How Are Smoking and Hearing Loss Related?

Smoking can damage your hearing. If you’re one of the 40 million U.S. adults who smokes cigarettes find out why it may be time to get a hearing test.

The connection between smoking and heart disease, cancer, and respiratory problems gets all the attention, but the effects of smoking on hearing have long been known. If you’re one of the 40 million U.S. adults who smokes cigarettes — or someone who lives with a smoker — read on to find out how smoking is linked to hearing loss.

Some Facts

How does smoking affect hearing?

  • Compared to nonsmokers, smokers have a 70% greater chance of developing hearing loss.
  • Nonsmokers are twice as likely to develop hearing loss if they live with a smoker.
  • The greater your daily average of cigarettes, the greater your risk of developing hearing loss.
  • Mothers who smoke during pregnancy increase their child’s risk for developing speech-language problems.
  • If you work around high levels of occupational noise, smoking increases your risk of noise-induced hearing loss.
  • Adolescents exposed to secondhand smoke are 2 to 3 times more likely to develop hearing loss — and they usually aren’t even aware of it.

Some Culprits

Different studies have reported different suggestions for how smoking damages hearing. Here are some common culprits.

Eustachian tube

Your eustachian tube runs from your middle ear to the back of your throat. It equalizes the pressure in your ears, and it drains the mucous created by the lining of your middle ear. Smoking leads to problems — and even blockages — in the eustachian tube, causing pressure buildup and hearing loss.

Blood Pressure

Smoking impacts your blood pressure. What does that have to do with your hearing? The structures in your inner ear depend on good, sturdy blood flow. When your blood pressure changes, your inner ear has difficulty processing sound. In pregnant women, smoking restricts blood flow — and, therefore, the oxygen supply — to the fetus. The developing inner ear doesn’t get enough oxygen, so it develops more slowly and could lead to speech-language problems later.

Neurotransmitters

Neurotransmitters are messengers that carry information between the cells in your body. Nicotine interferes with how your body regulates a key neurotransmitter — one that is crucial for transporting sound information from your inner ear to your brain. This means your brain isn’t getting enough sound input, so it has a harder time making sense of the sounds you hear.

Central nervous system

The parts of your central nervous system that create your ability to hear are still developing in late adolescence. This system is easily damaged by toxins — such as nicotine — during its development, which could explain the prevalence among adolescents of hearing loss due to secondhand smoke.


Though hearing loss caused by smoking can’t be reversed, it’s never too late to quit smoking to avoid further damage to your hearing. Contact us to schedule an appointment to get your hearing tested!

Hearing loss and Cochlear Implants

Many patients ask if they have enough hearing loss to qualify for a cochlear implant. That can only be determined by a thorough diagnostic hearing evaluation. If a patient’s hearing loss reaches a severe level (which some insurances have certain required levels of severity of hearing loss), then the patient would need to meet with a surgeon to determine if they are a surgical candidate for implantation. If a patient is implanted, we do follow up implant mapping (programming) at our location.

Is Tinnitus Affecting Your Brain’s Emotional Processes?

Anyone afflicted with the annoying ringing and hissing of tinnitus is well aware of the stress, anxiety, and irritability that accompany these phantom noises — but could tinnitus alter an individual’s emotional processing altogether? Research on the subject from the University of Illinois suggests this may be the case.

Using MRI scans to show which areas of the brain respond to various auditory stimuli, researchers found that when compared with normal-hearing people, those with tinnitus showed less activity in the amygdala — a region of the brain associated with emotional processing — but more activity in two other regions associated with emotion.

The findings suggested to researchers that the amygdala in those who suffer from tinnitus had become less active because the brain had adjusted to the tinnitus. In other words, the amygdala couldn’t be active all the time due to the annoying sound, and perhaps other areas of the brain became more active to make up for that reduced activity. This may have translated to an altered emotional state because of the difference in how the brain was processing emotions.

For many, tinnitus relief can be found through a treatment called masking. The technique involves using white noise (either natural or artificial) to cover the sounds of the tinnitus, allowing you to focus more on the sounds of the world around you.

