The Sound Void: How Hearing Loss Sneaks Up on You

When you come to your first appointment with us, we encourage you to bring a companion, someone who spends a lot of time with you. Why is that? Because they’re able to give us a different perspective on your hearing loss. In fact, your companion probably noticed your hearing loss — and how it was affecting you — before you did.

But how is that possible if you’re the one with hearing loss?

How Sound Works

To begin with, it helps to understand how sound works. Most people think hearing loss is a question of volume. But that’s only part of the story. Sound is a combination of frequency (also called pitch) and intensity (also called loudness).

Frequency

Frequency measures how fast (or how frequently) a sound wave vibrates. High frequency means a high pitch, like the notes on the right side of a piano, and low frequency means low pitch, like the notes on the left side of a piano.

Intensity

Intensity measures loudness. A whisper has low intensity, and a shout has high intensity.

Frequency and Intensity Together

Each sound is a combination of these two qualities.

A baby screaming has high frequency and high intensity.
A man shouting has low frequency and high intensity.
The sound of leaves rustling has high frequency and low intensity.
A rumble of thunder has low frequency and high intensity.

The Sound Void®

Knowing how sound works helps us understand Sound Voids. We use the term Sound Void to refer to any moment lacking in clarity. Sound Voids have a lot to do with why your companion probably picked up on your hearing loss before you did.

Sound Voids happen all the time: Allergies or a cold affect your ears, leading to increased chance of misunderstanding what people say. Even a buildup of earwax can lead to an increase in Sound Voids.

But Sound Voids are also common with noise-induced or age-related hearing loss. Early on in these types of hearing loss, when someone speaks to you, you miss the high-frequency sounds, such as s, sh, c, ch, p, f, and h. These sounds help you identify words. With those sounds missing, “cat” could be mistaken for “hat” and “pickle” for “fickle.”

With this type of Sound Void, the intensities aren’t the problem — it’s the frequencies. In other words, you can hear people speaking just fine, but sometimes you misunderstand them.

At this early stage, what is actually a hearing loss truly seems to you like a momentary lack of clarity. You assume someone mumbled a little, or there are more people than usual at the restaurant. Loved ones probably think the same thing.

The Sound Voids Increase

But as time goes on, the Sound Voids become more frequent, and those closest to you start to notice subtle signs: You turn up the volume on the TV or radio, you need statements repeated more often, and you get tired more easily while socializing in public venues.

Your companion, by this point, has started to wonder if you have hearing loss. Because you’ve developed coping skills, you probably haven’t truly realized how it’s affecting you or your loved ones.

The Sound Voids Take Over

Eventually, enough of your hearing is damaged that you’re not just missing frequencies — intensity is now a problem, too. You’re more likely to miss the low-frequency sounds of speech, the ones that provide volume, such as o, i, and j.

At this point, your companion has probably wondered aloud whether you have hearing loss, and you’ve started to realize how your hearing loss is affecting others. This is when many people consider getting their hearing tested.

The Hearing Evaluation

This is why the companion is such a key part of the hearing evaluation: They’ve witnessed the early Sound Voids, the gradual behavior changes, how your hearing loss affects those around you, and your realization that you might have hearing loss. Their outside observations are an important complement to your internal observations.

Hitting the Water? Don’t Forget Your Swimmers’ Earplugs for Ear Protection!

in Hearing Health, Hearing Protection

You’ve packed the swimsuits, floats, safety vests, caps, goggles, kids, and snacks for a summer afternoon at the lake or neighborhood pool, but what about the earplugs?

These small accessories can make a big difference in keeping the good times going during family fun in the water. Before you go, here are four things to know about swimmers’ earplugs:

1. They Help Protect Against Ear Infection
  
  Ears and moisture don’t always mix. Otitis externa, an outer-ear infection also known as “swimmer’s ear,” is typically caused by bacterial or fungal growth when the skin in the ear canal potentially becomes irritated from activities such as swimming. Though treatable, the condition can lead to temporary hearing loss and other problems, so prevention matters. Using quality, properly inserted earplugs helps keep the water — and the threat of infection — out of your ears.

1. They Can Be Off the Shelf or Customized
  
  It’s always nice to have options, and swimmers’ earplugs are no exception. They come in disposable, reusable, and custom-fit varieties and can be made from silicone or putty. Off-the-shelf earplugs are often readily available at local drugstores, but your local audiologist can create a better-fitting, washable set tailored to your unique ears. Take heed: Swimmers’ earplugs are not the same as hearing-protection earplugs and should be used only for water protection.

