Understanding Hearing Aids

Hearing aids are small electronic devices designed to amplify sound for children with hearing loss. These sophisticated instruments help children develop speech and language skills, participate in social activities, and achieve their full potential in academic settings. Unlike simple amplifiers, modern hearing aids use digital technology to process sounds, making speech clearer while reducing background noise.

The journey of hearing aid technology began in the early 20th century when the first electric hearing aids replaced ear trumpets and mechanical devices. These early devices were large and cumbersome. The invention of the transistor in 1947 revolutionized hearing aid design, making devices smaller and more practical. By the 1990s, digital hearing aids emerged, offering superior sound quality and programmability.

Today's pediatric hearing aids represent decades of technological advancement. They incorporate artificial intelligence, wireless connectivity, and sophisticated sound processing that automatically adapts to different environments. This evolution has transformed hearing aids from simple amplifiers into intelligent medical devices that significantly improve quality of life for children with hearing loss.

Purpose and Medical Use

Hearing aids serve a critical role in treating sensorineural hearing loss, which occurs when the tiny hair cells in the inner ear or the hearing nerve itself are damaged. They are also used for conductive hearing loss, where sound cannot efficiently travel through the outer or middle ear. For children, the primary purposes include:

Primary Functions:
  • Supporting speech and language development during critical early years
  • Enabling communication with family members, teachers, and peers
  • Facilitating learning by making classroom instruction audible
  • Improving social interaction and emotional well-being
  • Preventing developmental delays associated with hearing loss

Children learn language primarily through listening. Every conversation they hear, whether directed at them or overheard from others, contributes to their language development. Hearing aids ensure children receive this essential auditory input during waking hours, maximizing their opportunities for learning and development.

Types of Hearing Aids

Behind-the-Ear (BTE) Hearing Aids

BTE hearing aids are the most common type used for children. All electronic components are housed in a plastic case that sits behind the ear, connected to an earmold or dome that fits in the ear canal. These devices are suitable for almost all types and degrees of hearing loss, from mild to profound.

Why BTE is Preferred for Children: BTE hearing aids are durable, easy for parents to handle, have tamper-resistant battery compartments, and can accommodate growing ears by simply replacing the earmold while keeping the main device. The earmold needs to be remade as the child grows, typically three to four times per year for infants and young children.

Receiver-in-the-Ear (RITE) Hearing Aids

RITE hearing aids look similar to BTE devices but have the receiver (speaker) located inside the ear canal rather than in the case behind the ear. This design allows for a smaller device and reduces feedback whistling. However, they are typically not suitable for very young children or those with severe to profound hearing loss.

In-the-Ear (ITE) Hearing Aids

ITE hearing aids are custom-made to fit entirely in the outer ear bowl. These are generally not recommended for young children because they need to be completely remade as the ear grows, requiring the child to be without hearing aids during the remaking process. They are more appropriate for older children and teenagers whose ears have finished growing.

In-the-Canal (ITC) and Completely-in-Canal (CIC) Hearing Aids

These smaller devices fit partially or completely inside the ear canal. While less visible, they are not typically used for children due to their small size making them difficult to handle, limited power for severe hearing loss, and frequent need for replacement as the ear grows.

Bone Conduction Hearing Aids

These specialized devices transmit sound through vibrations to the bones of the skull, which then stimulate the cochlea. They are worn on a headband or attached to an implanted abutment. Bone conduction hearing aids may be recommended for children who have conductive hearing loss, structural abnormalities of the ear, chronic ear drainage, or cannot wear traditional ear-level hearing aids.

Common Hearing Aid Styles for Children BTE Most common for children All ages and loss levels RITE Smaller than BTE For older children ITE Custom fit Teenagers with stable growth

How to Use Hearing Aids: Step-by-Step Guide

Initial Fitting Process

  1. Schedule an appointment with a pediatric audiologist who will conduct a comprehensive hearing evaluation to determine the type and degree of hearing loss.
  2. The audiologist will take impressions of your child's ears to create custom earmolds (for BTE hearing aids) or assess which style is most appropriate.
  3. Once the hearing aids are ready, attend the fitting appointment where the audiologist will program the devices based on your child's specific hearing loss pattern.
  4. Learn how to insert and remove the hearing aids, change batteries or charge the devices, and perform basic cleaning and maintenance.
  5. Understand the indicator lights, volume controls, and program buttons on your child's specific hearing aid model.

Daily Use Procedure

  1. Check the hearing aid battery each morning using a battery tester. Replace if needed. For rechargeable models, ensure they were charged overnight.
  2. Visually inspect the hearing aids for any damage, cracks, or debris in the microphone or receiver openings.
  3. Turn on the hearing aid by closing the battery door or pressing the power button (you may hear a startup jingle or see an indicator light).
  4. Hold the hearing aid with the earmold or dome portion pointing toward the ear canal. For BTE devices, place the main unit behind the ear first, then gently insert the earmold into the ear canal with a slight twisting motion.
  5. Ensure the earmold is seated properly and comfortably. There should be no gaps that could cause feedback whistling.
  6. Verify the hearing aids are working by speaking to your child or making sounds at different distances.
  7. Have your child wear the hearing aids during all waking hours, removing them only for bathing, swimming, or sleeping.

