Noise deafness generally refers to the sensorineural deafness caused by long-term exposure to noise environment. In general, the hearing loss caused by this kind of deafness is basically irreversible.
So how do we judge whether we have or are likely to have noise deafness?
Some professionals have made statistics. If you work and live in an environment of more than 80 decibels, it will cause discomfort in the ear, and at the same time, it may cause symptoms such as tinnitus and earache. If the decibels are increased for another stage, after reaching 90 decibels, the damage to the ear is irreversible.
Generally speaking, noise deafness will not cause deafness immediately, and will first appear the symptoms of hearing fatigue. Long term exposure to noise environment will cause hearing fatigue, which will reduce the sensitivity of your ears to sound. Generally speaking, after leaving the noise environment, it will gradually recover. Conversely, if you continue to be in the noise environment under the state of hearing fatigue, it will cause noise deafness.
Which people are likely to suffer from noise deafness?
In short, people living for a long time or working in noisy environment are at risk of suffering from noise deafness. Many of them work more because of their work, and are forced to work in those environments, such as some bars, KTV staff, large machinery factory staff, who are potential deaf patients.
Generally, if you stay in this kind of environment for a long time, you should go to a quiet environment to relax your ears a little. But for the workers in the machinery factory, many of them work in the assembly line. It’s impossible for you to stop alone, so they can’t leave without permission for most of the time, so they can choose to wear one at work Noise reduction earplugs, which can effectively reduce the sound of nearly 30 decibels, can protect the hearing of the ear.
If you have been suffering from noise deafness, you should go to the hospital for treatment first to see if it is effective. If not, you need to wear hearing aids in time. First, go to a hearing test to see how much your hearing loss is, and then wear the appropriate hearing aids according to the advice of the examiner. After wearing the hearing aid, you can not only hear the previously inaudible sound, but also protect the residual hearing and alleviate the speed of hearing loss.
