What Are the Risk Factors for Age-Related Hearing Loss?

What Are the Risk Factors for Age-Related Hearing Loss?

The main risk factors for age-related hearing loss include increasing age, genetics, long-term exposure to loud noise, smoking, diabetes, high blood pressure, and certain medications that can damage hearing.

Age-related hearing loss, also called presbycusis, usually develops gradually and affects both ears. Higher-pitched sounds are often affected first, making it difficult to understand speech clearly, particularly in noisy environments.

Some risk factors, such as age and inherited susceptibility, cannot be changed. Others, including hazardous noise exposure and smoking, are potentially modifiable.

The key point: No single factor explains every case of age-related hearing loss. Biological aging, inherited characteristics, medical conditions, and lifetime environmental exposures may all contribute.

Although scientists do not currently know how to prevent presbycusis completely, protecting your ears from hazardous noise and addressing important health risks can support hearing health as you age.

How Common Is Age-Related Hearing Loss?

Age-related hearing loss is one of the most common health conditions affecting older adults.

According to the National Institute on Deafness and Other Communication Disorders (NIDCD):

• Approximately one in three U.S. adults ages 65 to 74 has hearing loss.
• Nearly half of adults older than 75 have difficulty hearing.

These estimates describe hearing loss among older adults and do not mean that every case is caused exclusively by biological aging.

Noise exposure, genetic susceptibility, and other health conditions can contribute to hearing difficulties within these age groups.

Which Risk Factors for Age-Related Hearing Loss Can You Change?

Risk factors are often divided into nonmodifiable factors, which cannot be changed, and modifiable factors, which people may be able to reduce or manage.

Some medical factors, such as diabetes and high blood pressure, can be managed but not necessarily eliminated.

Importantly, reducing a risk factor does not guarantee that age-related hearing loss will be prevented.

1. Increasing Age

Age is the strongest and most consistent risk factor for presbycusis.

As people grow older, changes can occur throughout the hearing system, including the cochlea, auditory nerve, and pathways involved in interpreting sound.

These biological changes may reduce hearing sensitivity and make speech more difficult to understand.

Age-related hearing loss often develops slowly, sometimes over many years.

Why Higher Frequencies Are Often Affected First

Different regions of the cochlea respond most strongly to different sound frequencies.

The region near the base of the cochlea responds to higher-frequency sounds and is vulnerable to several forms of hearing damage.

Age-related changes frequently affect higher frequencies earlier or more severely than lower frequencies.

This may make consonants such as “s” and “f” difficult to hear while lower-pitched parts of speech remain relatively audible.

However, presbycusis does not follow exactly the same pattern in every person.

2. Genetics and Family History

Genetic susceptibility plays an important role in age-related hearing loss.

Some inherited variations may affect the maintenance and function of inner-ear structures or influence how vulnerable the auditory system is to aging and environmental exposures.

A family history of hearing loss can suggest increased susceptibility, although it does not guarantee that someone will develop the same hearing difficulties as their relatives.

People without a family history can also develop presbycusis.

Genetics interacts with other factors, including noise exposure, health conditions, and aging-related biological changes.

For additional information, see MedlinePlus Genetics: Age-Related Hearing Loss.

3. Long-Term Exposure to Loud Noise

Repeated exposure to hazardous noise is an established cause of hearing damage and can contribute to hearing difficulties later in life.

The effects of noise exposure may accumulate over many years.

Common sources include:

• Construction and industrial machinery
• Farm equipment and power tools
• Firearms and explosions
• Concerts and loud entertainment venues
• Motorcycles and other loud engines
• Headphones played at excessive volume

Both the intensity and duration of noise exposure matter.

A single extremely loud sound can damage hearing, while repeated exposure to lower but still hazardous sound levels can also cause permanent changes.

Why Noise Exposure Matters More With Age

Some people reach older adulthood with hearing damage accumulated through years of work, recreational activities, or other noisy environments.

This damage may coexist with the biological changes associated with aging.

As a result, hearing loss in an older adult may reflect several contributors rather than aging alone.

The Centers for Disease Control and Prevention (CDC) explains that noise-induced hearing loss can result from either a single intense exposure or repeated loud sounds over time.

4. Smoking and Tobacco Exposure

Smoking is associated with an increased risk of hearing loss in observational research.

Researchers have investigated possible explanations involving blood circulation, oxidative stress, and exposure to harmful substances in tobacco smoke.

However, observational associations do not establish precisely how much smoking contributes to an individual’s hearing loss.

Secondhand smoke exposure has also been investigated as a possible hearing-health risk.

Avoiding tobacco and quitting smoking have well-established benefits for cardiovascular and overall health.

Whether smoking cessation directly prevents or slows presbycusis in an individual remains uncertain.

5. Diabetes

Diabetes is associated with a greater likelihood of hearing loss.

Researchers have proposed several possible mechanisms, including changes affecting small blood vessels and nerves involved in hearing.

However, not every person with diabetes develops hearing loss, and diabetes does not explain every case of presbycusis.

Managing diabetes remains important for general health and may help reduce some complications associated with the condition.

