Understanding the causes of age-related hearing loss
Age-related hearing loss (presbycusis) develops gradually for many people. It’s a common part of ageing, but the rate and severity vary widely. For supplement options see our Audifort review for supplement options see our Audifort review. Below I explain the main causes, how they interact, and practical steps you can take to help protect your hearing.
How hearing normally changes with age
Hearing relies on a chain of parts: the outer ear collects sound, the middle ear transmits vibrations, and the inner ear converts those vibrations into nerve signals for the brain. With age, changes can occur at several points in this system — particularly in the tiny hair cells of the inner ear (cochlea) and the auditory nerve pathways in the brain — which can reduce the ability to hear high-pitched sounds and follow speech in noisy places.
Main causes of age-related hearing loss
- Accumulated noise damage: Years of exposure to loud noise (work, leisure, music) damages hair cells in the cochlea. This damage is usually irreversible and contributes strongly to later-life hearing difficulties.
- Genetics: Family history affects susceptibility. Some people inherit inner-ear structures that are more vulnerable to age-related changes.
- Circulatory and metabolic health: Conditions that affect blood flow (high blood pressure, atherosclerosis) or metabolism (diabetes) can impair the tiny blood vessels and nerves that support hearing.
- Long-term ear infections or middle-ear problems: Chronic ear disease or recurrent infections earlier in life can leave residual damage that becomes more noticeable with ageing.
- Ototoxic drugs and chemicals: Certain medications and industrial substances can damage hearing over time. Always discuss medication risks with a clinician or pharmacist.
- Noise from medicines and illness: Some acute illnesses and treatments (e.g. certain antibiotics, chemotherapy agents) can have ototoxic effects — sometimes adding to cumulative age-related decline.
- Neurological changes: Age-related changes in the auditory pathways of the brain can affect how we process and make sense of sound, beyond what the ear itself detects.
Practical prevention and management tips
While not all age-related hearing loss can be prevented, several practical steps reduce risk and help maintain hearing function for longer.
1. Protect your ears from loud noise
Limiting exposure to loud environments is one of the most effective measures. Use ear protection (foam plugs or earmuffs) at noisy events, keep personal audio devices at a lower volume, and take regular quiet breaks if you’re exposed to sound for long periods.
2. Keep cardiovascular and metabolic health in check
Good general health supports the tiny blood supply that nourishes the inner ear. Regular exercise, a balanced diet, and control of conditions such as high blood pressure, high cholesterol and diabetes can all contribute to healthier hearing pathways.
3. Review medications and workplace exposures
Ask your GP or pharmacist whether any medicines you take are known to affect hearing and whether alternatives are available. If you work with potentially ototoxic chemicals or loud machinery, follow workplace safety guidance and use the required protective equipment.
4. Have regular hearing checks
Older adults should consider periodic hearing assessments, especially if they notice difficulty following conversations, frequent requests to repeat, or ringing in the ears (tinnitus). Early detection makes it easier to manage changes and to consider options such as hearing aids, communication strategies and environmental adjustments.
5. Reduce earwax buildup safely
Excessive earwax can temporarily reduce hearing. Avoid using cotton buds, which can push wax deeper. See your GP or a trained practitioner for safe removal if you suspect blockage.
6. Lifestyle habits that support brain and ear health
Smoking cessation, keeping cognitively and socially active, and managing stress contribute to overall brain health and may indirectly support auditory processing.
Supplements and marketed products
A growing number of supplements are marketed as supporting ear health. For example, the makers of Audifort market it as a natural formula containing a blend of herbs and nutrients that they say supports hearing and cognitive clarity. Such products often include antioxidants and botanicals reported to support circulation and inflammation.
Important: manufacturers’ claims about supplements are not the same as medical proof. If you’re considering a supplement, discuss it with your GP, especially if you take medicines or have underlying health conditions. Check for transparent ingredient lists, independent quality checks and realistic promises.

When to seek professional help
See your GP or an audiologist if you experience sudden hearing loss, ongoing deterioration, severe tinnitus, dizziness with hearing changes, or if hearing loss affects your daily life. A professional assessment can identify treatable causes, guide hearing-aid trials and recommend communication strategies or referrals.
Age-related hearing loss is often multifactorial. While you can’t change your genetics or completely reverse inner-ear cell loss, many modifiable factors — noise exposure, cardiovascular health and medication choices — can be managed to help preserve hearing. Regular checks and practical adjustments make a significant difference to quality of life.
