Sensorineural Hearing Loss in Wilmington & Southport, NC

What Is Sensorineural Hearing Loss?

Sensorineural hearing loss (SNHL) is the most common type of permanent hearing loss, accounting for the vast majority of all hearing loss cases in adults. It occurs when there is damage to the delicate hair cells inside the cochlea (the hearing organ of the inner ear), the auditory nerve, or both.

Unlike conductive hearing loss — which involves a blockage or mechanical disruption in the outer or middle ear — sensorineural hearing loss is rooted in the inner ear itself. Sound may physically reach the cochlea, but the damaged hair cells are unable to convert those sound waves into clear neural signals for the brain to interpret.

The result is hearing that feels muffled, distorted, or incomplete — especially when it comes to understanding speech in noisy environments.

At Excel Audiology in Wilmington & Southport, NC, Dr. Jason Rickman, Au.D. provides comprehensive diagnostic testing and personalized treatment plans for patients living with sensorineural hearing loss. While SNHL cannot be cured, modern hearing technology makes it highly manageable — and the sooner it’s addressed, the better.

How SNHL Affects Your Hearing

The inner ear contains thousands of tiny hair cells that respond to different sound frequencies. When these hair cells are damaged or destroyed — whether by age, noise exposure, or other causes — they do not regenerate. The damage is permanent.

This is why sensorineural hearing loss typically causes:

  • Difficulty understanding speech, especially in noisy settings
  • Hearing sounds but struggling to make out the words
  • High-pitched sounds becoming harder to detect first
  • The sense that people are mumbling even when they’re speaking clearly
  • Tinnitus (ringing, buzzing, or hissing sounds in the ears)
  • The need to turn up the TV or ask people to repeat themselves

Many people with SNHL report that volume isn’t the primary problem — it’s clarity. Turning things louder doesn’t always help because the distortion is happening at the level of the inner ear.

Common Causes of Sensorineural Hearing Loss

SNHL can develop gradually over time or occur suddenly. The most common causes include:

Age-related hearing loss (Presbycusis)

The gradual deterioration of hair cells over a lifetime is the leading cause of SNHL. It typically begins in the higher frequencies and progresses slowly. Most adults begin to experience some degree of age-related hearing loss by their 60s.

Noise-induced hearing loss (NIHL)

Prolonged or sudden exposure to loud sounds is the second most common cause of SNHL. Noise damages hair cells in the cochlea, and the damage accumulates over time. Occupational noise, firearms, concerts, and loud earphone use are common culprits.

Genetics

Some forms of SNHL are hereditary. If hearing loss runs in your family, your risk is higher.

Viral infections

Illnesses such as mumps, measles, meningitis, and certain forms of the flu can damage the inner ear.

Ototoxic medications

Certain medications are known to damage the inner ear, including some antibiotics (aminoglycosides), chemotherapy drugs, and high-dose aspirin. An audiologist can monitor your hearing when you are on these medications.

Head trauma

Injuries to the skull can damage inner ear structures or disrupt the auditory nerve.

Ménière’s disease

A condition of the inner ear involving fluctuating hearing loss, ear fullness, vertigo, and tinnitus.

Autoimmune inner ear disease

In rare cases, the immune system attacks the inner ear, causing progressive bilateral hearing loss.

Sudden sensorineural hearing loss (SSHL)

A rapid drop of 30 dB or more in hearing over 72 hours or less. This is considered a medical emergency. If you experience sudden hearing loss, seek care immediately — early treatment with corticosteroids may help recover some hearing.

Diagnosing Sensorineural Hearing Loss

A comprehensive audiological evaluation at Excel Audiology will determine whether you have SNHL, what type, and to what degree. Testing includes:

Speech audiometry

Evaluates how well you understand speech at various volumes. This is particularly important in planning hearing aid fittings.

Tympanometry

Assesses middle ear function to rule out a conductive component.

Pure-tone audiometry (audiogram)

Tests hearing sensitivity across a range of frequencies using both air and bone conduction. SNHL is confirmed when both air and bone conduction thresholds are equally reduced, indicating the problem is in the inner ear rather than the conductive pathway.

