HOW MINERALS CAN PROTECT YOUR HEARING

You’ve heard it before: be sure to get all your vitamins and minerals! Some people swear by a multi-vitamin supplement and some like to get all the needed nutrients from food. Either way, most people understand that getting enough vitamins and minerals is important for optimal health. It’s common knowledge that Vitamin C and zinc can boost immunity and calcium can benefit bones and teeth. But did you know that there are minerals that are important to maintain healthy hearing as well?

Why do we need minerals?

Minerals are inorganic elements that are found in rock and soil; they are essential, meaning the body needs them and does not manufacture them on its own. We get minerals by eating vegetables that absorb them from the soil in which they are grown, as well as from the meat of animals that have grazed on vegetation.

A few important minerals for hearing health are potassium, folate, magnesium and zinc.

Potassium helps to regulate the fluids in our blood and tissues. Our inner ears contain fluid that is crucial to helping our bodies translate noise into understandable sounds. Thus our brains are dependent on this fluid, and a rich supply of potassium, to hear and understand the world around us.

Fortunately, potassium is easily found in common foods such as tomatoes, bananas, yogurt, spinach, potatoes, raisins, lima beans, melons, milk and oranges. Getting a healthy variety of fresh, whole foods in your diet and “eating the rainbow” can assure you get plenty of potassium.

Folate is an important nutrient for new cell growth in the body. Folic acid, the synthetic form of folate, is also available in supplement form, though it is best to try to get folate from food such as spinach, broccoli, asparagus, and organ meats.

Magnesium is another important mineral that has been shown in studies to protect against hearing loss. Magnesium can help to combat free radicals that are produced when exposed to very loud noises, protecting the hair cells of the inner ear. Magnesium also contributes to healthy blood vessels, which deliver valuable oxygen to the ear, crucial to hearing health.

Magnesium can be found in a variety of delicious foods, including artichokes, bananas, potatoes, spinach, tomatoes and broccoli.

Zinc is an immune-booster for the body, as you may know from some supplements on the market that contain zinc and claim to ward off cold and flu viruses. Zinc also assists with cell growth and wound healing. Some studies have found zinc effective in treating tinnitus and ear infections as well, though it can sometimes interact with pharmaceutical antibiotics and diuretics.

Zinc is found in foods such as pork, dark-meat chicken and pork, cashews, almonds, lentils, split peas, beans, peanuts, oysters and dark chocolate. Good news for nutty dark chocolate lovers!

The great news is that as long as you’re getting a balanced diet of fresh, whole foods, you are probably getting a good balance of these minerals and other nutrients that contribute to hearing health.

WHAT IS HIGH FREQUENCY HEARING LOSS AND WHAT CAN I DO ABOUT IT?

Have you ever had a misunderstanding when communicating with someone else? Everyone has; misunderstandings in communication are a common occurrence. You may misunderstand what someone else is saying for a variety of reasons, from background noise to just not paying attention.

People with high-frequency hearing loss, however, have greater difficulty hearing or understanding anything within the 2,000 to 8,000 Hertz range. Female voices often fall in this range, so sometimes it becomes more difficult for people with high-frequency hearing loss to understand female communication. They may also have trouble hearing high-pitched noises like beeping machinery or birds singing.

High-frequency hearing loss is the result of damage of the sensory hearing cells in the inner ear or cochlea. Tiny hair cells in the cochlea serve to render sound from the outside world into electrical impulses that our brains can then recognize as understandable sounds. When a person suffers from hearing loss, they typically have trouble with higher frequencies before lower frequencies.

What Causes High-Frequency Hearing Loss?

Many things can cause high-frequency hearing loss, and people of all ages can be affected. When children suffer from high-frequency hearing loss, it can disturb learning by hindering communication and speech development, and hamper learning in school.

