The Role of Online Hearing Tests

You can do a lot of things online these days. Even test your hearing.

Though it is not a replacement for a full diagnostic hearing session with an audiologist, an online hearing test can be useful. Especially in the case of someone just starting to admit to hearing loss who may need a little nudge to get them off the fence and into a professional’s office.

One aspect of online hearing tests that is very useful is the ability to take them regularly and create a long-term record of hearing function. This can alert someone to a consistent initial decline in their hearing and produce a dynamic that gets them to seek help. Likewise, a temporary hearing issue caused by allergies or illness might be confirmed when hearing function returns to “normal” over the course of testing.

When recovering from an exposure event involving very loud noise—an accident, attending a concert, or forgetting to use ear protection—a series of online tests can confirm that the damage was temporary and hearing is returning to normal (if that is the case).

There are two types of tests available, calibrated and non-calibrated.

Non-calibrated tests are less sophisticated and use volume level to track the ability to hear in loud environments and the basics of speech recognition. Calibrated tests track hearing across different frequencies and create an audiogram, a graph that visualizes the ability to hear at different pitches.

Most major brands of hearing aids have online hearing tests as part of their web pages, including Oticon and Signia.

Ears Are Not Immune to Allergic Reactions

For the unlucky, the end of summer brings on a new bout of allergies. Usually, this means itchy eyes and a runny nose, but don’t be surprised if your ears get into the act as well.

Your ears, like other parts of the body, are just as susceptible to an overly aggressive immune system; one that has decided that the pollen from some plant that’s made its way into your nasal passage is an enemy that must be eradicated. Allergic reactions are basically your immune system making sure you know it’s doing its thing.

And since your ears are linked—via the Eustachian tubes—to the throat (and therefore the rest of the nasal cavity), it is not unusual for that immune-system chain reaction to get into the inner ear.

This can result in tissue inflammation and excessive fluid buildup, both of which can have a noticeable effect on hearing, especially if the surfaces of one or both eardrums are impacted. Allergies can also create excessive earwax production, which can clog up the ear canal.

In fact, the Eustachian tubes themselves—which are relatively tiny and provide a vital service by regulating air pressure within your head—can get clogged up themselves and throw off the mechanism that helps us maintain our balance.

Anything that helps with the more common allergy symptoms— over-the-counter antihistamines—will probably also help clear out the ears and alleviate any hearing issues that have developed. But if issues linger, then consult a medical professional who can prescribe more powerful prescription medications.

Keep Your Ears Dry In The First Place

If you’re someone who makes swimming a part of your life—whether in a pool or natural body of water—then investing in some swimming earplugs might be a wise choice.

The kinds of ear infections that swimming makes more likely—there’s a reason they call it “swimmer’s ear”—can derail your summer and become a chronic nuisance.

There are a few things you can do to curtail the chance of coming down with a case of the summertime blues. Remembering to not “dry” your ears with friction by using a towel, Q-tip, or even a finger is a good start. Doing so will lead to abrasions on the walls of the ear canal, which is where bacteria can lodge and get started infecting your ear.

Also, be aware that if you use a hearing aid, removing it when you go swimming and reinserting it into a wet ear afterward will bring the same risk of creating conditions rife with infection possibilities.

And don’t assume that only swimming in chlorine-treated water will not put you at risk. Public pools are a great place to pick up a case of swimmer’s ear.

That’s why a pair of custom-molded swimming earplugs are your best line of defense. They will create a watertight seal that keeps the water—and thus waterborne bacteria—out of your ear canal. Shaping them to the contours of your ear is an important step in creating a tight seal and the best protection.

This is the best way to defend your ears and make sure you don’t get derailed this summer—or any time of year—by an ear infection.

Don’t Let Your Ears Suffer From The Music

The contemporary summer music festival scene isn’t synonymous with the hard-of-hearing generation—they went to Woodstock—but hearing loss should be on the younger set’s radar.

That’s because nearly one-fourth of Americans between 18 and 44 are believed to already be dealing with hearing loss issues. Between the rise of earbuds, the increase of high-volume media in public spaces, and the general loudness of modern life, there is a clear trend of hearing loss working its way down from the older generation.

With music festivals back on the agenda for the summer of 2021—after being scrubbed last year—now’s a good time to think about protecting your ears if you plan on once again diving into live music this summer. The damage done by extended exposure to excessive sound is rarely treatable; it’s permanent and can accumulate over time until hearing aids are really the only remedy.

One thing to remember, especially if you’re going to be onsite for hours on end, is that letting your ears take some breaks from loudness will lessen the risk of damage. Like most parts of your body, overuse will lead to problems.

