Tinnitus: What It Is, What Causes It And What Actually Helps

Tinnitus is one of those symptoms that arrives without an explanation and leaves you with a search box. The NIDCD describes it as hearing a sound when no other sound is present. It is a symptom rather than a disease… a description of what your auditory system is reporting rather than a diagnosis of what is wrong.

This page is written by an independent editorial desk with an affiliate relationship to a hearing supplement and no relationship to any clinician, hearing-aid provider or therapy service. It is educational information rather than medical advice, and it does not diagnose you or propose a treatment plan. It covers the mechanics, which parts of the answer have evidence behind them, and the moments when waiting is the wrong call.

The word covers a wide range of experiences. For one person it is a faint high-pitched whistle that appears only in a silent room. For another it is a persistent roar that competes with conversation. A third hears clicks or a pulse. Those descriptions are worth separating, because they are useful to a clinician, but the underlying mechanism is usually similar: the auditory nerve is generating activity that the brain interprets as sound, without a matching sound arriving at the ear.

The sound is a report. It tells you something is happening in the auditory pathway; it does not tell you what. Wax, a middle-ear problem, a medicine, noise damage, age-related change, an inner-ear disorder, a head injury, a blood-flow problem and a jaw or neck problem can all produce it.

Because the sound is generated internally, you will always hear it more clearly in a quiet room. That is a feature of the mechanism. It is not a sign that the problem is worse than you think.

And there is no single treatment for tinnitus, because there is no single cause. Anything sold as a universal fix is either treating one narrow cause while implying it treats all of them, or selling hope.

• It is a symptom. Treat the cause where a cause can be found and treated, and the sound often changes with it.

• It is common and usually not dangerous in itself. The NICE guideline on tinnitus notes that although it commonly accompanies hearing loss, it is not commonly associated with other underlying physical problems.

• It is not measurable by sound. With the large majority of cases, no device can hear the noise or record its loudness, which is why assessment relies on hearing tests and questionnaires rather than on measuring the sound.

• There is no cure. The NIDCD states this directly, and any product page implying otherwise is making a claim that no evidence supports.

The distinction is not a technicality. It changes what happens next.

Subjective tinnitus is the normal case. The sound is generated somewhere in the auditory pathway and perceived only by the person experiencing it. Because no microphone can pick it up, diagnosis is based on history, ear examination and hearing tests, and management is based on reducing the impact rather than removing the sound.

Objective tinnitus is rare, and means a sound is actually being produced in or near the head and can be detected with a microphone placed over the ear or a stethoscope applied to the neck. That means there is a physical sound source: something vascular or muscular is a typical explanation. Guidance for tinnitus lists persistent objective tinnitus as a reason for referral, because a detectable sound deserves to be traced to its source rather than managed with earplugs and white noise.

The list below is not a ranking to self-diagnose against. It is roughly the order in which a clinician works through the causes, which is useful for two reasons: you may recognise the pattern of your own situation, and you will have a better idea of which specialist you need.

Noise-induced hair-cell damage

This is the leading cause, and the best understood. The NIDCD describes how loud noise damages sensitive structures in the inner ear, and states that most noise-induced hearing loss comes from damage to, and eventual death of, the cochlear hair cells. It also states that, unlike the hair cells of birds and amphibians, human hair cells do not grow back… they are gone for good. Loud noise can also cause tinnitus directly, and tinnitus can occur in one ear or both.

Two numbers from the NIDCD. Sounds at or below 70 dBA, even over long periods, are unlikely to damage hearing, while long or repeated exposure at or above 85 dBA can. Its table of average levels places music through headphones at maximum volume, sporting events and concerts in the 94 to 110 dBA band. It is the combination of level and duration that does the damage, which is why a short burst of loud sound and a long evening at a moderate volume are different risks.

The NIDCD also states that noise-induced hearing loss is the only type of hearing loss that is completely preventable.

Age-related change in the inner ear

Hearing is not held up by muscles or bones. It depends on hair cells and a functioning auditory nerve, and both change with age. Tinnitus that arrives in later life is frequently associated with age-related hearing loss rather than appearing out of nowhere, which is why an audiogram matters more in that situation and why amplification is the intervention most often offered first.

The practical consequence is that tinnitus in an older adult should not be treated as an isolated curiosity. It is usually a flag about the auditory system as a whole, and the useful question is what the audiogram shows alongside it.

Medicines that cause or worsen tinnitus

The NIDCD states that more than 200 medicines can cause tinnitus when they are started or when they are stopped. A new sound can therefore appear after a routine prescription for something entirely unrelated to your ears, and the same sound can appear in the days after you finish a course.

The pattern is classically reversible: a sound that appears alongside a new medicine and settles when the medicine changes is a different situation from one that appears with no medication event at all. StatPearls in the NCBI Bookshelf uses high-dose aspirin as its worked example of a drug that can produce tinnitus and where the problem resolves when it is stopped.

