For roughly a third of people who develop tinnitus after COVID-19, the ringing or buzzing fades entirely, and another third see meaningful improvement, but the remaining third report no change months later. That split comes from one of the more closely tracked cohorts in the literature, and it captures the frustrating reality of COVID-related tinnitus: recovery is common but far from guaranteed. The causes turn out to be more varied than most people assume, involving not just the virus itself but also the drugs used to fight it and the psychological toll of being sick.
How Common Is Tinnitus After COVID-19
The numbers depend heavily on who is being studied and when. A cross-sectional survey of over 1,300 post-COVID patients found that about 28% developed tinnitus symptoms following infection. Of those, roughly a quarter had slight tinnitus, about a fifth had mild symptoms, another fifth had moderate symptoms, and a third fell into the severe category. Around 17% of those reporting tinnitus had experienced it before getting COVID, which means the virus may have worsened an existing condition rather than creating a new one.1PubMed Central. Prevalence and prognosis of tinnitus in post-COVID-19 patients: a cross-sectional survey
In a long-COVID cohort specifically, about 30% of patients reported tinnitus, with nearly a quarter of those rating the severity at 8 or higher on a 10-point scale.2PubMed Central. Self-reported Tinnitus and Vertigo or Dizziness in a Cohort of Adult Long COVID Patients These are not small numbers, though they likely overcount somewhat because the sickest patients are the ones most motivated to fill out questionnaires. One encouraging trend: the share of new tinnitus cases attributed to COVID dropped steadily as the pandemic progressed, falling from about 10% of clinic cases in 2020 to under 5% by 2022 and hitting zero in 2023 and 2024.3PubMed Central. Trajectory of COVID-related tinnitus over the pandemic timeline Whether that reflects milder variants, broader immunity, or better treatment is hard to say, but the trend is real.
Why COVID Can Trigger Tinnitus
There is no single mechanism. The virus appears to have at least three distinct ways of reaching the auditory system, and in any given person, more than one may be involved.
The most direct route is viral invasion of the inner ear itself. Researchers have shown that human inner ear tissue expresses the ACE2 receptor and its cofactors, the same molecular doorway the virus uses to enter lung and nasal cells. In laboratory experiments, hair cells and Schwann cells from human inner ear tissue were infected by SARS-CoV-2.4Communications Medicine. Direct SARS-CoV-2 infection of the human inner ear may underlie COVID-19-associated audiovestibular dysfunction Animal studies have confirmed a similar pattern: the virus entry machinery is present in the organ of Corti, the stria vascularis, and the spiral ganglion cells of the inner ear.5PubMed. Expression of ACE2, TMPRSS2, and Furin in Mouse Ear Tissue, and the Implications for SARS-CoV-2 Infection If the virus damages these structures, the brain can interpret the disrupted signals as phantom sound.
A second pathway involves blood supply. COVID-19 is well known for causing widespread inflammation and clotting problems. The inner ear depends on tiny blood vessels for its oxygen and nutrient supply, and when that microcirculation is disrupted, auditory and balance symptoms can follow.6PubMed Central. Sudden Sensorineural Hearing Loss Post Coronavirus Disease: A Systematic Review of Case Reports This vascular mechanism is probably also why some people develop sudden hearing loss during or shortly after COVID.
The third pathway runs through the brain itself. SARS-CoV-2 can trigger neuroinflammation affecting the brainstem, which processes auditory signals. Brainstem dysfunction from this inflammation can produce a range of sensory deficits, including hearing problems and tinnitus.7PubMed Central. Hearing Loss, Tinnitus, and Dizziness in COVID-19: A Systematic Review and Meta-Analysis Audiological testing of post-COVID patients has found delayed brainstem auditory responses, suggesting the signal processing itself is slower than normal even when the ear looks structurally intact.8PubMed Central. Sensorineural Hearing Loss in Patients with Long-COVID-19: Objective and Behavioral Audiometric Findings
These pathways are not mutually exclusive. A case report of a COVID patient with new tinnitus found that otoacoustic emission testing showed damage to outer hair cells at low frequencies in one ear, meaning the inner ear was physically affected, while other indicators pointed to central processing issues as well.9PubMed Central. Otologic Manifestations COVID-19 and Tinnitus In other words, the virus can hit your ears and your brain at the same time.
