What are the criteria for determining noise induced deafness?

Hello: What are the criteria for determining noise-induced deafness?

Several tests are required to make a decision. However, noise-induced deafness has the following hazards:

Noise-induced deafness is a slow and progressive sensorineural hearing loss due to the long-term influence of noise on hearing, which is manifested as auditory fatigue in the early stage, and can gradually recover after leaving the noisy environment, but it is difficult to recover over time, and eventually sensorineural hearing loss. In addition to hearing damage, noise can also cause headaches, dizziness, insomnia, high blood pressure, etc., affecting stomach peristalsis and secretion. Hope mine is helpful to you.

Have a clear history of noise exposure, i.e., a history of long-term overtime operation in environments above 85dB(A). Complaints of bilateral tinnitus and progressive deafness without other astringents.

Noise-induced hearing loss is hearing loss caused by long-term exposure to noise.

Noise-induced deafness includes acute acoustic noise deafness and chronic noise deafness, as follows:

1. Acute noise-induced deafness is such as receiving a knock injury instantly, and hearing loss and ear manifestations occur rapidly, with symptoms of dizziness, nausea, vomiting, and hearing loss. Because there is a very short period of noise exposure, and the symptoms of the ear appear, the hearing examination finds that it is neural deafness, and the diagnosis can be quickly confirmed;

2. Chronic noise-induced deafness, such as occupational exposure, such as hearing loss caused by 10-20 years, should also be combined with medical history, noise exposure in the environment, and the hearing examination done is a manifestation of neurological deafness. The combination of the two can be used to rule out other diseases, such as auditory nerve tumors and sudden deafness, and the diagnosis of noise-induced deafness can be made. Noise-induced deafness also has characteristic audiological manifestations, such as the Carhart notch, and hearing loss in the frequency band where the noise is located, which can be determined by doctors.

If there is a history of noise exposure, the diagnosis of noise-induced hearing loss can be made by detecting the ear symptoms of neural hearing loss.

Noise-induced deafness is a slow, progressive sensorineural tinnitus caused by the long-term influence of noise on hearing, which can be manifested as auditory fatigue in the early stage, and can gradually recover after leaving the noisy environment, and it is difficult to recover after a long time, eventually leading to sensorineural deafness, combined with tinnitus.

In addition to hearing damage, noise can also cause headaches, dizziness, insomnia, high blood pressure, electrocardiogram changes, and even affect stomach peristalsis and secretion.

Noise deafness, mainly when the noise exceeds 85 to 90 decibel intensity, damage to the cochlea, relevant examinations will find that the typical noise deafness is about 4000Hz, there will be typical hearing loss, once the relevant symptoms appear, it is recommended to go to the hospital for examination and **, otherwise it will lead to permanent hearing loss.

Noise-induced hearing loss, also known as noise-induced hearing loss (NIHL), is a kind of irreversible progressive and sensory hearing loss caused by long-term exposure to noise. Early manifestations of high-frequency hearing loss, which show V-shaped or U-shaped hearing loss in the range of 3 kHz to 6 kHz on the audiogram, and hearing valley (DIP) at 4 kHz, are important features of noise-induced hearing loss and an early sign of noisy hearing loss.

This is a slow, progressive development of hearing impairment caused by long-term exposure to noise, which improves early after removal from the noise environment and is difficult to recover over time.

The main harm of noise-induced deafness to the human body is to cause hearing loss and tinnitus, which will interfere with people's work and life, especially in a noisy environment, patients are unable to distinguish specific sounds, and there is still a certain harm to work and life.

Noise-induced hearing loss is a form of sensorineural hearing loss, which can produce hearing loss with high-pitched tinnitus from long-term exposure to noise. It affects the normal work, life and rest of the patient, and the long-term reversal can also lead to the patient's mental anxiety and emotional agitation, which is not conducive to normal physical and mental health. Attention should be paid to hearing protection and exposure to noise pollution should be avoided as much as possible to avoid hearing damage.

It is difficult to say whether this situation can be identified as an occupational disease from what you have stated, because it is a highly specialized issue. If it is sudden deafness, the identification of work-related injuries should be considered, otherwise, the issue of occupational diseases should be considered in combination with the working environment.