Do not stop a prescribed medicine because of ringing in the ears. Talk to the prescriber or a pharmacist. What is useful is to notice the timing, list everything you take including over-the-counter painkillers, and hand that list over at your appointment. Nobody else can spot that pattern for you.

Earwax and middle-ear problems

Impacted wax can produce a surprising amount of trouble for something so ordinary: a ringing or humming sensation, a feeling of pressure, and hearing that seems dull or blocked. The reason is mechanical. Wax sitting against the eardrum can reduce how much sound gets through, and that change in input is enough to make tinnitus audible in a way it was not before.

This is usually the easiest category to resolve, because the cause is often visible on examination and often reversible. It is also the reason a clinician looks in the ear before anything else. Middle-ear problems, including fluid behind the eardrum and infections, can produce the same pattern.

The caution belongs here too: insert nothing into the ear canal to remove wax, and be sceptical of any product that promises to scoop it out. Wax removal is a job for someone who can see what they are doing, and self-directed removal is a common route to a perforated eardrum or an inflamed canal.

Meniere’s disease and otosclerosis

Meniere’s disease is an inner-ear disorder characterised by episodic vertigo, fluctuating sensorineural hearing loss, tinnitus and aural fullness. Recognising it matters because tinnitus on its own looks benign, while tinnitus arriving with episodes of spinning and hearing that comes and goes does not. If your sound is accompanied by attacks of dizziness, or by a blocked feeling that comes and goes over hours, that is a pattern for an ear, nose and throat specialist rather than something to self-manage.

Otosclerosis is a process in which abnormal bone remodelling around the inner ear affects the transmission of sound, most often by fixing the stapes at the oval window. StatPearls notes that the most frequent presenting complaint is hearing loss, usually gradually worsening over years, while tinnitus and vertigo may also occur. Where hearing loss and tinnitus appear together in this pattern, the underlying middle-ear problem is the thing to be assessed.

Head and neck injury, and vascular causes

Trauma is a recognised cause. After a head or neck injury, the auditory nerve, the small bones of the middle ear and the membranes around them can all be affected, and the result may be hearing loss, a blocked sensation, a full or hollow-sounding ear, and tinnitus. Because the mechanism differs, the pattern of onset is often useful: it follows a specific identifiable event rather than appearing gradually.

Vascular causes are the reason <a href="/pulsatile-tinnitus/">pulsatile tinnitus</a> is treated as its own page. A sound that keeps time with the heartbeat is a different clinical category, frequently vascular or mechanical, and the investigations for it are different. If that is what you have, the <a href="/pulsatile-tinnitus/">pulsatile tinnitus page</a> is the relevant one, and it is not something to approach with a product.

The typical sequence looks like this.

1. History. When it started, whether it is one-sided, whether it pulses, what the noise exposure history is, what medicines you take, and what the sound does to your sleep, concentration and mood. The best thing you can do is write it down before the appointment.

2. Examination of the ear. Looking for wax, infection, fluid or membrane changes. This is often where the answer is found.

3. Audiometry. A hearing test across different pitches, which establishes whether you have measurable hearing loss, how much, and whether it is the same on both sides. It also provides the baseline against which any future change is judged.

4. Questions about impact. Tinnitus questionnaires are used to establish how much the sound is affecting daily life. That is not a trivial step: it is what makes improvement measurable rather than anecdotal, and it is what allows a treatment to be judged against something other than memory.

5. Referral where the pattern calls for it. Guidance for tinnitus lists persistent one-sided tinnitus, persistent pulsatile tinnitus and persistent objective tinnitus among the reasons to refer to specialist assessment.

Imaging is not routine, and that is not a gap. The NICE guideline found no evidence supporting routine imaging for non-pulsatile tinnitus, and recommends scanning when there are neurological or head and neck signs and symptoms such as facial weakness, vertigo or asymmetric hearing loss. It also recommends offering imaging to people with pulsatile tinnitus, because in that group the causes include vascular and other significant findings. Scans are useful in particular patterns of symptoms.

The NIDCD position frames the whole conversation: there is currently no cure for tinnitus. The goal is diagnosis, protection and management, not eradication.

The NIDCD lists the recognised approaches as sound therapy, hearing aids, behavioural therapy, tinnitus retraining therapy and, in some cases, medication. Those are broadly the same list the modern evidence review supports.

None of them removes the sound. They change the relationship between you and the sound, or change how much usable signal reaches the cochlea, and in a minority of people they help considerably more than that. Cognitive behavioural therapy is the clearest example. The benefit it produces is a change in distress and in how automatically the brain responds to the sound, which is living better with tinnitus rather than removing it.

Two practical notes on the table. Sound therapy is usually the cheapest evidenced option by a wide margin, because a bedside generator, a wearable device or a phone app costs a fraction of a course of therapy, and its support comes largely from being used alongside other approaches rather than alone. Amplification is the intervention with the longest evidence base, and the reason is mechanical: hearing loss usually means less sound reaching the cochlea, and a hearing aid addresses that directly.

