Will working in a noisy environment cause tinnitus?
The sounds that affect people’s work, study and rest are called noises. Some appear in the workplace, and some exist in daily life. After living in a noisy environment for a long time, some people will gradually develop symptoms of tinnitus. At this time, you should be careful, because noise-induced hearing loss is eroding your hearing health.Working under noise for a long time will cause great damage to hearing. This damage is not felt in a short period of time. It damages the hair cells of the inner ear, causing noise-induced hearing loss. This damage is It is impossible to reverse, that is to say, it cannot be cured. As for tinnitus, this is just one of the symptoms. Friends who want to work under noise must take protective measures. Violence and prolonged noise exposure can lead to hearing loss and tinnitus. People working in high-intensity noise environments should pay attention to noise protection, such as reducing noise sources or wearing protective earmuffs, earplugs, etc. In addition, be careful not to use Walkman headphones in a noisy environment for a long time and at high volume.
During the production process, long-term exposure to a noise environment with an intensity greater than 85 decibels (dB) can cause damage to the cochlea. Short-term exposure to noise may only cause temporary hearing loss, but over time it will gradually turn into permanent hearing loss. The initial manifestations are hearing loss in the high frequency band 3000 to 6000 Hz (Hz), and the tissue cells at the base of the cochlea are damaged, degenerated, and necrotic. As the exposure time to noise increases, the condition worsens and develops to the speech frequency band 500, 1000, and 2000 Hz, eventually causing most of the cochlea. or all, especially when the top is damaged and significant speech-hearing impairment occurs.
The impact of noise on the hearing organs can be roughly divided into two situations: one is hearing fatigue in a noisy environment. Because the hearing organ is stimulated by sound, the body will inevitably make appropriate adjustments.Decent reaction. However, when this stimulus is too strong, such as exceeding 90 decibels, it can damage the hearing organ, that is, damage the hair cells of the spiral organ. At this time, even if you leave the noisy environment, there will still be a buzzing in your ears in a quiet place. This kind of tinnitus in turn masks hearing. If you talk to someone at this time, you will feel that you can't hear what the other person wants to say. After a period of time, the tinnitus disappears and hearing is restored. This is the phenomenon of hearing fatigue.
Another situation is that if you work in a strong noise environment for a long time, the spiral hair cells are often exposed to noise stimulation, which will cause damage to the hair cells and degenerative changes. The degree of disease is closely related to the intensity, frequency and length of service of the noise.
If you find that you have been in a noisy environment for a long time, whether it is work or living environment, or you feel that you have tinnitus for a period of time, you should pay attention. Arrange time for yourself as soon as possible to have a professional hearing test, understand your hearing situation in a timely manner, and listen to expert advice, such as: changing work or living environment, if not, you can choose a suitable hearing aid to protect your residual hearing, etc. wait. Even if the examination report says that you are normal, you should not take it lightly, because hearing loss can occur unconsciously, so you should go to a professional institution for regular examinations to ensure early detection and early treatment.
