Google Sound Amplifier

FreeDifficulty: Easy

Last checked: 5 November 2026

What Is It, In Plain Words?

Google Sound Amplifier is a free Android app that makes conversations and other sounds easier to hear through wired or Bluetooth headphones. It can reduce background noise, boost quiet speech and let you tune low or high frequencies for each ear.

It is made by Google for people who are hard of hearing, or who just want a clearer listen in a noisy room. It is not a medical hearing aid. Conversation mode, which focuses on the person in front of the camera, is available on Pixel 3 and later. On many phones you can also open it from Settings, then Accessibility.

What You Can Use It For

  • A busy café or family meal. Put on headphones, open Sound Amplifier, choose Phone mic, turn up noise reduction and boost quiet sounds so speech stands out.
  • TV or a lecture without turning the volume up. Place the phone near the speaker and listen on Bluetooth headphones, so others keep a comfortable volume.
  • Tuning each ear. Tap Adjust ears separately if one ear needs a different boost than the other.

Getting Started Step By Step

On A Phone Or Tablet

  1. Open the App Store (iPhone and iPad) or Google Play (Android).
  2. Search for Sound Amplifier and check it's made by Google LLC. Copycat apps exist.
  3. Tap Get or Install, then open it.
  4. Allow the microphone when it asks. Google's help page says the app processes audio for amplification and filtering, and that no audio data is collected or stored for that purpose.

From Accessibility Settings

  1. Open your phone's Settings app.
  2. Tap Accessibility, then Sound Amplifier, then Open Sound Amplifier. On Pixel phones it may already be installed.
  3. Connect wired or wireless headphones.
  4. Tap Phone mic, then drag the Noise reduction and Boost quiet sounds sliders until speech is clearer.
  5. On a Pixel 3 or later, try Conversation mode and point the camera at the person speaking.

Things To Try Typing

Things to try in the app.

  1. Open Sound Amplifier and put the phone on the table during a family meal
  2. Turn Noise reduction above 90% in Conversation mode on a Pixel
  3. Boost high frequencies if bird song or soft voices are hard to hear
  4. Use Adjust ears separately if one ear needs more boost
  5. Place the phone by the TV and listen on Bluetooth headphones

What It Costs

It's free. There's no paid version to buy. There is no paid plan.

If anyone asks you to pay to use it, or to "unlock" it, that's a scam.

Checked 5 November 2026 on Google Play (Sound Amplifier by Google LLC) and Google's Android Accessibility help page. Needs Android 8.1 or later and headphones. Conversation mode needs a Pixel 3 or later.

Privacy And Safety

  • What it keeps. Google's help page for Sound Amplifier says microphone audio is processed so the app can amplify and filter it, and that no data is collected or stored for that. The Play Store data-safety section still lists some data types the app may collect; treat that as Google's general declaration for the listing.
  • Tell people when you are amplifying a conversation, the same way you would with a hearing aid.
  • This is not a substitute for an audiologist. If your hearing changes suddenly, or you struggle a lot, see a doctor or hearing specialist.
  • Never type passwords, PINs, bank or card numbers, your National Insurance number (UK) or Social Security number (USA).

Good Points And Watch-Outs

Good Points

  • Free, with no subscription.
  • Simple sliders for noise and quiet speech.
  • Works with headphones you may already own. Conversation mode on Pixel phones can focus on one speaker.

Watch-Outs

  • Android only. There is no iPhone version.
  • Bluetooth headphones can add a slight delay; Google suggests wired headphones for clearer sound.
  • Conversation mode is limited to Pixel 3 and later.
  • It is an accessibility helper, not a certified medical hearing aid.