1. They’re Not Just for Swimmers
  
  Earplugs can be your best friend when it comes to protecting your ears in water, but did you know they’re not just for swimming? That’s right! Folks who work outside in the heat all day, for example, can also use earplugs to keep the sweat away, so it’s good to have a couple extra pairs at home, the job site, or other convenient storage spots. Remember: If your ears have a chance of getting wet, protective earplugs are one of your best bets.

They’re a Solution for Adults and Children

You might think swimmers’ earplugs are just for grown-ups. Not so fast! Water in the ears can also pose a problem for kids, who are typically more vulnerable to ear infections than adults. Inserting earplugs before a swimming session or at bath time, keeping your child’s ear canals clean, and drying the ears after any amount of time in the water or other moist environment can help curb the risk of infection. And remember: Always use clean hands when inserting earplugs into your or your child’s ears.

Hearing Loss: One More Reason Not to Smoke

How Are Smoking and Hearing Loss Related?

in Comorbidity, Hearing Health

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!

Is Weight Connected to Hearing Loss? Studies Say There’s a Connection.

in Comorbidity, Hearing Health, Hearing loss

Is Weight Connected to Hearing Loss?

Studies about weight often concern its relation to overall health. Common connections include weight and the risk for or prevalence of heart disease, diabetes, and sleep apnea, to name a few. One topic that doesn’t get as much attention is the connection between weight and risk for hearing loss. But is there a connection?

To understand how weight affects hearing, you need to know about something tiny but important in your inner ear: the hair cell.

The Hair Cell

Your brain doesn’t understand sound waves. Tiny, hair-like structures in your inner ear, called hair cells, translate sound waves into a language — electrical signals — your brain understands. It sends those signals to your brain through the auditory nerve, and your brain interprets the signals as sound information.

Care and Feeding of Your Hair Cells

Hair cells need plenty of oxygen, which they get from strong, rich blood flow. If you have poor circulation, your hair cells don’t get sufficient nourishment. This leads to cell damage or death. Your body can’t repair hair cells — the damage is done, leaving fewer opportunities for sound information to reach your brain. Hearing loss due to damaged or destroyed hair cells is permanent.

Weight and Blood Flow

The more fat tissue in the body, the harder the heart has to work to get blood where it needs to go. Despite the extra work and increased blood pressure, the blood doesn’t actually move through the body as easily. It’s harder for the blood to reach areas farther away from the heart, such as the tiny blood vessels in your inner ear. Again, the poorer the blood flow, the less nourishment for your hair cells.

Is the Belly the Culprit?

Results from a John Hopkins School of Medicine study reported that improvement in blood flow is directly related to a reduction in excess belly fat. How? As belly fat is lost, the arteries regain their ability to expand, allowing blood to flow freely. The greater the reduction of belly fat, the stronger the recovery of healthy blood flow.

So it stands to reason that reducing belly fat would lead to better hearing. And results from the Harvard Nurses’ Health Study support that reasoning: They found a direct correlation between amount of belly fat and risk of hearing loss. They also found that exercise protected against hearing loss.

Are Portable Music Players Putting Your Ears at Risk?

in Hearing, Hearing Health, Hearing loss, Tips & Tricks

Turn the Music Up, Dude — But Not Past 85 Decibels

You probably use your tablet or smartphone often to stream music, TV shows, or movies. In fact, many websites these days auto-play videos regardless of whether you want them to.

Smartphones, tablets, and other types of portable music players (PMPs) are now commonplace, as are earbuds and headphones. But if your PMP is turned up too loud while wearing earbuds or headphones, you can damage your hearing quickly. Let’s look at why.

NIHL

This isn’t some new sports league — NIHL stands for noise-induced hearing loss, and it’s the second-largest cause of hearing loss worldwide.

You’re able to hear because of hair cells in your inner ear. These cells convert sound signals to electrical signals and send them to your brain, where they’re interpreted as sounds. But loud sounds can actually damage or destroy your hair cells.

Every time a hair cell gets damaged, you lose a little bit of your ability to hear, and that damage can’t be repaired. The result is NIHL.

How Headphones Hurt Your Hearing

Navigating noise is all about the decibels (a measure of sound pressure). You’re safe if the sound in question stays below 85 decibels (dB); above that, you’re in the action zone — protect your ears or risk hearing damage.

For comparison:

A clothes dryer = 60 dB
No need for hearing protection
A gas lawn mower = 91 dB
Exposure can damage hearing in 2 hours
A tractor =100 dB
Exposure can damage hearing in 15 minutes
A chain saw = 112 dB
Exposure can damage hearing in less than 1 minute

Some PMPs can generate 112 dB — in other words, if you like to listen to your PMP at full volume, you’re likely pumping a chain saw’s worth of noise at your ears from centimeters away.

