March 3 is the 25th National Ear Care Day, the Health Bureau of the Logistics Support Department of the Central Military Commission organized the "Love Ear Action" throughout the army, and the Department of Otolaryngology-Head and Neck Surgery of the PLA General Hospital focused on the noise challenges in military training, popularized the methods of ear care, improved the awareness of scientific training, and guarded the ear health of officers and soldiers. 
Military noise protection
The threat of noise in military training should not be underestimated. Officers and soldiers are often exposed to the strong noise generated by tanks, artillery and other equipment in their daily training, and if they do not respond effectively, it may lead to permanent hearing loss and even detonation deafness.
So, what noise levels
Will it cause hearing damage?
Studies have shown that long-term exposure to85 dB or moreThe risk of hearing loss increases significantly. In our everyday urban life, traffic noise often exceeds this safety standard. When the noise intensity exceeds140 decibels, hearing loss is almost inevitable, and the intensity is even lower than that of many firearms.
Once the following symptoms appearMedical help should be sought immediately
Hearing loss
Exposure to high-intensity noise may cause gradual or rapid hearing loss. In general, noise-induced hearing loss is of a nature of:Sensorineural hearing loss；If detonation is causedMiddle ear injury, which may be conductive or mixed,** with increased difficulty. 
Tinnitus
With hearing loss, persistent tinnitus may occur, especially in the damaged ear. 
Earache
*Ear pain can occur when middle ear damage such as tympanic membrane perforation occurs after a sound, and it usually resolves within a few days.
Headaches

Other symptoms
Noise can also cause:Nervous system, cardiovascular system, endocrine systemand other systems can be dysfunctional, which can lead to severe casesComa, shockand other serious consequences.
At present, there is no specific drug for deafness caused by military noise**, so preventive measures have become particularly important, and we should strengthen daily publicity and education"Dai, block, zhang, avoid, and treat" scientific prevention and control of the five-character formula
Wear: Wear protective gear scientifically
Blocking: Quickly block ears to effectively prevent noise
