First of all, let us briefly understand our ears. It is composed of three parts: the outer ear, the middle ear, and the inner ear. The outer ear receives sounds from the outside and causes the tympanic membrane to vibrate along the ear canal. The vibration of the tympanic membrane of the middle ear causes Three small bones, the malleus, stapes and incus, vibrate and transmit sound to the inner ear. The inner ear can generate nerve impulses, which are converted into nerve energy along the auditory nerve, so that the sound information is transmitted to the brain. When you listen to headphones for a long time, the sound pressure directly enters the ear and is transmitted concentratedly to the thin eardrum without any buffering room. This stimulates the endings of the auditory nerve. The stimulating impulse causes abnormal excitement of the auditory nerve, which can easily cause auditory fatigue. . It can also cause some systemic adverse effects. The main symptoms include tinnitus, mild hearing loss, double hearing, and slight ear pain. There have also been cases of explosive deafness; some students also experience dizziness, brain swelling, and difficulty concentrating. Concentration, sensitivity of thinking and reactions, memory loss, and irritability and impatience may also occur. For friends who wear headphones while riding, it will also affect traffic safety.

Hearing damage is irreversible, so we must not ignore it. Pay attention to the correct use of headphones: the volume should be enough to hear clearly, and the time should not exceed 1 hour a day. If you find tinnitus and hearing loss, you should go to the hospital for examination in time and stop using headphones.
