Digital Hearing Amplifier
A digital hearing amplifier processes your microphone audio to work at all, which is exactly why it's worth checking what happens to that audio before you install anything. Here's a plain-language privacy label, not buried in a settings menu.
- Not a hearing aid
- Nothing recorded
- No account needed
- iPhone & Android

What actually happens to your microphone audio
This is a plain-language summary, not a substitute for the app's full privacy policy, linked from its App Store and Google Play listings.
How it works
Three steps, no account required
Connect headphones
Wired or Bluetooth, whatever's already around — nothing new to buy first.
Aim the phone
Toward whoever's talking, or toward a speaker — amplification follows the direction it's pointed.
Adjust the level
Plus and minus controls appear the moment amplification starts, with the EQ one tap away.
What it does
Built around what actually helps
Voice separation
Speech gets pulled forward relative to background noise, instead of the whole recording getting louder together.
Three-band EQ
Bass, voice, and treble adjust independently, since a fixed profile suits nobody exactly.
Loud-sound cap
Sudden spikes get capped automatically rather than blasting through at full amplified volume.
No processing lag
Runs live on the device, with no noticeable delay between speech and hearing it amplified.
Offline by default
No connection required to amplify — the internet only matters for the initial download.
Shared subscription
Up to 4 devices on one Premium plan via QR code.
Getting the setting right
How much boost actually belongs in the room you're in
The right amount changes with how loud the space already is — the level that feels perfect at the dinner table can feel harsh on a train platform, and "too quiet" doesn't always mean the master level is too low. Sometimes it means the wrong band is doing the work.
- Voices sound louder but no clearer — usually the overall gain moved up while the Voice band stayed flat.
- Background hiss or hum gets amplified along with speech — try lowering Bass before touching the master level.
- Sudden sounds feel sharp or slightly painful — the loud-sound cap is doing its job, but the base gain is probably set too high to begin with.
- Everything sounds thin and tinny rather than clear — Bass is sitting too low relative to Voice and Treble.
| EQ band | Raise it when | What it changes |
|---|---|---|
| Voice | Speech disappears under background noise | Pulls speech forward without also boosting hum |
| Treble | Consonants sound mumbled or muffled | Sharpens "s," "f," and "th" sounds |
| Bass | Overall sound feels thin or tinny | Fills out low tones without drowning out speech |
| Overall gain | Everything sounds too quiet, not unclear | Raises volume across every band at once |
Adjust one band at a time. Moving Voice, Bass, and Treble together makes it hard to tell which change actually helped — nudge a single slider, listen for a few seconds, then move to the next one.
Loudness doesn't rise in a straight line with the slider — each roughly 10 dB step doubles how loud a sound feels, which is why a small move near the top of the range changes more than the same-sized move near the bottom.
A quick way to find your baseline
- Start in a quiet room with the overall gain low and Voice Focus off, then raise it just until speech feels natural, not simply louder.
- Walk into a noisier space and raise the Voice band before touching the master level — it's usually enough on its own.
- Save that combination as your normal starting point, then adjust only Bass or Treble for a specific room from there.
Common searches
What people usually mean by "digital hearing amplifier"
"Is a hearing amplifier app safe to use"Usually means checking privacy and data handling, not just whether the amplification itself is safe — the label above covers exactly that.
"Does a hearing amplifier app record you"This one doesn't — audio passes through in real time and is never saved or transmitted.
"Free digital hearing amplifier"The free tier here covers 3 real sessions a day with no account required.
"Hearing amplifier for TV"Pointing the phone at the screen lifts dialogue above music and effects better than another notch of TV volume alone.

Questions about digital hearing amplifiers and privacy
Does the app store or send my audio anywhere?
No. Audio is processed live on the device for amplification and is never recorded, saved, or transmitted to a server.
Do I need an account or email to use it?
No. There's no sign-up form — the app is usable immediately after opening it.
Is this a hearing aid?
No. It's a general sound amplifier, not a regulated medical device, and not fitted to a diagnosed hearing loss.
Why does it need headphones instead of the speaker?
Playing amplified sound out of the same phone that's recording it creates feedback. Headphones avoid that loop entirely.
Is the free version actually usable?
Yes — three real listening sessions of 15 seconds each, every day, with no account required.
Does it need an internet connection?
No. Amplification runs entirely on the phone. A connection only matters for the download or an optional subscription.
Can I share one subscription with family?
Yes — a Premium subscription covers up to 4 devices through a QR code.
Does it work on both iPhone and Android?
Yes, with the same core features on both the App Store and Google Play versions.