Better Hearing Q&A: Is There A Link Between Hearing Loss And Dementia?

Phrenology1Our patients always have great questions about hearing and hearing technology. We feel it’s our obligation as the community’s only AudigyCertifiedTM hearing professionals to provide you more than exceptional hearing care and technology recommendations; we are here to give you the informative answers you’re looking for so you can confidently make educated decisions about your hearing health.

Q: I’ve heard that there’s a link between hearing loss and dementia—is this true?

A: What an important question. This subject has been in the news quite a bit lately. For years researchers have suspected a connection between hearing loss and dementia, but just this year a study funded by the National Institutes of Health determined that a mild hearing loss of 25 decibels (dB) can increase the development of cognitive problems by 30% to 40%.

When asked for an explanation of the cognitive decline, Frank Lin—Johns Hopkins University School of Medicine otologist and assistant professor, and the study’s lead author—offered as possible contributing factors the combination of social isolation and the extra mental effort it takes to understand sounds.

Dementia is on the rise in the U.S. with over 4 million affected by the malady, and recent estimates place the cost on families and society at $157 billion to $215 billion a year, making it more expensive than cancer and heart disease.

Hearing should become a regular part of the conversation during general health exams, and regular hearing evaluations the norm, in order to delay the onset of cognitive decline.

While hearing aids aren’t a cure for the effects of dementia, appropriately fit hearing technology is designed to alleviate the energy required to understand sounds, and to decrease feelings of isolation by reengaging people with the world around them through better hearing.

Diabetes and Hearing Loss

Original post from The Hearing Care Blog

human-ear-listening-hearing-263654721Diabetics at Greater Risk for Hearing Loss

People with diabetes are usually aware of their increased risk of kidney, cardiovascular, and visual disorders. However, most diabetics don’t know they are more than twice as likely to have hearing loss as those without the disease. And the risk is greater among younger diabetics than older.

Younger Diabetics at Greater Risk

A recent study in Japan was published in November 2012 in The Journal of Clinical Endocrinology & Metabolism. Led by Chika Horikawa, the team examined data from 13 previous studies published between 1977 and 2011. Their conclusion? Not only were diabetics 2.15 times as likely as others to have hearing loss, but those under age 60 had 2.61 times the risk while those over 60 had 1.58. In a related study by the National Institutes of Health, it was shown that more than 40% of people with diabetes had some degree of hearing loss.

Link Between Diabetes and Hearing Loss

The link between diabetes and hearing loss is not yet fully understood. Some think that high blood sugar levels may damage the blood vessels in the ears. Others caution that certain medications commonly used by diabetic patients, such as diuretics, may be a contributing factor. Though more research is needed in order to understand the connection between diabetes and hearing loss, according to Horikawa, “these results propose that diabetic patients are screened for hearing impairment from an earlier age compared with nondiabetics,” particularly because untreated hearing loss is associated with an increased risk of dementia and depression.

Researchers Identify Genetic Mutation Responsible for Age-Related Hearing Loss

From HealthyHearing.com

In a nine-year study that was a collaboration between University of South Florida’s Global Center for Hearing & Speech Research and the National Technical Institute for the Deaf at the Rochester Institute of Technology, researchers were able to identify the first genetic biomarker for presbycusis. The genetic mutation carried by those who ultimately suffer from age-related hearing loss is linked to speech processing abilities in older people.

In collaboration with the House Ear Institute in Los Angeles, the researchers discovered a gene that produces a key protein in the inner ear — the cochlea — called glutamate receptor metabotropic 7 (GRM7). The GRM7 protein is intimately involved in converting sound into the code of the nervous system, in the cochlea, which is then sent to the parts of the brain used for hearing and speech processing.

Now having identified the gene, the researchers said people can be tested and takes steps earlier in life — such as avoiding loud noises, wearing ear protection and avoiding certain medicines known to damage hearing — to protect their hearing.

“This gene is the first genetic biomarker for human age related hearing loss, meaning if you had certain configurations of this gene you would know that you are probably going to lose your hearing faster than someone who might have another configuration,” said Robert Frisina Jr.

