If you put on your hearing aids and your voice suddenly sounds like you’re talking into a barrel, you’re not picky—you’re perceptive. That boomy, echoey sensation has a name (the occlusion effect), and there are clear, fixable reasons it happens. The right tweaks can make your voice sound natural again without sacrificing clarity from everyone else.
What’s Actually Happening When Your Voice Sounds Wrong
Two sound paths help you hear your own voice:
- Air-conducted sound leaves your mouth, travels through the air, enters your ear canal.
- Bone-conducted sound vibrates your skull and ear canal walls from the inside when you talk, chew, or walk.
Hearing aids (and the way they plug your ear) change the balance between these paths. When the ear canal is tightly sealed, the vibrations from your own voice get trapped and amplified inside the canal. That creates the classic boomy, hollow, or “head-in-a-barrel” sensation, especially on vowels and when speaking loudly. This is the occlusion effect.
It’s most noticeable when:
- You have normal or near-normal low-frequency hearing but wear a closed dome or power mold.
- Your dome or mold doesn’t sit deep enough, leaving a shallow seal in the soft cartilaginous part of the ear canal.
- Your vent is too small (or blocked with wax), trapping bass energy.
- Your hearing aid is providing more low-frequency amplification than you actually need for your own voice.
Quick Self-Checks You Can Try Today
These checks are safe, simple, and often revealing. If anything seems off, connect with your audiologist for a proper fix.
- Insertion depth check: Gently remove and reinsert your dome or mold, aiming for consistent depth. A too-shallow fit often worsens occlusion.
- Yawning/chewing test: If your voice changes a lot while chewing or moving your jaw, your dome may be moving in the canal—ask about a more stable coupling.
- Vent and wax check: Make sure the dome and any vent holes are clean. A blocked vent can instantly make your voice boomier.
- Try an “open” moment: If your app allows a temporary bass reduction or an “own voice comfort” slider, try it while chatting. Note what feels best and share that with your audiologist.
- Quiet-room trial: Speak aloud in a quiet room at normal volume. If the boominess disappears when you gently pull the aid slightly outward, you’re likely dealing with venting/fit—not your hearing changing.
The Pro Fix: How Audiologists Tame Occlusion
Solving own-voice issues is part science, part craft. Here’s what your appointment might include.
1) Start with verification (probe-mic “real-ear” measures)
Real-ear measurements aren’t just for speech—they can also confirm whether low-frequency amplification is higher than needed. Your audiologist can compare targets to your actual in-ear response and adjust precisely instead of guessing.
2) Venting that breathes (without blowing speech clarity)
Vents act like pressure relief valves for bass energy. Options include:
- Open domes for mild hearing loss, especially if low-frequency hearing is good. They minimize occlusion but let in more environmental noise.
- Vented double domes or custom vented earmolds when you need extra stability or gain. Well-sized vents can balance comfort with clarity.
- Tuned vents (varying size/length) to reduce your own-voice boom while preserving amplification for speech.
Important: if you need stronger amplification, a fully open fit might not work. In that case, other strategies become key.
3) Deeper, tighter… paradoxically better
The ear canal has a soft outer portion and a bony inner portion. Fittings that sit deeper toward the bony part can reduce occlusion because the bony canal vibrates less. That might mean:
- A custom earmold designed for deeper placement.
- A slimmer receiver or different dome style to achieve stable depth.
- Material choice tweaks (e.g., firmer acrylic vs. soft silicone) based on your anatomy and comfort.
Deeper doesn’t mean uncomfortable—when shaped correctly, deeper fits often feel more natural and sound more like “you.”
4) Smarter software: own-voice detection
Modern hearing aids can recognize when you are talking and briefly reduce low-frequency gain or tweak compression just for your voice. If your devices support it, your audiologist can:
- Run an own-voice calibration with you speaking.
- Adjust the strength and speed of own-voice comfort features.
- Create a dedicated “Conversation + Natural Voice” program if you want the comfort without changing your main settings.
5) Low-frequency gain and compression cleanup
Small reductions in low-frequency gain (especially below ~1000 Hz) during your own speech can dramatically reduce boom. So can adjusting how quickly the aid responds (attack/release times) to your voice. These are subtle but powerful tweaks that preserve clarity for other speakers.
Choosing the Right Acoustics for Your Ears and Lifestyle
There’s no one-size-fits-all. Here’s how the pieces fit together.