But the best protection is earplugs. Generic ones are good, custom-fitted ones better.

If going to shows is an aspect of your life you’ve been looking forward to getting back into, and you expect to see a lot of shows to make up for lost COVID time, then investing in some professionally-fitted ear molds might be a wise move. They’ll provide a high level of protection while not interfering with sound quality, ensuring that your enjoyment of concerts for years to come does not come at the price of your long-term hearing health.

Hearing and Lingering COVID

Many of our patients are looking for some sense of long-term impact of COVID, asking themselves how long do COVID symptoms last? And although broad in nature, for the overwhelming majority of us who will get COVID, most will overcome the symptoms of the illness within several days.

However, Long-haul COVID is a condition that has slowly become more recognized by both the medical profession and the public at large. It covers a wide range of symptoms that people who recovered from bouts of COVID-19—even mild cases—found themselves dealing with for months on end.

The most serious of these are extreme fatigue and problems breathing, degraded brain function, and heart inflammation that can be a serious threat for cardiac arrest (this last has included some world-class athletes).

A few symptoms related to hearing have also been reported, especially tinnitus, which is a constant high-end ringing sound. A few cases of sudden, direct hearing loss have cropped up and bouts of vertigo are another area of concern.

Tinnitus is not only the most commonly reported hearing-related side effect of COVID, but also the area that has received the most study. A recent report in Frontiers in Public Health entitled “Changes in Tinnitus Experiences During the COVID-19 Pandemic” followed the experience of over 3,000 people who had tinnitus and then came down with COVID. It found the about 40 percent of them reported that their condition worsened. For some it was a brief experience, for others it extended much longer.

Given that—though it’s hard to believe—COVID-19 has only been with us for less than two years, continuing the monitor patients is the only path forward in order to learn more about the long-term impact.

As the report states: “Those who have had COVID-19 should be monitored for changes in hearing-related problems, such as initiation or worsening of tinnitus. There is most likely also a cohort of patients who experienced an onset of tinnitus during this period and who will need access to clinical care for their tinnitus.”

The good news is that some COVID long haulers have found that their symptoms have lessened once they were fully vaccinated.

Now That You Can Fly Somewhere Again, Make It a Pleasant Experience

It looks like the coming months could fill our calendars, and the sky, as commercial airliners take people on long-delayed vacations and business trips as COVID restrictions are lifted. If it’s been a while, it’s a good time to remember that flying can put a real beating on your ears and that taking precautions is wise.

Dealing with changes in air pressure that can’t be avoided—especially during takeoffs and landings—is usually something that your body can handle. Planes are designed to compensate for this and your ears (in close coordination with the eustachian tubes) can handle the rest.

But … if you’re clogged up from a cold, allergies, or other reason something could go awry. The eustachian tubes, which are the passageway between the ear canal and throat, need to be fully functional to deal with the rapid change in air pressure. Even at full capacity, ear-popping can be unpleasant. If they’re clogged up, then actual damage to the eardrum is possible, which is known as barotrauma.

Basically, the surface of the eardrum is drawn inward too fast and hard, which can lead to tearing or rupture. Not good.

If you’re feeling congested before a flight, taking a decongestant is advisable. Likewise, specialized earplugs designed to counter air pressure changes are also a good idea (they also protect the ears from the loudness of jet engines).

Even good old-fashioned gum chewing works, since the chomping motion forces the eustachian tubes to be more malleable, creating create better airflow from the inner ear.

You might have a better trip if you take these precautions and a visit to a hearing professional pre-flight could also be a good choice!

Take Hearing Loss Seriously

There are a host of reasons to take hearing loss seriously and then take steps to counteract it, including the obvious ones like increasing quality of life and better maintaining social connections and work skills.

But another more ominous one is the increasing evidence that untreated hearing loss can adversely impact the onset of dementia.

According to the website of Johns Hopkins Medicine, one of the world’s premier medical institutions: “In a study that tracked 639 adults for nearly 12 years, Johns Hopkins expert Frank Lin, M.D., Ph.D, and his colleagues found that mild hearing loss doubled dementia risk. Moderate loss tripled risk, and people with a severe hearing impairment were five times more likely to develop dementia.”

The risk can’t be much clearer than that.

Although the causal link is not fully understood, the suspicion is that the lack of input from the auditory system actually causes parts of the brain to atrophy. Basically, not only is the complex functions that translate external sound waves into internal hearing via electrical impulses the way we hear, but it’s also great exercise for the brain. When it is curtailed, the ultimate receiver—the brain—degrades due to a lack of activity.

