Pulsatile Tinnitus vs. Regular Tinnitus: What's the Difference?

Most people associate tinnitus with ringing in the ears.

But tinnitus doesn't always sound like ringing.

Some people describe a steady buzzing, hissing, or humming sound. Others report a rhythmic noise that resembles a heartbeat, a soft thumping, or a repeated whooshing sensation.

These differences are important because researchers recognize several forms of tinnitus with distinct characteristics and possible underlying mechanisms.

Two frequently discussed categories are pulsatile tinnitus and nonpulsatile tinnitus.

According to the National Institute on Deafness and Other Communication Disorders (NIDCD), tinnitus is the perception of sound without an external source. Most cases are subjective, meaning the sound is heard only by the individual experiencing it.

A smaller group of tinnitus experiences involve rhythmic sounds, sometimes synchronized with the heartbeat.

Researchers classify these experiences differently because they may involve different auditory, vascular, or mechanical processes.

This article explains the differences between pulsatile and nonpulsatile tinnitus, the terminology used in scientific literature, and what research has established about the possible origins of rhythmic ear sounds.

Research reviewed October 23, 2026.

What Is Pulsatile Tinnitus?

Pulsatile tinnitus is a form of tinnitus characterized by a rhythmic sound, often synchronized with a person's heartbeat.

People may describe the sound as:

• Whooshing
• Pulsing
• Thumping
• Beating
• Swishing
• Rhythmic humming

The American Speech-Language-Hearing Association (ASHA) describes pulsatile tinnitus as a rhythmic sound resembling the heartbeat.

A 2025 review published in the Journal of Clinical Medicine similarly identifies heartbeat-synchronous sound as a defining feature of typical pulsatile tinnitus.

However, not every rhythmic sound is necessarily synchronized with blood flow.

Scientific publications also describe pulse-asynchronous rhythmic sounds, sometimes associated with involuntary muscle activity.

The exact terminology varies somewhat among professional sources.

What Is Regular or Nonpulsatile Tinnitus?

The term regular tinnitus is commonly used in everyday language, but nonpulsatile tinnitus is the more precise scientific term.

Nonpulsatile tinnitus refers to tinnitus that does not characteristically follow a heartbeat-like rhythm.

It may sound like:

• Ringing
• Buzzing
• Hissing
• Whistling
• Humming
• Roaring
• High-pitched tones

Nonpulsatile tinnitus may be continuous or intermittent.

Its pitch and perceived loudness can vary.

According to the NIDCD, hearing loss and noise exposure are strongly associated with tinnitus.

Other recognized associations include certain medications, ear conditions, and head or neck injuries.

However, the sound itself does not identify a particular cause.

Pulsatile vs. Nonpulsatile Tinnitus: Main Differences

This table summarizes common classifications. It does not imply that the characteristics are exclusive or sufficient for diagnosis.

Sources: NIDCD, ASHA, and Pacheco-López et al. (2025).

How Common Is Pulsatile Tinnitus?

Pulsatile tinnitus is considerably less common than nonpulsatile tinnitus.

A comprehensive review published in June 2025 in the Journal of Clinical Medicine describes pulsatile tinnitus as representing approximately 5%–10% of tinnitus cases.

However, this figure should be interpreted as a literature-based estimate, rather than a precise percentage derived from a single representative population survey.

Reported proportions depend on:

• How pulsatile tinnitus is defined
• Whether the study includes pulse-asynchronous sounds
• The population being studied
• Whether participants come from specialist referral centers
• How tinnitus characteristics are recorded

The NIDCD estimates that tinnitus overall affects approximately 10%–25% of adults, but that broader estimate includes multiple tinnitus types.

It would be incorrect to use the overall tinnitus prevalence figure as the prevalence of pulsatile tinnitus.

Why Can Pulsatile Tinnitus Sound Like a Heartbeat?

The circulatory system continuously moves blood through arteries and veins.

Under certain conditions, blood flow or nearby anatomical structures may generate sounds that become perceptible.

A heartbeat-synchronous sound can arise when a person becomes aware of a sound associated with vascular activity.

Scientists describe several possible mechanisms, including altered blood-flow patterns, differences in vascular anatomy, and changes in how internally generated sound is transmitted.

However, hearing a heartbeat-like sound does not establish that a blood vessel abnormality is present.

The perceived sound may have different origins, and similar descriptions can occur in different conditions.

A 2024 review published in Current Pain and Headache Reports describes pulsatile tinnitus as an uncommon subtype involving a broad range of possible causes.

The researchers emphasize that vascular and nonvascular explanations must be distinguished.

What Does Research Say About the Possible Causes of Pulsatile Tinnitus?

Scientific reviews describe several categories of conditions associated with pulsatile tinnitus.

