Abstract

The origin of tinnitus is not definitely known. That it must arise from abnormalities in the auditory system, either locally or in the nerve mechanism, is obvious. Two types of tinnitus are differentiated—the subjective type, which is heard only by the patient, and the objective type, which can be heard also by an observer.

There will be considered here only the objective type, which may be either vascular or muscular in origin. The vascular type occurs most commonly in the adult. The muscular type is less common and is found particularly in children. The vascular type of objective tinnitus is heard with the aid of a stethoscope or an auscultation tube, while the muscular variety can often be heard by an observer at a distance of from 1 to 2 feet (30 to 60 cm.) from the patient.