Removal and Storage

  1. Turn off the hearing aids before removing them to prevent feedback whistling.
  2. Gently remove the earmold from the ear canal, then take the device from behind the ear.
  3. Wipe the hearing aids with a soft, dry cloth to remove any moisture, earwax, or debris.
  4. Open the battery door (for battery-operated models) to allow moisture to escape and preserve battery life.
  5. Place the hearing aids in a protective case or dehumidifier in a safe location away from children, pets, heat, and moisture.
Important Note for Parents: Young children may initially resist wearing hearing aids. Start with short periods during favorite activities like reading books or watching a preferred show. Gradually increase wearing time as your child becomes accustomed to the new sounds. Consistency is crucial for successful adaptation.

Maintenance and Cleaning

Daily Maintenance Routine

Perform these tasks every morning before inserting the hearing aids:

  • Visual Inspection: Check for cracks, exposed wires, or physical damage to the hearing aid case and earmold.
  • Battery Check: Test battery power with a battery tester. Replace weak batteries immediately as they can corrode and damage the device.
  • Debris Removal: Use a soft-bristled brush (provided with the hearing aid) to gently clean the microphone ports, receiver opening, and any vents. Brush in a downward direction so debris falls away from the openings.
  • Earmold Cleaning: For BTE hearing aids, check the earmold and tubing for earwax buildup. Use a wax loop tool to gently remove blockages without pushing them deeper.
  • Surface Cleaning: Wipe the entire surface with a soft, dry cloth. Never use water, alcohol, or chemical cleaners on the electronic components.

Weekly Maintenance Tasks

  • Replace wax guards or filters according to manufacturer instructions, typically when earwax buildup is visible.
  • For BTE hearing aids with detachable earmolds, disconnect the earmold from the tubing, wash it in warm soapy water, rinse thoroughly, and ensure it is completely dry before reattaching (usually overnight drying is recommended).
  • Check all switches and dials to ensure they move smoothly and function properly.
  • Clean the battery contacts with a dry cotton swab to prevent corrosion.

Storage and Protection

Proper Storage Guidelines:
  • Store hearing aids in a clean, dry place at room temperature
  • Use a hearing aid dehumidifier overnight, especially in humid climates
  • Leave battery doors open when not in use to allow moisture to evaporate
  • Keep in a secure case out of reach of children and pets
  • Never leave hearing aids in direct sunlight, near heaters, or in vehicles
  • Remove hearing aids before using hair spray, perfume, or applying lotions
Daily Cleaning Checklist MORNING: Check battery and clean device EVENING: Wipe dry and store properly WEEKLY: Replace wax guards and deep clean NEVER use water on electronics ALWAYS brush debris away from openings STORE in dehumidifier overnight

Precautions and Safety Guidelines

CRITICAL BATTERY SAFETY: Hearing aid batteries are extremely dangerous if swallowed or inserted into body openings. They can cause severe chemical burns, internal damage, and even death within hours. Keep all batteries locked away from children. If you suspect a battery has been swallowed or inserted into the nose or ear, call emergency services immediately and contact the National Battery Ingestion Hotline at 800-498-8666.

Water and Moisture Protection

Although many modern hearing aids have water-resistant ratings (such as IP68), they should never be deliberately exposed to water. Always remove hearing aids before bathing, showering, swimming, or any water activities. Even water-resistant devices can be damaged by prolonged moisture exposure. Sweat during intense physical activity can also harm hearing aids, so consider removing them during vigorous sports.

Physical Damage Prevention

  • Handle hearing aids gently, especially the delicate microphone and receiver components
  • When inserting or removing devices, sit on a soft surface like a bed or couch to prevent damage if dropped
  • Keep hearing aids away from pets, as they are attracted to the scent and may chew or swallow them
  • Check clothing pockets before washing, as hearing aids accidentally left in pockets are often damaged in the laundry
  • Avoid extreme temperatures, direct sunlight, and sources of heat
  • Never attempt to repair broken hearing aids yourself - always contact your audiologist

Hearing Aid Fit and Comfort

Signs of Poor Fit: Watch for redness, skin irritation, or discomfort in or around the ear. Persistent feedback whistling may indicate an ill-fitting earmold. As children grow rapidly, earmolds need frequent replacement. Contact your audiologist if you notice any of these issues or if the earmold seems loose or difficult to insert.

Activity Considerations

Hearing aids can be worn during most daily activities, including outdoor play and organized sports. For contact sports, consider using a headband or special clips to secure the devices. Some families use protective sleeves or wraps designed for active children. Discuss your child's activity level with the audiologist to determine the best protective options.

Troubleshooting Common Issues

Hearing Aid Not Working

  • Check if the battery is dead or inserted incorrectly (positive side up)
  • Ensure the hearing aid is turned on
