Tinnitus Assessment

What Is Tinnitus?

Tinnitus is the perception of sound in the ears or head when no external source of that sound exists. People describe it in many ways — ringing, buzzing, hissing, humming, whooshing, whistling, or even a musical tone. For some it is a barely noticeable background presence; for others it is an intrusive, distressing companion that disrupts sleep, concentration, work, and emotional wellbeing. Tinnitus is not a disease in itself but a symptom — a signal from the auditory system that something has changed, whether that is age-related wear on the cochlea, noise damage, stress, or an underlying medical condition.

Tinnitus is remarkably common. The British Tinnitus Association (BTA) estimates that around 7.1 million adults in the UK experience tinnitus — roughly one in eight. Of these, approximately 1 million report that their tinnitus has a significant effect on their quality of life. The RNID (Royal National Institute for Deaf People) notes that tinnitus can occur at any age, though it becomes more prevalent with age and is closely associated with age-related hearing loss. Despite its prevalence, tinnitus remains widely misunderstood, and many people live with it for years without seeking help — often because they believe nothing can be done. This is a misconception. While there is currently no universal cure, a specialist tinnitus assessment is the essential first step towards effective management that can significantly improve quality of life.

Types of Tinnitus

Tinnitus is not a single condition — it presents in several forms, and understanding the type is important for guiding assessment and management:

Subjective tinnitus

This is by far the most common form, accounting for over 95% of cases. Only the person experiencing it can hear the sound. It is generated by the auditory system itself — usually as a result of changes in the cochlea, auditory nerve, or the brain's auditory processing centres. Subjective tinnitus is most often associated with hearing loss, but it can also occur in people with normal audiograms.

Objective tinnitus

In rare cases, the sound can actually be heard by an examiner using a stethoscope or sensitive microphone placed near the ear. Objective tinnitus has a physical, mechanical source — such as blood flow turbulence, muscle contractions in the middle ear, or Eustachian tube dysfunction. It accounts for fewer than 5% of cases and often has a treatable underlying cause.

Pulsatile tinnitus

Pulsatile tinnitus is a rhythmic sound that beats in time with your pulse. It is typically caused by altered blood flow near the ear — for example, due to narrowed blood vessels (atherosclerosis), high blood pressure, an arteriovenous malformation, or, rarely, a glomus tumour. Pulsatile tinnitus is a red flag that always warrants prompt medical investigation, as it can indicate an underlying vascular or structural condition that may need treatment.

Somatic tinnitus

Some forms of tinnitus are linked to the musculoskeletal system — particularly the jaw (temporomandibular joint, or TMJ) and the neck. Movements of the jaw, head, or neck can modulate the loudness or pitch of the tinnitus, suggesting a connection between the somatosensory and auditory systems.

What Causes Tinnitus?

Tinnitus has many potential triggers, and in many cases multiple factors interact. The most common causes and associations include:

• Age-related hearing loss (presbycusis): The most common association. As the cochlea deteriorates with age, the brain may generate phantom sounds to compensate for the reduced auditory input — a phenomenon likened to "phantom limb" sensation.
• Noise-induced hearing loss: Prolonged or sudden exposure to loud noise can damage the delicate hair cells of the cochlea, triggering tinnitus. This is common among musicians, construction workers, military personnel, and anyone who uses headphones at high volume. See our guide to protecting your hearing.
• Ear wax build-up: Impacted ear wax pressing against the eardrum can cause or worsen tinnitus. Professional ear wax removal often resolves tinnitus caused by this.
• Ear infections: Middle ear infections and chronic otitis media can produce tinnitus as a symptom.
• Meniere's disease: A condition affecting the inner ear that causes episodes of vertigo, fluctuating hearing loss, tinnitus, and a feeling of fullness in the ear.
• Otosclerosis: Abnormal bone growth in the middle ear can cause conductive hearing loss and tinnitus.
• Ototoxic medications: Certain drugs — including some antibiotics (aminoglycosides), chemotherapy agents (cisplatin), high-dose aspirin, and loop diuretics — can cause or worsen tinnitus as a side effect. Always discuss potential hearing effects with your prescriber.
• Stress and anxiety: While stress does not directly cause tinnitus, it can amplify the perception and distress associated with it, creating a vicious cycle.
• Head and neck injuries: Trauma to the head, neck, or jaw can trigger tinnitus through damage to auditory structures or altered nerve signalling.
• TMJ disorders: Problems with the temporomandibular joint can produce or modulate tinnitus.

