The feeling of sound passes through the feel and analysis of the auditory system. External sound waves enter the external auditory canal, causing the tympanic membrane to vibrate. The vibration frequency of the tympanic membrane is the same as the sound wave, and the amplitude depends on the intensity of the sound wave. When the tympanic membrane vibrates in the inner and outer directions, the stirrup floor on the vestibular window vibrates through the three auditory bones, causing vibration of the vestibular lymph of the inner ear.
The vestibular membrane, the endovascular lymphatics, the basement membrane, the tympanic perilymph, and the round window membrane are sequentially vibrated. The vibration of the basement membrane constantly changes the relative position of the hair cells of the spiral and the covering membrane, so that the hair cells emit nerve impulses, and the cochlear nerve fibers generate action potentials. It forms hearing through the medulla, through the hypothalamus to the medial geniculate body, and finally to the temporal lobes of the cerebral cortex.
So what if we have a hearing loss situation?
First, be nervous, don’t panic, and maintain a good state of mind. If you are in a state of urgency for a long time, it will cause the autonomic nerves in the body to lose normal regulatory functions, causing ischemia and hearing impairment in the inner ear.
Then you need to seek medical treatment in time. When you find that your hearing is declining, you need to go to the hospital for treatment. The sooner you treat, the more likely you are to recover.
It can also be carried out during the recovery period on weekdays.Ear massageIncreases the blood circulation of the inner ear and protects the hearing.
Eat more foods rich in iron, such as seaweed, shrimp black fungus, black sesame and so on.