  • Noise-Induced Hearing Loss (NIHL) is when a person is exposed to dangerous levels of noise every day. It can also be the result of exposure to a very loud noise, such as a gunshot or explosion, one time. Noise levels over 85 decibels on an ongoing basis can also result in NIHL. It is estimated that more than 10 million Americans have suffered irreversible hearing damage due to NIHL.
  • As we age, hearing loss called presbycusis can occur. This damage occurs slowly and affects both ears equally, so it can be hard to notice until it has progressed to a serious level. Signs of presbycusis begin with an inability to understand communication in loud environments.
  • Certain diseases, such as Meniere’s disease can affect the inner ear and may result in fluctuating hearing loss or vertigo. Chronic ear infections in children, if left untreated, can also result in permanent hearing damage.
  • High frequency hearing loss can also be passed down through genes, so if you have family members who have suffered, it is possible you are genetically predisposed to this problem.
  • Some over-the-counter drugs, such as aspirin and ibuprofen, are ototoxic, which means they can damage hearing. Drugs used in chemotherapies and aminoglycoside antibiotics can also be harmful.

Is high-frequency hearing loss curable?

High-frequency hearing loss is permanent, but it is often preventable. It is critical to protect your ears when there is exposure to dangerous levels of noise—especially if it is louder than 85 decibels. Live concerts, working around machinery, riding loud motorcycles or snowmobiles, or going to the shooting range can expose you to noise louder than 85 decibels.. Even listening to music too loud can eventually result in high frequency hearing loss! Noise-cancelling headphones as well as ear plugs can be helpful in mitigating this noise and damage to your hearing.

What are my treatment options?

Though high-frequency hearing loss is not reversible, it can be corrected in many cases with hearing aids. If you think you may have some level of hearing loss, schedule a hearing screening with an audiologist right away to prevent further damage.

HEARING DAMAGE AND CHILDREN’S DEVELOPMENT: EARLY DETECTION IS KEY

As children grow, hearing ability is vital to developing speech and language skills. Traditionally it has been difficult to discern a hearing difficulty with children under two years of age, until it became apparent that speech abilities were delayed.

It has been shown, however, that if early detection of a hearing issue can be diagnosed prior to six months of age, speech impairment and delays can be drastically reduced. For this reason, infant hearing screening is now common in US hospitals and children with hearing loss can be identified and treated in infancy.

Research studies have indicated that between 5 children in 1,000 may suffer from hearing loss, most diagnosed between the ages of three and 17 years old, and there may be as many as 1.4 in 1,000 newborns with hearing impairment at birth.

How Can Children Have Hearing Loss?

Childhood hearing loss has become much more prevalent in recent years due to environmental noise. A 2013 CDC study estimated that at least 12.5% of children and teens ages six to 19 have permanent hearing damage because of noise exposure.

Parents, guardians, teachers and doctors need to be aware of the signs of hearing loss in children, because early diagnosis and treatment is key to arresting hearing loss and preventing lifelong damage to hearing. Undiagnosed hearing loss in young children can cause developmental delays and substantial emotional issues for children that can be difficult to overcome even into adulthood.  

Congenital Hearing Impairment

Some hearing damage is already present at birth: this is called congenital hearing loss. There are many causes of congenital hearing loss, with both genetic and non-genetic factors.

Non-genetic factors may include:

  • Premature birth with a birth weight of less than 3 pounds or the necessity of respiratory drugs.
  • Maternal diabetes.
  • Maternal alcohol or drug abuse.
  • Birth complications, including the presence of diseases such as rubella, herpes or another infection.
  • Lack of oxygen at birth or need for a blood transfusion at birth.
  • A brain disorder or nervous system issue.
  • Use of ototoxic medication by the mother during pregnancy—such as antibiotics or over-the-counter medications like NSAIDS (ibuprofen or acetaminophen).

Non-genetic factors account for about 25% of congenital hearing loss, and genetic factors caused by heredity cause over 50% of hearing loss in children. Sometimes this hearing loss is evident at birth, and sometimes it is revealed later in life.

