Noise is a kind of pollution, which is extremely harmful to human ears. Long-term exposure to noise will cause certain damage to the eardrum of the ear, which is easy to cause hearing loss. Noise exceeding 85 decibels will cause hearing damage, but the hearing damage caused by short-term exposure to noise is only temporary, and will gradually recover after leaving the noise, but living in high noise for a long time will cause irreversible damage to hearing.
Noise will not only harm people's ears, but also affect people's sleep and reduce people's sleep quality. It is prone to frequent breathing and abnormal pulse. After getting up the next day, people will feel very tired and the work efficiency is particularly poor. After a long time, there will be symptoms such as insomnia, tinnitus and memory loss, which will seriously affect people's physical and mental health.
Noise will also have some adverse effects on the physical health of human body, because noise will make the human body have a nervous reaction and easily increase the secretion of adrenal hormones in the body. At this time, the heart rate and blood pressure will also change. Noise can also reduce the secretion of saliva and gastric juice in the body and reduce the amount of gastric acid. If you can't get rid of noise for a long time, the incidence of gastric ulcer and duodenal ulcer will increase.
Noise does great harm to people's eardrums, so you must protect your eardrums at ordinary times. Try not to work and live in those noisy environments. If you have to go, wear protective earplugs and try to avoid using headphones at ordinary times to prevent noise from irritating the eardrum and causing hearing damage. Don't dig your ears in daily life, let alone dig your ears with sharp objects, so as not to damage the eardrum by external forces.
