Tinnitus, often referred to as a ringing in the ears, is the perception of sound when no external sound is present. It’s not a condition in and of itself, but rather a symptom of some other problem in the auditory system.

Tinnitus is generally classified into two categories: objective and subjective. Objective tinnitus is tinnitus your doctor can hear with a stethoscope or sometimes by simply listening in close proximity to your ear. This kind of tinnitus is rare, accounting for a small percentage of all tinnitus cases. Subjective tinnitus, on the other hand, is tinnitus only you can hear. Most people who experience tinnitus have subjective tinnitus.

Quick Fact


No two ears are the same, which is important to keep in mind when ensuring proper fit for hearing protective devices. During hearing protection testing, there is a <2mm difference in insertion depth between eighty-five percent of subjects’ left and right ears.