Genetic Hearing Loss Factors May Include:

  • Autosomal Dominant Hearing Loss, which accounts for approximately 15% of genetic hearing damage, is acquired because one parent carries a dominant gene for hearing loss and passes it to the child. The parent may or may not manifest hearing loss.
  • Genetic syndromes such as Waardenburg Syndrome, Down Syndrome, Usher Syndrome, Teacher Collins Syndrome Crouzon Syndrome or Alport Syndrome may cause hearing damage at birth.
  • Autosomal Recessive Hearing Loss is the most common genetic congenital hearing damage cause, accounting for about 70% of genetic hearing impairment. In this case, neither parent has hearing loss, but both parents carry a recessive gene for hearing loss that are passed to the child. Most parents are not aware they carry this recessive gene and are thus astonished when the child displays hearing damage for this reason.

In some cases, the reasons for infant hearing loss are unknown, making up the balance of the hearing loss cases at birth.

Acquired Hearing Impairment

Many children are not born with hearing damage but attain it during childhood. Reasons for acquired hearing loss can be:

  • Taking ototoxic medications
  • Serious head injury
  • A perforated eardrum
  • Infections such as measles, mumps, whooping cough or meningitis
  • Exposure to second-hand smoke
  • Untreated or frequent ear infections
  • Exposure to loud noises (which cause noise-induced hearing loss)
  • Otosclerosis or Meniere’s diseases (progressive)

Temporary Hearing Damage

Fluctuating or transient hearing impairment in childhood can also impair language development and speech. Temporary hearing loss can be caused by ear infections, and at least 75% of children have had this type of ear infection by the time they reach 3 years of age.

Transient hearing loss caused by an ear infection happens when fluid blocks the vibrations of the middle ear bones and muffle sound. Because it is usually temporary, this type of hearing loss often resolves itself with the healing of the ear infection, though if ear infections are frequent or untreated, permanent damage can occur.

If you are concerned a child in your life may have hearing damage, it is crucial to make an appointment for a hearing screening to determine the best course of action. Hearing damage is treatable, especially if caught early, but is not reversible.

EAR BUDS MAY LEAD TO HEARING LOSS But it Can Be Avoided!

Ear buds and headphones are a great way to have your own personalized entertainment experience wherever you go. Whether you like to listen to music or watch your favorite video content on your phone, ear buds are necessary to listen to audio in a public setting.

Since ear buds are speakers inside of your ear canal, however, they can cause hearing damage, even without us realizing it. Irreversible hearing loss can result from loud noises, and if the volume goes too high for too long, you could be at risk for hearing damage. Studies have shown that as many as 1 in 5 young people may already suffer from hearing damage, because of the ubiquitous and constant use of ear buds.

Noise-induced hearing loss can occur in one of two ways: from a sudden, loud noise such as an explosion, or from ongoing exposure, such as working in a factory setting or constantly listening to loud music.

When ear buds rest in your ear canal, the sound effect can be boosted by up to 9 decibels. Since 85 decibels is the threshold for hearing damage, this extra 9 decibels may just push the sound over that limit and begin to damage your hearing.

None of this is to say that you should never wear ear buds or head phones. Here are a few suggestions to minimize damage and prevent noise-induced hearing loss from your ear buds:

  • Custom ear buds can be made that fit your ear canal perfectly. This serves to effectively block out outside noise, so you don’t feel the need to increase the volume in noisy environments.
  • Earbuds that fit tightly into your ear canal can serve the same purpose as custom earbuds by sealing into your ear and blocking background noise.
  • Use the 60/60 rule: always keep the volume under 60% and try not to use them for more than 60 minutes per day.
  • Wear “ear-muff” style headphones instead of ear buds.
  • Alert young people in your life of this information; since hearing damage is irreversible, education is important.

With just a little bit of effort, you can preserve your hearing and still enjoy personal entertainment wherever you go.

Since hearing loss can progress slowly, annual hearing screenings are crucial. We may not notice these gradual changes in hearing ability on our own until damage is done.

EXERCISE MAY BE GOOD FOR YOUR EARS, TOO!

How much exercise do you get in a typical week? Whether it’s a run around the block, a long walk around the mall or a trip to the gym, we all know that movement is good for our bodies, but did you know it may be good for your hearing as well?