Acoustic reflex testing

Helps identify the site of the lesion (cochlea vs. auditory nerve).

Treatment Options for Sensorineural Hearing Loss

There is currently no cure for sensorineural hearing loss — once inner ear hair cells are gone, they cannot be regenerated. However, SNHL is highly manageable, and modern hearing technology has transformed the lives of millions of people living with this condition.

Hearing Aids

Hearing aids are the primary and most effective treatment for mild to moderately severe SNHL. Today’s devices are far more advanced than older generations — they are discreet, comfortable, and packed with features:

  • Directional microphones that reduce background noise and improve speech clarity
  • Bluetooth connectivity for streaming audio from phones, TVs, and other devices
  • Rechargeable batteries — no more fussing with tiny disposable batteries
  • AI-powered noise processing that continuously adapts to the listening environment
  • Tinnitus masking features for those who also experience ringing in the ears

At Excel Audiology, we fit hearing aids using real ear measurement (REM) — the gold standard for verifying that devices are programmed precisely to your hearing prescription. This ensures you’re getting the most out of your devices from day one.

Cochlear Implants

For individuals with severe to profound SNHL who do not benefit sufficiently from hearing aids, cochlear implants may be an option. A cochlear implant is a surgically implanted device that bypasses the damaged hair cells and directly stimulates the auditory nerve. Dr. Rickman can help evaluate whether you may be a cochlear implant candidate and coordinate a referral.

Audiological Rehabilitation

Adjusting to new hearing — whether after a diagnosis or after getting hearing aids — takes time. Our team provides ongoing counseling, follow-up care, and communication strategies to help you and your family maximize the benefits of treatment.

Protecting Remaining Hearing

If you have SNHL, protecting your remaining hearing is critical. We offer custom hearing protection solutions for noise-sensitive environments including the workplace, shooting ranges, and concerts.

Living With Sensorineural Hearing Loss

SNHL is not just a hearing issue — it affects communication, relationships, and mental health. Research consistently shows that untreated hearing loss is associated with:

  • Social isolation and withdrawal
  • Depression and anxiety
  • Cognitive decline and increased risk of dementia
  • Reduced job performance and earning potential
  • Strained relationships with family and loved ones

The good news: treating hearing loss has been shown to significantly reduce these risks. People who wear hearing aids report improved quality of life, stronger relationships, and greater confidence in social situations. And the earlier treatment begins, the more the brain retains its ability to process sound effectively.

When to Seek Help for SNHL

Don’t wait to get your hearing checked. The average person waits seven years from the first signs of hearing loss before seeking help — and in that time, the brain adapts to hearing less, making the adjustment to hearing aids more difficult.

You should schedule a hearing evaluation at Excel Audiology if you:

  • Frequently ask people to repeat themselves
  • Struggle to follow conversations in noisy settings
  • Turn the TV or radio volume up higher than others prefer
  • Experience ringing, buzzing, or hissing in your ears
  • Have a family history of hearing loss
  • Have had significant noise exposure in your work or recreational life
  • Notice any sudden or rapid change in your hearing

Frequently Asked Questions

In most cases, yes. Damaged inner ear hair cells do not regenerate. However, sudden sensorineural hearing loss may partially recover with prompt medical treatment. For chronic SNHL, hearing aids or cochlear implants can dramatically improve hearing and quality of life.

Age-related hearing loss (presbycusis) and noise-induced hearing loss are the two most common causes of sensorineural hearing loss in adults.

Yes. Hearing aids are the most effective and widely used treatment for SNHL. At Excel Audiology, we use real ear measurement to fine-tune your devices for maximum benefit.

Sudden SNHL is a rapid loss of 30 dB or more across multiple frequencies within 72 hours. It’s a medical emergency — seek care immediately. Early treatment with steroids may improve recovery.

Conductive hearing loss involves a physical blockage or problem in the outer or middle ear and is often treatable or reversible. Sensorineural hearing loss involves the inner ear or auditory nerve and is typically permanent, though very manageable with hearing technology.

Some causes can’t be prevented, but noise-induced hearing loss is 100% preventable with proper hearing protection. Regular hearing exams also help catch early changes before they worsen.
