Persistent Tinnitus: Understanding the Noise Only You Can Hear

High-pitched ringing, a low buzzing sound, a cricket-like noise or a whooshing sound... persistent tinnitus affects approximately 10 to 15% of the adult population, with forms ranging from mild and intermittent discomfort to a severe condition that can have a lasting impact on quality of life. Understanding its causes is the first step toward managing it better.

What Is Persistent Tinnitus?

Persistent tinnitus is the perception of a sound in the absence of an external sound source. It is not a disease in itself, but rather a symptom indicating dysfunction somewhere along the auditory pathway: the outer ear, middle ear, inner ear, auditory nerve, or the brain's neural pathways involved in sound processing.

The Two Types of Tinnitus

• Subjective tinnitus (99% of cases): heard only by the affected person, linked to abnormal activity within the auditory system.
• Objective tinnitus (rare): caused by an actual sound produced inside the body (turbulent blood flow, muscle contractions) and sometimes audible to the doctor during examination.

Common Causes of Persistent Tinnitus

1. Noise-Induced Hearing Loss

Repeated exposure to loud sounds (concerts, listening to headphones at high volume, noisy work environments) damages the hair cells in the inner ear, causing both hearing loss and tinnitus. This is the most common cause among young adults.

2. Presbycusis (Age-Related Hearing Loss)

The natural aging of the inner ear is frequently accompanied by tinnitus, generally affecting both ears and producing a high-pitched tone.

3. Earwax Blockage

A simple and common cause that is easily treatable: the accumulation of earwax in the ear canal can cause tinnitus, which may disappear after professional cleaning.

4. High Blood Pressure

High blood pressure can cause pulsatile tinnitus, synchronized with the heartbeat, due to increased blood flow near the ear.

5. Stress and Anxiety

Chronic stress is generally not a direct cause of tinnitus, but it can significantly amplify its perception and discomfort. A vicious cycle often develops: tinnitus generates stress, which in turn intensifies the perception of tinnitus.

6. Certain Medications (Ototoxicity)

Certain antibiotics (aminoglycosides), high doses of aspirin, some diuretics and chemotherapy drugs can cause tinnitus, generally reversible after stopping the treatment.

7. Temporomandibular Joint (TMJ) Disorders

Jaw dysfunctions (bruxism, dental malocclusion) can cause tinnitus due to the anatomical proximity of the jaw to the ear.

8. Ménière's Disease

An inner ear disorder associated with tinnitus, spinning vertigo, fluctuating hearing loss and a feeling of fullness in the ear, occurring in episodes.

9. Acoustic Neuroma

A rare benign tumor of the auditory nerve, generally associated with persistent unilateral tinnitus and progressive hearing loss in one ear — an MRI is required to rule out this cause.

When Should Persistent Tinnitus Be a Cause for Concern?

• Persistent unilateral tinnitus (in one ear)
• Pulsatile tinnitus (synchronized with the pulse)
• Associated hearing loss, even if mild
• Associated dizziness or vertigo
• Sudden onset following head trauma
• Tinnitus appearing after taking a new medication

Medical Assessment of Persistent Tinnitus

• Otoscopy: checking for earwax blockage or abnormalities of the eardrum.
• Audiometry: accurately measuring hearing across all frequencies.
• Cardiovascular assessment: checking blood pressure in cases of pulsatile tinnitus.
• Brain MRI: in cases of persistent unilateral tinnitus to rule out a tumor-related cause.

Available Solutions and Treatments

Treating the Underlying Cause

Removal of an earwax blockage, controlling blood pressure, stopping an ototoxic medication, treating a TMJ disorder: the first step is always to treat the identified underlying cause when one exists.

Sound Therapy

The use of white noise or soothing sounds (sound generators, specialized applications) can help "mask" tinnitus and reduce its perception, particularly useful when falling asleep.

Hearing Aids

When associated with hearing loss, hearing aids correct hearing and significantly reduce tinnitus perception in many patients.

Cognitive Behavioral Therapy (CBT)

A highly effective approach for reducing the psychological distress associated with tinnitus by modifying the emotional response to the sound rather than the sound itself.

Stress Management

Relaxation techniques, meditation and regular physical activity: reducing overall stress often decreases the discomfort associated with tinnitus.