These are documented associations, not explanations that can be assigned to an individual based solely on how a sound is described.

1. Venous blood-flow conditions

Venous causes involve veins that carry blood back toward the heart.

Research discusses several structural or blood-flow-related findings, including:

• Venous sinus narrowing
• Certain differences in jugular bulb anatomy
• Sigmoid sinus wall abnormalities
• Other venous flow variations

These findings can alter how sound is generated or transmitted near the ear.

A 2025 review explains that venous abnormalities are an important group of potential causes in patients evaluated for pulsatile tinnitus.

However, identifying an anatomical variation does not necessarily prove that it causes a particular sound.

Source: Pacheco-López et al. (2025)

2. Arterial conditions

Arteries carry blood from the heart to the body's tissues.

Published reviews identify certain arterial abnormalities among the conditions associated with pulsatile tinnitus.

Examples include some forms of arterial narrowing and abnormal vascular connections.

One condition discussed in the literature is a dural arteriovenous fistula, an abnormal connection involving blood vessels near the protective coverings of the brain.

This is a recognized, potentially serious vascular condition.

However, its inclusion in research on pulsatile tinnitus does not mean it is a common explanation for every heartbeat-like ear sound.

American College of Radiology — Tinnitus Appropriateness Criteria (2023 Update)

Wang et al. (2024)

3. Idiopathic intracranial hypertension

Another condition discussed in pulsatile tinnitus literature is idiopathic intracranial hypertension (IIH).

This involves increased pressure around the brain without an identifiable structural cause such as a mass.

IIH can be associated with pulsatile tinnitus and other symptoms.

A 2025 review includes IIH among the conditions relevant to the differential diagnosis of pulsatile tinnitus.

However, heartbeat-like tinnitus alone does not establish that IIH is present.

Source: Pacheco-López et al. (2025)

4. Certain middle-ear conditions

Some sounds originate from structures within or near the middle ear.

Professional literature describes certain middle-ear masses, vascular anatomical differences, and mechanical processes among possible explanations.

These conditions are distinct from the more common auditory mechanisms associated with nonpulsatile tinnitus.

5. Systemic physiological conditions

Research has also discussed the relationship between pulsatile tinnitus and conditions that can affect blood circulation.

Examples include:

• Anemia
• Certain thyroid disorders
• Physiological states associated with increased cardiac output

These conditions may influence blood flow or its perception.

However, their presence does not establish a cause-and-effect relationship with a particular tinnitus experience.

Is Every Rhythmic Ear Sound Caused by Blood Flow?

No.

This is an important distinction in modern tinnitus research.

Not all rhythmic sounds are synchronized with the heartbeat.

Some repetitive sounds are associated with mechanical activity involving muscles near the ear.

For example, scientific literature describes involuntary muscle contractions involving the middle ear or palate.

These may produce clicking or repetitive sounds.

The 2026 updated American Academy of Otolaryngology–Head and Neck Surgery Foundation tinnitus guideline distinguishes:

• Pulse-synchronous tinnitus: Rhythmic sound occurring in time with the heartbeat, often associated with vascular mechanisms.
• Pulse-asynchronous rhythmic tinnitus: Rhythmic sound not matching the heartbeat, potentially involving mechanical processes such as middle-ear or palatal muscle activity.

This distinction explains why rhythmic tinnitus and heartbeat-synchronous tinnitus are related terms but not always interchangeable.

Source: AAO-HNSF — Executive Summary of the Clinical Practice Guideline: Tinnitus Update (2026)

Is Pulsatile Tinnitus the Same as Objective Tinnitus?

No.

These terms describe different characteristics.

Pulsatile tinnitus refers to the rhythmic quality of the perceived sound.

Objective tinnitus is a term historically used when a sound generated within the body can also be detected by an examiner.

By contrast, subjective tinnitus refers to sound perceived only by the person experiencing it.

Some pulsatile tinnitus is objective, but not all pulsatile tinnitus can be heard by another person.

Likewise, certain objectively detectable internal sounds may arise from muscle activity rather than blood flow.

A 2025 scientific review also notes that some researchers increasingly use the term somatosound for sounds generated by identifiable bodily structures.

The terminology continues to evolve.

ASHA — Tinnitus and Hyperacusis

Pacheco-López et al. (2025)

Can Pulsatile Tinnitus Occur in Only One Ear?

Yes.

Pulsatile tinnitus can be perceived in one ear or both ears.

Clinical research often distinguishes between unilateral and bilateral tinnitus.

• Unilateral means the sound is perceived on one side.
• Bilateral means the sound is perceived on both sides.

This distinction is important in medical research because the possible underlying conditions and anatomical findings may differ.

