Understanding Tinnitus: what it is, why it happens,
and when to seek help
Ringing, buzzing, hissing, or clicking that no one else can hear can be unsettling — but it's more common than you think, and understanding it is the first step toward feeling in control of it.
A phantom sound, not a diagnosis in itself
Tinnitus is the perception of sound — ringing, buzzing, hissing, roaring, clicking, or humming — when there's no actual external sound producing it. It's sometimes called a “phantom” sound because the ear and brain are generating the perception on their own, without any matching sound wave in the room. Tinnitus is a symptom, not a disease — it's a signal that something else is happening somewhere along the hearing system, the way a headache signals something without being a diagnosis on its own.
The brain often keeps the sound going — even after the ear settles down
Sound normally travels a clear path from your outer ear to your brain. Tinnitus can originate anywhere along that path, and often involves more than one point.
When the brain receives less input from the ear — often from hearing loss — it can “turn up” its own internal activity to compensate, a process researchers call central gain. This is part of why cutting the hearing nerve doesn't reliably stop tinnitus: once the brain has adapted, it can keep generating the perception on its own.
Tinnitus also frequently engages brain regions that have nothing to do with hearing on the surface — particularly the areas responsible for emotion, attention, and the stress response. This is why two people with very similar hearing loss can experience tinnitus completely differently: one may barely notice it, while the other finds it distressing. The difference often comes down to how the brain's emotional and attention networks are engaging with the sound, not the sound itself.
What can trigger or worsen tinnitus
Tinnitus is highly individual — researchers have identified several factors that most commonly play a role.
Hearing Loss
The single biggest risk factor. When the inner ear loses certain frequencies, the brain may generate its own activity there — perceived as tinnitus.
Noise Exposure
Loud noise — a single intense event or years of repeated exposure — can damage the inner ear's hair cells. One of the most preventable causes.
Head & Neck Injury
Whiplash, concussion, and other trauma can affect nerves and structures tied to hearing — sometimes without direct damage to the ear.
Medical Conditions
Earwax buildup, ear infections, otosclerosis, Ménière's disease, TMJ disorders, and vascular conditions can all contribute to tinnitus.
Medications
Several hundred prescription and OTC medications list tinnitus as a possible side effect. It often improves once the medication is adjusted.
Stress
Stress activates the body's fight-or-flight response, heightening nervous system sensitivity and often making existing tinnitus feel louder.
For roughly 40% of people, a single clear cause is never pinpointed — that doesn't make the tinnitus any less real, it simply reflects how complex the underlying mechanisms can be.
Tinnitus isn't one condition — it's several
Audiologists classify tinnitus in a few different ways. Understanding which type you have helps guide what kind of evaluation makes sense next.
Subjective vs. Objective Most Common
Subjective tinnitus is heard only by the patient — this accounts for the vast majority of cases.
Objective tinnitus is rare and can actually be heard by an examiner, sometimes with a stethoscope, because it's caused by a physical, measurable sound source in the body, such as blood flow or muscle spasms near the middle ear.
Primary vs. Secondary
Primary tinnitus has no clearly identifiable cause other than hearing loss, or no obvious cause at all.
Secondary tinnitus is linked to a specific, identifiable condition — such as earwax blockage, a middle ear disorder, TMJ dysfunction, or a vascular abnormality. Because it often has a treatable root cause, identifying it matters.
Pulsatile Tinnitus Needs Prompt Care
A distinct pattern where the sound rises and falls in rhythm with your heartbeat or pulse. It's usually related to blood flow near the ear and can stem from a variety of vascular causes.
Because it can occasionally signal something that needs prompt medical attention, pulsatile tinnitus is one of the “red flag” symptoms below.
Somatic (Somatosensory) Tinnitus
Influenced by the musculoskeletal system rather than originating purely in the ear — most often connected to the jaw joint (TMJ), neck muscles, or head and neck injuries.
People with this type often notice their tinnitus changes when they clench their jaw, turn their head, or press on certain muscles. Hearing tests are frequently normal.
Acute vs. Chronic
Acute tinnitus has been present for less than six months and has a higher chance of resolving on its own, especially when linked to a temporary cause like noise exposure or medication.
Chronic tinnitus has persisted for six months or longer. It's less likely to disappear entirely, but many people find it becomes far less noticeable over time — and an accurate hearing evaluation is a good place to start understanding your options.
Not all tinnitus affects people the same way — and that's good news
Most people who experience tinnitus are not significantly bothered by it once they understand what it is. A smaller group benefits from active management, and only a small fraction find it truly debilitating.
Most tinnitus isn't an emergency — but a few signs mean it's time to be seen
Please schedule an appointment, or seek urgent medical care, if your tinnitus comes with any of the following:
Tinnitus that pulses in rhythm with your heartbeat
Tinnitus in only one ear, or noticeably different between ears
Sudden or one-sided hearing loss
Dizziness or vertigo along with the tinnitus
Facial numbness or other neurological symptoms
Tinnitus that began after a head or neck injury
Noticeable impact on sleep, concentration, or mood
Tinnitus that hasn't improved despite initial self-care
Even without these signs, if your tinnitus is new, persistent, or bothersome, a full audiologic evaluation is worthwhile — it helps rule out treatable causes and gives you a clear picture of your hearing.