The Frisinas launched their study of genetics’ role in hearing loss nine years ago in hopes of identifying the cause of one of the most common forms of permanent hearing loss. Clinically, age-related hearing loss has been defined as a progressive loss of sensitivity to sound, starting at the high frequencies, inability to understand speech, the lengthening of the minimum discernible temporal gap in sounds, and a decrease in the ability to filter out background noise. Researchers now know the causes of presbycusis are likely a combination of multiple environmental and genetic factors.

Age-related hearing loss is a very prevalent problem in our society. It costs billions of dollars every year to manage and deal with it. It’s right up there with heart disease and arthritis as far as being one of the top three chronic medical conditions of the aged,” said Robert Frisina Jr.

DNA analyses were conducted and completed at the University of Rochester Medical School and the Rochester Institute of Technology.

The study involved 687 people who underwent three hours of extensive examination of their hearing capabilities, including genetic analyses and testing of speech processing.

National Alzheimer’s Disease Awareness Month – Alzheimer’s and Hearing Loss

From the Better Hearing Institute

If you or someone you love has been diagnosed with Alzheimer’s disease or is showing signs of dementia, a thorough hearing check is in order.

Studies suggest that hearing impairment contributes to the progression of cognitive dysfunction in older adults. If not managed, as for example with hearing aids, hearing loss can interrupt the cognitive processing of spoken language and sound.

When an individual has both Alzheimer’s and hearing loss, many of the symptoms of hearing loss can interact with those common to Alzheimer’s, making the disease more difficult than it might be if the loved one has been treated for hearing loss.

When left unaddressed, hearing loss can compound the difficulties that people with Alzheimer’s and their families already face. But in many cases, the appropriate use of hearing aids can benefit people with hearing loss, including those with Alzheimer’s and their caregivers.

Numerous studies have linked untreated hearing loss to a wide range of physical and emotional conditions, including impaired memory and ability to learn new tasks, reduced alertness, increased risk to personal safety, irritability, negativism, anger, fatigue, tension, stress, depression, and diminished psychological and overall health.

A comprehensive hearing assessment should be part of any medical evaluation prior to the evaluation of dementia. By addressing the hearing loss, quality-of-life for those who have Alzheimer’s can be improved and they can live life as fully as possible.

Alzheimer’s disease is a type of dementia that causes problems with memory, thinking and behavior. Today, an estimated 5 million Americans are living with Alzheimer’s, and they are supported by nearly 15 million caregivers. Alzheimer’s disease is the sixth-leading cause of death in the United States. (Source: Alzheimer’s Association)

4 Reasons to Make a Hearing Test Part of Your Yearly Check-up Routine

There are many reasons why having a regular hearing test is a good idea, even if you have normal hearing.  Hearing is our most important social sense; it is what allows us to communicate with one another and connect with our friends, families, and loved ones.  A yearly test is particularly important if you have other disorders which have been identified as possible causes of hearing loss, such as diabetes, high blood pressure, heart disease, and a history of certain infections, particularly in childhood.

As more research is conducted into the impact of hearing loss, we learn about exactly how insidious the disorder can be.

Hearing loss has also been identified as a risk factor for other disorders, particularly disorders that affect cognitive health.  Four of these disorders are particularly important as a person continues to age:

  1. Dementia – Researchers at Johns Hopkins University recently found that individuals who have untreated hearing loss are significantly more likely to develop dementia time than those people who seek early treatment for their hearing loss.  This relationship could be due to a number of factors, such as social isolation, increased cognitive strain or a similar underlying pathology.
  2. Brain Atrophy – This study was released by the Perelman School of Medicine at the University of Pennsylvania. Researchers found that brain volume decreased among patients with untreated hearing loss, a condition that made it more difficult for those particular subjects to understand complex sentences.
  3. Depression – In 1999, a National Counsel on Aging survey of 2,300 hearing impaired adults age 50 and older found that those with untreated hearing loss were more likely to report depression, anxiety, and paranoia and were less likely to participate in organized social activities, compared to those who wear hearing aids.
  4. Risk of Falling – Though some people have issues with their hearing that involve their vestibular (balance) function, this study looks more at the direct nature between even a so-called mild hearing loss and fall risk.   All other risk factors aside, a person with hearing loss is three times more likely to fall, and that risk increases dramatically as the hearing loss progresses.

