Usually noise exposure, hearing loss, or earwax - rarely dangerous. Ringing in one ear only, pulsing with your heartbeat, or sudden hearing loss needs prompt care.

What does it mean if my ears are ringing?
Ringing, buzzing, or hissing in your ears - tinnitus - is extremely common and usually ties to one of a handful of causes. NIDCD lists the big ones: noise exposure, including concerts, earbuds at high volume, and loud work; age-related hearing loss, where tinnitus often arrives first; earwax blocking the canal, which is the most fixable cause on the list; and a long roster of medications, including high-dose aspirin, some antibiotics, and some blood pressure drugs. Most tinnitus is annoying rather than dangerous, and management works: avoid silence, since quiet rooms make ringing louder - a fan or low background sound at night helps; protect your ears from further loud noise; and review medications with your clinician. If it is new or bothersome, a hearing test is the smart first step, because treating hearing loss often turns the ringing down. The patterns that deserve faster attention: ringing in only one ear, which should always be checked; ringing that pulses with your heartbeat; hearing that drops suddenly - that one is an emergency, treatable only on a short clock; and tinnitus with dizziness, which points to inner-ear conditions needing their own workup.
