Learn the most recent statistics about hearing loss to date.

Key Statistics

Our hearing ability can greatly impact our health. And hearing loss is a common and widespread issue worldwide.

Did you know 1.5 billion people—20% of the world’s population—have some degree of hearing loss? [6]World Report on Hearing. World Health Organization. 2021. Found on the internet at https://apps.who.int/iris/rest/bitstreams/1334317/retrieve It’s currently the third-leading chronic health condition in the United States and cases are rapidly increasing. [7]Centers for Disease Control and Prevention. Loud Noise Can Cause Hearing Loss. Found on the internet at https://www.cdc.gov/nceh/hearing_loss/public_health_scientific_info.html Fortunately, half of all global cases are preventable through public education, early identification, and timely treatment. [6]World Report on Hearing. World Health Organization. 2021. Found on the internet at https://apps.who.int/iris/rest/bitstreams/1334317/retrieve

In order to understand the true scope of the issue, our Reviews Team dug into the latest research to help you protect your hearing and address suspected hearing loss.

Hearing loss facts

Hearing loss is unique to everyone and can occur at any age, although some types, causes, and symptoms are more common than others.

Types of hearing loss

The three primary types of hearing loss are conductive, sensorineural, and mixed hearing loss.

Hearing loss can affect one (unilateral) or both ears (bilateral), and severity ranges from mild to profound. In the United States,

According to the World Health Organization (WHO) 2021 World Report on Hearing, 1.16 billion of the 1.50 billion people who have hearing loss have mild severity. Those with profound or complete hearing loss have the lowest prevalence rates at 0.2%, although both levels still account for a large number of people (29.8 million). [6]World Report on Hearing. World Health Organization. 2021. Found on the internet at https://apps.who.int/iris/rest/bitstreams/1334317/retrieve  See Table 1 for a complete breakdown of hearing loss prevalence by severity level.

Signs and symptoms of hearing loss

People experience hearing loss differently, depending on the type and severity. American Speech-Language-Hearing Association (ASHA) highlights common signs and symptoms, including: [9]Hearing Loss in Adults. American Speech-Language-Hearing Association. Found on the internet at https://www.asha.org/practice-portal/clinical-topics/hearing-loss/

Tinnitus statistics

Ringing in the ears, known as tinnitus, is a type of hidden hearing loss symptom that can indicate auditory damage, often without a clinically significant difference in hearing. The most common cause of tinnitus is excessive noise exposure. [10]Zheng, Yunfang and Guan, Jianwei. Cochlear Synaptopathy: A Review of Hidden Hearing Loss. Journal of Otorhinolaryngology Disorders Treatments. March 2018. Found on the internet at https://sciforschenonline.org/journals/otorhinolaryngology-disorders-treatments/article-data/JODT-1-105/JODT-1-105.pdf According to research:

Causes of hearing loss

Sensorineural and conductive hearing loss have different causes, and mixed hearing loss is a combination of the two.

SNHL is caused by damage to the inner ear and auditory, or cochlear, nerve. As sound waves enter the ear, nerves in the inner ear convert the incoming sound wave vibrations into electrical signals, which are then carried by the auditory nerve to the brain to be translated into sounds. Damage can be caused by: [11]Sensorineural Hearing Loss. American Speech-Language-Hearing Association. Found on the internet at https://www.asha.org/public/hearing/sensorineural-hearing-loss/

According to the Centers for Disease Control (CDC), 50% of people age 12–35 years are at risk of hearing loss due to excessive sound exposure in recreational settings. [7]Centers for Disease Control and Prevention. Loud Noise Can Cause Hearing Loss. Found on the internet at https://www.cdc.gov/nceh/hearing_loss/public_health_scientific_info.html

Age-related hearing loss is a form of SNHL, often caused by degeneration of the inner ear’s structures over time, although additional damage due to noise, injury, health conditions, or certain medications can accelerate and worsen symptoms.

Conductive hearing loss is caused when sound signals can’t travel through the outer and middle part of the ear and is often treatable or reversible with medication or surgery. Sound obstruction can be caused by: [14]Conductive Hearing Loss. American Speech-Language-Hearing Association.

Meniere’s disease statistics

Meniere’s disease is a condition known to cause SNHL, vertigo, and imbalance. Although the condition is rare, Meniere’s disease can have lasting effects on hearing, and episodes of vertigo can drastically affect people’s day-to-day lives by limiting mobility and independence. The most updated review we have found reported the following statistics: [16]Wright, Tony. Meniere’s Disease. BMJ Clinical Evidence. November 2015. Found on the internet at https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4636025/

The cost of hearing loss

Hearing loss has major economic implications worldwide. According to a recent article published in 2021:

In the United States, health care costs associated with hearing loss are also high, particularly among those who go untreated. This is because untreated hearing loss is associated with higher rates of emergency department visits, hospital readmission, and longer hospital stays.

