Īlthough most cases of tinnitus are caused by hearing loss at the cochlea, studies suggested that there may be a connection between epilepsy and tinnitus (16 ). This hyperactivity in the auditory part of the brain leads to an excess of electrical noises that take the form of tinnitus. Such a response is the brain’s way of compensating for hearing loss. This action is equivalent to using more antennas to get a better signal for one’s radio. When the hair cells in the cochlea are damaged, the brain makes an increased effort to detect the nerve signals it cannot receive by increasing neuronal activity. In the cochlea, the sounds humans hear become electric impulses or nerve signals, which the brain interprets as sound frequencies (15 ). The cochlea is a spiral-shaped bone that plays an essential role in the body’s auditory process. Tinnitus usually occurs when hair cells in the cochlea are damaged (14 ). On the other hand, cases of objective tinnitus allow patients to hear existing sounds, such as heart murmurs (a sound accompanying abnormal heartbeats) (13 ). Most people experience subjective tinnitus, in which they only hear phantom sounds (12 ).
