Medline NLM definition: Sounds that are
perceived in the absence of any external noise source which may take the
form of buzzing, ringing, clicking, pulsations, and other noises.
Objective tinnitus refers to noises generated from within the ear or
adjacent structures that can be heard by other individuals. The term
subjective tinnitus is used when the sound is audible only to the affected
individual. Tinnitus may occur as a manifestation of COCHLEAR DISEASES;
VESTIBULOCOCHLEAR NERVE DISEASES; INTRACRANIAL HYPERTENSION;
CRANIOCEREBRAL TRAUMA; and other conditions.
