About this app

Sound Amplifier makes everyday conversations and surrounding sounds more accessible among people who are hard of hearing, using just your Android phone and a pair of headphones. Use Sound Amplifier to filter, augment, and amplify sounds around you and on your device.

Available for devices with Android 8.1 and later. To start using Sound Amplifier, connect your headphones then go to Settings > Accessibility > Sound Amplifier or Settings > Accessibility > Downloaded apps.

• Reduce unwanted noise to recognize speech better.
• Focus on a speaker’s voice in noisy environments with conversation mode. (Available for Pixel 3 and above.)
• Listen to conversations, TV, or lectures. For audio sources that are farther away, Bluetooth headphones are recommended. (Bluetooth headphones might have delayed sound transmission.)
• Personalize your listening experience for surrounding conversation or media playing on your device. You can reduce noise or boost low frequency, high frequency, or quiet sounds. Set your preferences for both ears or separately for each ear.
• Turn Sound Amplifier on and off using the accessibility button, a gesture, or Quick Settings. Learn more about the accessibility button, gesture and Quick Settings:
• Open Sound Amplifier more easily by adding it to your app list. In Sound Amplifier settings, turn on “Show icon in the app list”.

Doesn't "dowhat it says on the tin": refuses to amplify phone media sound. Pressing "Phone media" crashes the app EVERY TIME (yet the mic media works). I was hopeful that the recent update would've cured this, but no. I have a new pair of fancy headphones, but despite all the bells and whistles, the volume is just too low, even at 100%. Many roads point to this app as a solution, but wow - abject failure. I'm on a Pixel 6 Pro running the latest version of Android.

It came with my Pixel 8 and works okay. I tried the recent update but subsequently rolled it back, however. It kept turning off unexpectedly after a couple minutes while using another app or just having the screen locked. It needs an option to configure for either the device mic or headphone mic, though, since I have to have my phone out to use it. Maybe that's just a Bluetooth limitation? Not a bad app as Google apps go, but not great either. It definitely needs more work.

I was really looking forwar to using this, but after installing it, discovered that ot only works with wired headphones. i may have missed that in the fine print, but its 2019, and most smart phones these days are being made without headphone jacks. this would probably be a great app and great technology , if it would keep up with the times, and be compatible with Bluetooth headphones. nobody wants to be tethered to their phones anymore. Thank you for the response google. Review updated

Bluetooth wasn't intended to support very low latency use cases like Sound Amplifier so we had to make the decision to support only wired headphones. Wireless headphones is a high priority for the Sound Amplifier team and we are actively working on potential solutions. Thank you for your feedback.
