Tinnitus estimates vary, but may occur in 10%-15% of the population

If hearing is damaged, the brain may amplify remaining sounds, perhaps causing tinnitus.

One decibel of hearing loss increases tinnitus risk by 6% for older people

That's according to an analysis of more than 18,000 people published in BMC Medicine in 2023. The tinnitus risk is not just limited to older people: The research also concluded that one decibel of hearing loss increases the risk of developing tinnitus among young adults by 3 percent.

People with tinnitus should avoid silence—sound-rich environments distract the brain

This podcast from an audiologist discusses common questions about tinnitus. It notes that tinnitus could be described as a phantom sound associated with hyperactivity in the brain. It's linked with loud sound exposures above 85 decibels, hearing loss associated with aging and stress, among other factors.

Musicians are 57% more likely to have tinnitus compared to the general public

Musicians have four times the risk of developing hearing loss, and their risk of developing tinnitus is increased by more than half.

Tinnitus is a rare side effect of COVID-19

The infection can affect inner ear cells, and a review of the literature across multiple studies concluded that hearing loss occurred in 3.1% of patients with the virus and tinnitus in 4.5%.

Watch how your nervous system's efforts to process silence can contribute to tinnitus

Cochlear cells can be damaged in numerous ways, including aging or exposure to loud noise. If enough cells die, the auditory system can become less sensitive, prompting the brain to compensate by amplifying sound, which is likely to contribute to tinnitus.

Some men may be at elevated risk of inheriting tinnitus

A 2017 Swedish Twin Registry study suggests that bilateral tinnitus—when tinnitus occurs in both ears instead of just one—appears to be heritable, at least in men.

Tinnitus is the most common compensated claim for US veterans

Since 2003, tinnitus has been the top-ranked compensated claim among US veterans. In 2024 alone, there were more than 3.2 million awards for tinnitus. (Some users may encounter a paywall.)

There's no cure for tinnitus, but sometimes it goes away on its own

Though there's no cure, treatments and management approaches can significantly reduce symptoms and improve quality of life. Hearing aids, sound generators, and other steps can help some people with this condition. But sometimes tinnitus resolves within hours or days for reasons that remain unclear.

More than 5% of the world's population has disabling hearing loss

Disabling hearing loss is defined as hearing loss greater than 35 decibels in the better hearing ear. (For context, that means the sound of leaves rustling, at roughly 30 decibels, would be inaudible even to your better-hearing ear.) The World Health Organization's data suggests that more than 5% of the world's population has this level of loss requiring rehabilitation, which amounts to 430 million people—including 34 million children.

Mapping hearing loss in the US

Nearly 10% of Americans suffer from some degree of hearing loss, measured as the inability to hear sounds lower than 25 decibels. The incidence of hearing loss increases with age and is typically higher among men. Recent analysis produced a puzzling observation researchers can't quite explain: There's a larger incidence of hearing loss among rural populations than in urban centers. Explore the data with this map and explainer.

Ludwig van Beethoven suffered from tinnitus

Historical figures that reportedly had the condition include Charles Darwin and Beethoven. Both men wrote letters about the frustrations and pain they experienced from the condition. (Some users may experience a paywall.)

See worldwide hearing loss by age group and country

This 2023 data from the Institute for Health Metrics and Evaluation shows the estimated number of people with complete hearing loss in different age groups per 100,000 people in the population. Individuals aged 70 or older make up the largest group with this type of hearing deficit.

Beethoven's correspondence in 1801 documented his tinnitus suffering

Ludwig van Beethoven's hearing loss is one of the best-known cases of this condition among historical artists. He also suffered from tinnitus and wrote in 1801, "My ears are buzzing and ringing perpetually, day and night. I can with truth say that my life is very wretched…"

Hearing loss can affect balance and make falls more likely

For reasons that are not yet fully understood, hearing loss seems to increase the risk of falls. One explanation is that reduced environmental awareness due to hearing loss may put people at greater risk. Another theory is that the brain has to work harder to process sound with hearing loss and that cognitive load may also boost the chances of falls. One study found that for every 10 decibel increase in hearing loss, there was a 1.4 fold increased odds of falling in the preceding 12 months.

Pulsatile tinnitus is when you hear thumping synchronized with your heartbeat

This rare type of tinnitus, which sounds like rhythmic thumping or whooshing, is often linked to blood vessel conditions or high blood pressure. Lowering blood pressure through exercise and food choices can help reduce the severity of this condition.

