What is tinnitus?
Tinnitus is the perception of ringing, buzzing, humming or another sound when there is no matching external source. It may affect one or both ears and may be intermittent or persistent. Tinnitus itself is not a single diagnosis: it can accompany different ear, hearing or general health conditions.
When should assessment not be delayed?
Seek prompt medical assessment if tinnitus starts suddenly together with a sudden change in hearing, marked vertigo, a new neurological symptom, or a pulse-synchronous sound. Persistent one-sided tinnitus also deserves medical review even when it is not an emergency.
What may an audiologist check?
The visit starts with the history: when the sound began, whether it is one-sided, how hearing feels and what other symptoms are present. Depending on the clinical question, otoscopy, pure-tone audiometry, tympanometry and acoustic reflex testing may be used. These tests do not always identify one single cause of tinnitus, but they help define what needs further assessment.
What can you note before the appointment?
It is useful to write down whether the sound is constant or intermittent, one-sided or bilateral, whether hearing has changed, whether there is dizziness or pressure, and which medicines you currently take. Avoid self-prescribing treatment because the appropriate next step depends on the pattern of symptoms.
Key point
The most useful question is not simply whether tinnitus is present, but whether hearing has changed and whether any accompanying features need urgent review. A structured hearing and ear assessment can make that distinction clearer.
What information matters when tinnitus is evaluated?
The word “tinnitus” describes a symptom, not one single disease. For an assessment, it helps to know whether the sound is in one ear or both, constant or intermittent, pulse-synchronous or non-pulsatile, and whether hearing has changed. People may describe ringing, buzzing, humming, hissing, clicking, roaring or other sounds. These descriptions do not diagnose the cause, but they help determine the appropriate next step.
Why do one-sided or pulsatile symptoms deserve specific attention?
Persistent unilateral tinnitus and a sound that follows the heartbeat should be specifically mentioned to a clinician because these patterns can change the medical work-up. The purpose is not to assume a serious cause, but to make sure the symptom is characterised correctly and that an appropriate ENT or medical assessment is considered.
If tinnitus appears together with a sudden marked change in hearing, severe new vertigo or new neurological symptoms, medical assessment should not be unnecessarily delayed. Website information cannot replace urgent care when acute symptoms are present.
What might an audiology appointment include?
The evaluation usually starts with the history of the symptom and examination of the ears. Depending on the clinical question, pure-tone audiometry may measure hearing thresholds, speech testing may assess functional speech understanding, and tympanometry or acoustic-reflex testing may add information about middle-ear and immittance findings. Some presentations require additional tests or referral to another clinician.
The purpose of these tests is not to “measure tinnitus” as a single number. They help identify associated hearing changes, describe the auditory system more accurately and guide decisions about what should be evaluated next.
Can tinnitus be real when a routine audiogram is normal?
Yes. A conventional pure-tone audiogram measures detection thresholds at selected frequencies; it does not capture every aspect of real-world listening or the tinnitus experience. A person can report tinnitus even when routine thresholds fall within the expected range. Symptoms, noise exposure, difficulty understanding speech and other clinical findings still need to be considered alongside the audiogram.
What is useful to note before the appointment?
Write down when the sound began, whether it is one-sided or bilateral, constant or intermittent, whether it follows your pulse, and whether you have noticed a change in hearing, ear pressure, dizziness or sensitivity to sound. Bring a list of medicines and relevant previous hearing tests. Do not stop prescribed medication on your own; possible medication-related effects should be discussed with the clinician who manages the treatment.