People with diabetes who notice hearing changes should discuss them with their healthcare professional.

6. High Blood Pressure and Cardiovascular Health

High blood pressure and certain cardiovascular conditions are associated with hearing loss in research studies.

The cochlea depends on a reliable blood supply to support its normal function.

Researchers continue to investigate how vascular health, circulation, and metabolic factors may contribute to age-related hearing difficulties.

However, the relationship is complex, and an association does not establish direct causation in every person.

Managing blood pressure and cardiovascular risk factors is important for overall health, although it has not been proven to prevent presbycusis.

7. Medications That Can Affect Hearing

Some medications can damage structures involved in hearing. These are called ototoxic medications.

Examples include certain chemotherapy medications and specific antibiotics used for serious infections.

Some other medications, including certain pain relievers and diuretics, have also been associated with hearing-related effects under particular circumstances.

The risk depends on factors such as:

• The specific medication
• Dosage and duration of use
• Other medications being taken
• Kidney function and overall health
• Individual susceptibility

Not everyone who uses these medications experiences hearing loss.

Important: Never stop or change a prescribed medication without speaking with the prescribing clinician.

People receiving potentially ototoxic treatments may benefit from hearing monitoring when recommended by their medical team.

Do Risk Factors for Age-Related Hearing Loss Add Up?

Many older adults have more than one hearing-loss risk factor.

For example, someone may have a family history of hearing loss, decades of occupational noise exposure, and diabetes.

These factors can coexist and may influence hearing through different biological mechanisms.

However, it is not possible to calculate an individual’s likelihood of hearing loss simply by counting risk factors.

The interaction between aging, genetics, environmental exposures, and medical conditions remains an active area of research.

Are Age-Related Hearing Loss and Earwax Buildup the Same Thing?

No. Earwax buildup can cause conductive hearing loss by blocking sound from traveling through the ear canal.

Presbycusis generally involves age-related changes in the inner ear and auditory system.

Both can occur in older adults, and they may occur together.

Impacted earwax may be treatable through appropriate professional removal, while permanent sensorineural hearing loss generally cannot be reversed with current standard treatment.

A hearing evaluation can help identify whether a treatable condition is contributing to hearing difficulties.

What Are the Early Signs of Age-Related Hearing Loss?

Age-related hearing loss commonly develops gradually, making early changes easy to overlook.

Possible symptoms include:

• Difficulty following conversations in restaurants or other noisy places
• Frequently asking people to repeat themselves
• Feeling that others are mumbling
• Needing higher television or telephone volume
• Difficulty hearing higher-pitched voices or sounds
• Missing certain speech consonants
• Having trouble following group conversations
• Feeling tired after prolonged listening
• Experiencing tinnitus alongside hearing difficulties

These symptoms are not specific to presbycusis and may occur with other hearing conditions.

Can You Prevent Age-Related Hearing Loss?

There is currently no established method that completely prevents age-related hearing loss.

However, some forms of hearing damage that can occur alongside presbycusis are preventable.

The clearest example is noise-induced hearing loss.

Protect Your Ears From Hazardous Noise

Reducing excessive noise exposure is one of the most effective steps available for preventing avoidable hearing damage.

Practical measures include:

• Use properly fitted hearing protection around hazardous noise.
• Reduce headphone volume when listening at high levels.
• Limit time spent in very loud environments.
• Move farther from loudspeakers when practical.
• Follow workplace noise-safety requirements.
• Choose quieter equipment when feasible.

Hearing protection should be selected for the activity and worn correctly.

Active noise-canceling consumer headphones should not automatically be considered substitutes for certified occupational hearing protection.

Manage Existing Health Conditions

Follow recommended care for diabetes, high blood pressure, and other chronic medical conditions.

Appropriate medical management supports overall health, although it does not guarantee preservation of hearing.

Avoid Smoking

Smoking cessation offers substantial general health benefits.

Because smoking is associated with hearing loss, avoiding tobacco is also a reasonable hearing-health precaution.

However, quitting smoking should not be presented as a proven treatment that restores or prevents age-related hearing loss.

Review Medication Risks When Appropriate

Ask a healthcare professional whether medications you take have known hearing-related risks.

Discuss whether hearing monitoring is appropriate, particularly when receiving treatments associated with ototoxicity.

Never stop prescribed treatment independently.

Does Exercise or Diet Prevent Hearing Loss?

Regular physical activity and a balanced diet support cardiovascular and metabolic health.

Because hearing health is influenced by multiple biological factors, researchers have investigated whether these habits are associated with better hearing outcomes.

However, current evidence does not establish a specific diet, exercise routine, vitamin, or supplement that reliably prevents or reverses presbycusis.

Healthy lifestyle habits remain worthwhile for their established overall health benefits, but they should not be promoted as proven hearing-loss cures.

How Is Age-Related Hearing Loss Diagnosed?

A comprehensive hearing evaluation can measure hearing thresholds and help distinguish presbycusis from other possible causes.

An audiologist typically reviews symptoms, medical history, medications, and noise exposure.