- Open fittings (open domes, larger vents): Best comfort for own voice and natural environmental sound. Works well for normal-to-mild low-frequency hearing loss. Less isolation in noise.
- Closed/power fittings (double domes, small vents, power molds): Needed for moderate-to-severe loss or to control feedback. Higher occlusion risk—requires careful venting, deeper fit, and software help.
- Receiver-in-canal (RIC) vs. thin-tube BTE: RICs are flexible for custom tips and deep fits; thin-tube BTEs can also be tuned well. Success depends more on the coupling and fitting skill than the form factor.
- Custom earmolds: Best for stability, deeper placement, and precise venting. Great for active lifestyles, small/curvy canals, or when domes won’t stay put.
Special Cases That Change the Game
- Low-frequency hearing is still excellent: Push for more open acoustics or stronger own-voice features; you likely don’t need much bass amplification.
- Significant low-frequency hearing loss: You may need a more closed fit. Focus on deeper placement, clean vents, and own-voice detection.
- Tinnitus: A slightly more open fit can reduce the “head noise” feeling for some. Others prefer sound therapy through the aids. Share your specific tinnitus goals so your clinician can balance settings.
- Jaw movement or fitness enthusiasts: If your dome shifts when you talk, laugh, or run, stability first. Custom molds with a retention feature often solve the “moving target” canal.
Expect an Adaptation Window (and Use It Well)
Your brain has been compensating for hearing changes for years. When amplification corrects the world, your own voice can feel odd at first. Most people adapt within a few weeks when the fit and settings are close to right.
Helpful habits:
- Read out loud for a few minutes daily at a normal volume.
- Track triggers (words, rooms, or moments when your voice feels most wrong) and share them at follow-up.
- Use a “comfort” program for long calls or presentations while you adapt; then try your main program again.
Conversation vs. Music vs. Phone Calls: One Voice, Many Environments
Your own voice interacts differently with different situations:
- Quiet conversation: You may prefer more own-voice comfort. Ask about a tailored quiet program.
- Noisy restaurants: Don’t over-open vents if you frequently battle noise. Consider a directional or remote-mic strategy for these places, then a more open fit elsewhere.
- Music: Music programs often ease compression and bass filtering. Your own voice may feel fuller here—that’s okay if you’re listening more than speaking.
- Phone/video calls: Try streaming level and equalizer tweaks. If your voice is distracting while streaming, your clinician can adjust mixing and sidetone.
When Boomy Isn’t Occlusion
Sometimes a boomy, pressure-like sensation comes from ear health issues rather than hearing aid acoustics—like a sudden earwax plug, a cold/allergy flare changing middle ear pressure, or water trapped after swimming. If your ear feels full, painful, or your hearing changes suddenly, stop and get it checked by a clinician. Your audiologist or an ENT can rule out medical causes quickly.
Your Next Best Steps
- Book a follow-up with your audiologist specifically for own-voice discomfort. Ask for real-ear verification and an own-voice assessment.
- Bring notes about when the boominess is worst, and whether gently pulling the aid out makes it better.
- Be open to trying a different dome, a custom mold, deeper placement, or a tuned vent. Small changes can be night-and-day.
- Give yourself 1–3 weeks to adapt to any major change, with a scheduled check-in to fine-tune.
Bottom line: Your voice should sound like you. With the right mix of venting, depth, and smart programming, it will.

Is the boomy sound harmful or a sign my hearing aids are wrong for me?
Boominess itself isn’t harmful, but it’s a comfort and clarity problem—and a common one. It usually means the fit, venting, or low-frequency settings need fine-tuning for your ear and hearing. Most people get excellent, natural own-voice results after targeted adjustments.
Will switching to open domes fix my own voice?
Open domes often reduce occlusion, especially if your low-frequency hearing is near normal. But if you need more amplification or have feedback risk, fully open fittings may not work everywhere. Your audiologist can try larger vents, deeper placement, own-voice detection, or custom molds to balance comfort and clarity.
How long should I give myself to adapt to a new fit or program?
If the settings are close to right, most people adjust in 1–3 weeks. Your voice should steadily feel more natural, not more annoying. If it doesn’t improve within that window—or it distracts you from conversation—schedule a follow-up for more tuning.
My voice only sounds boomy when I’m on calls or video meetings. Why?
Streaming changes the mix of sound in your ear. You may need adjustments to streaming bass, sidetone (hearing yourself), or the balance between streamed audio and your environment. Your clinician can create a call-specific program or tweak the equalizer to keep your voice natural.