Why Protecting Your Hearing Matters

Hearing loss is connected to overall health in surprising ways. It’s been linked to depression, cardiovascular disease, diabetes, cognitive decline, dementia, and other health concerns.

But it’s not just a concern for later in life: One study found that any degree of hearing loss early in life increases a child’s risk for language and learning problems.

Considering that one study of PMP use in 9-to 11-year-olds reported that 9 in 10 children and teens use some form of audio-streaming device for education or recreation, PMPs pose a considerable hearing health risk at all ages.

Indeed, that same study found that 14 percent of the children had measurable hearing loss. In addition, if a child listened to their PMP only once or twice a week, it doubled their chances of hearing loss compared to children who didn’t use a PMP.

What You Can Do

Enforce the 60/60 rule. Don’t turn the volume of your PMPs up past 60 percent of full volume, and turn the device off completely after listening for 60 minutes so your ears can have a break.
Use headphones instead of earbuds. With earbuds, you pick up background noise, which often leads to turning up the volume on the PMP to hear the audio better. Headphones that surround the ear keep the background noise to a minimum, allowing you to leave the volume at or below 60 percent. Even better, invest in noise-canceling headphones.
If you must use earbuds, make them in-ear earbuds. With these earbuds, the earpiece sits inside the ear canal, rather than just outside it. The sleeve around the speaker blocks out background noise and keeps your audio from escaping the ear canal.
Use the sound limiter built into the PMP. Many devices allow you to limit how loud the volume goes, or the device has a built-in alert telling you you’re risking hearing damage by pushing the volume higher.
For kids, get volume-limiting headphones. Though there are many child-friendly options for headphones that will keep the volume from going over 85, it’s best to read up on whichever pair you choose to buy. Research by Wirecutter found that, of more than 30 brands tested, almost half were not effective at keeping the volume below 85 dB.

Osteoporosis May Nearly Double Risk of Sudden Hearing Loss

No Bones About It: Osteoporosis May Nearly Double Risk of Sudden Hearing Loss

What does osteoporosis, a potentially debilitating disease affecting some 10 million Americans and 2 million Canadians, have in common with conditions such as heart disease, diabetes, chronic kidney disease, dementia, and other selected conditions? It can go hand in hand with hearing loss.

More specifically, at least one study links osteoporosis to a nearly doubled risk of sudden sensorineural hearing loss, a disease that can touch people of all ages around the globe but primarily affects those in their 50s and 60s.

What Is Osteoporosis?

Osteoporosis is a disease characterized by weakened bones that are more vulnerable to breakage. It occurs when the normal process of old bone being replaced by new bone slows down, putting the person at greater risk of serious problems such as hip, wrist, and spine fractures.

Though some osteoporosis risk factors such as gender, age, race, and family history can’t be helped, a few preventive tactics can make a difference in keeping bones healthy, strong, and more resistant to becoming fragile, weak, and brittle:

Avoid tobacco use and excess drinking.
Adopt a regular exercise regimen approved by your doctor.
Maintain a healthy body weight, steering clear of too few or too many calories.
Eat healthfully, being sure to include protein, calcium, vitamin D, and other nutrients in your diet.

Does Osteoporosis Cause Sudden Hearing Loss?

Scientists aren’t necessarily ready to say that osteoporosis actually causes sudden sensorineural hearing loss, but studies have long reported a relationship between the two. More recently, researchers in Taiwan sought to quantify the risk of sudden hearing loss in osteoporotic patients. They published their results in the June 2015 edition of The Journal of Clinical Endocrinology & Metabolism.

The investigators, who studied a random representative sample of 1 million participants in Taiwan’s National Health Insurance program, found that those with osteoporosis had a 1.76-fold risk of experiencing sudden sensorineural hearing loss. Patients at seemingly greatest risk: adults 50 and older, women, and — possibly — those with hypertension and osteoporosis.

QUICK FACTS ABOUT SUDDEN SENSORINEURAL HEARING LOSS

Relatively common and typically referred to as “sudden deafness” or “SSHL”
Involves rapid hearing loss in an instant or over several days
Usually develops in one ear rather than both
May occur together with dizziness or ringing in the ears
Requires immediate help for greatest effectiveness of treatment
Common treatment includes steroid therapy, but some cases resolve on their own
Often has unknown cause, but common culprits include head injury, ototoxic drugs, infectious disease, circulation problems, thyroid disorders, and other selected conditions

What Can You Do?

Take good care of your bones — and your ears. A causal relationship between osteoporosis and sudden sensorineural hearing loss might not yet be conclusive, but one thing is clear: If you or a loved one has osteoporosis or is experiencing listening difficulties, it’s important to get a hearing check.