Studies now show that as many as 20% of Americans, and 33% of Americans over the age of 65, suffer from hearing loss. We have also learned that hearing loss can affect much more than just hearing: studies have shown increased risk of depression, dementia and social isolation when hearing loss is a factor. Hearing loss can also make it more difficult to work, which results in income loss for hearing loss sufferers. And since hearing loss is not reversible, anything we can do to prevent or slow hearing loss will be a positive.

The various structures of the ear breaking down as we age contribute to different types of hearing loss. It was found, however, that mice who exercised experienced an average of 5% hearing loss as they aged, while sedentary mice experienced 20% hearing loss.

Exercise increases circulation, which preserves necessary capillaries that deliver blood and oxygen to the ear to preserve the cochlea and other surrounding structures. Elevating your heart rate at least a few times a week is ideal, though taking a daily walk around the neighborhood is also beneficial.

The CDC (U.S. Center for Disease Control), 20% of Americans do not get adequate amounts of exercise. Exercise has so many proven health benefits that hearing loss prevention is just one more added onto a long list of positive things resulting from a less sedentary lifestyle.

Aerobic activity slows the aging process by increasing energy and oxygen to every cell of your body, contributes to faster recovery from chronic illness, improves your skin by increasing circulation, improves your mood by inducing a natural calm state, boosts brain health by reducing age-related loss of brain tissue, and gives you more energy throughout the day to do other activities and chores.

Exercising for only 16 minutes three times per week has been shown to improve health and contribute to all of these benefits. And of course, exercising also contributes to a healthy body weight and positive overall body image. In fact, many have found better results by short bursts of exercise rather than long, drawn out cardiovascular sessions. Staying in motion as much as possible during the day is an easy way to get the most benefit possible. Many people set 10,000 steps per day as a goal to motivate them to stay moving, utilizing tools such as fitness trackers and even health apps on smartphones.

Other ways to protect your hearing and prevent hearing loss are a healthy diet (avoid processed foods whenever possible and eat whole foods to maximize nutrient absorption), avoid loud noises and practice listening skills to train your brain to distinguish sound more effectively.

Because hearing loss can progress slowly, annual hearing screenings are crucial. We may not notice these gradual changes in hearing ability on our own until damage is done.

Smart Hearing Devices: Take Your Hearing Into the Future!

Our world is full of smart devices: from phones and cameras to TVs and even our electricity meters—our technology is smarter than ever! What does “smart” mean, exactly? It means our devices can communicate with each other, whether it be via apps on our phones or a Bluetooth or Wi-Fi connection. These smart devices make our lives easier by simplifying things we do every day.

Not to be left behind, hearing devices are now also smart! Not only can modern hearing devices communicate with other devices around us like our televisions and smart phones, they can even learn our preferences and adjust accordingly to deliver better sound quality and performance.

They Adjust To Your Environment

Hearing devices can gather auditory information from your environment and determine your listening needs from the situation. Because the environment in an outdoor park is very different from that of a baseball game, your listening needs will vary based on that environment. As you move from one place to the next, the hearing device can automatically adjust to optimize performance in that environment.

Make Manual Adjustments With Your Phone

Another advantage of smart hearing devices is the ability of a smart-phone to make adjustments that used to be manual. Taking out a hearing aid to adjust it is inconvenient and makes wearing them less discreet. With smart devices, these adjustments can now be made with the touch of a button on your smartphone.

They Learn Your Preferences

Smart hearing devices can also learn from the adjustments you make, and automatically adjust for you in future similar situations. So you will have to make less manual adjustments over time, and your hearing device will keep everything sounding seamless and clear.

They Connect To Each Other

Smart hearing devices are also wirelessly connected to each other, so an adjustment made to one affects both devices equally, and will require less hassle. This helps both ears to hear equally and accurately, and work together to help the brain process sounds.

They’re Interactive

Smart hearing aids can also help you to do things people without hearing aids can’t do: like stream music, a phone call or a television show straight to your ears and adjust the volume to your personal preference. Bluetooth and Wi-Fi technology effectively transform your hearing devices into HD stereo ear sets. You can even answer a call without touching your phone and adjust the volume on your TV without a remote!

