Hearing Aid App for iPhone – Real‑Time Sound Amplifier
Published: 2025-10-31
A hearing aid app can help you hear conversations more clearly by sending the iPhone microphone to your headphones and applying amplification plus noise reduction. This is a simple, non‑medical way to improve clarity in restaurants, lectures, or at home. It's not a medical device, but it can be a practical hearing companion with AirPods or wired EarPods.
Quick start (≈30 seconds)
- Plug in wired EarPods or connect AirPods.
- Open Heared and choose Hearing Mode.
- Start Amplify → set Gain to a comfortable level.
- Enable Noise Reduction → set to Low or Medium.
- Do a short voice test; fine‑tune Gain and Voice Focus.
Tip: For the lowest latency, use wired EarPods. Bluetooth adds delay.
How it works
- Signal path: iPhone mic → app processing (amplification + filters) → headphones.
- Speech focus: emphasizes speech frequencies (~1–4 kHz) while limiting low‑frequency rumble.
- Limiter: prevents sudden loud spikes.
Settings that matter
- Gain: raise just enough to hear comfortably; avoid over‑boosting.
- Noise Reduction: Low = most natural; Medium = busier rooms; High only if needed.
- Voice Focus/EQ: adds clarity to dialogue; reduce bass if the room booms.
- Latency: wired ≈ best; Bluetooth varies by model.
Troubleshooting
- Echo/lag? Switch to wired EarPods or reduce Bluetooth devices nearby.
- Too noisy? Lower Gain first, then raise Noise Reduction; try Directional mode if available.
- Wind noise outdoors? Cup the mic side lightly or reduce high‑frequency EQ.
- One ear only? Check mono audio setting in iOS Accessibility.
Limits & safety
This is not a medical device and does not diagnose or treat conditions. Keep volumes safe. If you suspect hearing loss, consult a professional.
FAQ
Does it work with AirPods and wired headphones?

Can it replace a hearing aid?
No. It's a general‑purpose assistive listening tool.
Will it filter restaurant noise?
It reduces some background noise and boosts voices.
