Long-term exposure to ultra-high decibel sounds such as shooting and explosion without proper protection may cause hearing damage, which is called “knock deafness”. Artillery often suffers from “knock deafness”.
Manifestations of blast deafness
The damage of noise to ears generally develops from temporary hearing loss to permanent hearing loss.
At first, you may only feel the buzzing of your ears, that is, tinnitus, and then slowly progress to hearing loss.
People who have been exposed to strong noise for a long time may also feel headache and dizziness, which will affect sleep and cause problems such as increased blood pressure, decreased immune function, gastrointestinal discomfort, etc.
With the extension of the exposure time to noise, or the hearing loss caused by the previous exposure to noise has not been fully recovered, and it is necessary to contact again in a short period of time, irrecoverable hearing damage may be caused.
Treatment of blast deafness
Temporary hearing loss does not need treatment, as long as you stay away from the noisy environment and have a full rest, you can completely recover.
Permanent hearing damage cannot be recovered autonomously, and can only rely on wearing hearing aids, implanting vibration sound bridges, cochlear implants and other equipment, so prevention is very important.
Prevention of blast deafness
Personal prevention is mainly to strengthen protection, including:
In training and tasks, wearing personal protective equipment such as earplugs, earmuffs and helmets can effectively protect hearing organs.
Regular health checks, especially hearing tests, are carried out.
