Tinnitus: causes, red flags and what actually helps

Tinnitus is hearing sound that does not come from an outside source, often described as ringing, buzzing, hissing, humming or whooshing. It is common and often linked with hearing loss, noise exposure, ear conditions, stress, medicines or changes in the auditory system, but it is not usually a sign of a dangerous disease. The important split is between tinnitus that needs prompt assessment and tinnitus that needs good hearing care, reassurance and coping support.¹²

What tinnitus is

Tinnitus is a perception generated by the hearing system and brain, not a sound other people can usually hear. It can be high-pitched, low-pitched, steady, intermittent, pulsing, musical, clicking or roaring. It may be quiet in the day and intrusive at night because there is less background sound. Some people notice it only in silence. Others find it affects sleep, concentration, work, mood and social confidence.

The mechanism is not one single thing. The National Institute on Deafness and Other Communication Disorders says tinnitus is often linked with hearing loss, and hearing aids are a main option for people who have both tinnitus and hearing loss.⁶ A common explanation is that reduced or altered input from the ear makes the auditory brain pay more attention to internal signal noise. Stress and threat monitoring can then make the sound feel louder or more important.

This is why "nothing can be done" is the wrong message. There may not be a simple cure, but there are several ways to reduce the impact. The aim is usually not to erase every trace of sound. It is to check for treatable causes, protect hearing, reduce fear, improve sleep and help the brain stop treating the tinnitus as an emergency.

Red flags

Most tinnitus can be assessed routinely, but some patterns need prompt action. The clearest emergency is tinnitus with sudden hearing loss. NICE hearing-loss guidance says adults with sudden onset hearing loss over 3 days or less within the past 30 days should be referred immediately, to be seen within 24 hours by ENT or an emergency department, if it is not explained by outer or middle ear causes.³

NICE says people with tinnitus and a high risk of suicide should be referred immediately to a crisis mental health management team.² In the UK, if tinnitus is making you feel unsafe or at risk of harming yourself, call 999 if life is at risk, use NHS 111 and select the mental health option for urgent support, contact your GP urgently, or call Samaritans free on 116 123 at any time.

Common causes

The commonest association is hearing change. This can be age-related hearing loss, past loud noise exposure, a single acoustic shock, earwax, middle-ear problems, Eustachian tube dysfunction, Meniere's disease, otosclerosis, ear infection, head or neck injury, jaw problems, migraine, blood pressure or vascular issues, anaemia, thyroid disease, diabetes, anxiety, depression, or medicines that affect hearing in susceptible people. NHS guidance lists hearing loss, Meniere's disease, anxiety or depression, thyroid disorders, multiple sclerosis and some medicines among links.¹

Pulsatile tinnitus is different from a steady ring. If the sound beats in time with the pulse, the cause may involve blood flow, raised pressure around the brain, vascular anatomy, middle-ear conditions or sometimes a benign turbulent-flow explanation. NICE recommends imaging for pulsatile tinnitus.² This does not mean panic, but it does mean it should not be dismissed as ordinary ringing.

Jaw and neck factors can modulate tinnitus in some people. If clenching, chewing, neck rotation or pressure around the jaw changes the sound, mention this. It may point to somatosensory tinnitus, temporomandibular joint dysfunction or muscle tension as part of the pattern. That does not remove the need for hearing assessment, but it changes the management options.

Tests and assessment

A useful tinnitus history includes which ear, whether it is pulsatile, whether hearing changed suddenly, vertigo, ear pain, discharge, fullness, noise exposure, jaw or neck triggers, sleep impact, mood impact, medicines, and whether the tinnitus is new, worsening or longstanding. A GP can check for wax, infection, eardrum problems, blood pressure and neurological signs where relevant.

