Turn up the world around you. Sound Amplifier uses your phone's microphone to pick up nearby sound and boost it straight to your earphones in real time — so a quiet talker, a TV across the room or a conversation in a noisy café comes through clearer. Tune the sound to your ears with a 3-band equalizer, cut background hiss, and stay protected with a built-in safe-volume limiter. PLEASE NOTE: Sound Amplifier is a general-purpose assistive listening tool for boosting everyday sounds. It is not a medical hearing aid or a medical device. WHAT YOU GET • Live amplification — start listening and nearby sound is amplified to your earphones instantly, with an adjustable gain dial and a live VU meter showing the level. • 3-band equalizer & presets — shape the tone with Bass, Mid and Treble, or tap a preset for Speech, Music, Outdoor or Flat. • Speech boost & noise reduction — lift voices forward and soften steady background hiss and hum so people are easier to follow. • Left / right balance — send more sound to one side if one ear needs it louder than the other. • Safe-volume limiter — caps sudden loud peaks at a level you choose, so amplified sound never jumps to an uncomfortable volume. Start gentle and raise it gradually. WHO IT'S FOR Anyone who wants a little extra help hearing in everyday situations — following a soft-spoken friend, catching dialogue, listening across a room, or cutting through background noise. Always use earphones or headphones for the best result and to avoid feedback whistling. HOW IT WORKS Everything runs on your device using the microphone and your connected earphones. No internet or account is required to listen. AN HONEST NOTE This is a convenience and assistive-listening tool, not a substitute for a medical hearing aid or professional hearing care. If you have concerns about your hearing, please see an audiologist. Begin at a low amplification and keep the volume comfortable. ## Key features - Live audio amplification - 3-band equalizer with presets - Speech boost and noise reduction - Left/right balance control - Safe-volume limiter - Offline functionality ## Frequently asked questions about Sound Amplifier + ### Does Sound Amplifier + have ads?

Thanks for listening with us! ### 1.0.13 — 2026-08-15 New: hearing checks are kept by date, so you can see how your results move over time. Differences smaller than 10 dB are shown as no change, because a check done with a phone and earbuds varies by a few dB on its own. The test now also tells you when it can't produce sound instead of running in silence. Thanks for the reviews and feedback! ### 1.0.12 — 2026-08-11 Two new things and one honest correction. Replay the last 10 seconds. If a sentence goes past before you catch it, turning the volume up only helps with the next one. Now you can hear the one you missed — tap Replay and the last ten seconds play back. Nothing is recorded or saved; it lives in memory for a moment and is gone when you stop. Save your setups. The settings that make speech clear in a busy restaurant are not the ones that suit a quiet television at night. Save what you have as "TV" or "restaurant" and bring the whole thing back with one tap. Previously only balance and the volume limit were stored, so recalling a setup restored two of the six things you had set — everything is kept now. And the correction: the level meter and the LIMIT indicator were reading the microphone before your volume and safety limit were applied. The meter didn't move when you changed the volume, and the LIMIT light stayed off even while the limiter was working hard. Both now show what you are actually hearing. The app also refuses to start when sound would come out of the phone's own speaker, since that feeds straight back into the microphone, and it stops if your earphones come out mid-listen. ### 1.0.9 — 2026-08-05 Alerts now arrive properly on Android instead of landing silently, and the app no longer interrupts you in the middle of what you came to do. ### 1.0.7 — 2026-08-03 Thanks for using our app! This update brings behind-the-scenes performance and stability improvements for a smoother, more reliable experience. Your support means the world to us. ## More apps by heekyung moon - [Blur & Mosaic Privacy](https://appshunter.io/ios/app/blur-and-mosaic-privacy/id6779193648) - [Aurora Northern Lights](https://appshunter.io/ios/app/aurora-northern-lights/id6779193746) - [Golden Hour Sun Tracker](https://appshunter.io/ios/app/golden-hour-sun-tracker/id6779194270) - [GIF Maker & Editor Studio](https://appshunter.io/ios/app/gif-maker-and-editor-studio/id6779194430) - [Slow Shutter Long Exposure](https://appshunter.io/ios/app/slow-shutter-long-exposure/id6780141566) - [Rain Alert Nowcast](https://appshunter.io/ios/app/rain-alert-nowcast/id6780142286) All apps by heekyung moon: https://appshunter.io/developer/6779193748 ## Related topics [amplifier](https://appshunter.io/ios/topics/amplifier) · [amplifier sound](https://appshunter.io/ios/topics/amplifier-sound) · [sound amplifiers](https://appshunter.io/ios/topics/sound-amplifiers) · [sound amplifier live](https://appshunter.io/ios/topics/sound-amplifier-live) · [workiva amplify](https://appshunter.io/ios/topics/workiva-amplify) · [sound amplifier free](https://appshunter.io/ios/topics/sound-amplifier-free) · [google sound amplifier](https://appshunter.io/ios/topics/google-sound-amplifier) · [sound amplifier loud](https://appshunter.io/ios/topics/sound-amplifier-loud) · [hearing amplifier free](https://appshunter.io/ios/topics/hearing-amplifier-free) · [sound boost earphone](https://appshunter.io/ios/topics/sound-boost-earphone) · [amplify](https://appshunter.io/ios/topics/amplify) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
