What Are the Best Hearing Aids for Severe Hearing Loss?

Traditional hearing aids are an effective treatment for many people with hearing loss. Yet, certain people with severe hearing loss receive little or no benefit from conventional hearing aids. Someone in that frustrating situation may ask me or one of my colleagues what the best hearings aids are for their severe hearing loss. When our evaluation determines traditional hearing aids just aren’t working for someone, the best devices for that person may be cochlear implants instead of traditional hearing aids.


What Cochlear Implants Do

Although both hearing aids and cochlear implants are electronic devices, they work quite differently. A hearing aid makes sounds louder. A cochlear implant sends signals to your auditory nerve. Your brain takes those signals in as the sensation of sound. Cochlear implants are not a cure for hearing loss.


How a Cochlear Implant Works

A cochlear implant has an internal portion that is surgically implanted beneath your skin that’s behind your ear. The device also has an external section that goes behind your ear. The outer piece has a microphone to pick up sound and a sound processor to turn sound into digital signals. A transmitter sends the signals to the receiver that’s been implanted. The receiver sends signals to electrodes that have also been implanted. The signals stimulate the auditory nerve. Your brain receives the signals as sound.


Who Can Get Cochlear Implants

  • Cochlear implants may be the right option for people who:
  • Are adults or children who are at least 12 months old
  • Have severe or profound hearing loss in both ears
  • Have tried hearing aids with little or no improvement
  • Do not have medical conditions that could make surgery dangerous


We like children to get their implants as early as possible. Children have the most success with cochlear implants when they receive them before their natural period of language development. For adults, cochlear implants usually work better for individuals who could speak before they began experiencing hearing loss.


Scheduling a diagnostic appointment with us is the way to find out if you’re a good candidate for implants. During the diagnostic appointment, one of our audiologists determines whether you need cochlear implants. Our audiologist can also explain the next steps in the process.


What to Expect During Cochlear Implant Surgery

I’m aware even the word surgery is frightening for some people. Hopefully, a few facts about cochlear implant surgery will alleviate those fears. Cochlear implant surgery is a routine procedure that’s been performed in the United States for decades. It’s an outpatient procedure, which means you get to go home the day of the surgery. You’ll receive general anesthesia to keep you in a sleep-like state during the surgery. It takes the surgeon about four hours to put the implants in both ears.


We have established a partnership with Associates in ENT to provide cochlear implant surgery at our Chattanooga office. If you or your child struggle with severe hearing loss and traditional hearing aids haven’t helped, click here to schedule a diagnostic appointment.

Hearing Loss and Cardiovascular Health: A Vital Connection The inner ear depends on a rich network of healthy blood vessels to deliver the oxygen and nutrients necessary for hearing. Conditions that impair cardiovascular function—including hypertension, atherosclerosis, and other vascular disorders—can compromise this delicate system, increasing the risk of hearing loss. Emerging research continues to demonstrate a strong association between cardiovascular disease and auditory dysfunction, highlighting the importance of recognizing hearing loss as a potential indicator of broader vascular health. At Johnson Audiology, we view hearing care as an important extension of cardiovascular health. Through early detection and collaborative patient management, we help identify hearing changes that may support more comprehensive, whole-person care.

Understanding the Auditory Effects of Cancer Therapy Cancer therapies have transformed patient outcomes, but some treatments can affect more than the disease itself. Certain chemotherapy agents, radiation therapy, and supportive medications have been associated with hearing loss, tinnitus, and balance disorders that may develop during or after treatment. As cancer survival rates continue to improve, preserving quality of life has become an increasingly important part of comprehensive care. Recognizing treatment-related hearing changes early allows patients and providers to better manage their long-term health and communication needs. At Johnson Audiology, we work alongside healthcare providers to monitor hearing throughout the cancer care journey. Early evaluation, ongoing monitoring, and intervention, when needed, can help patients maintain communication, independence, and quality of life before, during, and after treatment. If your oncologist does not mention hearing testing as part of standard treatment protocol, bring up the subject yourself and request a referral to Johnson Audiology. It is wise to get a hearing test before treatment begins, midway through, and months, or even years, later.

Ototoxicity: An Often Overlooked Clinical Consideration Many medications play a vital role in treating disease, but some also have the potential to affect hearing and balance. Known as ototoxicity, these medication-related effects can occur with certain antibiotics, chemotherapy agents, loop diuretics, salicylates, and other common prescriptions and over-the-counter therapies. Although not every patient experiences hearing changes, understanding who is at risk and recognizing early signs of ototoxicity can help minimize long-term complications and support better treatment decisions. At Johnson Audiology, we strive to inform patients so they can work with their health care provider in recognizing medication-related hearing changes. This allows patients to be proactive about seeking comprehensive hearing evaluations and ongoing monitoring when an ototoxic medication is part of a health regimen. Early detection of ototoxicity and steps to mitigate its effects can help preserve communication, improve quality of life, and support informed patient care throughout treatment.
