Sensorineural Hearing Loss in Simi Valley, CA

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 Ascent Hearing Center in Simi Valley, Dr. John Malan, Au.D. and our team are dedicated to helping you stay connected to life’s cherished experiences — starting with a thorough, personalized hearing evaluation.

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.

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. Simi Valley and the greater Ventura County area offer an active outdoor and recreational lifestyle — from motorsports and shooting sports to concerts and live events — making noise exposure a real and ongoing concern for many residents. Ascent Hearing Center 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. Our team sees patients of all ages.

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.

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.

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 Ascent Hearing Center right away at (805) 262-8955.

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 social settings due to listening fatigue

If any of these sound familiar, you don’t have to keep settling for a muted world. A comprehensive hearing evaluation at Ascent Hearing Center is the first step toward hearing better.

How Is Sensorineural Hearing Loss Diagnosed?

A comprehensive hearing evaluation at Ascent Hearing Center distinguishes sensorineural hearing loss from other types through a combination of:

  • Pure-tone audiometry — tests hearing sensitivity across a range of frequencies to determine the degree of hearing loss
  • 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

Dr. Malan takes the time to walk you through your results in plain language, discuss your listening lifestyle and goals, and build a treatment plan that fits your life — not a one-size-fits-all solution.

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.

At Ascent Hearing Center, we carry all major hearing aid brands and can fit every style from discreet invisible-in-canal devices to powerful behind-the-ear systems. Every fitting is personalized by Dr. Malan to ensure comfort, clarity, and a natural listening experience. We also offer affordable hearing aid options and financing to make sure cost is never a barrier to better hearing.

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. We 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 environments.

Tinnitus Management Many people with sensorineural hearing loss also experience tinnitus — the persistent ringing, buzzing, or hissing that can interfere with sleep, concentration, and daily life. Addressing the underlying hearing loss with hearing aids, particularly those with built-in tinnitus therapy features, frequently reduces tinnitus perception significantly.

Hearing Protection If noise exposure is a contributing factor to your hearing loss, protecting the hearing you have left is just as important as treating what has been lost. Ascent Hearing Center offers custom hearing protection for work, recreation, and any situation 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 linked to cognitive decline, depression, increased risk of falls, and withdrawal from the social experiences that make life meaningful. 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.

Don’t wait. A free hearing assessment at Ascent Hearing Center is the easiest first step you can take.

Frequently Asked Questions

Can sensorineural hearing loss be reversed? In most cases, it cannot be reversed because the inner ear hair cells do not regenerate. However, it can be effectively managed with hearing aids, and researchers are actively investigating regenerative therapies for the future.

Will hearing aids restore my hearing to normal? Hearing aids do not restore normal hearing, but they significantly improve your ability to hear and understand speech in most environments. The improvement in quality of life for most users is substantial — many patients tell us conversations feel effortless again for the first time in years.

Is sensorineural hearing loss the same as nerve deafness? These terms are often used interchangeably, though sensorineural hearing loss can involve damage to the hair cells of the cochlea, the auditory nerve, or both.

Do you offer financing for hearing aids? Yes — Ascent Hearing Center offers financing options so that getting the hearing care you need is always within reach. Ask our team about available plans when you come in for your evaluation.

What hearing aid brands do you carry? We carry all major hearing aid brands and styles. Dr. Malan will recommend the best option based on your specific hearing loss, lifestyle, and preferences — never a one-size-fits-all approach.
