It’s the same mechanism that’s happening in people who feel a phantom limb sensation after losing a limb, explains Susan Shore, PhD, a professor of otolaryngology, molecular physiology, and biomedical engineering at the University of Michigan in Ann Arbor. With tinnitus the loss of hearing causes specific brain neurons to increase their activity as a way of compensating, she explains. “These neurons also synchronize their activity as they would if there were a sound there, but there is no external sound,” she adds.
No two patients and no two tinnitus cases are alike. As such, the “best” treatment option is often contingent on an array of factors unique to each patient. Moreover, successful management of tinnitus may require overlapping layers of treatment. ATA recommends that patients work with their healthcare provider(s) to identify and implement the treatment strategy that is best suited to their particular needs.
As of 2014 there were no medications effective for idiopathic tinnitus.[3][73] There is not enough evidence to determine if antidepressants[81] or acamprosate are useful.[82] While there is tentative evidence for benzodiazepines, it is insufficient to support usage.[3] Usefulness of melatonin, as of 2015, is unclear.[83] It is unclear if anticonvulsants are useful for treating tinnitus.[3][84] Steroid injections into the middle ear also do not seem to be effective.[85][86]
For some people, the jarring motion of brisk walking can produce what is called a seismic effect which causes movement in the small bones or contractions in the muscles of the middle ear space. You can experiment to find out if this is the cause by walking slowly and smoothly to see if the clicking is present. Then, try walking quickly and with a lot of motion to see if you hear the clicking. You can also test for the seismic effect by moving your head up and down quickly. 
Acoustic neuroma: This is a rare subjective cause of tinnitus, and includes a certain type of brain tumor known as an acoustic neuroma. The tumors grow on the nerve that supplies hearing and can cause tinnitus. This type of the condition usually are only noticed in one ear, unlike the more common sort caused by hearing loss usually seen in both ears. Causes of objective tinnitus are usually easier to find.

Exposure to loud noise. Loud noises, such as those from heavy equipment, chain saws and firearms, are common sources of noise-related hearing loss. Portable music devices, such as MP3 players or iPods, also can cause noise-related hearing loss if played loudly for long periods. Tinnitus caused by short-term exposure, such as attending a loud concert, usually goes away; both short- and long-term exposure to loud sound can cause permanent damage.