Read the 2014 AAO-HNSF clinical practice guideline alongside the 2025 umbrella review. It is more cautious on several behavioural options, and it predates a decade of further systematic reviews. Where they differ, the more recent synthesis is the better guide to what to ask a clinician for.

There is a simple trap in the middle of the night. The room is quiet, so the sound is unmistakable. You check whether it has stopped, and in doing so you are attending to it. The more attention it gets, the more present it becomes, and the more it fragments sleep. The following day, being tired makes it worse again. That loop is the mechanism, and it is why so much of what helps is about attention and sleep rather than the ear.

A sound that has been present for a while and is not changing does not mean damage is progressing. The loop, not the volume, is driving the distress.

• Do not engineer silence to escape it. A fan, a radio, a shower or a low-level sound at night gives the brain something to sit on, and that is sound therapy in its cheapest form.

• Treat sleep as a target rather than a consequence. A consistent bedtime and a fixed wake time do more for tinnitus annoyance than most products in this category, because being rested changes how the sound is interpreted the next day.

• Do not check whether it is there. Repeatedly testing for the sound is what makes it louder in perception, and it is the habit most tinnitus advice points at. It is a habit rather than a treatment.

• Be honest about caffeine. It is widely reported as an aggravator, and the clinical evidence that it causes tinnitus is weak. But if you are drinking a lot of it in the evening and it is fragmenting your sleep, reducing it is a reasonable self-experiment, not a medical claim.

• Some people find earplugs make it worse. Blocking the outside world in a quiet room removes the contrast that would otherwise mask the sound. If that is your experience, sleep with background sound instead.

Stress belongs in the same list. Most people with long-standing tinnitus report that stress, anxiety and poor sleep make it more intrusive, and the therapies with the strongest trial support for tinnitus distress are behavioural ones that work on exactly that relationship. That is also why cognitive behavioural therapy has better trial support than anything in the supplement aisle, and why an assessment that found nothing treatable still leaves a sensible next step.

Supplement marketing for tinnitus is one of the most aggressive categories in consumer health, so here is the actual evidence rather than a vague warning.

Zinc. The Cochrane review of oral zinc supplementation for tinnitus included three trials with 209 participants. The authors found no evidence that zinc improves tinnitus symptoms in adults, rated the quality of the evidence as very low, and noted that the three studies differed enough in participants, follow-up and outcome measurement that they could not be combined. They were also explicit that some authors and websites had been encouraging zinc use on the strength of a plausible mechanism, and that the review could not support that conclusion.

Ginkgo biloba. The 2022 Cochrane review pooled twelve studies and 1,915 participants and concluded that ginkgo may have little to no effect on tinnitus symptom severity compared with placebo, at very low certainty, with no significant difference in adverse effects. The authors noted that European and German tinnitus guidelines recommend against ginkgo for this indication. The earlier 2013 review, based on four trials and 1,543 participants all judged to be at low risk of bias, reached the same conclusion. Those were well-run trials that failed to find an effect, rather than promising research that has been underpowered.

The pattern. Both reviews also draw attention to how strongly expectation affects self-reported tinnitus outcomes, which is the main reason to treat any before-and-after account, favourable or not, with care.

1. Hearing that dropped suddenly, over hours or days. Sudden sensorineural hearing loss is defined in the clinical guideline as a loss of 30 dB or more over three consecutive frequencies within 72 hours. The guideline recommends audiometry as soon as possible and notes that corticosteroids may be offered within two weeks of onset. That is a two-week window, and it is the single most time-critical item on this page.

2. A sudden onset in one ear, especially with dizziness or weakness. The AAO-HNSF patient information on sudden hearing loss notes that it usually affects one ear and may come with dizziness, ringing or a feeling of pressure, and advises seeing a healthcare provider as soon as possible.

3. Tinnitus in one ear only, that persists. The NICE guideline lists persistent one-sided tinnitus as a reason to refer for specialist assessment and management.

4. A sound that pulses in time with your heartbeat. This is a different clinical category with vascular and mechanical causes, some of which need imaging. See <a href="/pulsatile-tinnitus/">pulsatile tinnitus</a>, and do not treat it with a supplement.

5. New severe vertigo, or a sudden change in balance. Dizziness alongside a new ear sound points towards the inner ear rather than towards a self-directed experiment.

6. Facial weakness, numbness, or any other new neurological symptom. This needs a clinician, promptly, and it is not a supplement question at all.

7. A new sound that started after a new medicine, and stops when the course stops. Do not change the prescription yourself. Take the timing to a prescriber or pharmacist instead.

8. Tinnitus that is worsening steadily rather than staying level. A gradual change is worth assessing so that a baseline audiogram exists to compare against.
