OverviewHearing loss that occurs gradually as you age (presbycusis) is common. Almost half the people in the United States older than age 65 have some degree of hearing loss. Show
Hearing loss is defined as one of three types:
Aging and chronic exposure to loud noises both contribute to hearing loss. Other factors, such as excessive earwax, can temporarily reduce how well your ears conduct sounds. You can't reverse most types of hearing loss. However, you and your doctor or a hearing specialist can take steps to improve what you hear. SymptomsSigns and symptoms of hearing loss may include:
When to see a doctorIf you have a sudden loss of hearing, particularly in one ear, seek immediate medical attention. Talk to your doctor if difficulty hearing is interfering with your daily life.

How you hearYour ear consists of three major areas: outer ear, middle ear and inner ear. Sound waves pass through the outer ear and cause vibrations at the eardrum. The eardrum and three small bones of the middle ear amplify the vibrations as they travel to the inner ear. There, the vibrations pass through fluid in a snail-shaped structure in the inner ear (cochlea). Attached to nerve cells in the cochlea are thousands of tiny hairs that help translate sound vibrations into electrical signals that are transmitted to your brain. Your brain turns these signals into sound. How hearing loss can occurCauses of hearing loss include:
Mayo Clinic Minute: What is hearing loss?Vivien Williams: Hearing loss is very common. Matthew Carlson, M.D.: There's a lot of different types of hearing loss. Vivien Williams: Dr. Matthew Carlson says temporary hearing loss can happen when your ears are plugged with wax or fluid behind the ear drum, for example. Nerve-related hearing loss is usually permanent. Dr. Carlson: We call it sensorineural hearing loss. There are thousands of different causes of sensorineural hearing loss. The most common is probably just being over the age of 50… Vivien Williams: …or having a history of loud noise exposure. Dr. Carlson says just about all types of sensorineural hearing loss have to do with the loss of the function of hair cells in your inner ear. Dr. Carlson: The hair cells, which are the end part of the inner ear that actually take the mechanical sound and turn it to electrical sound… Vivien Williams: …become fewer or don't function well. Hearing aids help to increase volume. For people with profound hearing loss, cochlear implants work by bypassing the hair cells and sending signals directly to the hearing nerve and brain. Once health care professionals figure out your type of hearing loss, they can tailor treatment that's best for you. For the Mayo Clinic News Network, I'm Vivien Williams.

Risk factorsFactors that may damage or lead to loss of the hairs and nerve cells in your inner ear include:
Comparing loudness of common soundsThe chart below lists common sounds and their decibel levels. The Environmental Protection Agency's (EPA) safe noise level is 70 decibels. The louder the noise, the less time it takes to cause permanent hearing damage.
Maximum sound-exposure durationsBelow are the maximum noise levels on the job to which you may be exposed without hearing protection, and for how long.
ComplicationsHearing loss can have a significant effect on your quality of life. Older adults with hearing loss may report feelings of depression. Because hearing loss can make conversation difficult, some people experience feelings of isolation. Hearing loss is also associated with cognitive impairment and decline. The mechanism of interaction between hearing loss, cognitive impairment, depression and isolation is being actively studied. Initial research suggests that treating hearing loss can have a positive effect on cognitive performance, especially memory. PreventionThe following steps can help you prevent noise-induced hearing loss and avoid worsening of age-related hearing loss:
Mayo Clinic Minute: Can You Slow Down Age-Related Hearing Loss?Are you increasing the volume on the TV or asking others to speak up? You're not alone, especially if you're over age 50. "Age-related hearing loss is called 'presbycusis.'" The older you get, the more wear and tear you have on your ears says Dr. Gayla Poling. "That's when we start noticing age-related hearing loss." Dr. Poling says the majority of hearing loss is preventable. Hunters, for instance, are at risk of hearing loss. "If you can wear hearing protection, especially designed hearing protection typically for hunting, where you can reduce the loud noise exposure but still hear the environment around you, that can really prevent long-term damage." Dr. Poling says a hearing test can help evaluate whether you've experienced hearing loss. "We're looking at the threshold that which you can hear sounds the softest, and you're usually pressing a button or raising your hands or somehow responding to when you hear those sounds. And we're evaluating the entire auditory system in that process - not just with the earphones, but we do some other tests to evaluate your middle ear and the inner ear, as well." So before you have to turn up the sound, consider turning it down. For the Mayo Clinic News Network, I'm Ian Roth. Which outcome is a typical hearing difficulty experience by older adults?Hearing and Cognitive Health
Studies have shown that older adults with hearing loss have a greater risk of developing dementia than older adults with normal hearing. Cognitive abilities (including memory and concentration) decline faster in older adults with hearing loss than in older adults with normal hearing.
Which of the following is true about hearing loss in late adulthood?Which of the following is true about hearing loss in late adulthood? -It affects safety and enjoyment of life.
Which of the following is statistically true of older drivers quizlet?Which of the following is statistically true of older drivers? They have more accidents per miles driven than younger drivers.
What is the most serious consequence stemming from the loss of balance among older adults?Loss of balance also raises the risk of falls. This is a serious and even life-threatening complication. Falls are the leading cause of injuries—including fatal injuries—for people older than 65, and especially those over age 80.
