objective tinnitus
   The term objective tinnitus refers to a rare type of * tinnitus (i.e. 'ringing in the ears') characterized by a click or a crackling noise that can be perceived not only by the individual affected but also by a third person, either with the aid of a stethoscope, in the areas surrounding the ear, or without the use of any artificial aids - as emanating from the affected individual's ear. It has been estimated that objective tinnitus makes up no more than 5% of all cases of tinnitus. Objective tinnitus is attributed to a variety of muscular and vascular conditions. It may present as a sound that beats simultaneously with the individual's pulse, in which case it is called * pulsatile tinnitus. The term objective tinnitus is used in opposition to * subjective tinnitus, which denotes a type of tinnitus that can only be perceived by the affected individual.