One study showed people with untreated hearing loss cost an average of $22,434 more than people without hearing loss over a 10 year period. [18]Reed, Nicholas S., et al. Trends in Health Care Costs and Utilization Associated With Untreated Hearing Loss Over 10 Years. Journal of the American Medical Association. January 2019. Found on the internet at https://jamanetwork.com/journals/jamaotolaryngology/article-abstract/2714049 Consider that more than 44 million American adults have hearing loss and only one in six Americans with hearing loss between ages 20–69 wear hearing aids (plus 30% of Americans age 70 and older). [5]National Institute on Deafness and Other Communication Disorders. Quick Statistics About Hearing Loss. March 25, 2021. Found on the internet at https://www.nidcd.nih.gov/health/statistics/quick-statistics-hearing

Fortunately, over-the-counter hearing aids are now available in the United States, making it easier for people to access and afford proper treatment for mild to moderate hearing loss.

Hearing loss is on the rise

According to research, the number of Americans with hearing loss is expected to increase from nearly 44.1 million adults in 2020 to 73.5 million by 2060. Projected rates of increased hearing loss by age are also concerning, as some hearing loss is estimated to rise by more than 150% in some age groups. [2]Goman, Adele M., et al. Addressing Estimated Hearing Loss in Adults in 2060. JAMA – Otolaryngology Head & Neck Surgery. July 2017. Found on the internet at https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5824202/

Globally, the WHO reported that 430 million people have at least moderate hearing loss and may benefit from a hearing aid, of which 34 million are children. By 2050, this number will rise to more than 700 million people.

The number of people with any degree of hearing loss is projected to increase from 1.5 billion to nearly 2.5 billion by 2050, according to the WHO. [19]Deafness and hearing loss. World Health Organization. February 2023. Found on the internet at https://www.who.int/health-topics/hearing-loss

Profound hearing loss and deafness statistics

The WHO defines deafness as having profound or total hearing loss, which means they have little to no ability to hear. Many who live with deafness use sign language to communicate.

Average hearing loss by age

Currently, 55.4% of American adults with hearing loss are 70 years and older. Projections show this number will increase to 67.4% in the next four decades. Looking closer at specific age ranges in Tables 2 and 3, we can see more than a 156% projected increase in mild to complete hearing loss in those age 80 and above. [2]Goman, Adele M., et al.

Hearing loss prevalence by state

The (CDC) released a report documenting hearing loss prevalence across all U.S. states and the District of Columbia between 2014 and 2016 (see Table 4). Most states (66%) had a prevalence that met or exceeded the national average of 15.9%. [22]Blackwell, DL and Norris, T.

Hearing Loss Around The World

Nearly 430 million people globally have at least moderate hearing loss and would greatly benefit from a hearing aid.

The World Report on Hearing showed the Western Pacific region (including Australia, China, Japan, and New Zealand) accounted for 136.5 million people—the highest contribution of any region—with a 7.1% prevalence (see Table 5). North and South America accounted for 62.7 million people with a 6.2% prevalence. The U.S. national average prevalence rate of 15.9% is more than double the prevalence rate of the Western Pacific region. [6]World Report on Hearing. World Health Organization. 2021.

The report also showed that hearing loss prevalence among the same 430 million people differed between income groups. Upper middle- and high-income groups had the highest prevalence at 6.2% and 7.5%, respectively (see Table 6). But of the $980 billion cost of unaddressed hearing loss, 53% came from low- and middle-income countries. [6]World Report on Hearing. World Health Organization. 2021.

Gender and hearing loss

Gender analyses on hearing loss historically use a gender binary to report data.

The World Report on Hearing stated that among nearly 430 million people with moderate hearing loss or greater, males had a slightly higher prevalence than females. About 217 million males and 211 million females had at least moderate hearing loss at a 5.6% and 5.5% prevalence rate, respectively. [6] World Report on Hearing. World Health Organization. 2021. Found on the internet at https://apps.who.int/iris/rest/bitstreams/1334317/retrieve

The CDC reported an even larger prevalence gap of 22.7% between American male and female adults. In 2022, 17.6 million males age 18 and older reported some degree of hearing loss, while 13.6 million females reported the same.[1] According to a CDC National Health Interview Survey, only 7.1% of adults age 45 and older have used a hearing aid, with usage higher among men than women.