What Recovery Actually Looks Like
The most granular recovery data comes from a cohort study that tracked 21 COVID patients who developed tinnitus. Tinnitus typically appeared about a month after initial COVID symptoms. At follow-up, which averaged roughly 8 to 9 months after infection, a third had fully recovered, a third reported reduced symptoms, and a third reported no improvement at all.10European Annals of Otorhinolaryngology, Head and Neck Diseases. Incidence and duration of self-reported hearing loss and tinnitus in a cohort of COVID-19 patients with sudden chemosensory loss That roughly two-thirds-improve figure is more optimistic than the general tinnitus population, where chronic cases tend to persist for years.
A comparative study reinforces this. When researchers compared the severity of post-COVID tinnitus against tinnitus from other causes, the COVID group clustered in the negligible-to-mild range on standard handicap inventories, while the non-COVID group showed higher rates of moderate-to-catastrophic scores. The authors concluded that post-COVID tinnitus tends to produce less discomfort and points toward greater trends in symptom reduction over time.11Audiol., Commun. Res.. Intensity and discomfort of post-COVID-19 tinnitus: a comparative study
A small case series of patients who developed sudden hearing loss alongside tinnitus during mild COVID found that all patients who received prompt treatment saw significant improvement in their tinnitus.12PubMed Central. Sudden Sensorineural Hearing Loss in Mild Covid-19: Case Series and Analysis of the Literature The word “prompt” matters here. Early treatment with corticosteroids appears to make a difference in cases involving sudden hearing loss, and delay may narrow the window for recovery.
One finding that complicates the picture: in a study comparing people who had COVID with those who did not, none of the COVID patients reported any decrease in tinnitus-related distress during the study period, while about 14% of the non-COVID group actually saw their pre-existing tinnitus improve. Among the COVID group, about a quarter reported their tinnitus getting worse.13PubMed Central. Long-Term Effects of COVID-19 and the Pandemic on Tinnitus Patients This suggests that COVID infection may interfere with the natural habituation process that helps many chronic tinnitus sufferers adapt over time.
When the Treatment Causes the Ringing
Here is something that often gets missed: some of the drugs used to treat COVID-19, especially early in the pandemic, are themselves known to cause tinnitus. Chloroquine, hydroxychloroquine, azithromycin, remdesivir, favipiravir, and lopinavir all carry ototoxic potential.14PubMed Central. Don’t forget ototoxicity during the SARS-CoV-2 (Covid-19) pandemic! In some cases, combining these medications could produce additive ototoxic effects, meaning the drugs together were harder on hearing than any single drug alone.15Journal of Hearing Science. Ototoxicity of Drugs Used in the Treatment of COVID-19
This is not just theoretical. A study that tested the high-frequency hearing of patients who received favipiravir, hydroxychloroquine, or both found significant threshold shifts at frequencies above 8 kHz. Standard hearing tests only go up to 8 kHz, so this kind of damage can go completely unnoticed in routine evaluations.16PubMed Central. Impact of COVID-19 Medication (Favipiravir and Hydroxychloroquine) on High Frequency Hearing If you developed tinnitus during or shortly after COVID treatment in 2020 or early 2021, the medications you received are worth discussing with your doctor as a potential contributor. Drug-induced ototoxicity is sometimes reversible once the medication is stopped, though damage from prolonged use may be permanent.
This distinction matters for recovery expectations. Tinnitus from drug ototoxicity follows a different trajectory than tinnitus from viral damage to the inner ear or from neuroinflammation. If the drug was the primary culprit and you are no longer taking it, the prognosis for improvement may be better than if the virus caused structural damage to hair cells, which do not regenerate in humans.
