Tinnitus is a hearing disorder experienced by a small proportion of the population in the world. It is experienced differently depending on the individual, but is described most commonly as a ringing in the ears, whistling, or buzzing sound, even when no sound is being produced anywhere.
In other words, tinnitus patients hear these sounds that do not exist. This may present as either continuously or periodically, and can also be classified into 2 types, objective and subjective tinnitus.