Notch music therapy may filter out some tinnitus frequencies

Researchers in Germany have developed a smartphone app-based therapy for individuals with tinnitus associated with hearing loss. Some people with tinnitus can use this Notch app with their hearing aids to at least partially block sound frequencies matching their tinnitus pitch—turning down the volume of their tinnitus.

Certain medications can make tinnitus worse

Certain antidepressants, antimalarial medications, antibiotics, ibuprofen, and cancer drugs have been linked with the condition. At higher doses, particularly, it seems they can trigger or worsen tinnitus in some individuals.

Age-related hearing loss, known as presbycusis, is a top cause of hearing loss

This video walks through the biology of why presbycusis (prez-buh-kyoo-sis) occurs and its etiology. This type of hearing loss is gradual and typically starts with reductions in the ability to hear high-pitched sounds.

Tinnitus is derived from the Latin verb tinnire, meaning to ring

Read the entry in The Physical Dictionary by Stephen Blankaart, from 1693, where the word first appeared in English.

A novel tinnitus therapy, called Lenire, involves mild electric tongue shocks and sound exposures.

Read Charles Darwin's description of his tinnitus suffering

When he was 57 years old, Darwin wrote to a new doctor about his suffering from a variety of maladies, including "singing of ears", vomiting, recurring flatulence, vomiting, and more. He noted how he believed his stress contributed to these symptoms.

More than 90% of American deaf children are born to hearing parents

The National Institute on Deafness and Other Communication Disorders have collated top statistics about hearing loss in the US including differences by age, racial groups, and other factors.

China reports the highest prevalence of hearing loss and South Africa reports the lowest

This conclusion comes from research published in 2025 that analyzed self-reported hearing loss and hearing aid use from long-term studies that covered 28 countries. Its findings included that the countries with the greatest prevalence of hearing loss (China, South Korea, Mexico, and Brazil) also had the lowest levels of hearing aid use.

See this graphic describing what different decibel levels mean for hearing loss.

Hearing loss is linked with brain volume reductions

The brain looks different as a result of hearing loss, with reductions in brain volume overall and in specific areas, and these changes are hypothesized to impact cognition. Exactly why hearing loss alters cognition is an active area of research, but theories include that the elevated cognitive load of straining to hear affects brain power available for thinking and memory and that hearing loss leads to social isolation which boosts dementia risk.

Ancient Egyptian papyrus from 16th century BCE seems to reference tinnitus

Ancient Egyptians wrote that they treated "bewitched ear" with herbal concoctions that involved frankincense and other ingredients, which were placed in the ear.

See what loud noises do to inner ear hair cells

This animation illustrates how louder music can affect inner ear hair cells. Damage to these cells is generally considered permanent. Hearing protection like ear plugs can reduce the level of sound entering into the ear and help protect those cells.

Untreated hearing loss is linked with dementia risk

Hearing loss does not cause dementia, but it does increase the risk of developing dementia and research suggests that people who wear hearing aids for age-related hearing loss also maintain better brain function than those who don't.

An ear doctor with hearing loss seeks to help those with hearing loss enjoy music

Alex Chern, an ear doctor who has hearing loss himself, dreams of restoring the ability to experience "all the richness and the beauty of the sound of music" for patients—not just functional hearing. Hearing aids amplify sound waves and aren't designed to work well with music that may have varied pitch and volume. Chern is studying how hearing loss and engaging with music may affect cognitive decline.

Cochlear implants are raising questions about deaf identity and culture

The rise of cochlear implants, which are usually covered by insurance and can enable hearing for many patients, raises questions about what it means to be deaf, the effects on deaf individuals learning American Sign Language, and about deaf culture. Watch this video that discusses the controversies and spotlights a little girl who hears for the first time with her cochlear implant.

Individuals with synesthesia experience involuntarily overlapping sensations

Tasting words or seeing colors in music results from the brain retaining extrasensory connections from infancy. While most lose these neural pathways during development, about 4% of people are synesthetes, maintaining them without realizing it's unusual.

A cochlear implant stimulates parts of the cochlea directly, with limited pitch and timbre capabilities

People with these devices have to learn or relearn how to train their brains to interpret nerve signals as sound. The range of the type of sounds that the brain can distinguish with a cochlear implant is limited and consequently it's difficult to understand a tonal language or distinguish individual speakers in a crowd.

About 10%-15% of people experience chronic insomnia

How often would you say you struggle to stay or fall asleep? If it's more than three times per week (and has been going on for at least one month), then you might have one of the most common sleep disorders: insomnia.

