What is Conductive Hearing Loss

 

Have you ever tried having a conversation with someone on the other side of a closed door? You probably end up raising your voice and straining to hear them. Open that door and suddenly it’s as easy as pie. Your voice and theirs flows unimpeded, back and forth between the two of you. For people living with conductive hearing loss, having a simple conversation with anyone can feel like trying to talk through a great, big closed door! The problem is much the same – those all-important sounds aren’t flowing freely.

 

This is what should happen when you’re hearing normally…

 

When someone says hello, the sound of their voice travels through the air and into your outer ear – that’s the visible, fleshy part of your ear and the ear canal that travels into your head. The next stop for those sounds is to pass through to the eardrum, a thin film that separates your outer ear from your middle ear. Then, yes, you guessed it, after hitting the eardrum, sounds go on into the middle ear. This part of your ear has 3 tiny bones that transmit the sounds, which are now vibrations, into the inner ear. The inner ear is where the sounds are converted into electrical signals that travel to the brain via a nerve. Now it’s time for your brain to take over, process the sounds, and, like magic, you hear that hello. All of this happens in the blink of an eye.


 This is what happens when you have conductive hearing loss…


 

Someone says hello, the sound of their voice travels into your outer ear and that’s when the problems can start. Conductive hearing loss prevents sounds getting through into the inner ear, either blocking their passage in the outer ear or the middle ear. The worse the conductive hearing loss, the less sound gets through, which means you may not hear that hello at all.

 

What causes conductive hearing loss?


 

There are lots of different reasons you may experience conductive hearing loss, with earwax being at the top of the list as it builds up and blocks the ear canal. Infections of the ear canal or middle ear, ruptured or perforated eardrums, cysts, tumors, and diseases that affect the structure of the middle ear can all cause conductive hearing loss too. Many of these conditions are treatable with medication and/or surgery and can be completely resolved. In cases where conductive hearing loss can’t be reversed, hearing can still be improved using hearing aids.

 

What are the signs of conductive hearing loss?


 

If you’re struggling to understand conversations in person or on the phone, are finding you need to turn the TV up, or have a sense that even your own voice sounds different, then you may have conductive hearing loss. It could be that you can hear less through one ear than the other. You may even feel pain or pressure in one or both ears.

Untreated hearing loss is changing your brain

By Jan Hollingsworth • May 16, 2024
Research reveals that hearing loss actually rewires your neural pathways Your Amazing Brain Your brain is an amazing organ! This wrinkly, reddish-pink mass weighs about the same as your two-slice toaster, tipping the scales at about three pounds. Acting as a master control center, your brain enables every thought, breath, eye blink, heartbeat, movement—everything—that happens in your body. Rivaling the world’s most powerful supercomputer, your brain can download, process, and react in milliseconds to the tidal wave of information coming from your eyes, skin, nose, tongue, and ears. Neuroplasticity and Your Sense of Hearing Researchers have discovered that the human nervous system—made up of the brain, spinal cord, and a complex network of nerves—has incredible capacity to modify itself, both in function and physical structure. This is called neural plasticity . Dr. Megan Johnson, audiologist and owner of Johnson Audiology explains, “Neural plasticity is going gangbusters in a child’s brain as the child develops and matures into adulthood. Based on years of brain research, we also know that the adult brain is far from being fixed. It, too, changes and adapts when you learn new information or skills or as a response to stress, hormonal fluctuations, drug interactions, injury, and much more.” Dr. Johnson also relates that “your brain displays neuroplasticity when you experience hearing loss.” By measuring brain waves using an electroencephalograph, or EEG, scientists have studied how the brain of a person with hearing loss functions compared to a person with normal hearing. The results are both fascinating and sobering as studies reveal that, in those with hearing loss, the portion of the brain devoted to hearing becomes reorganized. This can be true even with early-stage, mild hearing loss, and the process happens quickly, often in months rather than years. The Hearing Center of Your Brain and Beyond What is actually happening when this takes place? Your brain has a right and a left hemisphere and six major lobes. Think of your frontal lobe as your brain’s boss, where executive functions like decision making, emotion and impulse control, and planning occur. Your temporal lobe, which contains the auditory cortex, is doing the heavy lifting when it comes to interpreting sounds and assigning those sounds meaning. The temporal lobe processes speech and language, and it is where initial learning of new information takes place, which is the first step for logging that information into memory. Dr. Johnson goes on to relate, “When the delicate infrastructure of your ear has become damaged through noise exposure, infection, etc. leading to hearing loss, your auditory cortex cries out to your frontal lobe, saying ‘Help! Help! I’m not receiving any sound to process, so I feel lost.’ The frontal lobe ‘boss’ jumps to attention, and your occipital lobe, responsible for processing vision and touch, takes over the areas in which hearing is normally processed. In other words, your other senses seek to compensate for the deficit due to the loss of your sense of hearing.” Amazing, right? So, where’s the rub? Picture a car assembly line; each worker has an assigned task. One day, the worker who installs the windshields is absent, and the worker who attaches the rearview mirrors is assigned double duty, and a duty that was not part of job training. It is easy to see how the worker left juggling both jobs is compromised, and a car might slip through minus a rear view mirror. Similarly, the areas of your brain that are being taxed to make up for a lack of hearing are overloaded and less able to do their assigned responsibilities. “This explains why so many of my patients with hearing loss relate feeling exhausted and frustrated after a big family gathering—where multiple talkers and sounds must be interpreted—rather than happy and invigorated by the experience. We call this listening fatigue ,” states Dr. Johnson. Additionally, when left untreated long enough, researchers point to the brain’s reorganization due to hearing loss as a significant correlation with dementia. Hearing Technology and Your Brain “But here's the great news!” Dr. Johnson says. When a person is fit with hearing aids or a cochlear implant and sound is restored, the brain has the ability to adjust back—partially or completely—to proper function. How swiftly that happens often depends on how long the hearing loss went untreated and is why she encourages patients to treat hearing loss sooner rather than later. “Here is what I tell patients who are downplaying the importance of hearing: If you won’t treat your hearing loss for the sake of your ears, do it for your brain!”

