Tinnitus can be unilateral (that is, perceived only in one of your ears) or bilateral (perceived in your two ears), but it can also be described as inside the head. The perceived sensation can be constant, intermittent or pulsating.

According to its psychoacoustic characteristics, tinnitus can be simple if it is composed of a single noise or complex if it is composed of several noises simultaneously.
