COVID-19 and Hearing Loss

What preliminary research is revealing

We all have many self-care choices we make daily: wearing a seatbelt, eating a healthy diet, exercising, attending to spiritual well-being, getting an annual physical, meditating, and the list goes on. The reality is that each day, we may face new obstacles in maintaining our personal well-being as well as encounter new ways that allow us to live life to the fullest. We have more resources and more technology available to us than at any other time in human history. So, when we are faced with new challenges, how do we approach our dedication to self-care? How do we adjust when the landscape around us is constantly changing? These certainly are appropriate questions during a year filled with upheaval as the entire world has been rocked by the COVID-19 pandemic. The current health crisis requires us to digest brand new or updated information quickly and make choices to mitigate risk to ourselves and those around us in order to stay safe and well.


Our knowledge about this strain of coronavirus seems to be increasing exponentially each week with information about how a person’s body is affected while the virus is active and after the person has recovered. Dr. Megan Johnson, audiologist and owner of Johnson Audiology, said, “Evidence continues to emerge showing the wide-ranging effects COVID-19 can have on the body’s organs and systems, and it is looking like our ears and sense of hearing may also take a hit from this monster of a virus.” Preliminary research is beginning to suggest that COVID-19 may have lasting negative impacts on neural and auditory pathways, which in turn can lead to hearing loss. 


So what does this have to do with self-care? Johnson Audiology’s Dr. Kari WIckstrom shared, “It is estimated that 48 million Americans have significant hearing loss with 22 million Americans exposed to dangerous levels of sound in the workplace. That’s a little more than 14% of the total population who can’t hear all of the sounds they once heard.” In addition, Americans wait an average of seven years before addressing hearing loss. Dr. Whitney Smith with Johnson Audiology noted, “That’s seven years of a gradually decreasing quality of life, increased risk of harm and hospital stays because of falls since balance is linked to inner ear health, frustration, loneliness. Plus, without the stimulus of sound, your brain ‘forgets’ how to hear, making it even harder to adjust to hearing aids when someone finally addresses hearing loss.” These statistics make it clear that when it comes to self-care, many people minimize hearing and hearing loss. Johnson Audiology’s Dr. Susan Porter observed, “Interestingly, the pandemic has shone a light on many people’s hearing loss, making it impossible to ignore. As we all don face masks to stay safe and compliant, those with hearing loss are forced to confront how much they were lip reading. Now that people’s mouths are covered, the person with hearing loss is really struggling.” So, in the midst of a global pandemic attributed to a virus that is showing no signs of slowing down, it becomes even more important to stay vigilant about addressing your physical self-care, including your hearing.


A group of people wearing face masks are sitting at a table.

Preliminary research is starting to be published. For example, in a recent study conducted at South Valley University in Egypt1, a group of patients who were asymptomatic and tested positive for COVID-19 were monitored for two weeks. They ranged in age from 20-50 and presented no known symptoms of the virus, nor did they have any known hearing loss prior to testing positive. This age group was chosen specifically to avoid those with age-related hearing loss. After the two weeks of testing, it was found that the hair cells inside the ear’s cochlea (the seashell-shaped structure that is part of the inner ear and allows us to hear) showed signs of damage, and response to high frequency sounds was significantly reduced. While this test group had no symptoms of the virus, it is important to note that there is still much to learn about the underlying effects of the virus being present in the body, even among those who are asymptomatic. 


In another case, a patient in Hannover, Germany was admitted to the hospital with symptoms of COVID-192. The patient was in the Intensive Care Unit for 13 days during his battle against the virus. Prior to contracting COVID-19, the patient was in good health and had no known hearing loss. After his treatment in the ICU, the patient presented as completely deaf on his right side and with profound hearing loss on his left side. MRI’s showed the patient had suffered from inflammation in and around the cochlea. This inflammation can lead to the cochlea becoming solidified like bone, no longer flexible and functioning. 


Additionally, in most cases of the treatment of symptoms and the effects of COVID-19, the drugs commonly used in fighting the virus can be toxic to the ear and/or the nerves connected to the ear. Doses of certain drugs are known to cause hearing loss and create complications throughout the ear and the functions that the ear provides. It is these drugs, however, that are necessary to treat the symptoms of many known viruses, like COVID-19, as well as various bacterial infections. 


Many unknowns exist with the presence of a new virus or disease, and it can take years to fully understand its origins and its lasting effects. In a time of so much uncertainty, but also so much emphasis on self-care, why not address your hearing loss now? Audiologist Darnell Scafe, with Johnson Audiology, suggested asking these questions: “Are there certain sounds that you have noticed you can’t quite hear as well as you used to? Do you find yourself frustrated in crowded situations because you are always asking people to repeat what was said? Are you struggling in public settings because people are wearing face masks, and you can no longer read their lips? She encouraged, “As the landscape of self-care and health care are ever-changing, why not change your approach to caring for your ears?”


Many things can affect our ears and contribute to hearing loss. They range from exposure to loud sounds, to side effects of drugs, or the emergence of a new strain of virus into our environment. And while many types of hearing loss are irreversible, technology continues to advance in ways that make hearing loss something that can be treated and hearing health improved. Dr. Johnson cautioned, “Don’t wait. Address your hearing loss at first onset so that you can enjoy years of sounds, conversations and being an active participant in your own life. Contact Johnson Audiology and begin a partnership with our team of audiologists that will put you on the path to healthy hearing.”

