Most forms of tinnitus are fantastic sensations activated by noxious nerve remodeling caused by hearing loss, and sounds arriving at the ear cause inhibition or excitation of cochlear auditory nerves, which cause inhibition and excitation of the central nervous system in the corresponding region of the brain through conduction of the nervous system, and balanced inhibition and excitation form normal hearing, and breaking this balance easily causes nerve remodeling, resulting in excessive discharge of neurons in a partial region, affecting the surrounding normal neurons, and causing a brain tinnitus response.
Research shows that the central nervous system input reduction is an important tinnitus generating factor, most tinnitus patients can find areas with hearing sharply reduced clinically, even tinnitus patients with normal hearing on the surface can find areas with hearing sharply reduced when the areas near tinnitus frequency points are subjected to fine hearing threshold examination, the hearing reduction causes the transmission of sound signals in a reduced frequency range to be weakened, under the same external environment sound, neurons of a brain center corresponding to the hearing reduction frequency are weaker in sound signal intensity than peripheral neurons, the neurons in the areas can be over-discharged, the situation of the peripheral neurons is influenced, and therefore the condition that the brain generates tinnitus reaction is formed, and under the condition, the tinnitus can be caused by the reduction of brain control force caused by certain reasons such as mood deterioration, diseases, stimulation and the like.