Stress, Anxiety, and the Feedback Loop
The pandemic itself, separate from the virus, made tinnitus worse for many people. A systematic review found that tinnitus severity scores were significantly higher during the pandemic compared to before it, and the increase tracked closely with anxiety levels. The effect of pandemic-related anxiety appeared to directly amplify tinnitus awareness.17PubMed Central. The Impact of COVID-19 and the Pandemic on Tinnitus: A Systematic Review
This creates a vicious cycle that many tinnitus sufferers recognize: you notice the ringing, you feel anxious about it, the anxiety makes the ringing louder or more intrusive, and the louder ringing makes you more anxious. Research on post-acute COVID (sometimes called PASC) has found that tinnitus perception predicts higher cognitive fatigue scores, suggesting the symptom does not exist in isolation but feeds into the broader experience of brain fog and exhaustion that characterizes long COVID.18Scientific Reports. Altered auditory brainstem responses are post-acute sequela of SARS-CoV-2 (PASC)
Breaking that cycle is often where the most accessible gains are. A comparative study of home-based tinnitus treatments during the pandemic found that both tinnitus retraining therapy and mindfulness-based tinnitus stress reduction produced significant improvements in handicap scores and quality of life. The mindfulness approach performed slightly better at reducing tinnitus-related annoyance.19The International Tinnitus Journal. Management of Tinnitus In Covid-19 Outbreak- A Comparative Study Between Mindfulness Based Tinnitus Stress Reduction And Tinnitus Retraining Therapy Neither approach cures the underlying cause, but both help your brain turn down the alarm response to the sound, which often makes the tinnitus feel less severe even if it is still technically present.
Inflammatory Biomarkers and Who Recovers Worst
Not everyone who gets COVID-related hearing symptoms responds equally to treatment. Researchers studying sudden sensorineural hearing loss after COVID found that patients who did not respond well to treatment had significantly higher levels of C-reactive protein (CRP), a common marker of inflammation, along with higher blood pressure and elevated markers of systemic inflammation and clotting activity.20PubMed Central. Clinical utility of inflammatory biomarkers in COVID‐19‐related sudden sensorineural hearing loss
A separate study found that COVID patients had elevated blood levels of prestin, a protein specific to the outer hair cells of the inner ear, and that prestin levels correlated strongly with inflammatory markers like CRP and D-dimer.21PubMed Central. Blood prestin levels in COVID-19 patients Prestin leaking into the bloodstream suggests active damage to the delicate hair cells that convert sound vibrations into electrical signals. These findings hint that if your COVID infection involved intense systemic inflammation, your auditory system may have taken a harder hit and recovery could take longer.
Pre-existing metabolic conditions appear to play a role too. In studies of post-vaccination tinnitus (discussed below), metabolic syndromes were correlated with greater tinnitus severity, and there is no reason to think the virus would be different in this regard. People with poorly controlled blood sugar, high blood pressure, or obesity may face a higher baseline risk of inner ear damage from any inflammatory trigger.
What About the Vaccine
Tinnitus reports following COVID vaccination made headlines and understandably worried people. Analysis of the U.S. Vaccine Adverse Event Reporting System (VAERS) found tinnitus reporting rates of roughly 47 to 70 cases per million full vaccinations across different vaccine brands, with onset often rapid. More women than men reported the symptom, and for two-dose vaccines, tinnitus was more commonly reported after the first dose. About half of people who developed tinnitus after the first dose reported worsening after the second.22PubMed Central. COVID-19 vaccination-related tinnitus is associated with pre-vaccination metabolic disorders
However, when researchers applied formal signal-detection methods to the same data, they did not find disproportionate reporting of tinnitus for any COVID vaccine. A more rigorous analysis using the Vaccine Safety Datalink, which tracks actual medical visits rather than self-reports, found that tinnitus visit rates after COVID vaccination were similar to those after routine influenza vaccination for most age groups. The only exception was adults 65 and older, who showed modestly higher rates after COVID vaccines compared to flu shots.23PubMed Central. Tinnitus after COVID-19 Vaccination: Findings from the Vaccine Adverse Event Reporting System and the Vaccine Safety Datalink The overall conclusion: current evidence does not support a substantially increased risk of tinnitus from COVID vaccination, though researchers have not definitively ruled out a small risk. Getting COVID itself appears to carry a meaningfully higher risk of tinnitus than getting vaccinated against it.
