Why do I randomly hear a high-pitched noise?
Tinnitus happens when we consciously hear a sound that does not come from any source outside the body. It is not a disease, but a symptom of an underlying problem. The noise is usually subjective, meaning that only the person who has tinnitus can hear it. The most common form is a steady, high-pitched ringing.