The assessment may include:

• Otoscopy: Examination of the ear canal and eardrum
• Pure-tone audiometry: Measurement of hearing sensitivity at different frequencies
• Speech audiometry: Assessment of spoken-word recognition
• Tympanometry: Evaluation of aspects of middle-ear function
• Speech-in-noise testing: Assessment of communication difficulties with competing sounds, when appropriate

The results help determine the type and severity of hearing loss and whether additional medical assessment is appropriate.

Can Hearing Aids Help With Age-Related Hearing Loss?

Hearing aids can improve access to sound for many people with age-related hearing loss.

Modern hearing aids can provide frequency-specific amplification and may include features such as directional microphones, noise management, and wireless connectivity.

However, hearing aids do not repair damaged inner-ear structures or guarantee normal hearing.

Benefits vary depending on hearing thresholds, speech recognition, device fitting, and listening conditions.

Some people also benefit from remote microphones, television captions, communication training, or other assistive listening technology.

Why Adjustment and Follow-Up Matter

New hearing-aid users may need time to become accustomed to amplified sounds.

Follow-up appointments allow an audiologist to check device performance, adjust settings, and address comfort or communication difficulties.

Learning and adaptation remain possible in later life, partly because the nervous system can change through experience.

This capacity is called neuroplasticity, but it does not guarantee that hearing aids will restore normal speech understanding.

For more background, see our article on what neuroplasticity is and how it works.

Is Hearing Loss Linked to Cognitive Decline?

Research has found associations between hearing loss, cognitive decline, and dementia.

However, these associations do not prove that hearing loss directly causes dementia.

Researchers are investigating possible explanations, including shared health risks, reduced social engagement, and the additional effort required to understand unclear speech.

Studies of hearing interventions have reported mixed findings depending on the population and outcomes examined.

Hearing aids should not be described as a proven way to prevent dementia.

Addressing hearing difficulties remains important for communication and participation in everyday activities.

For additional context, read our article on what normal cognitive aging means.

When Should You Get Your Hearing Checked?

Schedule a professional hearing evaluation when you notice persistent hearing difficulties, changes in speech understanding, or increased difficulty communicating in everyday situations.

People with substantial occupational or recreational noise exposure, certain medical conditions, or potentially ototoxic medication use may need hearing monitoring based on their individual circumstances.

Do not assume that hearing changes are simply a normal consequence of getting older.

Some conditions that cause hearing difficulty are treatable, and identifying them requires appropriate evaluation.

Urgent warning: Sudden hearing loss in one or both ears requires prompt medical evaluation, preferably the same day. Sudden hearing changes should not be attributed to ordinary aging without assessment.

Frequently Asked Questions

What is the biggest risk factor for age-related hearing loss?

Increasing age is the strongest risk factor. However, genetics, cumulative noise exposure, certain medical conditions, smoking, and ototoxic medications may also contribute.

Does everyone develop hearing loss as they age?

No. Hearing loss becomes more common with age, but the degree, timing, and progression vary considerably between individuals.

Does family history increase the risk of presbycusis?

Yes. Genetic susceptibility and family history can influence the likelihood of developing age-related hearing loss. However, having a family history does not guarantee hearing loss, and people without one can still develop the condition.

Can high blood pressure cause hearing loss?

High blood pressure is associated with hearing loss in research studies. However, the relationship is complex, and the presence of high blood pressure does not establish that it caused an individual’s hearing impairment.

Is diabetes a risk factor for hearing loss?

Yes. Diabetes is associated with a greater prevalence of hearing loss. Researchers continue to investigate the mechanisms involved. Appropriate diabetes management remains important for overall health.

Can smoking make age-related hearing loss worse?

Smoking is associated with increased hearing-loss risk in observational studies. However, the degree to which it changes the progression of presbycusis in an individual is uncertain.

Does loud music increase hearing-loss risk later in life?

Yes. Repeated exposure to loud music can cause noise-induced hearing damage, which may contribute to hearing difficulties as a person gets older.

Can age-related hearing loss be reversed?

Permanent sensorineural hearing loss generally cannot be reversed with current standard medical treatment. However, hearing aids and other interventions may improve communication, and some other causes of hearing problems are treatable.

Do vitamins or supplements prevent hearing loss?

No vitamin or supplement has been established as a reliable way to prevent or reverse age-related hearing loss. Supplements should not be used as substitutes for appropriate hearing protection or medical evaluation.

At what age should I get a hearing test?

There is no single age that applies to everyone. Hearing evaluation is appropriate whenever symptoms occur, and monitoring may be recommended earlier for people with significant risk factors. A healthcare professional can help determine a suitable schedule.

The Bottom Line

Age-related hearing loss develops through a combination of biological aging, inherited susceptibility, and other medical and environmental influences.

Major risk factors include increasing age, family history, long-term noise exposure, smoking, diabetes, high blood pressure, and certain medications.

Not all of these factors are preventable, and not every association proves a direct cause.

Protecting your ears from hazardous noise, maintaining appropriate medical care, and obtaining hearing evaluations when concerns arise can help support hearing health as you age.

If you notice changes in hearing, a comprehensive audiological evaluation is the most useful next step toward identifying the cause and understanding your options.
