Tinnitus (Ringing in Ears)

Tinnitus is the perception of sound when no external sound is present. Most commonly described as ringing, but can also sound like buzzing, hissing, whistling, swooshing, or clicking. It's a symptom, not a disease itself. **Key Facts:** - **Not a disease:** Tinnitus is a symptom of an underlying condition - **Very common:** Affects 15-20% of people - **Types:** Subjective (only you hear it) vs Objective (doctor can hear it too — rare) - **Causes:** [Hearing loss](/condition/hearing-loss), noise exposure, aging, medications - **No cure:** But many treatments help manage it **Types of Tinnitus:** - **Subjective:** Only you can hear it (99% of cases) - **Objective:** Doctor can hear it too (rare — usually vascular or muscular) - **Pulsatile:** Rhythmic, often matching heartbeat (needs evaluation) **How It Differs from [Hearing Loss](/condition/hearing-loss):** - **Tinnitus:** Perception of sound that isn't there - **[Hearing loss](/condition/hearing-loss):** Difficulty hearing external sounds - Often occur together (90% of tinnitus patients have hearing loss) - See our [tinnitus vs hearing loss comparison](/compare/tinnitus-vs-hearing-loss) **Related Conditions:** - [Hearing loss](/condition/hearing-loss) — most common cause - [Ear infection](/condition/ear-infection) — can cause temporary tinnitus - [Meniere's disease](/condition/menieres-disease) — tinnitus with vertigo - [TMJ disorders](/condition/tmj) — jaw problems can cause tinnitus - [Anxiety](/condition/anxiety) and [depression](/condition/depression) — often co-occur - [High blood pressure](/condition/high-blood-pressure) — pulsatile tinnitus **Warning Signs:** Sudden tinnitus in one ear only, pulsatile tinnitus, or tinnitus with hearing loss/dizziness needs medical evaluation.

**How Tinnitus Develops:** **The Normal Hearing Process:** Sound waves enter your ear, causing the eardrum and tiny hair cells in the inner ear (cochlea) to vibrate. These hair cells convert vibrations into electrical signals sent to your brain. **1. Hair Cell Damage:** The most common cause. When inner ear hair cells are damaged (from noise, aging, or other causes), they may send random electrical signals to the brain, perceived as tinnitus. **2. Brain Compensation:** When [hearing loss](/condition/hearing-loss) occurs, the brain may "turn up the volume" trying to hear better. This can amplify neural activity perceived as tinnitus. **3. Neural Changes:** Damaged auditory pathways can lead to abnormal neural activity in the auditory cortex, creating phantom sounds. **Common Triggers:** - **Loud noise exposure:** Concerts, machinery, headphones at high volume - **Aging:** [Hearing loss](/condition/hearing-loss) from aging (presbycusis) - **Earwax:** Blockage can cause temporary tinnitus - **Medications:** Aspirin (high doses), certain antibiotics, diuretics, some cancer drugs - **Health conditions:** [High blood pressure](/condition/high-blood-pressure), cardiovascular disease, [diabetes](/condition/type-2-diabetes) - **Stress:** [Anxiety](/condition/anxiety) and [stress](/condition/stress) can worsen tinnitus **Pulsatile Tinnitus:** When you hear a rhythmic sound matching your heartbeat, this may indicate blood vessel problems and should be evaluated.

**No FDA-Approved Drug Cures Tinnitus** Treatment focuses on reducing impact and managing symptoms. **Sound Therapy:** - **Masking:** Background sound to cover tinnitus - **Habituation:** Train brain to ignore tinnitus (Tinnitus Retraining Therapy) - **Hearing aids:** Amplify external sounds, reducing tinnitus perception **Cognitive Behavioral Therapy (CBT):** - Most evidence-based psychological treatment - Doesn't eliminate tinnitus but reduces distress - Changes negative thought patterns - Improves coping strategies **Tinnitus Retraining Therapy (TRT):** - Combines counseling with sound therapy - Aims for habituation (brain learns to ignore tinnitus) - Takes 12-24 months for full effect **Hearing Aids:** - For those with [hearing loss](/condition/hearing-loss) - Amplifying external sounds reduces tinnitus prominence - Many hearing aids have built-in tinnitus maskers **Medications:** - No medication specifically treats tinnitus - Antidepressants may help associated [anxiety](/condition/anxiety)/[depression](/condition/depression) - Treat underlying conditions **Address Underlying Causes:** - Remove earwax if blocked - Treat [ear infections](/condition/ear-infection) - Manage [blood pressure](/condition/high-blood-pressure) - Review medications with doctor - Evaluate for [Meniere's disease](/condition/menieres-disease) or acoustic neuroma if indicated **Complementary Approaches:** - Acupuncture (limited evidence) - Supplements like ginkgo (studies inconclusive) - Stress management
