Did you know that your earwax type is determined by genetics? A single gene variant (ABCC11) decides whether you produce dry, flaky earwax or wet, sticky earwax. While both types are normal, hearing aid users need to understand the differences because earwax can directly affect device performance, sound quality, and comfort.
Dry vs Wet Earwax: A Quick Comparison
| Feature | Dry, Flaky Earwax | Wet, Sticky Earwax |
|---|---|---|
| Appearance | Light, crumbly, grayish | Brown to dark, soft and sticky |
| Prevalence | More common in Asian populations | More common in Caucasian & African populations |
| Impact on Hearing Aids | Flakes fall into microphones, causing static or distortion | Coats domes & wax traps, leading to frequent blockages |
| Cleaning Needs | Frequent brushing of mics & vents | Frequent wax trap & dome replacement |
How Earwax Type Affects Hearing Aid Users
Both types of cerumen can cause issues if not managed properly:
- Dry Wax: Flakes can clog hearing aid microphones, creating muffled or intermittent sound.
- Wet Wax: Sticky wax often fills domes and wax traps, leading to sudden loss of sound.
Best Practices for Hearing Aid Maintenance
- Brush microphones daily if you produce dry, flaky wax.
- Replace domes and wax traps more often if you have sticky, wet wax.
- Schedule regular ear cleanings with your audiologist to prevent buildup.
- Use a custom ear cleaning plan if you have recurring issues.
When to Seek Professional Earwax Removal
If you experience feedback, weak volume, or a “plugged up” feeling in your ear, professional wax removal may be needed. Avoid cotton swabs, which push wax deeper and may damage your ear canal or hearing aid.