Smart-phone apps for you hearing device help you to control your hearing aids discreetly, from adjusting the volume or treble to changing the direction of microphones. This makes adjusting your hearing device much easier than having to remove it and adjust it manually.

They Reduce Background Noise

These smart hearing devices are better than ever at blocking out disruptive background noise and helping your brain to pinpoint the sound you are trying to hear, whether you’re at a busy restaurant, a sporting event, or even blocking the sound of wind on a blustery day!

Smart hearing devices can help make your life easier every day, from work to play and back home. Come in and check out some of the latest hearing technology we have to offer, and you’ll see how these devices can make wearing hearing aids more convenient and effortless than ever!

How Can Hearing Loss Affect Your Energy?

You may know people who have boundless energy morning to night, even accomplishing many more tasks in a day than the average person. You yourself may feel that it is difficult to endure a night out with friends or a long meeting at work without feeling physically exhausted afterwards. If you have hearing loss, the reason for this is called “listening fatigue.”

Does Hearing Loss Make You Tired?

When suffering from hearing loss, it is much more difficult to listen and interpret language for long periods of time. People without hearing loss may never realize how much effort and energy just listening to others can expend. If you feel mentally and physically exhausted after interacting with others for long periods of time, you may be suffering from listening fatigue. And this fatigue doesn’t only affect you personally: it was estimated by the Better Hearing Institute that hearing loss and hearing fatigue may be responsible for more than $56 billion wasted annually due to lost productivity at work caused by hearing fatigue.

Many people who suffer from hearing fatigue become frustrated with their work situations and may even quit their jobs as a result. And even if they continue working, listening fatigue can affect them so they have little energy to pursue any fun or relaxing activities outside of work.

Why Hearing Loss is Tiring

When suffering from hearing loss, it becomes important to be on constant alert, straining to listen for sounds that would otherwise be effortless to hear, as well as engaging the mind in lip reading and other visual cues. It becomes mentally draining.

Three areas of the brain deal with interpersonal communication and listening throughout the day: the area for speech production, for speech comprehension, and to manage hearing. Without hearing loss, these areas of the brain work together for almost effortless hearing and comprehension, but with hearing loss it becomes more difficult and thus more tiring.

Hearing Aids to the Rescue

If you are suffering from hearing loss and hearing fatigue as a result, hearing aids can assist you by restoring the sounds that are missed by your ears, thus giving your brain a rest and making communication and understanding less difficult.

Tips to Reduce Listening Fatigue

If you find yourself exhausted from normal interactions during the day and suspect hearing fatigue, be sure to get a hearing test to see if hearing aids can bring you some relief. Other things you can do to minimize fatigue is to give yourself a break: go somewhere quiet for a few minutes to just relax and breathe. Go outside or just close your eyes and allow yourself to shut out the world for a few minutes. Also try to minimize interruptions and background noises during certain times of the day if possible. Take a quick nap or read a little bit to give your ears a break from their work during the day.

Could There be a Link Between Hearing Loss and Dementia?

As we age, most of us expect to experience some hearing loss. It is considered a normal part of aging, and other than hindered communication and minor annoyance, is not seen as a major health issue. More and more studies, however, are linking hearing loss with mental decline and dementia, which is increasing concern over this “minor” consequence of aging.

One study that involved more than 2000 people found that people with hearing loss had a decline in cognitive abilities 30-40% faster than those who didn’t. Another study involving 600 people showed that people with hearing loss were more likely to develop dementia than those without it. Further, people who had severe hearing loss were more likely to develop dementia than those with only mild or moderate hearing loss.  Testing and further studies have also found increased and quicker rates of brain atrophy in people with impaired hearing in comparison with people without impairment. In participants over 60 years of age, the risk of dementia was increased by 36% when hearing loss was a factor.

