While it is commonly referred to as “ringing in the ears,” tinnitus can also be experienced as hearing a buzzing, hissing, whistling, swooshing, or clicking. Stemming from the Latin tinnire, “to ring,” tinnitus can be pronounced TINN-itis or tin-EYE-tis. It’s important to understand that tinnitus is a symptom, not a condition itself. “It is a symptom that something is wrong in the auditory system, which includes the ear, the auditory nerve that connects the inner ear to the brain, and the parts of the brain that process sound,” according to the [National Institute on Deafness and Other Communication Disorders (NIDCD).](https://www.nidcd.nih.gov/health/tinnitus) Brief, spontaneous tinnitus, lasting seconds to minutes, is experienced by nearly everyone. Temporary tinnitus that lasts minutes to hours routinely happens after excessive noise exposure. While it usually resolves on its own, the tinnitus is a sign that the ear has been damaged by the loud sound. Chronic tinnitus occurs for three months or longer. ### How Common Is Tinnitus? ![Credit: Mayo Clinic](https://images.squarespace-cdn.com/content/v1/58b8bb4ee58c6261065836a1/1614536475475-HSQ1IUF0FPI5D0B0G7KM/Tinnitus%2BHair%2BCell%2BLoss.jpg) Excess noise can damage sensory hair cells in the inner ear, leading to reduced sound input to the brain.
