A rhythmic whooshing sound in your ear that pulses with your heartbeat is almost always pulsatile tinnitus, and unlike the steady ringing most people associate with tinnitus, it usually has a findable physical cause. That distinction matters because finding the cause often means the sound can be stopped or significantly reduced with targeted treatment. The challenge is that the list of possible causes runs from harmless to serious, and the whooshing is frequently misidentified in primary care as ordinary tinnitus and left uninvestigated.
Why Your Ear Sounds Like a Washing Machine
Pulsatile tinnitus is the medical term for a sound you hear in sync with your heartbeat. It affects fewer than one in ten people who have any form of tinnitus, making it uncommon enough that many doctors don’t immediately recognize it as a separate condition requiring its own workup.1PubMed Central. Increasing awareness with recognition of pulsatile tinnitus for nurse practitioners in the primary care setting: A case study People describe it as whooshing, swooshing, pulsing, or a rhythmic humming. It can affect one ear or both, and it may be constant or come and go depending on position, exertion, or time of day.
The sound is real, not imagined. In many cases a doctor can actually hear it too by placing a stethoscope near your ear or skull. When the sound is audible to an examiner it’s called “objective” pulsatile tinnitus, and that’s a strong signal that blood flow near the ear is creating turbulence loud enough to transmit through bone and tissue into the inner ear. Even when a doctor can’t hear it externally, the mechanism is usually the same: blood moving through or near structures close to the cochlea in a way that generates an audible vibration.
The Most Common Culprit Is Venous
The majority of pulsatile tinnitus cases trace back to veins, not arteries. Specifically, the transverse and sigmoid sinuses, the large drainage channels that carry blood away from the brain and run right behind the ear, are the most frequent source. When these sinuses narrow (a condition called transverse sinus stenosis), blood squeezes through a tighter space, creating turbulence that the ear picks up as a whoosh. Transverse sinus stenosis is a treatable cause of both pulsatile tinnitus and elevated pressure inside the skull.2Annals of Vascular Surgery – Brief Reports and Innovations. Symptomatic transverse sinus stenosis. Clinical and angiographic classification and endovascular therapy: A case series
Another common venous cause involves a thinning or gap in the bone separating the sigmoid sinus from the middle ear. Normally a plate of bone acts as a sound barrier between the flowing blood and the ear. When that plate is dehiscent (partially missing), the sound of venous blood flow gets amplified dramatically. Biomechanical modeling has shown that a full gap in this bone raises the sound level at the eardrum by roughly 100 decibels compared to an intact plate, taking the venous hum from completely inaudible to clearly perceptible.3Journal of Biomechanics. Sigmoid sinus cortical plate dehiscence induces pulsatile tinnitus through amplifying sigmoid sinus venous sound That’s the difference between silence and a sound you can’t ignore.
A related finding is that sigmoid sinus wall anomalies (like diverticula or dehiscence) often exist alongside transverse sinus stenosis, and recent evidence suggests these wall abnormalities may actually be secondary to the stenosis upstream rather than independent problems. A study found that treating the stenosis alone with a stent resolved the whooshing even when the wall anomaly was left untouched.4Journal of NeuroInterventional Surgery. Outcomes of venous sinus stenosis stenting in patients with pulsatile tinnitus and sigmoid sinus wall anomalies This is encouraging because it means some patients may need only one procedure rather than multiple interventions.
