Age-related hearing loss

Medically known as presbycusis, hearing loss in old age should never be dimissed

If your health care provider has recently told that you have age-related hearing loss (medically known as presbycusis), you’re in good company. Statistics show about one-third of adults between 65 and 70 have some degree of hearing loss, according to the National Institute on Deafness and Other Communication Disorders. About half of all people 75 and older have hearing loss.

Don't ignore hearing loss later in life

Although common, don’t accept hearing loss as “part of getting older.” Just like vision, hearing is a critical brain activity. Untreated hearing loss—even mild hearing loss—can lead to auditory deprivation

Simply put, hearing health = brain health.

Why does it happen?

As we get older, degeneration within the inner ear and along the nerve pathways to the brain can impact our hearing. Most of the time, these changes are related to the health of tiny hair cells in the inner ear that help us hear. These hair cells translate the sound waves our ears collect and translate them into electrical signals for the brain to interpret as recognizable sound.

Since hair cells do not regenerate or regrow, any hearing loss we experience as a result of this damage is permanent.

How does it affect my hearing?

For the most part, age-related hearing loss (ARHL) occurs gradually over the span of many years. It usually affects both ears simultaneously (known as “bilateral hearing loss”) and causes high-frequency hearing loss, meaning higher-pitched sounds are harder to hear.

When listening to people speak, this means certain consonants are harder to hear, making words like “that” and “sat” sound the same.

Types of presbycusis

Presbycusis is one of the most common types of sensorineural hearing loss, which means hearing loss is related to deterioration of the cells within the inner ear and/or nerve pathways to the brain.

There are also a few other less common types of presbycusis that differ slightly in how and when they affect people, and a person may have multiple forms. According to Canadian Hearing Services:

  • Metabolic presbycusis is a reduction of blood supply in the inner ear.
  • Mechanical presbycusis is thickening of the tissues within the inner ear.
  • Mixed presbycusis is a combination of any of these.
  • Indeterminate presbycusis is the term when a cause can be determined — and it’s actually the most common.

Will I lose my hearing as I get older?

It depends largely on your genetic and medical history, as well as your exposure to noise over the years. A firearm enthusiast is at much higher risk than a gardener, for example. Because of the nature of their work, veterans are at perhaps highest risk for both hearing loss (and tinnitus) as they get older. In general, factors that contribute to presbycusis include:

  • Noise-induced hearing loss (NIHL). Prolonged exposure to excessive noise at work, home or during leisure activities can cause this type of hearing loss. This is by far the biggest risk factor!
  • Did your parents have hearing loss? You may have inherited that tendency, too.
  • Certain medical conditions that affect the blood supply to the middle ear, such as heart disease, high blood pressure, diabetes and other circulatory problems. Some women may experience hearing loss after menopause, or notice an increase in tinnitus.
  • Ototoxic medications, which are drugs that can affect hearing. For example, toxic side effects of certain medications, such as aspirin and antibiotics, can negatively affect your hearing. Compared to younger adults, older adults are more likely to take medication and experience side effects.

How is age-related hearing loss diagnosed?

If any of the symptoms we’ve listed are affecting your ability to hear, make an appointment to see a hearing healthcare professional as soon as possible for a hearing evaluation. The results of this evaluation will help determine the cause and extent of your hearing loss, as well as the best solution for treating the problem.

Is there a cure for presbycusis?
You are never too old for hearing aids

Like most types of sensorineural hearing loss, there is no cure. Fortunately, though, most cases of sensorineural hearing loss can be treated. Keep in mind that people in their 80s, 90s and beyond can wear hearing aids—there is no age limit.

  • Hearing aids. Those with mild-to-moderate hearing loss may benefit from wearing hearing aids. After a thorough hearing evaluation, a hearing healthcare professional will recommend the type and style of hearing aid according to the severity of your hearing loss, lifestyle preferences and budget.
  • Cochlear implants, which can be given to older adults. If you are diagnosed with severe or profound hearing loss, you may benefit from using a cochlear implant. These medical devices are surgically implanted behind your ear to help detect sound and understand speech. 
  • Assistive listening devices (ALDs). Technology is available to amplify sound from your television, telephone and other personal electronic devices. ALDs can be used with or without hearing aids, depending on the type and severity of your hearing loss.

Can I prevent hearing loss associated with old age?

While you can’t do anything about your relatives (much as many of us try), you can take steps to prevent hearing loss

  • Be aware of loud noises in your environment. According to the NIDCD, noise-induced hearing loss is the only type of hearing loss that is completely preventable. Sounds measuring more than 85 decibels (think heavy city traffic, motorcycles, emergency sirens and rock concerts) for long or repeated periods of time can permanently damage your hearing. Hearing health experts recommend wearing earplugs or other hearing protection when you’re working or playing around noisy equipment or recreational vehicles. If you can’t reduce the noise or protect your ears, move away from it.
  • If you’re diabetic, have heart disease or other circulatory problems, follow your doctor’s guidelines for diet and exercise. The hair cells in the inner ear depend on good blood flow to keep them healthy. Maintaining a healthy weight and exercising regularly can facilitate hearing health.
  • Ask your doctor about the medications you’re taking. Are they linked to hearing loss? If so, ask if she can prescribe an alternative medication. If you take large amounts of aspirin or other pain relievers, cut back or try to find alternative methods of pain relief.

Health risks of untreated hearing loss when you're older

Research indicates untreated hearing loss among older adults puts people at a greater risk for developing dementia and Alzheimer’s disease as well other emotional and physical problems. The good news? Hearing aids can delay dementia and provide other health benefits.

They’ll also help you live better. Although today’s hearing aid technology won’t restore your hearing to normal, it will greatly improve your quality of life. This quality-of-life boost applies to any older adult with hearing loss, including those in nursing homes and assisted living.