Move from the Gunbarrel Road office to a new and larger office will allow Johnson Audiology to help even more people in the Chattanooga region

By Jan Hollingsworth • January 9, 2024
Johnson Audiology is pleased to announce that the practice will be moving one of its Chattanooga area offices from its current location on Gunbarrel Road to a new location at 6830 Lee Highway. The move will take place January 15. “We are extremely excited to be re-locating to a much larger space later this month,” Dr. Megan Johnson, founder and owner of the award-winning practice, says. “About a year ago, we realized that we needed more room to meet the needs of our growing patient base so we could help even more people with hearing loss. We sought a place that would allow us to stay in the East Brainerd/Hamilton Place area so that the office would still be conveniently located for patients. Our Hixson office will remain at 5617 Highway 153, Suite 203 and is also being upgraded with a second sound booth and beautiful new decor. These two strategically located offices mean that we can continue to serve patients who live east and west of the Tennessee River.” Dr. Johnson says that when she identified the building on Lee Highway, she knew it was an ideal site for this next growth leap. “Our company culture is anchored on the premise of always offering an exceptional patient experience,” she says. “Thanks to our wonderful family of Johnson Audiology patients, we have outgrown our current office and have found the perfect location for offering the best care to even more of our Chattanooga neighbors.” The new location offers many positive features that will benefit patients: The office is conveniently located off Lee Highway in the area between Shallowford Road and Hickory Valley Road, directly behind Dr. Keith B. Dressler’s orthodontic practice. It is a stand-alone office that is not shared with any other businesses. The building is more than 4,000 square feet, which is double the space of the current office on Gunbarrel Road. The added square footage will accommodate a spacious patient welcome and reception area, three sound booths for hearing testing, and a private area for patient check-out. The building has exam rooms for four full time audiologists and an audiology assistant, a large front desk area, and a sizeable lab for hearing aid maintenance and repair. The office has ample space for the practice’s growing Cochlear Implant (CI) Program with a dedicated sound booth and exam area just for CI patients. The building design allows for easy circular patient flow throughout the office. The building has a dedicated, 20-space parking lot just for Johnson Audiology patients and additional parking for Johnson Audiology staff. Dr. Johnson mentions that the building was a non-medical office previously, so updates were needed to bring it up to par for a bustling hearing health care clinic. It currently is being remodeled, and the parking lot resurfaced. “We have plans to transition to the new building by January 15 with some final touches to the office’s aesthetics continuing through the spring,” she says.  Dr. Johnson wishes to assure folks that measures are in place to alleviate disruption to the service patients receive during this time and thanks patients in advance for their continued support and understanding during the transition. “The new office is going to be incredible!” she says. Initial correspondence has been delivered to patients about the move. Dr. Johnson says, “Patients who have appointments scheduled in early January or those who need walk-in service for hearing aid maintenance and supplies from now until January 15 should continue visiting the Gunbarrel Road location.” Dr. Johnson says, “In February, we will invite our friends and neighbors in the Chattanooga community to an open house celebration, where we will do an official reveal of the new space!” Johnson Audiology has been faithfully serving the citizens of Chattanooga since the practice opened its doors on October 1, 2009. “As we prepare to celebrate our 15th anniversary this year, the new office location on Lee Highway and the upgrades to the Hixson office are evidence of our commitment to patients.” Dr. Johnson goes on to say, “Chattanoogans have named Johnson Audiology Best of the Best in the category of Favorite Audiologist and Hearing Aid Clinic for 11 years straight. And they consistently name Johnson Audiology in the top three in the category of Best Customer Service among all Chattanooga businesses. We seek to live up to those accolades daily!” Dr. Johnson concludes, “One of our patients, Mr. Van Tenpenny, recently had this to say about us: ‘My visit to Johnson Audiology has been life changing! After decades of hearing loss, I am able to hear normal conversations in any environment.’ It is our highest ideal to be here for Mr. Tenpenny and the thousands of other patients like him who prioritize their hearing for the best quality of life.” Do you want to get on the road to healthy hearing?