These are just a few of the ways in which even a so-called mild hearing loss can affect a person’s lifestyle on a larger scale.  A yearly hearing test, particularly for those patients with risk factors for hearing loss, can help insure that treatment is sought for the hearing loss when it is needed.  Also, yearly tests can serve as valuable tools to monitor the progression of hearing loss over time, allowing any hearing aid prescribed to be appropriately fit to an individual’s hearing needs.

To schedule your yearly or baseline hearing test, call us today for an appointment.  Our Four-Step Process is centered around discovering your individual hearing and listening needs, even if you just need a baseline examination.  We have appointment times available Monday thru Friday, so we’re sure to have one that’s perfect for your busy schedule.  Let us help you keep on top of your hearing health needs!

Hearing Loss Affects About 1 in 5 Americans, Research Says

Nov. 14, 2011. About one in five Americans ages 12 and older suffer from hearing loss that’s severe enough to make communication difficult, researchers from Johns Hopkins University found.

About 30 million Americans, or 13 percent of the population, have hearing loss in both ears, and 48 million, or 20 percent, in at least one ear, according to a study published today in the Archives of Internal Medicine. That exceeds previous estimates, which put the number of people with hearing loss at 21 million to 29 million, the researchers said.

The study also found that hearing loss doubled every decade of life. Deficient hearing has been linked to a greater risk of dementia, poor cognitive function and falling in the elderly, said lead study author Frank Lin, an assistant professor of otolaryngology and epidemiology at Johns Hopkins in Baltimore. The impact of hearing loss on the aging isn’t “inconsequential” and should be treated, he said.

“If you have poor hearing, your brain almost has to work harder to decode and process sound,” said Lin in a Nov. 11 telephone interview. “If you brain is having to reallocate resources to hearing, it probably comes at the expense of cognition or thinking ability.”

Researchers in the study used data from the National Health and Nutritional Examination Surveys from 2001 to 2008 for all participants ages 12 and older who had their hearing tested over that period. The survey is thought to be representative of the U.S. population.

Worse With Age
For those in their 40s, about 2.8 million suffer from hearing loss in both ears and 5.6 million have the condition in at least one ear. That number jumped to 8.8 million for people in their 70s who had hearing loss in both ears and 10.8 million for those who had hearing loss in at least one ear, the study showed.

Women and black people were less likely than other groups to suffer from hearing loss, the study found. Lin said estrogen may be protective of hearing and the same cells that make skin dark may also play a role in preventing hearing loss.

Today’s study “gives us the real scope of the problem for the first time and shows us how big of a problem hearing loss really is,” Lin said in a statement.

New Research Links Hearing Aid Use to Improved Self-Esteem

Better hearing can make a big difference in your overall mental fitness.

Last year was a big year for hearing studies, particularly as hearing health relates to mental health.  We saw multiple studies that linked untreated mild hearing loss to disorders such as dementia and brain atrophy.  A new study was just released that offered a bit of positive news: hearing aid use may actually increase self-esteem.

The study, conducted by Hear the World, showed that a majority of hearing aid users experience better overall mental fitness than people who allow their hearing loss to go untreated.  Quality of life, intimacy, personal confidence, even insomnia tend to improve for people who wear hearing aids.  And when you think about it, this makes a lot of sense.  Our hearing is our most important social sense; it’s the principle component of how we communicate with one another.  To quote Helen Keller, hearing loss “means the loss of the most vital stimulus — the sound of the voice that brings language, sets thoughts astir and keeps us in the intellectual company of man.”

One of the most important things that we do at Advanced Hearing is work with our patients to restore their quality of life where their hearing loss interferes.  It isn’t a surprise for us to see the results of this study.  We see the importance of better hearing everyday in our patients.  It’s our biggest passion and our greatest privilege.  To experience the difference better hearing can make, call us today.
