Sound Amplifier

What Sound Amplifier does

Sound Amplifier uses your Android phone’s microphone and on-device processing to make nearby speech easier to hear through connected headphones. It is suited to people who have difficulty following conversations, lectures, or other spoken audio when background noise makes listening harder. It can also amplify sound from media played on the phone.

Useful controls for conversations

The app combines amplification with noise reduction and speech enhancement, helping bring voices forward while reducing some surrounding distractions. On supported Pixel devices, Conversation mode can focus on one speaker in a busy room. You can also adjust sound separately for the left and right ears, which is useful when your hearing is not the same on both sides.

• Amplifies surrounding sound through headphones
• Supports speech-focused listening and background-noise reduction
• Offers separate left- and right-ear adjustments
• Works with on-device media as well as nearby sound
• Can be opened quickly through Android controls and gestures

Things to know before using it

Sound Amplifier requires headphones, and Bluetooth equipment may introduce a delay between a sound and when you hear it. That can matter during live conversations, so wired headphones may be preferable where timing is important. The app is designed as an accessibility aid rather than a replacement for professional hearing equipment. Its audio processing is performed on the device, with no audio data collected or stored according to the supplied app information.
