How to relieve hearing loss during the long-term under noisy environment?Cindy
There are many reasons for hearing loss. If you touch the machine for a long time, sounds and other sounds can cause the tiny blood vessels of the inner ear to be paralyzed. The blood supply to the inner ear is reduced and hearing is greatly reduced. Therefore, avoiding or reducing noise interference is an important part of protecting your hearing.
Long-term in a noisy environment, feeling hearing loss, how to ease?
The most direct hazard to noise is the hearing impairment. Will you be deaf for a long time in a noisy environment? Long-term in a noisy environment can cause temporary and sustained hearing damage. Typically, noise below 85 decibels is not harmful to hearing, and noise above 85 decibels can be dangerous. Statistics show that the incidence of deafness increases significantly when working in a noisy environment for more than 90 decibels.
The effects of noise on human hearing organs can be broadly divided into two categories:
The first is hearing fatigue that occurs in noisy environments, where hearing is compromised by strong noise. When leaving the noisy environment, it still makes a harsh sound in the quiet place of tinnitus. Tinnitus covers the hearing again, and if you talk to each other, you will not hear the sound. After a while, the tinnitus disappeared and the hearing recovered. This is a phenomenon of hearing fatigue. Hearing fatigue is a temporary pathophysiological phenomenon in which the auditory nerve cells are not substantially damaged.
The second case is that working in a strong noise environment for a long time, the pathological damage and degeneration of nerve cells under the stimulation of noise, temporary hearing loss becomes permanent hearing loss, called noise deafness.
How to ease it?
- Reduce contact time with noise and ensure isolation from noise during breaks. Or reduce the time of daily and weekly exposure to noise, and reduce the incidence.
2, health monitoring, for people who work in a noisy environment for a long time, regular check hearing, and early detection of treatment methods. People with sensorineural deafness and noise sensitivity should avoid working in noisy environments.
- Actively take measures or control the sound source. This is the most positive and basic method.
- For uncontrollable noise, ear noise can be taken and earplugs, earmuffs, soundproof caps and other soundproofing equipment can be worn. Simple, you can use cotton cloth to close the external auditory canal, and then apply Vaseline, the sound insulation value can reach 30dB.
- Eat less fatty foods. The concentration of cholesterol in the blood is too high, resulting in atherosclerosis of the vessel wall. Hardening of the blood vessels reduces the blood supply to the inner ear, and the hearing organ is malnourished, resulting in hearing loss or deafness. Avoid using the Walkman for a long time. High volume audio can cause fatigue and hearing organ damage, resulting in hearing loss and even deafness.
In the work, there are certain ways to reduce the impact of noise. If it has seriously affected your health, then the recommendation is to take the body as the most important. Severe noise damages hearing and has a large negative impact on life and homework. So stay away from noise and develop good habits to maintain hearing is very important. If you find the condition, you need to go to a professional hospital for treatment in time to more accurately eliminate the hidden dangers of the disease and restore healthy hearing as soon as possible.
