By comparing the clinical manifestations, ABR parameters and cerebral cortex blood oxygen levels of chronic tinnitus patients and healthy subjects under two different body states, the peripheral-central correlation of chronic tinnitus patients was explored, and the modern scientific significance of the theory of "two ears connecting the brain" was initially expounded.