Like anything new in life, adjusting to hearing aids can take time and perseverance to achieve the best results. Yet many people are too quick to give up, not allowing the brain the chance to relearn how to hear or not giving themselves the opportunity to become accustomed to the use and maintenance of their devices. “We meet so many people who wait—who convince themselves their hearing is not ‘bad enough’ or that they can just get by. But untreated hearing loss quietly steals moments, connection, and joy. At Johnson Audiology, we understand the fear, the frustration, and the doubt. That is why we offer more than hearing aids—we offer compassion, answers, and a partner you can trust. You don’t have to do this alone. Let us help you hear your life again,” says Dr. Megan Johnson, audiologist and owner of Johnson Audiology. “Hearing aids should never be an experience where a person is fit with devices and then they never see their hearing care provider again. To ensure patient success, Johnson Audiology seeks to be a lifelong partner on a person’s journey to healthy hearing, someone who is there at every turn,” says Dr. Megan Johnson, audiologist and owner of Johnson Audiology. What are the most common reasons why people give up on hearing aids and why is it important to stick with it? Reasons why people might give up on hearing aids An adjustment period It is your brain that hears, not your ears. The ears transmit sound to the brain where it is interpreted. Dr. Johnson explains, “When a person’s brain has not been stimulated by sound because of hearing loss and then sound is restored with hearing aids, it can take some getting used to. For some people, it takes more than one appointment to get them up to full sound prescription, stair stepping up gradually to let the brain adjust. The brain’s capacity to do this is called neural plasticity .” Research by the University of Colorado Boulder’s Hearing Epidemiology and Research Diagnostic Laboratory has revealed that what the brain can experience impacts within weeks rather than years when hearing loss reaches a certain level. Dr. Johnson says, “The brain’s temporal lobe is where much of hearing and sound interpretation happens. Electroencephalogram (EEG), which is a medical test that measures the electrical activity of the brain, shows that in the presence of hearing loss, the brain will recruit areas assigned to other tasks—like vision—to compensate. The trouble is that this extra cognitive load can tax those areas. However, after treatment with hearing aids, brain recruitment is shown to reverse, partially or fully.” The adjustment period for hearing aids tends to be more seamless for those who have not been without sound for years and years. Dr. Johnson says, “I always encourage people to get their hearing checked when they first notice they are struggling. Sooner is always better.” An investment in quality of life People often make an investment in their health and well-being—for example, purchasing glasses, getting a knee replacement, straightening their teeth—and yet many relegate hearing to the backburner because of cost. Dr. Johnson says, “I’ve seen many patients struggle with hearing aids after buying inferior products in an attempt to save money. Without the guidance of a hearing care provider, even the best device can quickly become ineffective and frustrating.” Dr. Johnson encourages making hearing a priority and budgeting for your hearing health. Perceived benefits and ease of use Getting in the routine of putting hearing aids in each day and being diligent about regular cleaning and maintenance might be a challenge that some face and which deters them from being successful with their aids. “At Johnson Audiology, we offer a plan for regular in-office cleaning and maintenance, easing the task of upkeep for patients. Plus, our offices have dedicated walk-in hours that do not require an appointment. We are here to answer questions, make hearing aid adjustments, and much more as we seek to help people safeguard their investment in hearing technology and make the process easy and convenient.” Family attitudes and support When it comes to hearing aids, having a support system can be crucial to success. “In my 20 years as an audiologist, I have seen the immense benefits when a person’s family members show patience and support during the adjustment period with new hearing aids,” said Dr. Johnson. What about patients who do not have that familial encouragement? Dr. Johnson says, “We are your support system. That’s where our caring and professional audiologists, audiology assistants, and patient care coordinators can lend a helping hand. Success with hearing aids is our goal for every patient, so we promise to be there every step of the way.” Why is healthy hearing so important Hearing loss is a family affair The positive impact of treating hearing loss is often manifested most significantly through improved relationships with family and friends. Hearing loss leads to miscommunication. It can also cause mounting frustration as family members must constantly repeat every sentence. Dr. Johnson comments, “Living with the TV blaring can put a strain on others living in the same household. Untreated hearing loss can quietly tear at the fabric of your relationships. When words go unheard and conversations fade, love and connection start to suffer, and that pain is felt by all involved.” Healthy hearing can help the brain stay sharp and pliable For many years, researchers at Johns Hopkins University have been studying the relationship between hearing loss and dementia. While there is still much left to discover, increasingly scientists recognize healthy hearing as a key factor in maintaining a healthy brain and potentially decelerating the risk of dementia, like Alzheimer’s disease. Dr. Johnson says, “It seems logical that when certain areas of the brain are not stimulated by sound, they atrophy. In fact, research suggests an actual reduction in the physical size of the brain, especially in areas where sound processing and memory take place.” She goes on to say that “while there are many risk factors that individuals cannot control about the effects of aging on the brain, hearing is definitely one that can and should be addressed.” Healthy hearing keeps a person engaged in life Humans are social beings. Since hearing loss can impair effective communication, it is not difficult to understand how it also could lead to social isolation, which can cause increased anxiety and depression. “Conversely, addressing hearing loss can keep a person engaged in life and connected to family and friends,” Dr. Johnson says. Falls and other health risks The ears have two main functions. Hearing is one that most of us learn as youngsters, but the ears also play a major role in helping a person maintain their balance and knowing where their body is in space. “The fluid, or endolymph, in the ear’s semicircular canals is what helps a person do things like stand up from a seated position without falling, walk a straight line, and not run into a door frame when turning a corner into a room,” says Dr. Johnson. In the presence of hearing loss, the reduction in acoustic signals impairs a person’s ability to process spatial information and can mean a higher risk for falling. In turn, falling can lead to broken bones and other injuries and a cascading effect of hospital stays and loss of independence.
