Tinnitus is not one condition. It is a symptom — the perception of sound without an external source — that can arise from several completely different mechanisms. The two most important categories are auditory tinnitus and somatic tinnitus, and understanding which one you have is arguably the most important step in finding an approach that actually helps.

Most people with tinnitus are assessed only for the auditory type. If the hearing test comes back normal, they are often told nothing more can be done. For a significant number of them, this conclusion is premature — because their tinnitus is somatic, and somatic tinnitus has a different origin, a different mechanism, and a different treatment pathway.

Auditory Tinnitus: When the Ear Is the Source

Auditory tinnitus originates within the auditory system itself — the cochlea, the auditory nerve, or the central auditory processing pathways in the brain. The most common causes include:

  • Noise-induced hearing loss. Damage to the hair cells of the cochlea from prolonged or acute loud noise exposure. This is the most common cause of chronic auditory tinnitus.
  • Age-related hearing loss. Progressive degeneration of cochlear function produces tinnitus in a significant proportion of older adults.
  • Ototoxic medication. Certain drugs — including some antibiotics, diuretics, and chemotherapy agents — can damage the cochlea and trigger tinnitus.
  • Ménière's disease. A disorder of the inner ear characterised by episodes of vertigo, fluctuating hearing loss, and tinnitus.
  • Acoustic neuroma. A benign tumour on the auditory nerve that can produce unilateral tinnitus and hearing loss.

Auditory tinnitus is typically constant, does not change with body position or movement, and is usually accompanied by some degree of measurable hearing loss. It is generated within the auditory system and perceived as sound because the brain is receiving and processing an abnormal signal from that system.

Current evidence does not support any treatment that reliably eliminates auditory tinnitus. Management focuses on reducing distress — through sound therapy, cognitive behavioural therapy, and tinnitus retraining therapy — rather than eliminating the sound itself.

Somatic Tinnitus: When the Body Is the Source

Somatic tinnitus arises from the musculoskeletal system rather than the auditory system. The word somatic simply means of the body — and in this context, it refers to tinnitus that is generated or modulated by structures outside the ear: most commonly the cervical spine, the jaw, and the muscles of the head and neck.

The neurological basis for this is well established. The upper cervical spine shares neural connections with the cochlear nucleus — the brainstem structure that processes auditory input. When there is chronic tension, restricted movement, or dysfunction in the upper neck, these pathways can become sensitised. The cochlear nucleus begins receiving abnormal input from the cervical region and generating a sound perception in response.

The jaw — specifically the temporomandibular joint and the muscles of mastication — has a similar relationship with the auditory system through shared nerve supply and proximity to the middle ear. Jaw dysfunction is one of the most underrecognised contributors to tinnitus.

The Defining Feature of Somatic Tinnitus: Modulation

The single most important distinguishing feature of somatic tinnitus is somatosensory modulation — the ability to change the tinnitus through physical action. This is not a subtle or ambiguous phenomenon. People with somatic tinnitus can typically alter the pitch, volume, or quality of the sound by:

  • Turning the head to one side
  • Looking up or down
  • Pressing on specific muscles at the base of the skull or side of the neck
  • Clenching or moving the jaw
  • Applying pressure to the temporomandibular joint area
  • Sustained postures — the tinnitus is often worse after prolonged sitting or screen use

If any of these actions change your tinnitus — even temporarily, even subtly — there is a somatic component involved. The musculoskeletal system is contributing to the signal your brain is interpreting as sound.

It is worth noting that somatic and auditory tinnitus are not mutually exclusive. A person can have cochlear damage that generates a baseline tinnitus, with an additional somatic component from cervical dysfunction that modulates and amplifies it. In these cases, addressing the somatic component will not eliminate the tinnitus entirely — but it can meaningfully reduce its intensity and variability.

How the Assessment Differs

Auditory tinnitus is assessed through audiology — pure tone audiometry, speech discrimination testing, and otoscopic examination. These are the standard investigations offered when someone presents with tinnitus.

Somatic tinnitus requires a different assessment entirely — one that most ENT consultations do not include. A thorough somatic assessment looks at:

  • Cervical range of motion and joint mobility, particularly at C1-C2 and C2-C3
  • Deep cervical flexor strength and activation patterns
  • Trigger point examination of the sternocleidomastoid, suboccipitals, upper trapezius, and masseter
  • Temporomandibular joint mobility and symptom provocation
  • Postural assessment — forward head posture is strongly associated with somatic tinnitus
  • Somatosensory modulation testing — systematic assessment of whether and how physical actions change the tinnitus

If this assessment has not been performed, the conclusion that nothing can be done for your tinnitus is incomplete. It may be accurate for the auditory component. It says nothing about whether a somatic component is present and treatable.

Treatment: Why the Distinction Changes Everything

This is where the distinction between somatic and auditory tinnitus becomes practically critical.

Auditory tinnitus does not respond to physiotherapy, cervical exercises, or jaw treatment. If the source is cochlear damage or central auditory processing changes, addressing the neck will not change the signal. Management strategies — CBT, sound therapy, habituation — are the appropriate approach.

Somatic tinnitus, by contrast, can respond meaningfully to targeted musculoskeletal intervention. Specifically:

  • Upper cervical mobilisation — restoring normal movement at C1-C2 and C2-C3 reduces the abnormal neural input to the cochlear nucleus
  • Trigger point release — deactivating the sternocleidomastoid and suboccipital trigger points that refer into the ear and temporal region
  • Deep cervical flexor training — reducing the chronic overload on the posterior cervical structures that drives the sensitisation
  • Jaw and TMJ treatment — addressing temporomandibular dysfunction where it contributes to the tinnitus

The two published studies underpinning the Reliev program document consistent results with this approach across patients treated in multiple countries. Not every patient achieves complete resolution — but meaningful reduction in tinnitus intensity and frequency is achievable in patients where the somatic component is correctly identified and addressed.

What to Do If You Are Unsure Which Type You Have

Start with the modulation test. Over the course of one week, systematically try the actions listed above and note whether any of them change your tinnitus. Be thorough — try each action for at least 30 seconds and pay close attention to any change in pitch, volume, or quality.

If you identify consistent modulation, pursue a somatic assessment with a physiotherapist experienced in cervical dysfunction and tinnitus. If you have not yet had a standard audiological assessment, have that done first to rule out significant auditory pathology.

If you identify no modulation whatsoever, the tinnitus is more likely to be purely auditory, and the focus should shift to management and habituation strategies.

The question is not whether your tinnitus can be treated. The question is whether the right type of assessment has been done to find out.
