What does tinnitus sound like?
The NIDCD tinnitus guide defines tinnitus as the perception of sound without an external source. It may be ringing, buzzing, roaring, clicking, hissing or humming; it can affect one ear, both ears or feel centred in the head.
Tinnitus is a symptom, not one disease. It is often associated with hearing loss or noise exposure, but earwax, infection, medication and other factors may be relevant. Do not stop a prescribed medicine because tinnitus is listed as a possible effect; discuss the timing and options with the prescriber.
Which features change the urgency?
Seek urgent medical care when tinnitus appears with sudden hearing loss, severe dizziness, facial weakness or other neurological symptoms, or after serious head injury. A sound that follows the pulse, persistent one-sided tinnitus, a major recent change, ear discharge or substantial distress also warrants professional assessment.
Discuss how tinnitus affects sleep, concentration and daily life with your clinician. A hearing aid is not a promised cure. The FDA OTC guidance advises medical care for one-sided ringing and other warning signs.
If tinnitus is causing thoughts of self-harm or you feel unable to stay safe, use emergency or crisis support in your country now.
What does assessment look for?
A clinician may examine the ears, review medication and health history, and arrange hearing testing. Describe whether the sound is pulse-synchronous, one- or two-sided, constant or intermittent, and what changed when it started. Bring a list of noise exposures and current medicines.
Imaging or specialist tests are not needed for every person; they depend on the history and findings.
What support is realistic?
There is no universal cure. If an identifiable cause such as impacted wax is present, treating it may help. For persistent tinnitus, support may include clear information, hearing aids when hearing loss is present, sound-based coping tools, sleep support and psychological therapies aimed at reducing distress.
Be wary of supplements, devices or programmes promising to erase all tinnitus. A credible service should state the goal, evidence, cost, risks and limits, and should not discourage appropriate medical or hearing assessment.
