Is your hearing aid rattling, buzzing, or making static noise? Learn what causes the issue and how to fix it—plus when to get expert repair with free pickup.
Introduction
There’s nothing more frustrating than hearing a constant buzz, crackle, or static sound from your hearing aid—especially when it happens at the worst possible time.
If your hearing aid rattles, buzzes, or produces static noise, it’s not just an annoyance—it’s a sign that something needs attention.
In this guide, we’ll break down why it happens, how to fix it yourself, and when it’s time to call a professional.
Common Signs Something’s Wrong
- High-pitched buzzing only in one ear
- Static noise when touching or moving the hearing aid
- Crackling sounds after changing volume or mode
- Rattling sensation when walking or chewing
- Buzzing near phones or electronics
What’s Causing the Buzzing or Static Noise?
1.
Feedback from Poor Fit
If your hearing aid dome or earmold doesn’t seal well, sound leaks out and re-enters the microphone—causing feedback, buzz, or static.
2.
Wax or Debris on Microphone
Even a thin layer of wax or skin oil on the mic opening can cause muffled or distorted sound. This is a leading cause of static or crackling.
3.
Moisture or Condensation Inside
Humidity, sweat, or sudden temperature changes can introduce moisture inside your hearing aid—leading to crackles, pops, or full-on buzzing.
4.
Interference from Phones or Wi-Fi
Digital hearing aids sometimes pick up interference from nearby electronics, especially if Bluetooth is enabled.
5.
Internal Component Damage
If the rattling persists despite cleaning, it may be a loose internal wire or microphone/receiver issue requiring expert repair.
How to Fix It (Try These First)
1.
Clean the Microphone Port
Use a brush or wax loop to gently clean around the mic openings. Be careful not to press wax deeper.
2.
Replace or Refit the Dome
Try a different size dome for better sealing. A tighter fit often eliminates feedback-related buzzing.
3.
Dry the Hearing Aid Thoroughly
Place the aid in a dehumidifier or drying box overnight—especially if exposed to sweat or humidity.
4.
Switch Off Nearby Electronics
Move away from routers, phones, or tablets. Disable Bluetooth briefly to test for interference.
5.
Reset or Update the Hearing Aid
Use your app to update firmware, or reset the device manually by removing the battery or holding the power button.