However, neither the affected side nor the number of ears involved can establish a diagnosis.

Nonpulsatile tinnitus can also be unilateral or bilateral.

Source: AAO-HNS — Evaluation and Management of Pulsatile Tinnitus (2024)

Why Is Pulsatile Tinnitus Considered Different in Clinical Research?

Although both forms of tinnitus involve a perceived sound, medical literature distinguishes them partly because of their different associations.

Nonpulsatile tinnitus is frequently studied in relation to hearing loss, cochlear changes, and neural auditory processing.

Pulsatile tinnitus is more often studied in relation to vascular, anatomical, and mechanical factors.

Some of the conditions associated with pulsatile tinnitus can have significant medical implications.

This is why professional guidelines treat heartbeat-synchronous tinnitus as a distinct finding rather than assuming it has the same origin as common nonpulsatile ringing.

The U.S. National Institute on Deafness and Other Communication Disorders acknowledges that some pulsatile tinnitus involves identifiable bodily sound sources.

The American College of Radiology's clinical guidance also distinguishes pulsatile from nonpulsatile tinnitus when discussing the use of medical imaging.

These are descriptions of established clinical literature, not a means of determining the cause of an individual's symptoms.

What Does the October 2026 Research Say About Pulsatile Tinnitus?

On October 9, 2026, researchers published an evidence-based expert consensus in the European Journal of Radiology.

The publication was titled:

Clinical Practice Guidance for Imaging Selection in Pulsatile Tinnitus: An Evidence-Based Expert Consensus

The authors included specialists in radiology and medical imaging from institutions in China.

The review focused on the different vascular and nonvascular abnormalities associated with pulsatile tinnitus and the challenges of studying them.

What did the researchers emphasize?

The consensus identified several important points.

First: Pulsatile tinnitus is associated with a broad spectrum of possible underlying conditions.

Second: Different anatomical findings may require different imaging techniques to be identified in research and clinical settings.

Third: No single imaging technique provides equally useful information for every possible condition.

Fourth: Published diagnostic evidence varies in quality, and some recommendations rely on expert consensus rather than direct comparisons from high-quality clinical studies.

Did the paper report a high rate of identifiable abnormalities?

Yes.

The authors described literature indicating that targeted radiological imaging can identify an underlying abnormality in more than 75% of certain evaluated pulsatile tinnitus cases.

However, that figure should not be interpreted as meaning 75% of everyone who notices a rhythmic ear sound has a dangerous condition.

It reflects findings from selected populations and research settings.

The diagnostic yield can vary substantially depending on participant selection, examination methods, and the imaging techniques used.

What Did Earlier Imaging Research Establish?

The American College of Radiology published an update to its tinnitus imaging criteria in 2023.

That publication emphasized the distinction between pulsatile and nonpulsatile tinnitus.

For pulsatile tinnitus, it identified several categories of potential findings, including:

• Arterial abnormalities
• Venous abnormalities
• Middle-ear vascular lesions
• Certain skull-base anatomical differences

The review also described why observations involving the middle ear can influence which anatomical structures are examined.

In contrast, nonpulsatile tinnitus without additional relevant findings is treated differently in published imaging guidance.

The ACR's recommendations demonstrate that tinnitus classification matters scientifically and clinically.

However, these recommendations are written for healthcare professionals; they do not permit readers to select or interpret investigations based solely on an online description of sound.

Does Pulsatile Tinnitus Always Mean Something Serious?

No.

Published literature describes a wide range of associations, from relatively common anatomical or physiological variations to less common conditions with greater medical significance.

The term pulsatile does not identify a specific disorder.

It simply characterizes how the sound is perceived.

At the same time, pulsatile tinnitus should not be assumed to have exactly the same background mechanisms as ordinary nonpulsatile ringing.

Professional guidelines distinguish it because certain underlying conditions can be identified and some are medically significant.

The scientifically accurate conclusion is that the sound's rhythmic character is an important classification, but it cannot establish the underlying cause or seriousness on its own.

Sources: ASHA and Pacheco-López et al. (2025).

How Is Pulsatile Tinnitus Different From Tinnitus That Changes With Head or Jaw Movement?

Tinnitus research recognizes another phenomenon called somatosensory tinnitus.

The NIDCD explains that some people notice changes in tinnitus when moving the head, neck, eyes, or jaw, or when certain parts of the body are touched.

This is often discussed in relation to sensory input from the musculoskeletal system.

However, movement-related changes are not the same defining feature as a heartbeat-like rhythm.

The terms describe different characteristics:

These categories are not necessarily mutually exclusive.

They also do not establish individual medical causes.

Sources: NIDCD — Tinnitus and ASHA — Tinnitus and Hyperacusis.