Arterial Causes and Why They Need Urgent Attention
While venous causes are more common, arterial sources of pulsatile tinnitus tend to be more medically urgent. The list includes narrowing of the carotid artery from atherosclerosis, tears in the artery wall (dissection), fibromuscular dysplasia (an abnormal thickening of artery walls), aneurysms, and abnormally routed internal carotid arteries.5Journal of NeuroInterventional Surgery. Management of vascular causes of pulsatile tinnitus Turbulent blood flow through a narrowed or damaged carotid artery can produce a whooshing sound that travels to the nearby ear.6PubMed Central. Disappeared pulsatile tinnitus related to petrous segment stenosis of the ICA after relief of the stenosis by stenting
One arterial cause deserves special mention: the dural arteriovenous fistula (dAVF), an abnormal connection between an artery and a vein within the covering of the brain. In a study of 220 patients with dAVFs, about 14% first showed up to the doctor complaining only of pulsatile tinnitus and nothing else. When those patients were treated with embolization (a procedure that blocks the abnormal connection), pulsatile tinnitus disappeared completely in roughly 81% and improved substantially in another 12%.7Nature. Dural arteriovenous fistula masquerading as pulsatile tinnitus: radiologic assessment and clinical implications The concern with dAVFs is that some drain into veins that supply the brain itself, creating a risk of hemorrhage. Pulsatile tinnitus is sometimes the only warning sign, which is why the whooshing should never be dismissed without investigation.1PubMed Central.

Less Common Causes Worth Knowing About
Not every whooshing ear involves the big venous sinuses or the carotid artery. Several other conditions can produce a similar sound:
- Glomus tumors: These are small, slow-growing vascular tumors that can form in the middle ear (glomus tympanicum). Because they’re rich in blood vessels, they produce a pulsatile sound. In one series, pulsatile tinnitus was the main complaint in over 60% of patients, and surgical removal resolved the sound immediately in all of them.8PubMed Central. Treatment Outcomes of Patients with Glomus Tympanicum Tumors Presenting with Pulsatile Tinnitus
- Superior canal dehiscence: A gap in the bone over the superior semicircular canal (part of the inner ear balance system) can cause pulsatile tinnitus along with dizziness triggered by loud sounds or pressure changes.9PubMed Central. Superior Canal Dehiscence Syndrome: Lessons from the First 20 Years
- Jugular bulb anomalies: The jugular bulb sits right beneath the middle ear, and when it’s unusually high, large, or has a bony defect, it can transmit venous sounds directly to the ear.10PubMed Central. Endovascular treatment of pulsatile tinnitus associated with transverse sigmoid sinus aneurysms and jugular bulb anomalies
- Middle ear myoclonus: Tiny muscles in the middle ear (the tensor tympani and stapedius) can spasm rhythmically, producing sounds variously described as clicking, fluttering, or whooshing. This one is tricky because it can mimic vascular pulsatile tinnitus, though it often doesn’t sync perfectly with the heartbeat.11PubMed Central. Middle Ear Myoclonus: Two Informative Cases and a Systematic Discussion of Myogenic Tinnitus
Systemic factors can also amplify or trigger the sound. Anemia, hyperthyroidism, pregnancy, and high blood pressure all increase blood flow or change blood viscosity in ways that can make venous hum louder. In these cases, treating the underlying condition often quiets the whooshing without any ear-specific intervention.
Getting the Right Diagnosis
The single most important step in stopping the whooshing is getting imaging that can identify or rule out a vascular cause. A systematic review of imaging studies for pulsatile tinnitus found that the diagnostic yield varies enormously depending on what scan you get. CT angiography (CTA) was the highest-yield single test, identifying a cause in about 86% of cases. MRI combined with MR angiography found something in roughly 58% of cases. Carotid duplex ultrasound, which many primary care doctors order first, had the lowest yield at only about 21%. A multimodal approach combining more than one imaging type pushed results up to about 78%.12PubMed Central. Diagnostic Yield and Utility of Radiographic Imaging in the Evaluation of Pulsatile Tinnitus: A Systematic Review
Those numbers have real practical consequences. If your doctor orders only an ultrasound and it comes back clean, there’s roughly a four-in-five chance the cause was simply missed. If this happens to you, push for CTA or MRI/MRA. Both CT and MRI provide complementary information, and the choice of protocol can be tailored to what the doctor suspects.13PubMed Central. Pulsatile Tinnitus: Differential Diagnosis and Radiological Work-Up In some centers, a newer technique called 4D-CTA (essentially a time-resolved CT that captures blood flow dynamics) can detect vascular malformations that static imaging would miss.
