Sound Amplifier

What Sound Amplifier does

Sound Amplifier uses an Android phone’s microphone to make nearby speech and other sounds easier to hear through connected headphones. It is intended for people who have difficulty following conversations, lectures, or other everyday audio, especially when background noise makes listening harder.

Useful listening controls

The app can reduce some surrounding noise and bring speech forward, giving you more control over what you hear. On supported devices, Conversation mode helps focus listening on a person speaking nearby. You can also adjust sound separately for the left and right ears, which is useful when hearing differs between them.

• Amplifies surrounding sound through headphones.
• Supports speech-focused listening in busier places.
• Offers separate adjustments for each ear.
• Can be reached through Android accessibility controls and Quick Settings on supported devices.

Before you use it

Sound Amplifier is built around headphones rather than the phone speaker, so your listening equipment matters. Bluetooth headphones may introduce a delay, which can be noticeable during live conversations. Compatibility with particular listening modes and shortcuts also depends on the Android device.
