Tinnitus Causes and Symptoms: Understanding Ringing in the Ears

What Is Tinnitus?

Tinnitus is the perception of sound without any actual external sound present. It represents a symptom of an underlying condition rather than a single disease. According to the National Institute on Deafness and Other Communication Disorders (NIDCD), tinnitus affects millions of Americans, with prevalence increasing with age.¹

The condition can affect one or both ears and may present as constant or intermittent phantom sounds. Most people who experience tinnitus have some degree of hearing loss, though the causes are not always clear. Tinnitus is also the most common service-related disability among veterans, particularly those exposed to loud noise during military service.²

Research shows that tinnitus usually results from a disorder of the auditory system, typically in the peripheral structures like the inner ear, though it can occasionally originate from central nervous system issues. Recent studies have also identified that reduced functioning in the cochlear nerve may lead to increased brain activity that generates these phantom sounds, even in people with normal hearing tests.³

What Does Tinnitus Sound Like?

The sounds of tinnitus vary significantly from person to person. Common descriptions include:

• Ringing

• Buzzing in ears

• Clicking

• Hissing

• Roaring

• Whooshing

The intensity can range from soft background noise to loud sounds that interfere with concentration and daily activities. Some people experience tinnitus in only one ear, while others hear it in both ears or perceive it as coming from inside the head. The noise may be continuous or intermittent, and in some cases, it may synchronize with the heartbeat, a specific type called pulsatile tinnitus.

Common Causes of Tinnitus

Multiple factors can trigger or contribute to tinnitus:

Age-Related Hearing Loss: As people age, the sensory cells in the inner ear naturally deteriorate, which can lead to both hearing loss and tinnitus. This condition, known as presbycusis, is one of the most common causes of tinnitus in older adults.

Noise Exposure: Extended exposure to loud noise can result in continuous damage to hair cells in the inner ear and degeneration of spiral ganglion neurons. Many people experience tinnitus after exposure to loud noise in workplace settings or at sporting events and concerts. This damage can gradually decrease speech recognition and increase hearing thresholds, potentially leading to permanent hearing loss.²

Earwax Blockage: When earwax accumulates and becomes too hard to wash away naturally, it can cause hearing loss or irritation of the eardrum, both of which may trigger tinnitus.

Ear Infections: Infections that cause inflammation in the ear structures can temporarily produce tinnitus symptoms until the infection resolves.

Head or Neck Injuries: Trauma to the head or neck can affect the inner ear, hearing nerves, or the brain's auditory processing centers, sometimes resulting in tinnitus. The condition can also arise from somatosensory system disorders affecting the head and neck.⁴

Ototoxic Medications: Certain medications are associated with tinnitus, including non-steroidal anti-inflammatory drugs like ibuprofen, naproxen, and aspirin, certain antibiotics, anti-cancer drugs, anti-malaria medications, and some antidepressants. The risk often increases with higher doses.²

Medical Conditions That Cause Tinnitus

Several medical conditions can manifest tinnitus as a symptom:

Meniere's Disease: This inner ear disorder causes symptoms including hearing loss, vertigo, tinnitus, and a feeling of pressure in the ear. Meniere's disease is characterized by spontaneous vertigo attacks lasting 20 minutes to 12 hours, along with documented low- to mid-frequency sensorineural hearing loss and fluctuating aural symptoms.⁵

TMJ Disorders: Problems with the temporomandibular joint, which connects your jaw to your skull, can cause or worsen tinnitus due to the proximity of these structures to the ear.

Blood Vessel Disorders: Conditions affecting blood flow can cause a specific type of tinnitus called pulsatile tinnitus. These include aneurysms, arteriovenous malformations, twisted arteries, or benign blood vessel tumors behind the eardrum.⁶

Acoustic Neuroma: Also called vestibular schwannoma, this benign tumor grows on the nerve connecting the inner ear to the brain. Unilateral hearing loss plus tinnitus should increase suspicion for acoustic neuroma.⁷

High Blood Pressure and Hypertension: Research published in 2026 found that high blood pressure can impair hearing, cause tinnitus, and trigger dizziness. The study showed that blood pressure decrease is associated with improvements in these symptoms.⁸ Metabolic diseases such as heart disease, hypertension, and diabetes are all associated with the onset of tinnitus.²

Other Conditions: Chronic stress can worsen tinnitus perception, as stress and anxiety may amplify the brain's response to these phantom sounds.

Types of Tinnitus

Understanding the type of tinnitus can help healthcare providers determine the underlying cause:

Subjective Tinnitus: This is the most common form, accounting for the vast majority of cases. Only the person experiencing it can hear the sounds. It may result from auditory pathway problems in the outer, middle, or inner ear, or from issues with auditory processing in the brain.

Objective Tinnitus: This rare type can be heard by a doctor during an examination, usually through a stethoscope. It typically results from blood vessel problems, muscle contractions, or inner ear bone conditions.

Pulsatile Tinnitus: This distinct type creates a thumping or swooshing noise that keeps time with your heartbeat. The difference between pulsatile tinnitus and regular tinnitus is that pulsatile tinnitus creates rhythmic sounds that sync with your pulse, while regular tinnitus makes constant random noise.⁶

Pulsatile tinnitus may be the first sign of a serious medical condition affecting blood flow. A variety of vascular malformations and disorders can be the source, making it important to seek medical evaluation promptly.⁶

When to See a Doctor for Tinnitus

While occasional brief episodes of tinnitus are common and usually not concerning, certain warning signs warrant medical evaluation:

Seek prompt medical attention if you experience:

• Sudden onset of tinnitus, especially without an obvious cause

• Tinnitus in only one ear (unilateral tinnitus)

• Pulsatile tinnitus that synchronizes with your heartbeat

• Tinnitus accompanied by hearing loss, dizziness, or vertigo

• Tinnitus that significantly affects your quality of life, sleep, or concentration

Patients with unilateral tinnitus, pulsatile tinnitus, or tinnitus associated with vertigo should undergo thorough assessment, including a complete medical history, physical examination, and audiologic testing.⁶ If asymmetric hearing loss is found during testing, MRI imaging of the internal auditory canal may be necessary to rule out conditions like vestibular schwannoma.⁷

Conclusion

Tinnitus is a common symptom experienced by millions of people, characterized by the perception of sounds like ringing, buzzing, or hissing when no external sound is present. While it often results from benign causes like age-related hearing loss or temporary noise exposure, it can sometimes indicate underlying medical conditions requiring treatment. Understanding the various causes, recognizing different types of tinnitus, and knowing when to seek medical evaluation can help individuals manage this condition more effectively.