In many cases, no single definitive cause is identified — but a thorough tinnitus assessment can rule out treatable conditions and guide the most effective management strategy.

What Does a Tinnitus Assessment Involve?

A specialist tinnitus assessment is a comprehensive evaluation that goes well beyond a standard hearing test. It is designed to characterise your tinnitus in detail, measure its impact, identify any underlying causes, and create a personalised management plan. Here is what to expect:

Detailed case history

Your audiologist will ask about the onset, duration, character, and pattern of your tinnitus — when it started, what it sounds like, whether it is constant or intermittent, whether it is in one ear or both, and whether anything makes it better or worse. They will also ask about your general health, medications, noise exposure history, stress levels, sleep quality, and any family history of hearing loss or tinnitus.

Ear examination

An otoscopic examination checks your ear canals and eardrums for physical causes such as ear wax, infection, or eardrum perforation.

Pure tone audiometry

A full hearing test is almost always included, as tinnitus is associated with hearing loss in the vast majority of cases. Even when a person believes their hearing is normal, audiometry frequently reveals a degree of loss — particularly in the high frequencies — that correlates with the tinnitus.

Tinnitus pitch and loudness matching

The audiologist plays tones through headphones and adjusts the frequency and volume until you identify the tone that most closely matches your tinnitus. This helps characterise the sound objectively and is useful for calibrating sound therapy devices.

Minimum masking level (MML)

This test determines the lowest level of external noise (typically broadband or narrowband noise) that is needed to just cover or "mask" your tinnitus. It provides insight into the severity and can help predict response to sound therapy.

Validated questionnaires

Standardised tools such as the Tinnitus Handicap Inventory (THI), the Tinnitus Functional Index (TFI), or the Tinnitus Questionnaire (TQ) are used to objectively measure the impact of tinnitus on your daily life — including effects on sleep, concentration, emotional state, and social function. These scores provide a baseline against which treatment progress can be measured.

Additional tests

Depending on your presentation, additional assessments may include tympanometry (to check middle ear function), otoacoustic emissions (to assess cochlear health), or a speech-in-noise test (if difficulty hearing in background noise is a concern alongside tinnitus).

Tinnitus and Hearing Loss — The Connection

Tinnitus and hearing loss are closely linked, though the relationship is not always straightforward. Research published by the British Society of Audiology (BSA) suggests that around 80–90% of people with tinnitus also have some degree of hearing loss, even if they are not aware of it. The prevailing theory is that when the cochlea is damaged — whether by ageing, noise, or disease — the brain receives less auditory input and "turns up the gain" on its internal amplifier, generating phantom sounds to fill the gap. This is known as the central gain model of tinnitus.

Conversely, not everyone with hearing loss develops tinnitus, and some people with tinnitus have entirely normal audiograms — a situation that may reflect damage at the level of the cochlear synapses (hidden hearing loss) rather than the hair cells themselves. Understanding this connection matters for management: when hearing loss and tinnitus co-exist, treating the hearing loss with hearing aids often reduces the perception of tinnitus significantly, because the brain receives the auditory input it has been missing and no longer needs to generate its own signal.