A simple bedside clue: if pressing on the vein in your neck on the same side as the whooshing temporarily stops or changes the sound, that strongly points to a venous source. If the sound doesn’t change, an arterial cause is more likely. Your doctor may also listen with a stethoscope over your ear, behind your ear, and over your eye socket to hear turbulent flow.
Treatments That Can Stop the Sound
Treatment depends entirely on what’s causing the whooshing, which is why diagnosis comes first. But the good news is that for most identified causes, effective treatments exist.
Venous Sinus Stenting
For patients whose pulsatile tinnitus comes from transverse sinus stenosis, placing a small metal stent inside the narrowed sinus to hold it open has become an increasingly popular and effective option. A prospective trial of 42 patients found that 39 had complete resolution and 2 had near-complete resolution, with no serious complications.14PubMed Central. Venous sinus stenting for the treatment of isolated pulsatile tinnitus: Results of a prospective trial Another study of 29 patients reported that 28 had their tinnitus resolve on the same day as the procedure, with the median time to resolution being essentially zero days.15PLOS ONE. Resolution of Pulsatile Tinnitus after Venous Sinus Stenting in Patients with Idiopathic Intracranial Hypertension Reviews of published outcomes consistently report high resolution rates.16PubMed Central. Venous sinus stenting for intractable pulsatile tinnitus: A review of indications and outcomes
Stenting does require lifelong blood-thinning medication afterward, and there’s a small risk of stent-related complications, so it’s typically reserved for cases where the tinnitus is genuinely disabling and a clear stenosis has been confirmed on imaging. But for the right patient, the results can be dramatic.
Sigmoid Sinus Surgery
When the whooshing is caused by a defect or outpouching in the sigmoid sinus wall, surgeons can repair it through a procedure called sigmoid sinus resurfacing or reshaping, performed through the bone behind the ear (the mastoid). One study of 26 patients found that about 54% were completely cured and another 27% had major improvement, with average loudness scores dropping from about 5 out of 10 to just over 1.17PubMed Central. Surgical Outcomes of Sigmoid Sinus Resurfacing for Pulsatile Tinnitus: The Predictive Value of the Water Occlusion Test and Imaging Studies Long-term follow-up studies show that the improvement holds. Patients see a substantial decrease in their pulsatile tinnitus immediately after surgery, and that benefit is sustained or even continues to improve for at least a year, with no recurrence during extended follow-up.18Scientific Reports. Longitudinal analysis of surgical outcome in subjects with pulsatile tinnitus originating from the sigmoid sinus The transmastoid approach for repairing sigmoid sinus wall defects or diverticula is considered safe and effective.19Journal of Otology. Surgical treatment of pulsatile tinnitus related to the sigmoid sinus
Embolization for Arteriovenous Fistulas
For dAVFs, the standard treatment is transarterial embolization, where a catheter is threaded through blood vessels to the fistula and a material is injected to seal it off. As noted earlier, this resolves the tinnitus in the vast majority of patients.7Nature. Dural arteriovenous fistula masquerading as pulsatile tinnitus: radiologic assessment and clinical implications Case reports also confirm that when a dAVF causes both pulsatile tinnitus and hearing loss, embolization can recover both.20PubMed Central. Inner Ear Conductive Hearing Loss and Unilateral Pulsatile Tinnitus Associated with a Dural Arteriovenous Fistula
When No Vascular Cause Is Found
In a minority of cases, imaging comes back normal and no clear vascular or structural explanation emerges. This doesn’t mean the sound isn’t real; it often means the cause is too subtle for current imaging (a very mild venous turbulence, for instance, or a small anatomical variant below the threshold of detection). For these patients, the approach shifts to management rather than cure.
