What Is Sensorineural Hearing Loss?
Sensorineural hearing loss (SNHL) is the most common type of permanent hearing loss, accounting for over 90% of all adult cases. It occurs when the tiny hair cells of the inner ear (cochlea) or the auditory nerve that carries signals to the brain are damaged or deteriorate. Unlike conductive hearing loss which is often reversible with medical treatment sensorineural hearing loss is typically permanent.
The good news is that sensorineural hearing loss is highly manageable. With today’s advanced digital hearing aid technology, the vast majority of people with SNHL can achieve significant improvements in hearing, communication, and quality of life. At Broadwater Hearing Care, Dr. Susan E. Terry, Au.D., F-AAA has been helping St. Petersburg residents discover a better life through better hearing since 1988 with the expertise, technology, and genuinely personalized care that only a full-service independent audiology practice can provide.
Common Causes of Sensorineural Hearing Loss
Age-related hearing loss (Presbycusis) The most common cause of SNHL. The natural aging process gradually reduces the number of functioning hair cells in the cochlea. Most people begin to notice age-related hearing loss in their 50s and 60s, and it typically affects high-frequency sounds first which is why voices may sound muffled even when they seem loud enough. Untreated age-related hearing loss has been linked to cognitive decline, so seeking help early is one of the most important investments you can make in your overall health.
Noise-induced hearing loss Prolonged or repeated exposure to sounds above 85 decibels permanently damages inner ear hair cells. Unlike age-related hearing loss, noise-induced hearing loss can affect people of any age. St. Petersburg’s vibrant outdoor and waterfront lifestyle from boating and fishing on Tampa Bay to concerts at Tropicana Field, outdoor festivals, and lawn and power equipment use makes noise-induced hearing loss a genuine and ongoing concern for many residents. Broadwater Hearing Care offers custom hearing protection to help prevent this type of permanent damage.
Genetic and congenital factors Some forms of sensorineural hearing loss are inherited or present from birth. Early identification and intervention are critical for children with congenital hearing loss to support speech and language development.
Ototoxic medications Certain drugs including some antibiotics (particularly aminoglycosides), chemotherapy agents, loop diuretics, and high-dose aspirin can damage inner ear hair cells. If you are taking medications with known ototoxic potential, regular hearing monitoring is recommended. Dr. Terry can help you track any changes in your hearing over time.
Ménière’s disease An inner ear disorder characterized by episodes of vertigo, fluctuating hearing loss, tinnitus, and a feeling of fullness in the ear. Hearing loss associated with Ménière’s disease is typically sensorineural and may become permanent over time. Broadwater Hearing Care’s expertise in dizziness and tinnitus makes us well-positioned to address all aspects of this condition.
Sudden sensorineural hearing loss (SSHL) A rapid loss of hearing typically in one ear occurring over a period of 72 hours or less. This is a medical emergency requiring immediate evaluation. Prompt treatment with corticosteroids can improve recovery outcomes. If you experience sudden hearing loss, contact Broadwater Hearing Care immediately at (727) 205-0134.
Viral infections Certain viruses, including mumps, measles, and meningitis, can cause sudden or progressive sensorineural hearing loss.
Acoustic neuroma A benign tumor on the vestibulocochlear nerve that can cause progressive hearing loss, tinnitus, and balance problems in one ear.
Symptoms of Sensorineural Hearing Loss
Because SNHL most often affects high frequencies first, the following symptoms are particularly characteristic:
- Difficulty understanding speech, especially in noisy environments, even when sounds seem loud enough
- Speech sounding muffled or unclear
- Trouble distinguishing consonants “s,” “f,” “sh,” and “th” sounds become hard to differentiate
- Difficulty following women’s and children’s voices compared to men’s lower voices
- Ringing, buzzing, or hissing in the ears (tinnitus) often accompanies SNHL
- Need to increase television or radio volume
- Asking people to repeat themselves frequently
- Withdrawing from conversations or social situations due to listening fatigue

How Is Sensorineural Hearing Loss Diagnosed?
A comprehensive hearing evaluation at Broadwater Hearing Care distinguishes sensorineural hearing loss from other types through a combination of:
Pure-tone audiometry — tests hearing sensitivity across a range of frequencies using the latest diagnostic technology to produce a complete picture of your hearing health
Bone conduction testing — if bone conduction and air conduction results are equally reduced, this confirms the hearing loss is sensorineural rather than conductive
Speech recognition testing — measures how clearly you understand speech at amplified volumes, which directly guides hearing aid selection and programming
Medical history review — identifying risk factors, noise exposure history, medication use, and family history to inform your personalized care plan
Dr. Terry brings some of the deepest diagnostic expertise in St. Petersburg, and she takes the time to explain your results clearly and honestly so you leave your appointment understanding exactly what is happening with your hearing and what your best options are.
Treatment and Management Options
Hearing Aids Hearing aids are the primary and most effective treatment for sensorineural hearing loss. Modern digital hearing aids do far more than simply make sounds louder they analyze and process sound in real time, suppressing background noise, enhancing speech clarity, and adapting automatically to different listening environments.
Unlike chain and big-box providers, Broadwater Hearing Care offers hearing devices from all major manufacturers giving Dr. Terry the flexibility to truly personalize your care based on your hearing needs and your budget. Whether you need a discreet invisible-in-canal device or a powerful behind-the-ear system, we will find the right fit. We are also happy to assist patients who purchased their hearing aids elsewhere and need expert fitting, programming, or repair support.
Brain Hearing Hearing is not just about your ears it is about your brain. Broadwater Hearing Care’s Brain Hearing approach recognizes that your brain plays a central role in how you process and understand sound. Modern hearing aids trained to support brain hearing can reduce listening fatigue and significantly improve speech understanding, especially in noisy environments.
Cochlear Implants (Referral) For individuals with severe to profound sensorineural hearing loss who do not benefit sufficiently from hearing aids, cochlear implants may be an option. Dr. Terry can assess your suitability and coordinate a referral to the appropriate specialist.
Assistive Listening Devices Amplified telephones, TV streaming accessories, personal amplifiers, and alerting devices can supplement hearing aids and improve daily communication in specific listening situations.
Tinnitus Management Many people with sensorineural hearing loss also experience tinnitus the persistent ringing, buzzing, or hissing that can disrupt sleep, focus, and everyday life. Addressing the underlying hearing loss with hearing aids, particularly those with built-in tinnitus therapy features, frequently reduces tinnitus perception significantly. Broadwater Hearing Care provides dedicated tinnitus relief services for patients throughout St. Petersburg and Pinellas County.
Earwax Management Earwax buildup can compound hearing difficulties on top of existing sensorineural loss. Broadwater Hearing Care provides professional earwax management to ensure any conductive component is addressed and your hearing aids if fitted can do their job properly.
Hearing Protection If noise exposure has contributed to your hearing loss, protecting the hearing you have left is just as important as treating what has already been affected. Broadwater Hearing Care offers custom hearing protection for work, recreation, and any environment where your ears are at risk.
The Importance of Early Intervention
Research consistently shows that the sooner hearing loss is identified and treated, the better the outcomes for hearing clarity, brain health, and social connection. Untreated hearing loss has been directly linked to cognitive decline, dementia, depression, anxiety, and social isolation. The brain adapts to sound deprivation over time, and prolonged untreated hearing loss can make it harder to readjust to amplified sound even after hearing aids are fitted.
Broadwater Hearing Care has dedicated a page specifically to the relationship between hearing loss and your overall health because we believe treating your hearing is about far more than just hearing better. It is about protecting your brain, your relationships, and your quality of life for the years ahead.