Suggestion: Seize the time to apply for the appraisal of occupational diseases, and the specific compensation items and amounts can only be calculated after the appraisal results are released, and the "Regulations on Work-related Injury Insurance" shall apply.

8. Grade 8 Identification Standards for Work-related Injuries and Occupational Diseases (15) Hearing loss in both ears = 41dBHL or 1 ear = 91dBHL;

9. Grade 8 Identification Standard for Work-related Injuries and Occupational Diseases (15) Hearing loss in both ears = 31dBhl or loss in one ear = 71dBhl;

10. Grade 10 Appraisal Standards for Work-related Injuries and Occupational Diseases (12) Hearing loss in both ears = 26dBhl, or one ear = 56dBhl.

"Diagnostic Criteria for Occupational Noise Deafness": Stipulates the diagnostic criteria and treatment principles for occupational noise deafness.

Hello friend, according to your question, this can generally be identified, don't worry.

Noise-induced deafness can be acute and chronic.

Acute is mostly caused by strong sound waves, but it can be conductive or neurotic, and it is related to the intensity and timing of the sound.

Chronic is mostly caused by working in a long-term noisy environment and not paying attention to hearing protection, and the early stage is obviously characterized by a V-shaped notch at 4kHz.

Noise-induced hearing loss is a slow, progressive sensory hearing loss that occurs due to long-term exposure of the hearing to noise, and can also be caused by ear fatigue. In the early stage, it manifests as auditory fatigue, which can gradually recover after leaving the noisy environment, and is difficult to recover over time, eventually causing sensorineural hearing loss. In addition to hearing damage, noise can also cause headache, dizziness, insomnia, high blood pressure, electrocardiogram changes, and can also affect gastric peristalsis and secretion.

Therefore, reducing or eliminating noise is a very important topic in today's environmental protection work. Noise deafness is commonly found in personnel working in highly noisy environments, such as naval engineers, tank pilots, aircraft field personnel, personnel who often wear headphones, wireless workers, riveters, forgers, textile workers, etc.

Any loud noise such as woodworking equipment, chainsaws, internal combustion engines, heavy machinery, gunfire or aircraft can damage the inner ear. Activities such as shooting, snowmobiling, flying, and diamonds are often associated with noise-induced deafness. Exposure to loud noise causes the hair cells of the inner ear cortises to disappear.

Although susceptibility to noise-induced hearing loss varies greatly between individuals, almost everyone will have hearing loss if exposed to noise of sufficient intensity for a sufficient amount of time. Any noise over 85db is damaging. High-frequency tinnitus is usually accompanied by deafness.

Hearing loss is first seen at 4kHz and progresses to lower and higher frequencies as exposure to noise continues. In contrast to most sensorineural hearing loss, 8 kHz has less damage than 4 kHz. **Sexual injury (acoustic trauma), which produces the same type of sensory hearing loss.

Noise is a combination of many chaotic sounds of different frequencies and different intensities. Noise hazard has become one of the main occupational hazards in the world today, and the harm of noise to human beings is multifaceted, and the damage to the auditory organ is the most obvious. Hearing loss, whether caused by exposure to a brief period of intense impulse noise or repeated noise exposure over a long period of time, is collectively referred to as noise-induced hearing loss, also known as noise-induced hearing loss.

Noise-induced deafness is common in people who work in noisy environments, such as ship engineers, tank pilots, aircraft field crews, textile mills and other industrial noise workers, as well as people who often wear headphones to listen to the Walkman**, and often go to karaoke rooms and discocories** halls! The degree of hearing loss is related to many factors, such as the duration of exposure to noise, the intensity and nature of the noise. The mechanism of damage caused by noise hearing loss is not well understood, and the following possible mechanisms are currently widely recognized:

1) Doctrine of mechanical damage. (2) Microcirculatory disorders. (3) Metabolic loss theory.

At present, there is no effective way to achieve noise-induced deafness, only to wear hearing aids, so prevention should be the main focus.