Hearing loss is not only a risk factor for dementia, but also seems to worsen the symptoms, including diminished memory, failure to learn new tasks, irritability, fatigue, anxiety, reduced awareness and depression, in addition to diminished overall health. In light of these findings, studies are currently underway to determine the effectiveness of hearing aids and other devices to halt or slow this mental decline.

Because hearing loss can progress slowly, annual hearing screenings are crucial. We may not notice these gradual changes in hearing ability on our own until damage is done.

Gene Therapy May be the Answer to Hearing Loss

One billion people throughout the world are at risk of experiencing hearing loss at some point in their lives. Scientists have therefore been working to find solutions to this growing problem. Hearing aids and cochlear implants have seen rapid improvements and advances in technology, but they still merely mimic the hearing process, and don’t cure it. Complaints such as tinny or robotic-sounding voices and diminished enjoyment of music are urging another way to restore hearing.

Progressive hearing loss is most often caused by the loss of hair cells in the inner ear that allow us to detect sound. Some bird and fish species are able to re-grow these cells, but humans cannot. It then follows that if humans could regrow these hair cells, hearing could be restored naturally.

Novartis, a Swedish pharmaceutical company, recently sponsored a set of clinical trials to test an inner-ear hair cell regrowth technique on human subjects. When conducting preliminary trials on mice, researchers were successful in restoring partial hearing. The trials are still ongoing, but the eight participants have already begun noticing improvement in their hearing abilities.

Atoh1 is the gene that triggers hair cell growth in the inner ear. Scientists have focused on this gene, which is “turned off” after the cells finish growing, even before birth. Scientists hope to use gene manipulation to “turn back on” these genes and promote this hair cell growth once again. They implant the gene into a cold virus and implant it into the eardrum using a laser and syringe.

Though participants have seen some improvement in hearing, total restoration has proven elusive. Scientists hope that this method may provide enough improvement that patients can then use hearing aids to further improve speech comprehension and other hearing abilities.

Scientists are also working to identify other genes that also play a role in this cell growth progression, and hope that eventually they may develop more advanced techniques for hearing restoration. Whereas this procedure is aimed at hearing loss caused by very loud sounds or drug toxicity, there is more research underway to find treatments for genetic hearing loss as well.

The approach is to introduce a DNA sequence that will help a “broken” gene to work again. Malfunctioning sensory cells are responsible for the hearing loss, and it is hoped that those cells can be made functional again.

This exciting new field of research may soon be able to reverse hearing damage and loss, but until then, prevention is key. Come in for a hearing test today and learn the best ways to protect your hearing health.

Welcome to May: Better Hearing Month!

With aging comes normal changes in hearing, as well as language and speech.

There are ways to maintain good hearing and speech, however. Here are a few ways to keep your hearing in tip-top shape:

Protection Can Prevent Hearing Loss. When participating in loud activities, such as going to a concert, mowing the lawn or spending time building in the shop, those loud noises can damage hearing. Exposing your ears unprotected to 105 decibels for one hour can damage hearing. Always use noise protection, such as earplugs.

How do you know if you are experiencing hearing loss? Do you keep your TV or radio at a level that others say is too loud? Do you often need to turn toward a sound to hear it better? Do you often ask others to repeat what they are saying? Do you have pain or ringing in your ears, or an ear infection?

If any of these is “Yes,” it is a very good idea to have a hearing test with an audiologist to prevent further damage. It is possible to treat hearing loss and stop it in its tracks, so don’t let it impact your daily life.

Speak normally. When in a loud environment, try not to strain your voice by yelling over the noise, because it can cause vocal damage or hearing impairment. Whispering and throat-clearing can also be hard on your vocal cords. If your throat feels dry, drink plenty of fluids.

Over-use of vocal cords can result in trauma and damage, affecting your voice. Polyps, cysts and vocal nodules are all issues related to over-use of the vocal cords in adults. Allergies and acid reflux can also contribute to throat and voice problems. Resting and treating these issues can help to preserve your voice.

Most hearing, speech and language problems can be avoided, especially if issues are identified and treated early.

Fortunately, it is May, and May is Better Hearing Month!
