Tinnitus is the sensation of hearing sound when no external sound is present. Many people describe it as ringing, but it may also sound like buzzing, humming, hissing, clicking, roaring, or pulsating. Tinnitus is not a disease by itself. It is usually a symptom of an underlying ear, hearing, jaw, nerve, or circulation-related issue.

Why does tinnitus happen?
To understand tinnitus, it helps to know how hearing works. Sound travels through the ear canal, vibrates the eardrum, passes through the tiny bones of the middle ear, and reaches the cochlea in the inner ear. The cochlea contains delicate hair cells that convert sound vibrations into signals for the brain. When this system is damaged, irritated, blocked, or disrupted, the brain may interpret abnormal signals as sound even when no outside sound exists.
The main causes of tinnitus
Noise-induced hearing loss
Repeated exposure to loud sounds or a sudden blast can damage the inner ear and trigger tinnitus.
Age-related hearing loss
As hearing changes with age, the brain may compensate for reduced sound input and tinnitus can develop.
Earwax blockage
A buildup of wax can block the ear canal, reduce hearing, and sometimes cause ringing or pressure.
Ear infections and ear pressure problems
Infections, fluid, or middle-ear pressure changes can temporarily affect hearing and lead to tinnitus.
Ototoxic medicines
Some medicines may worsen tinnitus in certain patients, especially when taken in higher doses or over time.
Ménière’s disease
This inner ear condition may cause tinnitus along with vertigo, hearing loss, and a feeling of fullness in the ear.
Jaw, neck, or head-related issues
TMJ problems, jaw clenching, teeth grinding, and some neck or head conditions can trigger or worsen tinnitus.
Circulation-related causes
Pulsatile tinnitus may be linked to blood flow changes and should always be assessed by a specialist.
What does tinnitus sound like?
Tinnitus is different for every person. It may sound like ringing, buzzing, whistling, humming, clicking, hissing, roaring, or a heartbeat-like pulsing sound. It can affect one ear, both ears, or seem to come from inside the head.
When should you see an ENT specialist?
Tinnitus in only one ear; tinnitus that pulses with your heartbeat; sudden onset of tinnitus with hearing loss; tinnitus after a head injury; dizziness or balance problems with ear noise; or tinnitus that is disrupting sleep, concentration, work, or daily life.
Mild tinnitus after a loud event may settle, but persistent or worsening symptoms should not be ignored. A proper ENT assessment can help identify whether the cause is simple and treatable or needs further investigation.
How is the cause diagnosed?
An ENT specialist usually starts with a detailed history and ear examination. Depending on the symptoms, you may also need a hearing test and, in selected cases, additional investigations to rule out inner-ear or circulation-related causes.
How is tinnitus treated?
Treatment depends on the underlying cause. Common approaches include:
- Treating earwax blockage or infection
- Reviewing medicines that may be contributing
- Managing hearing loss with hearing aids when appropriate
- Using sound therapy or background sound to reduce awareness of tinnitus
- Using counseling or tinnitus-focused therapy to reduce distress and improve coping
- Improving sleep, reducing stress, and protecting the ears from loud noise
Frequently asked questions
Is tinnitus always permanent?
Not always. Some cases are temporary, especially when linked to noise exposure, wax, infection, or a short-term ear problem. Persistent tinnitus should be checked properly.
Can earwax cause ringing in the ears?
Yes. Earwax blockage can affect hearing and sometimes trigger ringing, pressure, or discomfort. It should be removed safely by a qualified professional when needed.
Is tinnitus dangerous?
Tinnitus is often not dangerous, but it can sometimes point to a condition that needs treatment. Urgent assessment is important if it starts suddenly with hearing loss, comes after head injury, or pulses with the heartbeat.
Can tinnitus be treated?
Many patients improve when the underlying cause is treated or when sound therapy, hearing support, and structured coping strategies are used.
Which doctor should I see for tinnitus?
An ENT specialist is the right doctor to assess persistent tinnitus, especially when it comes with hearing loss, vertigo, ear pressure, or one-sided symptoms.