What Questions Remain Unanswered in Pulsatile Tinnitus Research?

Despite advances in medical imaging and understanding of auditory perception, researchers continue to investigate several issues.

How common is pulsatile tinnitus in the general population?

Estimates vary, and many published studies involve selected clinical populations rather than nationally representative samples.

Which anatomical findings are genuinely responsible for a perceived sound?

A visible vascular or structural variation does not necessarily establish that it causes tinnitus.

Why do some people notice internal bodily sounds while others do not?

Scientists are investigating anatomical, auditory, and perceptual factors that may influence awareness of internally generated sounds.

What is the most reliable terminology?

Researchers continue to discuss distinctions among pulsatile tinnitus, rhythmic tinnitus, objective tinnitus, and somatosounds.

How reliable are published diagnostic-yield estimates?

Reported yields vary substantially according to study population and the techniques used.

Can one explanation account for every case?

No. Current research supports a diverse range of possible mechanisms rather than one universal explanation.

Frequently Asked Questions About Pulsatile Tinnitus

What is the difference between pulsatile tinnitus and regular tinnitus?

Pulsatile tinnitus involves a rhythmic sound, commonly synchronized with the heartbeat. Nonpulsatile tinnitus is more often described as ringing, buzzing, or hissing without a heartbeat-like pattern.

What does pulsatile tinnitus sound like?

Descriptions commonly include whooshing, swishing, beating, and throbbing sounds. The exact perception varies between individuals.

Is a whooshing sound always pulsatile tinnitus?

No. The word whooshing describes sound quality, not a specific diagnosis. The timing and other characteristics are important distinctions in scientific definitions.

Does pulsatile tinnitus always follow the heartbeat?

Typical pulse-synchronous tinnitus does. However, some professional literature also discusses rhythmic pulse-asynchronous tinnitus associated with mechanical processes.

Is pulsatile tinnitus rare?

It is less common than nonpulsatile tinnitus. A 2025 scientific review describes it as accounting for approximately 5%–10% of tinnitus cases, although the estimate varies with definitions and populations.

Is pulsatile tinnitus caused by blood vessels?

Vascular conditions are important recognized associations, but not every rhythmic sound has a vascular cause. Nonvascular and mechanical processes are also documented.

Can pulsatile tinnitus happen in just one ear?

Yes. It can be perceived in one ear or both ears.

Can someone else hear pulsatile tinnitus?

In some cases, an examiner may detect an internally generated sound. This is historically described as objective tinnitus. However, not every pulsatile tinnitus sound is externally detectable.

Is pulsatile tinnitus the same as objective tinnitus?

No. Pulsatile describes rhythm, while objective refers to whether another person can detect the sound. The classifications can overlap but are not identical.

Is ringing in the ears always nonpulsatile tinnitus?

Ringing is most commonly associated with nonpulsatile tinnitus, but sound descriptions are subjective and do not independently define a physiological cause.

Can a clicking sound be pulsatile tinnitus?

Some rhythmic clicking sounds may be associated with mechanical activity, such as involuntary middle-ear or palatal muscle contractions. These may not be synchronized with the heartbeat.

Is pulsatile tinnitus always permanent?

No single course applies to every case. The outcome depends on underlying factors, which vary considerably.

Does pulsatile tinnitus always mean a serious condition?

No. However, professional literature recognizes both less serious and potentially significant medical associations. The sound's rhythm alone does not determine which applies.

Why do researchers use different imaging methods for pulsatile tinnitus?

Different imaging techniques reveal different anatomical structures. A 2026 expert consensus explains that the scientific and clinical questions vary depending on the suspected mechanism.

Does having normal hearing rule out pulsatile tinnitus?

No. Tinnitus classification is not determined by hearing thresholds alone, and some forms of pulsatile tinnitus involve mechanisms outside the cochlear sensory structures.

Final Thoughts: Why the Distinction Matters

Tinnitus is not one uniform sound or experience.

Nonpulsatile tinnitus is the more common form and is frequently associated with hearing loss and auditory processing mechanisms.

Pulsatile tinnitus is less common and is characterized by rhythmic sounds, often corresponding to the heartbeat.

Research associates pulsatile tinnitus with several possible vascular, anatomical, and mechanical processes.

However, the presence of a pulse-like sound does not establish any single cause.

The October 2026 expert consensus adds to a growing body of evidence showing that pulsatile tinnitus requires careful classification in scientific research because different underlying mechanisms may produce similar sound descriptions.

The central distinction is simple: tinnitus that follows a rhythm is not necessarily the same phenomenon as a continuous ringing or buzzing sound.

Understanding that difference provides a more accurate foundation for interpreting hearing-health terminology and published research.
