After originally launching its Sound Amplifier app earlier this year, Google is now greatly expanding the number of Android users that can access it.

Sound Amplifier is now available to devices running Android 6.0 Marshmallow or higher. That means it's available to way more people than before when it required Android 9.0 Pie or higher.

As its name suggests, Sound Amplifier is an accessibility app that can help you to better hear the things around you. You can customize frequencies with it to augment certain sounds, like the voices of people that you're with, as well as filter out background noise. Just plug in wired headphones and go to Settings > Accessibility > Sound Amplifier or launch the app from your home screen.

Google has also added an audio visualization feature to Sound Amplifier. It'll show you when the app detects a sound, which is meant to help you visualize the changes that you're making to the app. Additionally, you can now easily tap between boosting your sound or filtering out background noise.

There are 466 million people around the world who having hearing loss, so it's nice to see Google greatly expand the number of Android users who have access to Sound Amplifier. It's been a while since Google has revealed the usage of different Android versions, but past reports have shown that it can take some time after a new version is introduced before it's available on a majority of devices, and so making Sound Amplifier available to devices running Marshmallow, Nougat, and Oreo means many more folks can use the app.