The impact of hearing loss

Unaddressed hearing loss has a significant impact on communication, learning, employment, and overall health across all ages.

Hearing loss and educational outcomes

In children, unaddressed hearing loss can affect the ability to learn communication skills, subsequently affecting academic progression and career planning into adulthood. [24]Yong, Michael, et al. How the World’s Children Hear: A Narrative Review of School Hearing Screening Programs Globally. OTO Open. May 2020. Found on the internet at https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7238315/ Early detection and treatment, ideally before the age of six months, are essential in preventing developmental issues.

Found on the internet at https://pubmed.ncbi.nlm.nih.gov/9893323/

Similarly, American adults with unaddressed hearing loss achieve less education and have higher unemployment rates than those with unaffected hearing. People with unaddressed hearing loss are half as likely to achieve higher education, and those who are employed historically earn lower wages. [26]Jung, David and Bhattacharyya, Neil.

Hearing loss and health outcomes

Hearing loss has a large impact on mental and emotional health. Studies have found that those with varying degrees of unaddressed hearing loss experienced higher rates of social isolation, loneliness, depression, and anxiety.

Comparing research to clinical practice

Our Reviews Team asked Ruth Reisman, audiologist and co-founder of Urban Hearing in Brooklyn, New York, about her take on these statistics.

When we asked her about the expected rise in hearing loss cases, she responded, “As far as my private practices are concerned, my schedule is typically full, but I don’t believe the volume has increased any more than it’s been in the past.”

In a recent conversation with a colleague, she exchanged thoughts on how shocking it is that more people aren’t caring for their hearing in the same way teeth and eyes are cared for. “This may be because there is insufficient education or awareness surrounding hearing loss and its effects on the person’s quality of life,” Reisman said. “Oftentimes, people don’t believe it’s important enough until they lose their hearing.”

Regular visits to an audiologist could help catch reversible causes of hearing loss. Reisman estimated that 50% of the patients who visit her clinic for suspected hearing loss actually had the conductive type and just needed to address clogged ears, like excess ear wax. The other 50% included sensorineural hearing loss that would benefit from a hearing aid. Mixed hearing loss was not common in her practice, she said.

Consistent with research, Reisman said most of her patients have mild to moderate hearing loss. But most of these people are young- to middle-aged. Unfortunately, younger adults are more likely to be evaluated than older adults. “The reason is likely due to the fact they feel it’s affecting their quality of life,” she said, whether they’re having challenges hearing in various environments, or due to their active lifestyles. “And when told they have a mild hearing loss, they don’t necessarily take the next steps to treat the hearing loss.”

The health consequences of untreated hearing loss are apparent in clinical practice. Reisman told us that people with hearing loss have expressed feelings of isolation and challenges communicating with family members. “Some people also feel they need to stop working due to the challenges they experience. This can affect self-esteem and identity, which leads to potential depressive symptoms.”

Hearing loss prevention

According to the WHO, up to 50% of hearing loss can be prevented through lifestyle changes and public health initiatives. The monetary government investment, while steep, can be rewarding. An estimated $16 return can be expected for every dollar invested in hearing care services over a 10 year period. The WHO highlights key ways to prevent new cases or mitigate severity: [6]World Report on Hearing. World Health Organization. 2021. Found on the internet at https://apps.who.int/iris/rest/bitstreams/1334317/retrieve [19]Deafness and hearing loss. World Health Organization. February 2023. Found on the internet at https://www.who.int/health-topics/hearing-loss

Reisman shared the advice she gives to patients trying to prevent hearing loss or worsening symptoms. “Using generic hearing protection from the pharmacy will help to preserve hearing when exposed to loud noise, like during concerts or in loud work environments.” Her advice holds true for people who already have hearing loss, and who may not notice when noise is loud enough to be harmful. “Those with hearing loss are more susceptible to damage if exposed to loud noise, so they have an even higher obligation to wear hearing protection.”

Visit the Medicare Advocacy Organization and the Hearing Loss Association of America to learn how you can support initiatives that improve access to hearing care nationwide.

Bottom line

The prevalence of hearing loss is increasing rapidly, particularly among older adults. Prevention efforts are vital for protecting the global population from this growing health crisis and its consequential impact on economies, development, communication, and mental health.

If you suspect hearing loss, visit your local audiologist for a full examination. Ask your doctor about your treatment options and, if appropriate, consider buying one of the best hearing aids on the market so you can return to hearing the world as it should be.
