Hearing should be checked before employment, and those with sensorineural deafness and noise sensitivity should avoid working in a strong noise environment. For those who are exposed to noise, their hearing should be checked regularly to detect early hearing damage in time and treat it properly.

4. Reduce contact time: such as taking a break between work in a soundproof room, or reducing the daily and weekly exposure time to noise, it can also reduce the morbidity. It can also rotate the type of work according to the actual situation, which can also reduce the hearing damage.

Since it is noise-induced deafness, if you want to prevent it, you must stop the damage caused by noise, which is nothing more than two ways.

First, get away from the noisy environment, that is, find a quiet place to work and live. This is the most effective and straightforward method.

Second, isolate noise pollution, decorate the room with soundproofing materials, or use earplugs and sound-isolating headphones to protect your ears.

First of all, it is necessary to strengthen the publicity and education of noise-related deafness, focusing on people who are exposed to noise. Because noise deafness only occurs in people who are exposed to noise, such as firecrackers on holidays, textile factory workers, operators wearing headphones, artillerymen, ship engineers, tank pilots, airfield personnel, and people who often wear headphones to listen to the Walkman**, and practice karaoke singing rooms and disco halls for a long time, and the degree of noise deafness hearing loss is closely related to the noise intensity and the time of exposure to noise, most of the noise deafness is caused by the accumulation of noise damage during the long leakage comic period, and the early symptoms are not obvious. It often does not attract people's attention, and when it is serious to a certain extent and there is no effective **, it is too late to regret it, so it is important for them to raise their awareness of noise deafness and enhance their awareness of noise prevention.

Second, effective control of environmental noise is fundamental to the prevention of noise-induced deafness. In order to control ambient noise, strict noise hygiene standards have been established. The Law of the People's Republic of China on the Prevention and Control of Environmental Noise Pollution was adopted and promulgated at the 20th Session of the Standing Committee of the Eighth National People's Congress of the People's Republic of China on October 29, 1996, and came into force on March 1, 1997.

Provisions: The allowable noise standard for 8-hour work-return sales is 85db (a), which can be appropriately relaxed if it cannot be reached temporarily, but shall not exceed 90db (a). The noise exposure time is less than 8 hours, i.e. the contact time is halved, and the noise can be increased by 3dB, but not more than 115dB(a).

In order to meet the noise hygiene standards, reduce the noise to a safe limit (85 90db (a)), and enterprises must increase investment and take corresponding measures to improve the plant construction and improve the mechanical equipment and technical operation to effectively reduce noise, such as the installation of silencing, sound insulation, sound absorption and shockproof facilities in the noise tung sound workshop.

If you have a loud voice, then the chances of the AI dragon must be prevented.

Slow, progressive sensory deafness due to long-term exposure of hearing to noise (85-90db) is called noise-induced deafness.

Relevant data show that adolescents with long-term Walkman are one of the groups of people with noise-induced deafness. Or CD is 87 dB for normal earbuds. The United Nations stipulates that the maximum volume of any Walkman cannot exceed 100 dB.

Obviously, even the iPod (the world's largest **** production business) sound indicator is at 30

102 db) violated this regulation, and even more so other brands?

Experiment: An employee of a company was invited to test his voice sensitivity in the morning, and his hearing was normal. When the employee went to work and got off work (during the listening period), he often enjoyed karaoke for a while after work, and then tested it after returning home, his hearing still remained in the normal range, but the original 10 dB sound could not be heard until 20 dB.

Obviously, the sensitivity drops, which is a transient hearing loss, and the capillary cells in the cochlea take 16 hours to repair, and if the capillary cells are not given enough rest, it will be in the long run.

It is possible to go from temporary deafness to permanent deafness.

Most hearing loss builds up over time and can be difficult to detect. How can I know.

Has Dao's hearing been affected?

Here are some of the symptoms of hearing loss:

1.It is difficult to distinguish certain words or words, 2Constantly ask others to repeat what is said, 3

**Can't hear each other clearly during a call, 4The rest of the room thinks you're watching TV or listening to the radio room with the volume turned up too much, 5It is difficult to distinguish sounds in a noisy environment, and when listening to sounds, it feels like being covered.

Hearing loss due to the need for work or play in a noisy environment is actually 100% preventable.

Here are some common tips to reduce the harm your hearing can be exposed to:

1.limit residence time in noisy environments;

2.Always wear soundproof earplugs or other hearing protection when participating in activities with loud ambient sounds.

3.Be alert to the noise level of your surroundings.

4.Protect children from high-intensity noise because they don't yet know how to protect themselves.

5.Identify and assess hearing loss as early as possible**.

It's never too early or too late to start hearing protection.

People who work under noise for a long time are more likely to have noise-induced hearing loss.

In daily work and life, you should pay attention to avoid noisy environments as much as possible, do not stay for a long time, and use anti-noise earplugs to protect your hearing.

1.Control noise**.

2.Reduce noise exposure time.

3.Wear earplugs, earmuffs, soundproof caps and other soundproof equipment. Generally, simple earplugs should be used for long-term work in 80db noise environment, and protective tools must be used when above 90db.

If it is simple, you can use cotton to plug the external ear canal and then apply petroleum jelly, which has a sound insulation value of up to 30db.
