In Brief
What is Fleeting Tinnitus?
“Fleeting tinnitus” is the common, non-medical term for a sudden, brief burst of ringing (often a pure tone) in one ear that fades away quickly, usually over a few seconds. In research and clinical writing it is often described as Sudden Brief Unilateral Tapering Tinnitus (SBUTT).
I can’t bring myself to call it SBUTT so let’s stick to what most people with tinnitus call it 🙂
People often describe a similar pattern:
A sudden high-pitched tone in one ear
A sense that hearing “drops out” or goes muffled in that ear
The sound then tapers and disappears, typically within seconds
This is different from long-lasting tinnitus (minutes, hours, or ongoing), which is a symptom itself with many possible causes.
What Causes Fleeting Tinnitus?
There is no single confirmed mechanism. The evidence suggests a few plausible pathways, and it is possible that different people experience fleeting tinnitus episodes for different reasons.
The main theories are:
1) Somatosensory and jaw-muscle trigger points
A small clinical study reported that some episodes appear closely related to trigger points in the lateral pterygoid muscle (a jaw muscle), with observations including association with trauma to that region and symptom reduction using jaw manoeuvres or dry needling (in some cases).
What this suggests (as a hypothesis, rather than an explanation) is that in at least some people, fleeing tinnitus episodes may be driven by trigeminal or somatosensory influences on auditory pathways, or by a reflex-type event linked to jaw musculature.
2) Middle-ear muscle spasm type explanations
Audiology commentary and clinical discussion propose that short-lived, intense tinnitus with a brief “tight” or muffled sensation could be related to small muscle contractions in or around the middle ear (for example, stapedius or tensor tympani activity), creating a transient change in the middle-ear that is perceived as both reduced hearing and a high-pitched tone.
This is plausible given the common experience (brief muffling then rapid recovery), but it is not particularly mapped to all cases.
3) A transient auditory dysfunction
A related phenomenon described in the ENT literature is transient auditory dysfunction (TAD): short-lasting (minutes), resolving, sensorineural hearing loss associated with tinnitus and no vestibular symptoms. This sits on the spectrum with “fleeting” events, but is typically longer than the classic few-second SBUTT description.
Papers describing TAD treat the underlying cause as uncertain, but it points to the possibility that a subset of “short tinnitus + hearing change” episodes may reflect a brief, reversible change at the cochlear or auditory-nerve level rather than purely middle-ear mechanics.
Transient auditory dysfunction: a description and study of prevalence
Most episodes are over before any measurement can be taken. That means the evidence base relies heavily on people logging and reporting their own symptoms, observational data, and small mechanistic studies.

What Can You Do About It?
It can be difficult if it’s brief and resolves itself. You can look at things like relaxation, stress reduction, tension relief around the neck and jaw area and see if they make a difference.
If you track occurrences, try to correlate it to things such as:
- Lack of sleep
- Stress
- Jaw tension
- Stiff neck
- Too much caffeine
- Bruxism
- Noise exposure
If you find a trigger you may find some relief in addressing it, though it can take time.
Getting Checked
You should always get checked out for anything that’s new or different, of if it’s causing you anxiety. Remember that tinnitus is a symptom and not a disease, so any changes are representative of something else happening.
Key things that you should book an appointment for (based on clinical guidelines) are:
- Sudden hearing loss
- Associated head injury, vertigo or facial weakness
- New or persistent pulsatile tinnitus (in time with heart beat)
AAA Sensorineural Hearing Loss
But you know what, you’re the best judge of your own body. If something doesn’t feel right then go get it checked out. It’s better to err on the side of caution and give your self peace of mind.
Describe
If you seek medical help you should go prepared with the right information. Consider beforehand:
- Which ear
- Duration
- Type of noise
- Type of muffling or ear fullness and for how long
- How often it’s happened
- Any differences each time it’s happened
- Anything new in regard to stress or muscular tension
- Any stress, sleep issues, headaches, anything that could be related
- Any trigger you have noted
