Auditory Neuropathy & Hearing Loss in Grand Rapids, MI

Auditory neuropathy is a rare type of hearing loss seen in both children and adults in Grand Rapids, Michigan. It occurs when sound enters the inner ear normally, but the signals from the inner ear to the brain are disrupted or distorted. This condition is sometimes called a form of “neural” or “nerve” deafness.

There is currently no cure for auditory neuropathy, and the exact cause is often unknown. Both ears are usually affected, and hearing loss can range from mild to severe.

In West Michigan, people with auditory neuropathy are often evaluated and treated through major health systems such as Corewell Health (formerly Spectrum Health), Trinity Health Grand Rapids, Metro Health – University of Michigan Health, and Mercy Health, as well as local audiology clinics.

How Auditory Neuropathy Affects Hearing

In auditory neuropathy, some structures in the ear may work normally, but the information gets distorted on its way to the brain. This can lead to very inconsistent hearing.

Many people with auditory neuropathy in Grand Rapids report that they:

  • Can hear sounds but have difficulty understanding speech, especially in noisy places (like busy restaurants, school cafeterias, or crowded events).
  • Notice that sounds may fade in and out.
  • Experience normal hearing levels on some tests, but still struggle with speech clarity (speech perception).

Symptoms can fluctuate. A person may have days when their hearing seems better and other days when it seems worse. Over time, hearing may:

  • Improve
  • Deteriorate
  • Or remain stable

There is no reliable way to predict how an individual’s hearing will change.

Symptoms of Auditory Neuropathy

Symptoms vary from person to person, but may include:

  • Mild to severe hearing loss in one or both ears (usually both)
  • Sounds that seem to fade in and out
  • Difficulty understanding spoken words, especially in:
    • Background noise (e.g., Grand Rapids restaurants, school classrooms, workplaces)
    • Large group settings
  • Normal or near-normal hearing on some tests, but poor speech perception
  • Worsened speech understanding in noisy environments compared with quiet ones

Many of these symptoms can also be caused by more common types of hearing loss, which is why specialized testing is important.

How Normal Hearing Works

To understand auditory neuropathy, it helps to know how hearing normally works:

  1. Outer ear

    • The visible part of the ear funnels sound waves into the ear canal.

  2. Middle ear

    • Sound waves hit the eardrum, causing it to move.
    • Tiny bones in the middle ear (ossicles) amplify this movement.

  3. Inner ear (cochlea)

    • The amplified vibrations reach the cochlea, a spiral-shaped organ.
    • Tiny hair cells inside the cochlea sense these vibrations and convert them into electrical impulses.

  4. Auditory nerve and brain pathways

    • The electrical impulses travel along the cochlear nerve.
    • The cochlear nerve joins with the balance nerve to form the eighth cranial nerve.
    • Signals then travel through the auditory pathways in the brainstem (at the base of the skull, acting as a bridge between the brain and spinal cord).
    • The brain interprets these signals as sound, and we “hear.”

In auditory neuropathy, any of the following may be damaged or not working properly:

  • Hair cells in the inner ear
  • The connections between hair cells and the cochlear nerve
  • The cochlear nerve itself
  • The auditory pathways in the brainstem

Because of this, sounds may reach the ear but become distorted before they reach the brain.

Causes and Risk Factors

The exact cause of auditory neuropathy is often unknown, but several factors are thought to contribute.

Possible Causes

  • Damage to hair cells in the inner ear
  • Problems at the connection between hair cells and the cochlear nerve
  • Damage to the cochlear nerve
  • Damage to the auditory pathways in the brainstem

Risk Factors in Children

Children in Grand Rapids and across Michigan may be at higher risk of auditory neuropathy if they have:

  • Health problems during pregnancy (in utero)
    • Reduced oxygen supply to the fetus
    • Certain infections or complications
  • Health problems at birth, such as:
    • Premature birth
    • Severe jaundice
    • Low birth weight
  • Exposure to certain medications that can affect hearing (ototoxic drugs)
  • Other neurological or genetic disorders, including:
    • Charcot–Marie–Tooth disorder
    • Friedreich’s ataxia
  • Family history of auditory neuropathy or similar hearing problems

Because some children with auditory neuropathy have affected family members, this suggests a genetic component in some cases.

Adults may develop auditory neuropathy due to neurological conditions, medication side effects, or unknown causes.

Diagnosis of Auditory Neuropathy in Grand Rapids

If you or your child has signs of hearing loss in Grand Rapids, your primary care provider may refer you to:

  • An ear, nose and throat (ENT) specialist / otolaryngologist
  • An audiologist (hearing specialist)

Major health systems such as Corewell Health, Trinity Health Grand Rapids, and Metro Health all offer diagnostic hearing services, and the Kent County Health Department and Grand Rapids Public Health can help connect families with local resources.

