The noise in a noisy environment is very loud. The background noise in KTVs, bars, etc. can be as high as 110 decibels, which can completely "steal" your hearing for a short period of time. The ground is noisy, which has a "pull-out" effect, resulting in higher indoor noise levels in high-rise buildings. You should open windows less often or always have noise-canceling earplugs available. When driving (at a high speed), wind noise may exceed 100 decibels, which is very harmful to hearing. In addition, loud honking, listening to music at high volume in the car, etc. can also cause damage to the ears. Many people like to pinch both sides of their noses and blow hard when blowing their noses. This will cause the snot to "rush" into the middle ear like surfing, causing the organs in the middle ear to "drowned" and leading to hearing damage. To prevent hearing loss, here are some guidelines for you : When wearing headphones for a long time, you can follow the "60-60" principle. When using headphones, the volume should not exceed 60% of the maximum volume and should not exceed 60 minutes a day. In places with loud noises, try to stay away from sound sources such as loudspeakers. It is not advisable to stay for too long in a place where the noise level is greater than 100 decibels. Colds caused by inflammation need to be treated promptly. 15%-25% of patients will develop otitis media, which affects hearing. Frequent ear picking will damage the protective oil in the external auditory canal and cause external auditory canal infection, which will then cause otitis media and hearing damage. |
