A Simplified Guide To Hearing Aid Domes – Usage, Fit & Tips

What Are Hearing Aid Domes?

If you’ve recently started using behind-the-ear (BTE) or receiver-in-canal (RIC) hearing aids, you may have encountered hearing aid domes. But what exactly are they?

Hearing aid domes are small, soft, mushroom-shaped silicone tips that attach to the end of hearing aid tubing or receivers and fit into the ear canal. Their main purpose is to deliver sound directly into the ear while ensuring comfort and secure placement. They come in various shapes and sizes and are commonly used with RIC or BTE hearing aids.

4 Different Types of Hearing Aid Domes That Are Commonly Used

There are several types of hearing aid domes, each designed for specific hearing needs and levels of occlusion (how much they block the ear canal).

1. Open Domes

• Have openings or vents that allow natural sound and air to pass through.
• Ideal for mild to moderate high-frequency hearing loss.
• Preserve natural acoustics and reduce the “plugged ear” feeling.

2. Closed Domes

• Provide more occlusion than open domes.
• Offer better amplification, suitable for moderate hearing loss.
• Help prevent sound leakage but may feel more enclosed.

3. Power Domes (Double Domes)

• Double-layered for maximum seal and minimal sound leakage.
• Designed for moderate to severe hearing loss.
• Great for preventing feedback (whistling sounds).

4. Tulip Domes

• A hybrid between open and closed domes.
• Flexible petals adjust to the ear canal shape.
• Balance comfort and sound retention.

Different Sizes They Come In

Hearing aid domes typically come in various sizes to fit different ear canals:

• Small (S)
• Medium (M)
• Large (L)
  Some brands also offer extra-small (XS) or extra-large (XL) options.

Choosing the right size ensures:
✔ Better sound quality
✔ Secure fit
✔ Improved comfort

When Is It Ideal to Use Hearing Aid Domes?

Hearing aid domes are ideal when:

• You use RIC or BTE hearing aids with thin tubes or speaker wires.
• You have mild to moderate hearing loss (open or tulip domes work best).
• You need a secure fit or stronger amplification (closed or power domes).
• You prefer a non-custom solution (no need for ear impressions).

They are especially helpful for first-time users as they offer a comfortable alternative to custom earmolds.

Pros and Cons of Hearing Aid Domes

Pros:

✅ Comfortable and lightweight
✅ Easily replaceable and affordable
✅ Open domes allow natural sound
✅ Less visible than traditional earmolds
✅ Provide good retention in the ear

Cons:

❌ Can fall out if not sized correctly
❌ May cause feedback if not sealed properly
❌ Not suitable for all types of hearing loss
❌ Require frequent replacement and cleaning
❌ Can get clogged with earwax

How to Clean Hearing Aid Domes?

Keeping domes clean is essential for performance and ear health. Here’s how:

1. Remove the dome gently from the hearing aid.
2. Wipe off debris with a soft cloth or tissue.
3. Use a brush or wax pick for stubborn wax buildup.
4. Avoid water, alcohol, or harsh chemicals.
5. Let them air dry before reattaching.

Pro Tip: Clean domes daily and replace them every 2-4 weeks (or as advised by your audiologist).

How Should They Fit?

A properly fitted dome should:
✔ Sit securely and comfortably without pain.
✔ Create a seal (for closed/power domes) without excessive pressure.
✔ Stay in place during movement or jaw motion.
✔ Not cause feedback (whistling).

How to Choose the Right Size?

• Too small? Risk of sound leakage or falling out.
• Too large? Discomfort or difficulty inserting.
• Best practice: Try different sizes under an audiologist’s guidance.

How to Change Hearing Aid Domes?

Changing domes is simple:

1. Wash your hands before handling.
2. Gently pull off the old dome.
3. Check for wax or dirt and clean if needed.
4. Align the new dome with the speaker tip.
5. Press firmly until secure.

If unsure, ask your hearing care professional for a demonstration.
