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.

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

Requirements
• Available for Android 8.1 and later.
• Pair your Android device with headphones.

31 July 2022 - Just installed, and so far so good.... Just testing it on my phone to boost volume while listening to music on a wired headset and it works fine; and you can adjust low and high frequencies as well. Furthermore the feature " adjust ears separately " works fine as well, unlike some users here posted. Going to compare sound quality with other sound booster apps, since the increase of static noise is quite noticeable on this one

A good start but touching my phone causes significant noise. Also, my own voice is delivered with a distracting delay. When these two issues are resolved I believe all 5 stars are due.

It is not an all sound amplifier. Doesn't work with built-in speakers. Viper4Android is better. Trying to enable it without headphones tells me it requires headphones. Five star review requires amplifying the built-in speakers. The name isn't even right. It should be, headphone sound amplifier.
