The formation mechanism of tinnitus is more complex, the formation of tinnitus is mainly physiological, objective, neurological, conductive, each with a different formation mechanism. 1. Physiological: physiological tinnitus is mainly in the human body breathing movement, blood flow, as well as blood vessel pulsation and other circumstances, due to physiological movement of the sound, due to the distance from the ear is relatively close to the ear, so in a quiet environment will be heard in the ear a slight sound. 2. Objective: Objective tinnitus does have sound, but it is not an external source of sound, but in the vicinity of the human ear, due to the throat, blood vessels, or small muscles in the middle ear sound, due to elevated blood pressure, arterial clogging due to factors such as blood vessel pulsation sound constitutes tinnitus. 3. Neurogenic: Neurogenic tinnitus is caused by abnormalities in some of the nerves of the auditory system, such as Meniere’s disease, medication, or noisy environments, or trauma to the auditory system, all of which affect the auditory system, resulting in tinnitus. 4. Conductive: Conductive tinnitus is caused by abnormalities in the auditory system, such as otitis media, otitis externa, tympanic membrane penetration, tumors, intracranial lesions and other diseases, resulting in impaired conduction of sound, which reduces the ability to hear the outside world, thus making people feel tinnitus. Tinnitus formation mechanism is more complex, if long-term tinnitus, it is recommended to go to the hospital in a timely manner to improve the examination, a clear diagnosis, to give targeted treatment.
