We often see people doing morning exercises wearing earphones listening to the radio. On campus, students can also watch while students are walking or riding bicycles and listening to music. I saw young people listening to rock music on the bus, and even the neighbors could hear the sound. Such long-term use of earphones can lead to noise-induced hearing loss.
Chinese scientists and technicians have studied the results, and the average age of people aged 23 or so, using earphones for 1 hour, 1-2.5 hours per day compared with the control group, there is a significant difference in hearing threshold. He suggested that the use of earphones can lead to noise-induced hearing loss, especially in the high-frequency region above 4000 Hz, significantly larger than the low-frequency region. The longer the earphone type is used, the more serious the hearing damage is. Some scholars have reported that the hearing loss of 4000 Hz can be caused first in the noise environment.
There are cochlear organs in people's inner ear. Scholars believe that due to long-term excessive stimulation, cell tissue metabolism is disordered, blood supply and oxygen supply are insufficient, resulting in damage to peripheral receptors, resulting in noise-induced hearing loss.
Remind everyone that when you have high-pitched tinnitus (such as humming, whistle, metal sound, etc.), you need to go to the hospital for ENT examination and treatment, which is very important to prevent deafness.
It is recommended to use earbuds for long periods of time and high volume to prevent noise-induced hearing loss.
There have been more and more hearing loss among young people who wear headphones to listen to music. This is because when the person wears the earphone, the outer ear canal is tightly blocked by the earphone. High volume audio sound pressure can directly enter the ear and damage the hearing, causing irreversible hearing damage.
Listening to music with headphones for a long time, hearing and fatigue will occur, causing hearing loss, the body will appear irritability, dizziness, insomnia, memory loss, inattention, slow thinking, abnormal psychological disorders, etc., for physical health Very harmful.
To this end, listening to music with headphones should pay attention to reduce the volume, soft and not harsh, and do not listen for a long time. Expert advice: Adults use headphones no more than 3 to 4 hours a day, adolescents because the auditory organs are not yet mature, should not exceed 1 to 2 hours a day, intermittent listening is appropriate.
