Nowadays, many young people like to wear headphones to listen to music, and even wear headphones when they sleep. Do you know that in the long run, it will have serious consequences. Mr. Chen, who lives in Jinyin lake, is a music "enthusiast" and has participated in the "good voice of China". For a long time, he has formed the habit of listening to music while working and sleeping with headphones. "I like to wear a good pair of headphones, turn the volume to the maximum and listen to music. It's like being at a concert. It's very enjoyable!" Mr. Chen said. However, a few months ago, he suddenly found that he could not hear clearly and often had tinnitus. He came to the Department of Otolaryngology of Wuhan Red Cross Hospital and was diagnosed as "binaural sensorineural deafness". Li Ling, director of the Department of Otolaryngology of the hospital, introduced that there are not a few patients with hearing loss and tinnitus caused by wearing headphones in normal diagnosis and treatment. Most patients have incentives such as overwork, mental tension and emotional fluctuation before the onset of the disease, and some patients may have a history of cardiovascular and cerebrovascular diseases. "There is a certain limit to the ear's tolerance to sound. When the volume is higher than 50 dB when wearing headphones, it will lead to excessive energy metabolism of human ear cells and microcirculation disorder of inner eardrum cells, temporary hearing damage and even severe hearing loss." She stressed that often wearing headphones must be harmful to the ears, whether headphones or in ear headphones. It is common to cause external auditory canal inflammation after wearing headphones, especially in ear headphones, which are often stuffed into the ear canal to stimulate repeated inflammation of external auditory canal cartilage. If you listen to too much sound for a long time, you can produce tinnitus, which is mostly manifested as cicada like buzzing or current sound. Once tinnitus occurs, it is difficult to cure it. Li Ling said that generally speaking, using headphones for no more than 60 minutes a day belongs to the safe range, and we should give our ears enough rest time. Wear headphones to listen to music when sleeping. If you wear headphones all night, your hearing will be extremely damaged. The sound contact area of in ear headphones is relatively small and the pressure on the inside of the ear is relatively large; Headphones have large contact area and relatively small pressure, and the stimulation to some cells, tissues and mucous membranes in the ear will be smaller. So try to use headphones and choose noise reduction headphones. Be sure to turn down the volume and reduce stimulation. (outlook new era)
