What Is Tinnitus? A Complete Guide to the Ringing in Your Ears
By DEB’s Audiology Team – March 2026 – 12 min read
Article Summary
Tinnitus affects an estimated 14% of adults in India — around 200 million people. For most, it is a background nuisance. For a significant minority, it becomes a serious and ongoing disruption to sleep, concentration, and mental health.
This article covers:
- What tinnitus is and why it happens in plain, accurate language
- The full range of sounds it produces — ringing, buzzing, hissing, pulsing, clicking
- The most common causes, from noise exposure and hearing loss to earwax and medication
- The important distinction between subjective tinnitus and pulsatile tinnitus (which can indicate a vascular problem)
- What makes tinnitus worse — noise, stress, caffeine, silence
- How tinnitus affects sleep, concentration, and mental health
- When symptoms warrant an audiological assessment
The key takeaway: tinnitus cannot always be cured, but it can almost always be managed. Early assessment identifies the cause, rules out serious underlying conditions, and opens the path to the right treatment.
You are lying in bed at night, and there it is — a faint but persistent ringing, buzzing, or hissing that no one else can hear. Or perhaps you noticed it after a particularly loud concert, a long commute with earphones in, or simply one morning when you woke up and it had appeared from nowhere.
Tinnitus is one of the most common audiological complaints in the world. In India, it is estimated to affect approximately 14% of adults. Yet it remains widely misunderstood — and widely undertreated.
What Is Tinnitus?
Tinnitus is the perception of sound without an external source. It is a sound that originates inside the auditory system rather than in the environment around you. Only you can hear it.
The word comes from the Latin tinnire, meaning ‘to ring’. It is not a disease in itself but a symptom — an indication that something in the auditory pathway, from the outer ear to the brain’s sound-processing centres, is not functioning as it should.
Tinnitus can be temporary or persistent. It can affect one ear or both. It can be quiet and ignorable, or loud and dominating. Understanding what type of tinnitus you are experiencing, and what is causing it, is the starting point for managing it effectively.
What Does Tinnitus Sound Like?
Tinnitus is not a single sound. The most commonly reported descriptions include:
Ringing: A clear, high-pitched ring, similar to the sound after a loud noise exposure. The most frequently reported type.
Buzzing: A low, electrical humming or buzzing, often described as similar to fluorescent lighting.
Hissing or whistling: A continuous white-noise-like sound, sometimes compared to steam escaping or a kettle boiling.
Clicking: Rhythmic or irregular clicking, often associated with muscle contractions in or around the ear.
Pulsing: A whooshing or thumping that beats in time with the heartbeat. This is called pulsatile tinnitus and warrants specific investigation — see below.
Many people find the sound shifts over time — changing in pitch, volume, or character. Some notice it is significantly worse in quiet environments, particularly at night.
What Causes Tinnitus?
Tinnitus has many causes. In most cases it is associated with some degree of hearing system disruption, though the precise mechanism is not always straightforward.
Noise-Induced Hearing Loss
The most common cause. Prolonged or repeated exposure to loud sound damages the hair cells in the cochlea — the inner ear’s sound-sensing organ. These cells cannot regenerate. As they deteriorate, the auditory system can generate phantom signals that the brain interprets as sound. In India, urban noise levels, occupational exposure, and widespread earphone use at high volumes are all significant contributors.
Age-Related Hearing Loss (Presbycusis)
The gradual decline of cochlear hair cells over time is a normal part of ageing — and tinnitus frequently accompanies this process. Many adults over 60 experience both hearing loss and tinnitus simultaneously, as the underlying cause is the same.
Earwax Blockage
An accumulation of earwax in the ear canal can cause tinnitus by creating pressure and altering the acoustic environment of the ear. This is one of the most straightforward causes to address — safe earwax removal often resolves or significantly reduces tinnitus in these cases.