Management and Treatment Options

While there is currently no pill or procedure that cures most forms of tinnitus, a range of evidence-based management strategies can significantly reduce its impact. The NICE guideline on tinnitus (NG155) and the BSA Practice Guidance on Tinnitus both recommend a stepped-care approach, starting with education and self-management and escalating to specialist therapies as needed:

Education and counselling

Understanding tinnitus — what it is, why it happens, and that it is not dangerous — is itself therapeutic. Many people feel immediate relief when they learn that tinnitus does not signify a serious medical condition and that the brain can learn to habituate to the sound over time. Audiological counselling is a core component of every tinnitus management plan.

Sound therapy

Sound therapy uses external sounds to reduce the contrast between tinnitus and silence, making the tinnitus less noticeable. Options include bedside sound generators, smartphone apps (such as the BTA's free app), wearable sound generators, and environmental sound enrichment (playing background music or nature sounds). The goal is not to mask the tinnitus completely but to create a richer sound environment that allows the brain to deprioritise the tinnitus signal.

Hearing aids

Hearing aids are one of the most effective tools for managing tinnitus when hearing loss is present. By amplifying ambient sounds, hearing aids restore the brain's auditory input and reduce the internal amplification that drives tinnitus perception. Many modern hearing aids also include built-in tinnitus sound generators that can play soothing sounds (white noise, ocean waves, or notched sound therapy) alongside amplification. Providers such as Boots Hearingcare, Specsavers Audiology, and Hidden Hearing offer tinnitus-compatible hearing aids.

Cognitive Behavioural Therapy (CBT)

CBT is the psychological intervention with the strongest evidence base for tinnitus distress. It does not aim to eliminate the tinnitus sound but instead changes the way you respond to it — breaking the cycle of negative thoughts, anxiety, and hypervigilance that can make tinnitus feel unbearable. NICE (NG155) recommends CBT for tinnitus as a first-line psychological therapy. It is available through NHS Improving Access to Psychological Therapies (IAPT) services, audiology-embedded psychology clinics, and private therapists.

Tinnitus Retraining Therapy (TRT)

TRT combines structured counselling with long-term low-level sound therapy to promote habituation — the process by which the brain learns to reclassify tinnitus as a neutral, unimportant signal. A full TRT programme typically lasts 12 to 18 months and is offered by specialist tinnitus clinics.

Other approaches

• Mindfulness-based interventions: Mindfulness and relaxation techniques can help reduce tinnitus-related stress and improve coping.
• Sleep management: Since tinnitus is often most noticeable at bedtime, strategies for improving sleep hygiene — and using bedside sound therapy — are an important part of the plan.
• Ear wax removal: If wax is contributing, professional removal may alleviate or resolve symptoms.
• Medication review: If a medication is suspected of causing or worsening tinnitus, a review with your prescriber may be warranted.

Red Flags — When to Seek Urgent Medical Advice

Most tinnitus is benign and manageable, but certain presentations warrant prompt medical investigation. You should see your GP urgently or seek same-day medical advice if you experience:

• Pulsatile tinnitus: A rhythmic whooshing or throbbing in time with your heartbeat. This can indicate a vascular cause and requires investigation, usually including imaging such as MRI or CT angiography.
• Unilateral tinnitus: Tinnitus in one ear only, particularly if accompanied by hearing loss or a feeling of fullness. This may rarely indicate a vestibular schwannoma (acoustic neuroma) — a benign tumour on the auditory nerve — and typically warrants MRI investigation.
• Sudden onset tinnitus with hearing loss: Sudden sensorineural hearing loss is a medical emergency. If you lose hearing rapidly in one or both ears, with or without tinnitus, seek same-day medical attention. Early treatment with corticosteroids can improve outcomes.
• Tinnitus with neurological symptoms: Dizziness, facial weakness, numbness, or difficulty swallowing alongside tinnitus should prompt urgent assessment.

Your GP can examine your ears, arrange blood tests or imaging as needed, and make an urgent referral to ENT (ear, nose, and throat) or audiology.
