There are two main forms of tinnitus:
- Tonal tinnitus is the most common type of tinnitus and describes the perception of a near-continuous sound or overlapping sounds with a well-defined frequency, e.g., whistling, ringing, buzzing.
- Non-tonal forms of tinnitus include humming, clicking, crackling and rumbling.
For some, their condition is something they only notice when they actively think about it. For others, tinnitus makes it difficult to focus, relax, and even sleep.
