The Google Sound Amplifier app back in February this year for phones running Android 9 Pie or later and it came pre-installed on Pixel 3 phones. Google has updated the app to support Android devices running Android 6.0 Marshmallow and above. The app enhances audio from your Android device using headphones to provide a more comfortable and natural listening experience. Sound Amplifier uses machine learning that augments sound and filters out background noise for people who have hearing loss.
According to a blog post by Google, the Sound Amplifier now has a new look and feel with an audio visualization feature. To get started, you will need to plug in your headphones and open Sound Amplifier, and thereafter the app will allow you to customize frequencies to augment important sound, like the voices of the people you are with, and the filter out background noise. This will mostly help you in listening to people in noisy environments or amplify the sound coming from your television at personalized frequency levels without bothering others.
The Google Sound Amplifier app has also been redesigned with new UI and several new features, including the option to launch the app directly from your phone’s home screen instead of tapping into Accessibility settings, and with the reorganized the control settings, you can easily tap between boosting your sound or filtering out the background noise.
To start using Sound Amplifier, plug in wired headphones (required) then go to Settings > Accessibility > Sound Amplifier.
Sound Amplifier is available on the Google Play Store and supports phone running Android 6.0 Marshmallow or later.