Common Diagnostic Tests

Diagnosis typically includes a combination of tests:

1. Auditory Brainstem Response (ABR)

  • Small electrodes are placed on the ears and head.
  • The person listens to a series of sounds.
  • The test records brain wave patterns in response to sound.
  • People with auditory neuropathy often show little or no response on ABR, even when the inner ear appears to be working.

2. Otoacoustic Emissions (OAE)

  • A tiny microphone is placed in the ear canal.
  • It measures the faint sounds (emissions) produced by hair cells in the cochlea.
  • In many people with auditory neuropathy, these hair cells still function, so OAEs may be normal.

3. Other Hearing Tests

  • Speech recognition tests (understanding spoken words)
    • These may be done in both quiet and noisy environments.
    • People with auditory neuropathy usually perform much worse in background noise.
  • Additional neurological tests may be used to rule out other conditions (such as multiple sclerosis) that can cause similar symptoms.

Because Michigan’s cold winters can increase the frequency of ear infections and other seasonal illnesses, it’s important to distinguish common, temporary hearing issues from more complex conditions like auditory neuropathy.

Treatment Options for Auditory Neuropathy

There is no cure for auditory neuropathy. The condition is highly variable, and treatments that help one person may not help another. There are no tests that can reliably predict which treatment will work best, so patients and their hearing specialists often need to experiment with different options.

In Grand Rapids, treatment and management are typically coordinated through ENT specialists and audiologists at systems such as Corewell Health, Trinity Health Grand Rapids, Metro Health, and Mercy Health, as well as independent audiology practices.

1. Cochlear Implants

  • A cochlear implant is a surgically implanted device that directly stimulates the nerves of the inner ear.
  • These devices can help many people with auditory neuropathy improve their understanding of speech, even if traditional hearing aids were not helpful.
  • Surgery and follow-up programming are available at major hospital systems in Grand Rapids.

2. Hearing Aids

  • Hearing aids amplify sounds.
  • While they can be very helpful for many types of hearing loss, adults with auditory neuropathy often do not find hearing aids very effective, because the main problem is not loudness but clarity of the signal.
  • Some children and adults may still benefit, especially when combined with other strategies.

3. Frequency Modulation (FM) Systems

  • FM systems use a microphone worn by a speaker (such as a teacher) and a receiver and headset worn by the listener.
  • They help amplify the speaker’s voice over background noise, which can be especially useful in:
    • Grand Rapids classrooms
    • College lecture halls
    • Work meetings
  • These systems can be very helpful for children in local schools, especially during noisy winter months when indoor activities increase and background noise levels rise.

4. Other Supportive Strategies

  • Environmental modifications (reducing background noise at home, school, or work)
  • Preferential seating (sitting closer to the speaker)
  • Use of assistive listening devices in public venues (some theaters, churches, and community centers in Grand Rapids offer hearing assistance systems)

Communication Approaches for Children and Adults

Because auditory neuropathy is so variable, there is professional debate about the best communication approach, especially for children.

For Children

Two main approaches are often discussed:

  1. Sign Language–Based Approach

    • Teach the child sign language as a primary or early communication method.
    • Ensures the child has a reliable way to communicate, even if hearing does not improve.

  2. Listening and Spoken Language Approach

    • Provide hearing technology (hearing aids, cochlear implants, FM systems).
    • Offer intensive support to help the child learn to listen and speak.

Many professionals now recommend a combined approach:

  • Introduce sign language early for immediate communication.
  • Provide hearing technology and spoken language exposure in case hearing improves or technology is effective.

Why Early Spoken Language Exposure Matters

  • Exposure to spoken language is important in case the child’s hearing improves, stays stable, or responds well to treatment.
  • Early language input—spoken, signed, or both—is critical for brain development, especially in the first few years of life.

In Grand Rapids, families can access support through:

  • Pediatric audiology and ENT services at local hospital systems
  • Early intervention programs through Kent ISD and local school districts
  • State and local programs coordinated with the Michigan Department of Health & Human Services and Kent County Health Department

For Adults

Adults who already have spoken language skills may benefit from:

  • Speechreading (lip reading) training
  • Communication strategies for noisy environments (e.g., choosing quieter restaurants, facing the speaker, asking for written follow-up)
  • Use of assistive listening devices and workplace accommodations

Living With Auditory Neuropathy in Grand Rapids

With proper diagnosis and support, many people with auditory neuropathy in West Michigan can:

  • Succeed in school, work, and social situations
  • Use a combination of technology and communication strategies
  • Access community resources and support groups

Because Grand Rapids experiences long, cold winters and frequent indoor activities, background noise in homes, schools, and public spaces can be significant. This can make speech understanding even more challenging for people with auditory neuropathy, so extra attention to classroom acoustics, home noise levels, and assistive technology can be especially helpful.