Ototoxic Medications
A range of medications can damage the inner ear as a side effect, causing or worsening tinnitus. These include certain antibiotics (particularly aminoglycosides), some chemotherapy agents, high doses of aspirin, and certain diuretics. If tinnitus began after starting a new medication, this connection should be discussed with the prescribing doctor.
Middle Ear Conditions
Middle ear infections, fluid behind the eardrum, or changes in ear pressure can all produce tinnitus. These cases are often associated with conductive hearing loss and may be fully reversible once the underlying condition is treated.
Stress and Anxiety
While stress does not cause tinnitus directly, it is one of the most consistently reported aggravating factors. Many people first become aware of their tinnitus during periods of heightened stress — and those who are anxious about the sound often find it amplified as a result. The relationship between tinnitus and the limbic system — the brain’s emotional centre — is an important part of why it affects quality of life so significantly.
Subjective Tinnitus vs Pulsatile Tinnitus
The vast majority of tinnitus — around 99% — is subjective: only the person experiencing it can hear it. This is what most people mean when they say they have tinnitus.
Pulsatile tinnitus is different. It is a sound that pulses in rhythm with the heartbeat, often described as a whooshing or thumping. Unlike subjective tinnitus, pulsatile tinnitus can sometimes be heard by an examining clinician. It is less common but more clinically significant, as it can indicate changes in blood flow near the ear, high blood pressure, vascular abnormalities, or rarely, more serious conditions.
If your tinnitus pulses in time with your heartbeat, seek an assessment promptly. Pulsatile tinnitus should always be investigated to rule out vascular causes.
What Makes Tinnitus Worse?
Many people notice their tinnitus fluctuates — louder on some days than others. Common triggers and aggravating factors include:
- Loud noise exposure — both a cause and an aggravator of existing tinnitus
- Stress, anxiety, and emotional distress
- Poor or disrupted sleep — fatigue amplifies tinnitus perception
- Caffeine and alcohol — both can increase tinnitus intensity in some people
- Complete silence — without background sound, the brain focuses more on tinnitus
- Certain medications — particularly at high doses
- Earwax buildup or ear infections
Identifying personal triggers is an important part of tinnitus management, as avoiding or moderating them can significantly reduce the burden of the condition.
How Tinnitus Affects Daily Life
For many people, tinnitus is a background nuisance that they learn to live alongside. For a significant minority — research suggests around 20% of those with tinnitus experience it as severely bothersome — it becomes a persistent disruption to daily functioning.
Sleep is most commonly affected. Lying in a quiet room amplifies tinnitus perception, making it harder to fall asleep or stay asleep. Concentration difficulties are also frequently reported, particularly in quiet environments such as offices or libraries. Over time, untreated bothersome tinnitus is associated with increased rates of anxiety, depression, and social withdrawal.
The impact is not proportional to the loudness of the sound. People with objectively quiet tinnitus can experience severe distress, while others with louder tinnitus manage it with minimal difficulty. The determining factor is largely how the brain has learned to respond to the signal — which is also, importantly, why effective treatments exist.
When Should You See an Audiologist?
If your tinnitus has persisted for more than a few days, is significantly affecting your sleep or concentration, or began suddenly without an obvious cause, an audiological assessment is warranted. Early assessment matters because it can identify treatable underlying causes and rules out serious conditions.
You should seek assessment sooner if any of the following apply:
- Tinnitus that began suddenly in one ear only
- Pulsatile tinnitus — beating in time with your pulse
- Tinnitus accompanied by sudden hearing loss
- Tinnitus accompanied by vertigo or balance problems
- Tinnitus that is significantly worsening over time
A comprehensive tinnitus assessment at DEB’s Audiology includes a full hearing evaluation, a detailed case history, and a discussion of management options tailored to your specific presentation. Both Dr. Nabarun Deb and Dr. Sarmistha Nayak have specialist experience in tinnitus assessment and management.
What to Do Next
If tinnitus is affecting your sleep, your concentration, or your quality of life, the right step is a comprehensive assessment to understand what is causing it and what can be done.