Cognitive behavioral therapy adapted for tinnitus doesn’t make the sound go away, but it can substantially reduce how much the sound bothers you. It works by identifying and restructuring the negative thought patterns and anxiety responses that the whooshing triggers, effectively turning down the brain’s alarm reaction to the noise.21PubMed Central. Cognitive behavioral therapy for tinnitus: evidence and efficacy Sound therapy, which uses low-level background noise to mask the pulsing, can also provide relief, especially at night when the whooshing tends to be most noticeable in a quiet room.
For some people, the whooshing gets louder or softer depending on jaw position, neck movement, or head posture. This suggests a somatosensory component, meaning the tinnitus is partly modulated by the musculoskeletal system. Research has found that patients with temporomandibular joint (TMJ) disorders who also have tinnitus often see consistent improvement in their tinnitus symptoms when their jaw condition is treated.22PubMed Central. Somatosensory tinnitus: Current evidence and future perspectives If your whooshing changes when you clench your jaw, turn your head, or press on your neck, it’s worth mentioning to your doctor since physical therapy or TMJ treatment may help.
What High-Grade Venous Stenosis Does Beyond the Ear
Pulsatile tinnitus from significant venous sinus stenosis isn’t just an annoying sound. When the stenosis is severe enough, it can affect how blood drains from the brain itself. Research comparing brain blood flow in patients with high-grade transverse sinus stenosis against healthy controls found that the patients had measurably reduced blood perfusion across the whole brain, with the difference most pronounced in gray matter. These patients also showed a higher incidence of subtle white matter changes on brain scans.23PubMed Central. Transverse Sinus Stenosis in Venous Pulsatile Tinnitus Patients May Lead to Brain Perfusion and White Matter Changes Patients with mild stenosis didn’t show these changes, suggesting the brain’s drainage has enough reserve to compensate up to a point. But for those with severe narrowing, the whooshing may be a signal that something more systemic deserves attention. This finding is one more reason to take the sound seriously and get it investigated rather than writing it off as a nuisance.
Practical Steps If You Have the Whooshing Right Now
If you’re hearing a rhythmic whoosh in your ear, here’s a reasonable path forward:
- Check the rhythm: Place two fingers on your neck to feel your pulse while listening to the sound. If they match, it’s very likely pulsatile tinnitus and not regular tinnitus or muscle spasm.
- Try neck compression: Gently press on the jugular vein on the same side as the sound (the side of your neck). If the sound stops or changes, you’re probably hearing venous flow. Release immediately and don’t hold pressure for more than a few seconds.
- See the right specialist: A general practitioner may not have the tools to investigate this. An otolaryngologist (ENT) or neurotologist experienced with pulsatile tinnitus is a better starting point. If imaging suggests a vascular cause, you may be referred to an interventional neuroradiologist or neurosurgeon.
- Ask for the right scan: If your doctor suggests starting with ultrasound alone, it’s reasonable to ask whether CTA or MRI/MRA can be included. The diagnostic yield is significantly higher with those modalities.
- Track the pattern: Note when the sound is worse (lying down, exercise, stress, certain head positions). This information helps your doctor narrow the differential and can point toward whether the source is venous, arterial, or musculoskeletal.
Middle Ear Myoclonus and the “Other Whoosh”
Not every rhythmic ear sound is vascular. Middle ear myoclonus produces sounds that can resemble pulsatile tinnitus but come from involuntary contractions of the tiny muscles inside the ear. People with this condition describe a wide variety of sounds including clicking, fluttering, buzzing, thumping, and occasionally whooshing or gushing.11PubMed Central. Middle Ear Myoclonus: Two Informative Cases and a Systematic Discussion of Myogenic Tinnitus The key distinction is that the rhythm of middle ear myoclonus doesn’t always line up with the heartbeat. The contractions can be irregular, faster than the pulse, or triggered by specific sounds.
Treatment for middle ear myoclonus is different from vascular pulsatile tinnitus. Muscle relaxants or anti-spasm medications sometimes help. In stubborn cases, the involved tendon can be surgically cut, though this is a last resort. If your “whooshing” has an irregular rhythm or happens in bursts rather than a steady pulse, make sure to mention that to your doctor since it changes the entire diagnostic direction.