COVID Tinnitus in Children
Adults are not the only ones affected. In a study of children aged 5 to 11, those who had been infected with SARS-CoV-2 had a significantly higher prevalence of tinnitus, as well as sensitivity to loud sounds, ear fullness, and ear pain, compared to children who received the COVID vaccine without infection.24PubMed Central. Audiological and vestibular symptoms following SARS-CoV-2 infection and COVID-19 vaccination in children aged 5-11 years
A study of 192 pediatric COVID patients found that 44 presented with hearing loss, tinnitus, or both. Among the children with tinnitus, the sporadic type was more common than constant ringing, and the average age was around 9 years.25MGM Journal of Medical Sciences. Hearing loss and tinnitus among pediatric patients with COVID-19 infection Children often cannot articulate what they are experiencing as clearly as adults, so tinnitus in younger patients may go underreported. If your child complains of buzzing, hissing, or difficulty hearing after a COVID infection, a pediatric audiological evaluation is worth pursuing.
Did the Variant Matter
There were early assumptions that later, milder variants would produce less tinnitus, and some data supports this. A systematic review examining tinnitus across different SARS-CoV-2 strains found tinnitus prevalence of about 10% during the Alpha/Beta wave, rising to nearly 14% during Delta, and settling at about 12.5% during Omicron.26PubMed Central. Characteristics of Tinnitus in Patients Affected by COVID-19: A Systematic Review The differences are not dramatic, and confounders like vaccination status and treatment protocols changed between waves. The declining share of new COVID-attributable tinnitus cases at clinics over time likely reflects a combination of variant changes, rising population immunity, and evolving treatment rather than any single factor.
The practical takeaway is that no variant was “safe” from an auditory standpoint. The ear involvement was a feature of the virus broadly, not something unique to the original Wuhan strain or to Delta.
Practical Steps If You Are Dealing With This
If you developed tinnitus during or after COVID, a few things are worth knowing. First, get a proper audiological evaluation, ideally one that includes extended high-frequency testing above the standard 8 kHz range. Standard hearing tests may miss the kind of damage COVID and its treatments cause. Brainstem auditory evoked response testing can help determine whether the problem is in your ear, your auditory nerve, or your brainstem processing.
Second, ask about the medications you were given during your COVID treatment. If you received hydroxychloroquine, favipiravir, azithromycin, or similar drugs, especially in combination, your tinnitus may be partly or entirely drug-related, and the trajectory for medication-induced tinnitus can differ from virus-induced damage.
Third, do not underestimate the anxiety component. The evidence clearly shows that pandemic-related stress amplifies tinnitus perception, and breaking that feedback loop is one of the most effective interventions available. Sound therapy, cognitive behavioral therapy, and mindfulness-based approaches all have evidence behind them, and they can be started at home without waiting for a specialist referral.
Fourth, give it time, but set a timeline. Most improvement in post-COVID tinnitus happens within the first year. If you are still experiencing severe symptoms beyond 12 months with no change, that is the point to discuss more aggressive management strategies with an ear, nose, and throat specialist. The evidence suggests COVID-related tinnitus is generally milder and more likely to improve than tinnitus from other causes, but “likely to improve” is not the same as “guaranteed to resolve,” and about a third of people will need ongoing management.
