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.

Features
• 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: https://support.google.com/accessibility/android/answer/7650693
• Open Sound Amplifier more easily by adding it to your app list. In Sound Amplifier settings, turn on “Show icon in the app list”.

I have but only one gripe about this app that has turned me away from using it. That's the fact that it will automatically turn itself off after leaving/exiting the app. I'm not sure what causes this, for it sometimes occurs right after leaving/exiting the app and sometimes it'll stay on (boosted) but after while it'll turn off. I'm not sure of the cause but if it could be fixed and/or explained I wouldn't mind using this app full time.

It would be extremely nice, if the app wouldn't just stop working because another app suddenly started playing audio. I suppose Android's audio focus is more of a curse than it is a blessing. Also, I don't know why, but the app switches the device mic into some kind of phone call mode as it sounds like I'm in a phone call whenever I turn off the amp and turn it back on. The only way to resolve this I found was to restart the device entirely.

Love the idea, but all of the optional settings are greyed out and Google offers no answers. It would also be nice to be able to use it over a bluetooth speaker in another room, as sort of a baby monitor, instead of only being able to use it with wired headphones. Furthermore, I would love it if it could operate while media is playing, so that I can be more aware of my surroundings on walks while listening to Google podcasts.

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.
