Hearing loss in the left ear may be a congenital genetic factor or an acquired factor. A small number of people are born with defects, and genes can cause abnormal ear structure, leading to hearing loss. Deafness is mostly caused by acquired factors, such as excessive life pressure, frequent staying up late, physical exhaustion, etc., which will easily lead to sudden deafness. Hearing loss in the left ear may be caused by another external impact or long-term exposure to a very noisy environment.
In addition to hearing loss, a particularly serious hearing abnormality, many people now have hearing loss, mainly because they wear headphones for a long time, don't pay attention to ear hygiene, and often stay up late, resulting in decreased immunity. These situations can be avoided in most cases, and hearing loss will bring a lot of inconvenience to people's lives, so we must learn to protect our hearing.
For example, don't wear headphones for a long time, and it is best not to use headphones for more than an hour every day. When using headphones, don't turn the volume to an uncomfortable level for sound effects. Develop correct living habits, insist on going to bed early and getting up early, and strengthen physical exercise. Try not to go to places with excessive noise for a long time, and cover your ears even if you want to go.
