What is tinnitus?
Tinnitus is a hearing sensation that is perceived even in a silent environment. Certain individuals will perceive a roaring sound, such as a motor, whereas others may perceive a more crackling sound. It is estimated that nearly 5 to 15% of the adult population is affected by tinnitus. Although it is known to cause different levels of discomfort in certain individuals, tinnitus is generally not harmful, but requires special attention.
