Hello, noise deafness generally does not cause immediate deafness, will first appear symptoms of auditory fatigue, long-term exposure to noise will cause auditory fatigue, will make your ears less sensitive to sound, generally after leaving the noise environment will gradually recover, on the contrary, in the state of auditory fatigue continue to be in the noise environment, it will cause noise deafness.

Hello, sudden deafness is generally associated with viral infections, labyrinthine edema, vascular lesions, etc. If it is caused by viral infection, antiviral drugs, vasodilators, drugs that reduce blood viscosity and thrombolytic, neurotrophic drugs, and energy preparations should be used in a timely manner, which can be assisted by hyperbaric oxygen**. It is a complete set of high-efficiency programs such as acoustic information instrument, acupoint injection and syndrome differentiation of traditional Chinese and Western medicine, which can improve the microcirculation of the head and neck, enhance oxygen supply, nourish nerves, improve the internal environment of the auditory pathway, activate damaged auditory nerve cells, stimulate the body's self-two-way benign regulation, and twist the progressive aggravation of the lesion into gradual healing progression, so as to improve the effect of hearing and achieve the purpose of consolidating the foundation.

Noise-induced hearing loss is a type of hearing loss that occurs slowly and progressively due to the long-term impact of noise, and is mostly sensorially deaf.
Noise over 85 90db is damage to the cochlea, resulting in noise-induced deafness.
The main symptoms are progressive hearing loss and tinnitus. Early hearing loss is at 4,000 Hz and, therefore, has no significant effect on ordinary speech and is only detected on audiometer examination. Later, hearing damage gradually progressed to high and low frequencies, and eventually generally declined.
At this time, he feels hearing impairment, and in severe cases, he can be completely deaf. Tinnitus and deafness can occur at the same time or alone, often as high-pitched tinnitus.
Noise can also cause headaches, dizziness, insomnia, high blood pressure, etc., affecting gastric peristalsis and secretion.
Basis for diagnosis. 1.Have a clear history of noise exposure, i.e., a history of long-term overtime work in environments above 85dB (a).
2.Pure tone electro-audiometry is inductive deafness.

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.

Deafness is due to noise.
The sounds we hear on a daily basis can be divided into two categories: musical sounds and noise. The sound produced by the periodic and regular vibration of the object is more pleasant to the ear and gives people a comfortable feeling, it has a certain frequency and waveform, this kind of sound is called musical sound, such as singing, musical instrument sound, birdsong and so on. On the contrary, the sound produced by the non-periodic and rhythmic vibration of an object, without a certain frequency and waveform, is harsh and unpleasant, and this kind of sound is called noise, such as the sound of factory machines turning, the sound of vehicle engines, the roar of aircraft, the sound of construction site operations, or the sound of some percussion instruments.
Noise is harmful to the human body.
Modern acoustics defines noise as unwanted sound. For this reason, the concept of sound and noise is relative, with music that is musical to some and disturbing noise that may be undesirable for others. The most typical example is the popular disco** of modern times, which has a fixed pitch and can be displayed on staves and staves, which intoxicates some people and distracts others by its noise.
Tinnitus, regardless of its pitch and timbre, is an unwanted sound and should therefore be classified as noise.
I hope I can help you with your doubts.

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.

In the early days, there is only high-pitched tinnitus, which becomes intermittent and persistent. Initial deafness is reversible and usually recovers after isolating noise. The early hearing damage is in the non-verbal area of 3 kHz and 4 kHz, so it is not noticeable, and gradually involves 6 kHz 8 kHz and 2 kHz 1 kHz at both ends, which can become obvious irreversible hearing loss.
Hearing loss can continue to occur in a noisy environment, with rapid impairment in the first 10 years, and then slow development and spread to low frequencies, and in the late stage, it may be a low flat curve or island hearing, but it is rare to be completely deaf.

There are many causes of deafness, some are pathological, and some are caused by strong noise from the outside world, you should go to the hospital for a check-up to find out the cause and treat the symptoms.
-
Noise can cause deafness, and there are many causes that need to be checked to know the cause.
-
There are many causes of deafness, such as external or internal factors, but noise does have an image of the ear.
-
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.
