March 2022: World Hearing Day

March 7, 2022

“To hear for life, listen with care.”


March 3 was World Hearing Day! I meant to have this blog posted that day, but other things got in the way. However, I decided to post it late because this blog is all about educating the public of all the services Audiologists can provide. One of these services is education and supply of custom and non-custom hearing protection devices. We also take impressions that patients can send to manufacturers themselves for custom devices for all sorts of activities.


With over a billion young people at risk of avoidable hearing loss due to recreational sounds, the focus of this year will be on hearing loss prevention through safe listening.


The key messages of this year’s focus are:

  • It is possible to have good hearing across the life course through ear and hearing care.
  • Many common causes of hearing loss can be prevented, including that which is caused by exposure to loud sounds.
  • Practicing safe listening can mitigate the risk of hearing loss associated with recreational sound exposure.


In 2021, WHO released the World Report on Hearing, highlighting the increasing number of people living with and at risk of hearing loss. The report highlighted noise control as one of the seven key H.E.A.R.I.N.G interventions and stressed the importance of mitigating exposure to loud sounds. The WHO is calling upon governments, industry partners and civil society to raise awareness for and implement evidence-based standards that promote safe listening.


In the last thirteen years as a practicing Audiologist, here is what I have learned from my patients. I have seen more cases than I would like to admit, where irreversible damage has occurred due to exposure to loud sounds without the use hearing protection. Many of these cases involve firearms. Not only does the noise exposure cause permanent hearing loss, but it has also caused tinnitus, hyperacusis, and chronic pressure/fullness in the ears in some cases.


More frequent noise exposures for longer periods of time can cause a slower degradation of a person’s hearing if appropriate hearing protection is not used. This can also lead to tinnitus and other issues with the auditory system. Research has shown blast exposures that cause traumatic brain injury have been linked to auditory issues including hearing loss, central auditory processing disorders, vestibular impairment, and tinnitus.

I counsel my patients daily on the importance of protecting our hearing from noise. There are many over the counter products that work well if used properly. However, the most important feature of any type of hearing protection is the fit. If the device does not fit a person’s ear properly, it will not provide the amount of noise reduction that may be listed on the product. I often hear people complain about the fit of these over-the-counter products and how uncomfortable they become after extended periods of use.


TYPES OF HEARING PROTECTION DEVICES WE OFFER (CUSTOM & NON-CUSTOM):

  • Industrial Hearing Protection
  • Firearm Protection (for all types of shooting/hunting activities)
  • Motorsport Protection
  • Sleep Plugs
  • Musician’s Plugs (various types for musicians or avid concert attendees)
  • Musician’s In-the-Ear Monitors
  • Swim Plugs (not protecting our hearing from noise, but protecting it from exposure to water)
  • AirPod/Earbud Molds (making earbuds more secure and comfortable)
  • Pilot Molds


This list may not include every single option we have access to, so if you need a particular type of device, please call the office and let us know.

If you need to use hearing protection frequently due to occupational or recreational activities, call our office today to discuss the best options for you.

In the last five years, 4 Bridges Audiology owner, Dr. Courtney Guthrie, has continued to add services to become the most comprehensive audiology practice in the Chattanooga area. “The addition of evaluations for dizziness, balance issues, and vertigo has been the most beneficial to our patients. Prior to us starting this two years ago, patients had to drive to Knoxville or Nashville to get this type of test. It is a service that Chattanooga has needed for a long time,” said Dr. Guthrie. Dr. Dana Notaro joined 4 Bridges Audiology in May as the practice’s Vestibular Audiologist, focusing on helping patients find the relief they need from dizziness or vertigo and preventing fall related injuries.

Dana Notaro, Au.D., CCC-A, F-AAA As we celebrate Audiology Awareness Month, it's essential to focus not only on hearing health but also on the often-overlooked aspect of balance: the vestibular system. Many people are unaware that dizziness can be related to issues in this system, which is crucial for maintaining our balance and spatial orientation. Let’s dive into what vestibular testing involves and why awareness of dizziness is so important for your overall health. What Is the Vestibular System? The vestibular system, located in the inner ear, plays a vital role in helping us maintain our balance and navigate our environment. It works closely with our visual and proprioceptive systems to keep us oriented. When this system is functioning properly, we can move around confidently. However, issues in the vestibular system can lead to dizziness, vertigo, and balance problems. Common Causes of Dizziness Dizziness can arise from various factors, including: Vestibular Disorders: Conditions like Benign Paroxysmal Positional Vertigo (BPPV), Meniere’s disease, and vestibular neuritis. Inner Ear Infections: These can disrupt balance and cause feelings of dizziness. Medication Side Effects: Certain medications can impact your balance and cause dizziness. Neurological Disorders: Conditions such as migraines or multiple sclerosis can also affect the vestibular system. Why Is Dizziness Awareness Important? Being aware of dizziness is crucial for several reasons: Quality of Life: Chronic dizziness can severely impact your daily activities, work, and social interactions. Safety: Dizziness can increase the risk of falls, particularly in older adults. Recognizing and addressing these symptoms can help prevent injuries. Underlying Conditions: Dizziness can be a symptom of underlying health issues that may require treatment. Early detection can lead to better management. What to Expect During Vestibular Testing If you're experiencing dizziness, your audiologist may recommend vestibular testing to evaluate your balance system. Here’s what you can expect: Comprehensive Assessment: Your audiologist will take a detailed history of your symptoms, including when they occur and their severity. Balance Tests: You may undergo various tests, such as: Electrophysiology Testing: This involves measuring the electrical activity in the vestibular system to assess how well each pathway is functioning, helping to identify any abnormalities. Videonystagmography (VNG): This test measures eye movements to assess the vestibular system's function in different scenarios. Rotary Chair Testing: This evaluates how your vestibular system responds to rotational movements, providing insight into how well your balance system is functioning. Caloric Testing: This test uses warm and cold air in your ears to see how well your vestibular system is working in each ear separately. Vestibular Head Impulse Test (vHIT): This checks how well your eyes and head work together during quick movements by isolating each of your 6 semicircular canals. Results and Recommendations: Based on the tests, your audiologist will discuss the results and develop a tailored plan to address your symptoms. This may include vestibular rehabilitation therapy, lifestyle changes, or referral to a specialist. Tips for Managing Dizziness If you’re experiencing dizziness, here are a few tips to help manage it: Stay Hydrated: Dehydration can exacerbate dizziness, so drink plenty of water. Limit Sudden Movements: Stand up slowly and avoid rapid head movements to minimize dizziness. Practice Balance Exercises: Simple exercises can strengthen your balance and coordination. Seek Support: Don’t hesitate to reach out to your audiologist if you have concerns about dizziness. This Audiology Awareness Month let’s not overlook the significance of our vestibular system. Awareness of dizziness and understanding the importance of vestibular testing can empower you to take control of your balance and overall health. If you or someone you know is experiencing dizziness, schedule an appointment with your audiologist to discuss your symptoms and explore your options. Together, we can work towards a safer, more balanced future!
