After being in a noisy environment for a long time, I feel that my hearing has declined. How can I alleviate it?
The most direct harm caused by noise to the human body is hearing damage. Will being exposed to a noisy environment for a long time cause deafness? Long-term exposure to a noisy environment can cause temporary and permanent hearing damage to the human body. Under normal circumstances, noise below 85 decibels will not harm hearing, while noise above 85 decibels may be dangerous. Statistics show that long-term work in a noise environment above 90 decibels significantly increases the incidence of deafness.
The impact of noise on human hearing organs can be roughly divided into two categories:
The first is hearing fatigue that occurs in a noisy environment, that is, the hearing is damaged by strong noise. Leaving a noisy environment and still having a buzzing in your ears in a quiet place is called tinnitus. Tinnitus in turn masks hearing. At this time, if you talk to each other, you cannot hear the voices clearly. After a period of time, the tinnitus disappears and hearing can be restored. This is the phenomenon of hearing fatigue. Hearing fatigue is a temporary pathophysiological phenomenon, and the auditory nerve cells are not substantially damaged.
The second situation is when working in a strong noise environment for a long time. Under the stimulation of the noise, the auditory nerve cells undergo pathological damage and degeneration, which turns temporary hearing loss into permanent hearing loss, which is called Noise-induced deafness.
How to alleviate it?
1. Reduce the contact time with noise, and be sure to isolate yourself from noise when taking a rest. Or reducing the daily and weekly exposure time to noise can also reduce the incidence rate.
2. Hygiene monitoring. For people who work in a noisy environment for a long time, regular hearing examinations should be carried out to detect and treat early. People with sensorineural deafness and noise sensitivity should avoid working in strong noise environments.
3. Actively take measures or control the sound source. This is the most positive and fundamental approach.
4. For uncontrollable noise, you can use ear sound insulation. Wear earplugs, earmuffs, soundproof caps and other sound-proof equipment. For simplicity, you can plug the external auditory canal with cotton and then apply Vaseline. The sound insulation value can reach 30dB. .
5. Eat less high-fat foods. Excessive cholesterol concentration in the blood causes atherosclerosis in the blood vessel walls. Arteriosclerosis reduces the blood supply to the inner ear and causes malnutrition of the auditory organs, leading to hearing loss or deafness. Avoid using the Walkman for long periods of time. High-volume audio sounds can cause fatigue and damage to the hearing organs, leading to hearing loss and even deafness.
You can use certain methods to reduce the impact of noise at work. If it has seriously affected your health, it is recommended to put your health first. Noise seriously damages hearing and has a great impact on life and work.negative impact. Therefore, it is very important to stay away from noise and develop good living habits to protect your hearing. If an illness is discovered, you need to go to a professional hospital for treatment in time to more accurately eliminate hidden dangers and restore healthy hearing as soon as possible.
