Demystifying Hearing Aid Domes: Care and Maintenance

Posted by Kassi Hizr on September 5th, 2023

Hearing aids have transformed the lives of millions by restoring the joy of hearing. Within these advanced devices, the hearing aid dome is a crucial yet often overlooked component. In this article, we will unravel the mysteries surrounding hearing aid domes, exploring their significance in hearing aid functionality and how to properly care for them.

Unveiling the Purpose and Care of Your Hearing Aid Dome

The hearing aid dome is a small, flexible piece situated at the tip of the hearing aid's receiver or speaker. Its primary functions include directing sound into the ear canal and securely positioning the hearing aid within the ear. Domes are available in various materials, sizes, and shapes, tailored to accommodate diverse hearing aid styles and individual ear shapes.

Here are key considerations regarding hearing aid domes:

1. Material Varieties and Types

Hearing aid domes are predominantly crafted from silicone, although alternative hypoallergenic materials are also utilized. Notable dome types include:

• Open Domes: Designed for mild to moderate hearing loss, these domes feature a central opening that allows some natural sound to reach the ear, ensuring comfort during prolonged wear.

• Closed Domes: Ideal for those with severe hearing loss, closed domes provide a complete seal of the ear canal, offering superior sound isolation. However, they may necessitate adaptation due to the occlusion effect, which can cause one's voice to sound hollow or strange while speaking.

• Power Domes: Catering to individuals with profound hearing loss, power domes are larger and more robust, ensuring optimal amplification and retention within the ear.

• Venting Options: Some domes come with vents, facilitating improved airflow and ear comfort. These are especially useful if you experience discomfort or a sensation of blockage while wearing hearing aids.

2. Proper Fitting and Compatibility

Selecting the right hearing aid dome is crucial for comfort and optimal hearing performance. The dome's size, shape, and style should align with your hearing aid model and your specific hearing requirements. Your audiologist or hearing healthcare professional will guide you in choosing the suitable dome during your fitting and adjustment sessions.

3. Maintenance and Replacement

Hearing aid domes are not permanent fixtures and naturally degrade over time due to regular use, moisture exposure, and earwax accumulation. Periodic inspection and replacement of your domes are essential to ensure that your hearing aids continue to function optimally and comfortably. Replacement intervals may vary depending on your usage patterns and individual factors, prompting the need for guidance from your audiologist.

Now that we have a comprehensive understanding of hearing aid domes, let's explore essential care and maintenance practices to prolong their longevity and enhance your hearing aid experience.

Nurturing Your Hearing Aid Dome: Best Practices

Proper care and maintenance of your hearing aid dome are paramount to sustain your hearing aids' peak performance. By adhering to these straightforward guidelines, you can extend the life of your domes and preempt potential issues:

1. Regular Cleaning

Accumulated earwax (cerumen) stands as a common culprit behind hearing aid malfunctions. Preventative measures encompass daily cleaning of your hearing aid domes. Follow these steps:

• Dome Removal: Gently detach the dome from the hearing aid by employing a twisting motion, ensuring no damage occurs to the tubing or the hearing aid itself.

• Dry Cloth Wipe: Employ a soft, lint-free cloth to meticulously eliminate visible earwax or debris from the dome. Steer clear of tissues or paper towels, as they may leave behind unwanted fibers.

• Utilize Wax Picks or Brushes: Specialized tools featured in hearing aid cleaning kits can facilitate dome and component cleaning. If available, use a wax pick or brush to delicately dislodge stubborn earwax from the dome's openings.

• Mild Soap Wash: For silicone domes with water-resistant properties, consider washing them with a mild, hypoallergenic soap and warm water. Ensure thorough rinsing and permit air drying before reattaching them to the hearing aids.

• Inspect for Damage: While cleaning, conduct a visual assessment of the dome for signs of wear or damage, such as cracks, tears, or distortions. Promptly replace the dome if any issues come to light.

2. Replacement When Necessary

As previously mentioned, hearing aid domes possess a finite lifespan and will eventually succumb to wear and tear. The replacement frequency hinges on factors such as usage, earwax production, and the specific dome type employed. Generally, a rule of thumb suggests dome replacement every 1-3 months.

Indications that herald the need for hearing aid dome replacement encompass:

• Evident Wear and Tear: Visual cues like cracks, tears, or distortions in the dome material.

• Diminished Comfort: Discomfort or irritation when wearing the dome may signify its loss of shape or softness.

• Sound Quality Decline: A noticeable drop in hearing performance may arise from a partially blocked or damaged dome.

• Suboptimal Fit: A loose or improperly fitting dome can result in feedback or discomfort.

Consult with your audiologist or hearing healthcare professional for personalized guidance regarding the timing and procedure for replacing your hearing aid domes. Additionally, when it's time to replenish your hearing aid supplies, consult a professional for expert advice on achieving the best fit and performance.

3. Shielding from Moisture

Moisture poses a potential threat to your hearing aids, including the domes. To safeguard your devices, avoid exposing them to excessive moisture from activities like heavy rain, swimming, or direct water contact. While some hearing aids boast water-resistant features, err on the side of caution and remove them when participating in moisture-prone endeavors. Employ a dehumidifier or drying kit to expel accumulated moisture when storing your hearing aids overnight.

4. Gentle Handling

Handle your hearing aids and domes exclusively with clean, dry hands. Prevent accidents such as dropping or mishandling, which may lead to damage. When not in use, store your hearing aids in their protective cases to stave off dust and debris accumulation.

5. Scheduled Check-ups

Routine appointments with your audiologist or hearing healthcare professional constitute a proactive approach to hearing aid maintenance and performance optimization. During these sessions, they can inspect your domes, thoroughly clean the hearing aids, and enact any necessary adjustments to uphold peak performance.

Hearing aid domes, though small, wield substantial influence over the effectiveness and comfort of your hearing aids. By assiduously tending to your domes, you can prolong their lifespan, safeguard the quality of your hearing experience, and preempt issues linked to earwax buildup and wear and tear. When it's time to replace your hearing aid supplies, seek counsel from a professional to ensure an ideal fit and optimum performance.
