Definition and Overview
Tinnitus, commonly described as "ringing in the ears," is the perception of sound when no external sound source is present. This phantom noise can manifest as ringing, buzzing, roaring, clicking, hissing, or humming sounds. While often called a condition itself, tinnitus is actually a symptom of an underlying issue affecting the auditory system, which includes the ear, auditory nerve, and brain areas that process sound.
Tinnitus affects approximately 15-20% of people and is especially common in older adults. It can be temporary, lasting minutes to hours, or chronic, persisting for months or years. The sound may be heard in one ear (unilateral), both ears (bilateral), or seem to come from inside the head. The volume can range from a barely noticeable background sound to a loud noise that interferes with concentration and daily activities.
There are two main types of tinnitus: subjective tinnitus, which only you can hear and accounts for over 99% of cases, and objective tinnitus, a rare form that your doctor can also hear during examination. Understanding the nature, triggers, and impact of your tinnitus is crucial for finding effective management strategies.
Common Causes
Hearing-Related Causes
- Age-related hearing loss: Most common in over 60s
- Sensorineural hearing loss: Inner ear damage
- Conductive hearing loss: Middle ear problems
- Noise-induced hearing loss: Loud noise exposure
- Eardrum damage: Perforation or scarring
- Acoustic trauma: Sudden loud sounds
- Ototoxic medications: Aspirin, antibiotics
Ear Conditions
- Ear wax blockage: Common reversible cause
- Outer ear infection: Swimmer's ear
- Middle ear infection: Fluid buildup
- Eustachian tube dysfunction: Pressure problems
- Meniere's disease: Inner ear disorder
- Otosclerosis: Bone growth in ear
- Acoustic neuroma: Benign tumor
Other Causes
- Idiopathic tinnitus: No identifiable cause
- TMJ disorders: Jaw joint problems
- Head or neck injuries: Trauma effects
- Blood vessel disorders: Pulsatile tinnitus
- High blood pressure: Vascular changes
- Stress and anxiety: Can trigger or worsen
- Muscle spasms: In middle ear
- Certain medications: Side effects

When to Seek Medical Attention
Consult a healthcare provider if you experience:
- Sudden onset tinnitus in one ear
- Tinnitus with sudden hearing loss
- Pulsatile tinnitus (heartbeat sounds)

- Tinnitus affecting only one ear
Diagnostic Approach
Healthcare providers evaluate tinnitus through:
Diagnostic Methods
- Medical history: Onset, triggers, medications
- Physical examination: Ears, head, neck
- Hearing tests: Audiometry evaluation
- Tympanometry: Middle ear function
- Imaging studies: MRI or CT if needed
- Blood tests: Thyroid, anemia, vitamins
- Tinnitus matching: Identify pitch and volume
- Movement tests: Jaw, neck, eyes
Treatment and Management
Sound Therapies
- White noise machines
- Masking devices
- Hearing aids if hearing loss
- Tinnitus retraining therapy (TRT)
- Notched music therapy
- Background music or nature sounds
- Sound apps for smartphones
- Combination devices
Medical Treatments
- Ear wax removal
- Treating ear infections
- Changing ototoxic medications
- Blood pressure management
- TMJ treatment
- Cognitive behavioral therapy (CBT)
- Antidepressants or anti-anxiety meds
- Experimental treatments (research trials)
Coping and Prevention
Manage tinnitus and prevent worsening:
- Protect hearing: Use earplugs in loud environments
- Reduce volume: Keep music/TV at safe levels
- Manage stress: Relaxation techniques, meditation
- Improve sleep: Regular schedule, sound machine
- Exercise regularly: Improves blood flow
- Limit triggers: Caffeine, alcohol, nicotine
- Join support groups: Connect with others
- Stay occupied: Distraction helps
- Avoid silence: Low background noise
- Track patterns: Identify personal triggers
