When tinnitus occurs, you can go to a regular medical institution for relevant examinations, such as acoustic conductance impedance testing, otoacoustic emission, brainstem auditory evoked potentials, and cochlea electrograms, and other audiological examinations to identify the cause. Tinnitus is a relatively common phenomenon, and its causes are generally divided into physiological and pathological factors. According to the cause of tinnitus, it can be categorized as noise tinnitus, drug tinnitus, toxic tinnitus, traumatic tinnitus and so on.