Another theory is that the dwindling ability to communicate well with others leads to social isolation and loneliness, both of which have also been linked to increased risk for the onset of dementia.

Regardless of the particulars, the obvious takeaway is that hearing loss should be treated as soon as possible. With modern hearing aids, treating it is now routine and should not be delayed. And testing hearing should join other passages of middle age—like colon cancer screening, cholesterol profiles, and shingles vaccine boosters—as part of a holistic approach to health.

Giving the Gift of Hearing at the End of a Long Year

The lockdown year we’ve all just lived through has been one of sacrifice, loss, and resolve for us all. We’ve realized that we’re all in the same boat and answered the call with a recommitment to charitable giving.

Back in December, we carried out our Gift of Hearing event, our third annual. It features open nominations of people who—because of their public service or unique circumstances—not only have hearing issues but also are deserving of a gift of premium hearing aids.

Like the United Way’s Personal Item Supply Drive we’re currently supporting with drop boxes at our office until the end of March (please contribute personal items like toothpaste, toothbrushes, shampoo, soap, razors that will be directed to food pantries and community shelters), the “Gift of Hearing” event pays it forward in these challenging times.

Given the realities of 2020, we couldn’t choose just one deserving recipient, so we picked two.

Our first recipient was Gary, who has lived with hearing loss for all of his life and has handled all of the challenges that entails. Hearing aids are vital to him and, as a winner of our Gift of Hearing event, this lifeline to fully participating in daily life stays accessible to him.

The second winner was Donald, a military vet who not only deals with hearing loss issues but also has undergone major heart surgery. Through it all, he’s continued working and giving back to the community.

We’re proud to have found two such deserving recipients.

The Brain Needs to Hear

One of the best reasons to stay on top of your hearing health and seek treatment for any issues with it is the link between hearing and cognitive performance. It has become increasingly clear in recent years that “losing” one’s hearing is often intertwined with weakening of one’s mind.
Several scientific studies have found that hearing loss, especially when untreated, can speed up changes to the brain that come with aging. This includes it literally shrinking—and untreated hearing loss can make this worse.

A 2019 study published in Alzheimer’s & Dementia, based on research by a team from Brigham and Women’s Hospital that spanned eight years, found that hearing loss was associated with a higher risk for cognitive deterioration.

“Our findings show that hearing loss is associated with new onset of subjective cognitive concerns which may be indicative of early stage changes in cognition. These findings may help identify individuals at greater risk of cognitive decline,” stated lead author Sharon Curhan, MD.
These most recent findings come after previous studies also pointed to changes in the brain that were driven, at least in part, by hearing loss.
One such study in 2014, carried out by Johns Hopkins Medicine and the National Institute on Aging, used MRI images of participants in the Baltimore Longitudinal Study of Aging — which has been active since 1958 — for analysis. It found that early intervention to limit hearing loss could be key to preventing permanent changes to the brain’s structure that, once occurring, cannot be reversed.

It seems clear that, in addition to just making life easier by enhancing one’s hearing, treating hearing issues will very likely have positive long-term effects on overall quality of life—and long-term health.

Bluetooth Pushes the Boundaries of What Hearing Aids Can Be

Although it isn’t exactly new technology, Bluetooth’s role in the new world of hearing aids should still be appreciated. The last decade has seen an explosion in the ways devices can communicate with one another wirelessly — which opens up access to the Internet — and hearing aids are most definitely part of this high-tech parade.

By creating a very localized wireless network, Bluetooth makes possible the knitting together of any combination of devices. TVs can communicate with computers, smartphones with refrigerators, doorbells with audio systems — and hearing aids with all the above.

With the computing power that modern hearing aids entail, this creates a wealth of possibilities. Audio from entertainment platforms can be streamed directly to a hearing aid, which cuts down on any distractions from other sounds that might be in the area. Being able to focus on specific sound sources in such situations has always been a challenge for hearing aid users.

The same is true for telephone conversations, which have also traditionally been a challenge. Now smartphones, via Bluetooth, eliminate the need to hold a phone to one’s ear to hear. The sound is streamed directly into the hearing aid. There are even wireless microphones that can be used to create hands-free phone calls.

Finally, with dedicated apps installed on any linked device, a hearing aid can be controlled and adjusted without the need to take it out of one’s ear and fumble with small knobs or buttons. Everything can be done by hand with a touchscreen or mouse, making obsolete what was until recently one of the most annoying aspects of having a hearing aid.

What Bluetooth has unleashed has brought a new day for hearing aid users.