NICE says all people with tinnitus should be offered an audiological assessment.² This is not just a hearing test. It helps identify hearing loss, asymmetry and patterns that may guide referral, hearing aids or further investigation. NICE also says to consider tympanometry when middle-ear or Eustachian tube dysfunction, or another conductive hearing-loss cause, is suspected.²

Imaging depends on the pattern. NICE says to offer MRI of the internal auditory meati for non-pulsatile tinnitus with associated neurological, otological, head or neck signs and symptoms, and to consider MRI for unilateral or asymmetrical non-pulsatile tinnitus even without those associated signs.² It says not to offer imaging for symmetrical non-pulsatile tinnitus without associated neurological, audiological, otological, head or neck signs and symptoms.²

Questionnaires can help when tinnitus is affecting life. NICE says to consider the Tinnitus Functional Index in adults to assess impact, and to ask about sleep because tinnitus commonly disrupts it.² This matters because the treatment target may be sleep, fear, concentration or avoidance rather than loudness alone.

What helps

The first helpful step is explanation. NICE says information should cover what tinnitus is, what may have caused it, what may happen in the future, what can make it worse, safe listening practices, impact on sleep, self-help and management options.² This may sound basic, but reducing fear is treatment. A frightened brain monitors the sound more closely.

If hearing loss is present, hearing aids can help communication and may reduce how dominant tinnitus feels. NICE recommends offering amplification devices to people with tinnitus who have hearing loss affecting communication, and considering them for people with tinnitus who have hearing loss even if they do not report communication difficulty.² NICE says not to offer amplification devices to people with tinnitus but no hearing loss.²

Sound therapy is often used practically, especially at night: quiet background sound, nature sounds, fans, radio at low volume, smartphone apps or bedside sound generators. The American Tinnitus Association describes sound therapy as using external noise to alter tinnitus perception or reaction, including masking, distraction or habituation approaches.⁵ NICE could not make a firm practice recommendation for sound therapy because evidence was not strong enough, so treat it as a low-risk coping tool rather than a proven cure.²

CBT-based approaches have the best evidence for reducing distress. NICE recommends a stepped approach for adults whose tinnitus still affects emotional and social wellbeing and day-to-day activities after tinnitus support, starting with digital tinnitus-related CBT, then group-based psychological interventions such as mindfulness-based cognitive therapy, acceptance and commitment therapy or CBT, then individual tinnitus-related CBT.²

A 2020 Cochrane review found 28 studies with 2733 participants. It concluded that CBT may reduce the negative impact of tinnitus on quality of life at the end of treatment, with low to moderate certainty evidence and few or no adverse effects, although longer-term evidence at 6 or 12 months was limited.⁴ That means CBT is not "all in your head". It targets the fear, attention, avoidance and sleep disruption that make tinnitus dominate life.

Avoid two traps. The first is over-protection from normal sound. Ear protection is sensible for loud music, machinery, shooting, clubs and power tools, but wearing earplugs all day in normal environments can make the auditory system more sensitive. The second is chasing expensive cures. Use the insights section to sanity-check tinnitus product claims, and the stack builder if supplements or sleep aids are piling up.

A practical plan

For new tinnitus, write down the start date, whether one or both ears are involved, whether it pulses with the heartbeat, whether hearing changed, whether vertigo or facial symptoms are present, and any recent noise exposure, infection, wax, new medicine, head injury or jaw flare. That timeline helps the GP or audiologist triage risk.

For longstanding tinnitus, focus on the vicious cycles: silence, sleep loss, fear, monitoring, avoidance, stress and reduced activity. A realistic plan might include hearing assessment, hearing aids if indicated, safe sound enrichment at night, caffeine or alcohol experiments only if they clearly affect symptoms, sleep treatment, relaxation practice, tinnitus support, and CBT-based help if distress remains high.

The health library can help you compare tinnitus with migraine, vertigo, sleep problems, anxiety, hearing loss and metabolic causes such as thyroid disease. If you are preparing for an appointment, start here and bring a short symptom timeline rather than a long list of theories.
