What Is Tinnitus? A Clinician's Plain-English Guide

Tinnitus is the perception of sound when there's no external source, most commonly a ringing, buzzing, hissing or humming in one or both ears. It affects around 10 to 15% of UK adults at some point. It isn't a disease in itself. It's a symptom your auditory system is responding to something. Below I'll explain what it is, what causes it, what actually helps, and when to take it seriously.

What tinnitus actually is

Tinnitus is a phantom sound. It isn't generated by the world around you. It's generated inside your auditory system. The most common form is a high-pitched ringing or hiss, but patients can describe it as sounding like almost anything.

It's extremely common. The British Tinnitus Association estimates around 7 million people in the UK experience it. About 1 in 10 of those find it significantly distressing.

Why your brain creates a sound that isn't there

The leading theory is that tinnitus is the brain's response to reduced auditory input. When your inner ear stops sending the brain certain frequencies (because of noise damage, age-related loss, blocked ears, or other causes) the brain compensates by generating its own activity in those frequency channels. You experience that activity as sound.

This is why most tinnitus is paired with some degree of hearing loss, even subtle high-frequency loss the patient hasn't noticed. And it's why hearing aids, by restoring input, often reduce tinnitus.

Common causes

- Noise exposure: concerts, power tools, shooting, occupational noise. The single most common trigger.
- Age-related hearing loss: even mild high-frequency loss can produce tinnitus.
- Ear wax blockage: tinnitus that resolves after wax removal is very common.
- Middle ear conditions: infections, eustachian tube dysfunction, glue ear.
- Ototoxic medications: high doses of aspirin, some antibiotics, some chemotherapy drugs.
- Stress, anxiety and poor sleep: they don't cause tinnitus, but they amplify the perception of it.
- TMJ (jaw joint) issues, neck tension and dental problems: somatosensory tinnitus.
- Less common: Meniere's disease, vestibular schwannoma, pulsatile causes related to blood flow.

When to take tinnitus seriously

See a clinician promptly if your tinnitus is:

- Sudden onset in only one ear
- Pulsatile (in time with your heartbeat)
- Associated with sudden hearing loss
- Associated with dizziness, vertigo or balance issues
- Following a head injury
- Severe enough to disrupt sleep, mood or concentration

One-sided tinnitus and pulsatile tinnitus in particular warrant ENT review and sometimes imaging.

What actually helps

Step 1: Get assessed

A proper audiological assessment is the first step. We measure your hearing across all frequencies, check for any wax or middle-ear issue, characterise the tinnitus (pitch, loudness, masking), and rule out red flags. Without this, every treatment is guesswork. Lenire is a tinnitus treatment we work with most at the Hear Now Clinic.

Step 2: Treat the cause where possible

If wax is blocking the canal, remove it. If a middle-ear infection is present, treat it. If a medication is ototoxic, your GP may adjust the dose. If hearing loss is present, fit hearing aids. They're the single most effective intervention for tinnitus paired with measurable loss.

Step 3: Sound therapy

External sound (music, podcasts, environmental sound, dedicated sound generators, hearing aid masking programs) reduces tinnitus contrast. Silence makes tinnitus louder. Sound enrichment makes it quieter. This is one of the few things every clinician agrees on.

If necessary proceed to seek further treatments

Step 4: Cognitive Behavioural Therapy (CBT)

Tinnitus distress is largely about the brain's emotional response to the sound, not the sound itself. CBT for tinnitus has strong evidence. It reduces distress and improves quality of life without changing the sound. The BTA has a list of UK clinicians.

Step 5: Lenire

Lenire is a newer device (bimodal neuromodulation) that combines sound therapy with mild electrical stimulation of the tongue. Large clinical trials showed roughly 86% of patients had meaningful reduction in tinnitus impact after 12 weeks of treatment. Hear Now Clinic is Neuromod's NI partner for Lenire. A full 6-month course is £3,600 including all fittings and follow-ups. It's not for everyone (we screen carefully) but for the right patients it is a life changing treatment.

What doesn't help

Ear candling, generic "tinnitus relief" supplements (ginkgo, magnesium, lipoflavonoid), and most over-the-counter "miracle" devices have no convincing evidence. Avoid them. They're expensive disappointments.

Living with tinnitus

Many people's tinnitus fades from awareness once it's managed properly. That's called habituation. It's the brain learning the sound isn't important. Stress, fatigue and silence make it louder. Good sleep, sound enrichment, treating any hearing loss and managing your reaction to it make it quieter.

Tinnitus is something to address, not something to fear. The vast majority of cases can be substantially reduced in impact.

Frequently asked questions

Will my tinnitus ever go away?
For some people, especially after a clear trigger like a single noise exposure, it does fade in weeks to months. For others it's chronic but can be managed to the point of barely noticing it. Habituation is realistic for most patients.

Is tinnitus a sign of something serious?
Usually not. But one-sided, pulsatile or sudden-onset tinnitus, or tinnitus with hearing loss, dizziness or after a head injury, deserves prompt clinical review.

Do hearing aids help tinnitus?
Yes, if you have measurable hearing loss. Restoring missing input reduces the brain's compensatory activity. Most modern hearing aids also have dedicated tinnitus masking programs.

Does Lenire work?
It works for at least 86% of suitable patients in clinical trials. We assess suitability carefully. It's not right for every type of tinnitus. Patients with tinnitus reactivity to sound and a clear baseline hearing profile tend to respond best.

Can I buy a tinnitus app and self-treat?
Sound-enrichment apps can help. They don't replace assessment. Treat the cause first, layer sound therapy on top.

Does stress cause tinnitus?
Stress doesn't cause tinnitus, but it amplifies it. Managing stress, sleep and anxiety reliably reduces tinnitus impact.
