Sound Amplifier: Hearing Boost

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.
