Hearing Loss (Presbycusis)

Presbycusis, or age-related hearing loss, develops gradually in both ears and affects about one in three adults over 65. Hearing aids and other treatments can restore communication and quality of life.

ENT
Age-related hearing loss, known medically as presbycusis, is the gradual decline in hearing that occurs in most people as they grow older. It typically affects both ears equally, and about one in three adults over age 65 has hearing loss significant enough to affect daily life. In a community with as many active retirees as St. Petersburg, it is one of the most common concerns we evaluate — and one of the most undertreated, even though good solutions exist. Because the change happens so slowly, many people adapt without realizing how much sound they are missing. Causes: Presbycusis results from wear on the delicate structures of the inner ear over a lifetime:
  • Aging of the inner ear: The tiny hair cells that convert sound into nerve signals gradually die off and do not regrow.
  • Cumulative noise exposure: Decades of loud work environments, machinery, concerts, or firearms accelerate the damage.
  • Medical conditions: Diabetes and high blood pressure can impair the small blood vessels that nourish the inner ear.
  • Ototoxic medications: Certain antibiotics, chemotherapy drugs, and long-term high-dose aspirin can injure hearing.
  • Earwax buildup: A common, fully reversible contributor that a simple office visit can fix.
Symptoms: Because the change is gradual, family members often notice it first:
  • Muffled speech: Voices sound mumbled, especially women's and children's higher-pitched voices.
  • Trouble in background noise: Restaurants and gatherings become exhausting to follow.
  • Frequent repetition: Asking people to repeat themselves, or turning the television up louder than others prefer.
  • Ringing in the ears: Tinnitus commonly accompanies age-related hearing loss.
  • Withdrawal from conversation: Skipping phone calls or social events because listening has become tiring is often an early clue.
Diagnosis: Your physician will examine your ears to rule out wax blockage or infection, review medications, and refer you for an audiogram — a painless hearing test that maps which pitches and volumes you can hear. The pattern of the results distinguishes presbycusis from other causes and guides treatment, and testing is typically repeated every few years to track any change over time. Treatment: Hearing loss from aging cannot be reversed, but it can be managed very effectively:
  • Hearing aids: Modern devices are small, effective, and now available over the counter for mild to moderate loss; prescription fitting helps with more advanced loss, and an audiologist can fine-tune devices over several visits as the brain re-adapts to sound.
  • Assistive devices: Amplified phones, TV streamers, and captioning apps fill specific gaps.
  • Cochlear implants: An option for severe loss when hearing aids no longer help.
  • Protecting what remains: Earplugs or earmuffs around loud noise slow further decline.
Why Treatment Matters: Untreated hearing loss is linked to social isolation, depression, more falls, and a higher risk of cognitive decline and Alzheimer's disease. Treating hearing loss keeps you connected and protects overall health — it is far more than a convenience. Hearing is also part of everyday safety and awareness: untreated loss makes it harder to notice approaching cars, alarms, and doorbells. One important exception to the "gradual" rule: sudden hearing loss in one ear, developing over hours to a few days, is a medical urgency that needs evaluation right away, because prompt treatment can sometimes restore hearing. If conversations have become hard work, a hearing evaluation is a simple place to start.