Misfired motor signals may explain why many people with schizophrenia hear voices

Up to 80% of schizophrenia patients may have auditory hallucinations. Recent research concluded that this symptom may be from misfired motor signals that feed into each other, essentially failing to suppress certain sensory neural activities and that resulting overexcitment fuels hallucinations. The finding suggests that, one day, magnetic pulses might be used to stimulate specific nerves to better regulate the errant signals and reduce or stop hallucinations. (Some users may encounter a paywall.)

Gene therapy for a rare type of deafness is allowing deaf children and adults to hear for the first time, according to research results reported in April 2026.

OTC hearing aids are now available in the US and cheaper than prescription ones

The devices, available in recent years, are typically more affordable than prescription ones and are intended for people with mild to moderate hearing loss, yet surveys suggest people often don't feel comfortable choosing one on their own. The nonprofit Consumer Reports ranked available OTC options to help patients navigate the market.

Autoimmune diseases affect between 5% and 10% of people worldwide, but their causes remain unknown

Autoantibodies—which attack the body—may be detectable in the body years before a patient develops symptoms, but some people may have detectable levels yet never go on to develop an autoimmune disease. This video discusses this and other unsolved mysteries with autoimmune disease.

Gene therapy is restoring hearing among kids with genetic deafness

Gene therapy for profound genetic deafness has been advancing in recent years, with multiple clinical trials enabling hearing at normal levels for the first time without hearing aids or cochlear implants. The therapies target hearing loss caused by mutations in the OTOF gene that codes for a protein called otoferlin. That protein normally plays a key role in relaying sound signals in synaptic transmission between the ear's inner hair cells and the auditory nerve.

How hearing protection became cool

In recent years, the WHO shared research findings that over 1 billion teens and young people face risks of hearing loss due to unsafe listening practices. While earplugs used to hold a reputation for being uncool, this article explores how awareness has led to more people fashioning different types of hearing protection. Explore the growing trend of earplugs at raves, concerts, and other loud events.

When common sounds become disturbing

Misophonia causes certain sounds to feel violating, triggering a "very visceral kind of experience" filled with extremely unpleasant emotions, including annoyance, anger, and disgust. A 2017 study found that people with misophonia have elevated activity in the brain's anterior insula—a region associated with interoception, emotional processing, and behavioral responses—when exposed to trigger sounds. Ongoing research suggests trigger sound context affects the severity and manifestation of the condition.

Vertigo is two to three times more common in women than men

Dizziness, including vertigo, occurs among 15% to 20% of adults. Vertigo can have numerous causes, but generally it's more common with age. It's also much more common among women than in men—occuring roughly two to three times more frequently, sometimes potentially related to the hormonal fluctuations of menopause or to migraines.

We hear because soundwaves are converted into electrochemical signals in our ears

This science teacher video systematically walks through the biology of the outer, middle, and inner ear. The explanation starts with the auricle, an external part that funnels sound through the auditory canal, and the tympanic membrane (the ear drum), which vibrates when sounds hit it. Beyond that, as the video details, is the eustachian tube, which is connected to the back of our throats and allows air to pass in and out to equalize ear pressure.

Learn about swimmer's ear, which sickens 1 in 10 Americans

This outer ear infection—in the tube leading from the ear opening to the eardrum—is usually caused by bacteria. Formally called otitis externa, this condition is commonly called swimmer's ear because microbes can enter the ear canal while swimming.

736,900 cochlear implants had been implanted by 2020 worldwide

In the United States, roughly 118,100 devices had been implanted in adults by that point and 65,000 in children. These estimated figures come from the US Food and Drug Administration, which first approved cochlear implants for adults experiencing hearing loss in the mid-1980s, and collected reports from cochlear implant manufacturers approved for the US market.

Tornadoes produce inaudible signals to humans hours before forming

Researchers at the National Oceanic and Atmospheric Administration have found that tornado-producing storms generate specific sounds below the range of human hearing, much like the infrasonic signals produced by earthquakes and avalanches. Although difficult to distinguish from wind noise, scientists hope to build systems that use these signals to improve tornado forecasting.

Chronic exposure to traffic noise is associated with a higher risk of Parkinson's disease.

The three smallest bones in the human body—the malleus, incus, and stapes—amplify the vibrations of sound waves by almost 20 times to help enable hearing.

Cochlear implants stimulate nerves inside the ear to provide the sensation of sound

In a surgical procedure, one part of the implant is placed under the skin behind the ear and electrodes are threaded into the cochlea in the inner ear. Another part of the implant sits behind the ear and picks up sound and then converts it into patterns of nerve stimulation.
