One of the great and newer accessibility features on Android is Sound Amplifier, which basically turns your phone into a hearing aid with the help of a pair of headphones and a couple of frequency cut-off faders to isolate the sounds you want to hear.
Now, in its first major update, the applet is becoming available to people who aren’t just using Android 9 Pie devices and is also getting a visual refresh in the process.
Google has announced that Sound Amplifier will now be available to use on all devices with Android 6.0 Marshmallow or later.
It was able to improve the efficiency of the noise reduction process by machine-training its algorithms on thousands of audio samples used in hearing studies and published sources, making the feature accessible to people on older versions.
The company has also taken in feedback from users who wanted more concrete indications of how they were boosting or reducing what they were hearing and has brought real-time audio visualization right in the center of the app.
Also new in this update is the ability to adjust frequencies for each individual ear — because hearing impairments don’t affect people in the same way.
You can grab Sound Amplifier version 2.0 from the Play Store or APK Mirror. If you have a Pixel 3 or 3a series device, make sure to get this update and turn on the feature in the Accessibility settings of your device.
To start using Sound Amplifier, plug in wired headphones (required) then go to Settings > Accessibility > Sound Amplifier.
Sound Amplifier enhances audio from your Android device using headphones to provide a more comfortable and natural listening experience.
Use Sound Amplifier on your Android device to filter, augment, and amplify sound in the real world. Sound Amplifier makes audio clearer and easier to hear.
It works by increasing quiet sounds while not over-boosting loud sounds. With 2 simple sliders, you can quickly customize sound enhancement and noise reduction to minimize distracting background noise.
• Boost quiet and reduce loud sounds around you and on your device.
• Carry on conversations in loud environments.
• Personalize your listening experience by adjusting audio or microphone settings with the simple tuning UI.
• Reduce unwanted or distracting noises.
Once you’ve tuned Sound Amplifier to a setting you like, you can toggle it on and off using the Accessibility Button.
• Phone: Needed to know the phone state to pause Sound Amplifier when there’s an incoming or outgoing call.
• Microphone: Needed for real-time audio processing.
