Sound Amplifier

What Sound Amplifier does

Sound Amplifier helps make speech and other nearby audio easier to hear through a connected pair of headphones. It uses the phone’s microphone and on-device audio processing to boost surrounding sound, reduce some background noise, and make voices more distinct. It is suited to people who need extra help following conversations, lectures, television audio, or other everyday listening situations.

Useful listening controls

• Speech enhancement: Adjusts the listening experience to place more focus on spoken voices in noisy surroundings.
• Conversation support: On supported Pixel phones, a dedicated mode helps focus on one nearby speaker.
• Separate ear adjustments: Left and right channels can be tuned independently, which is useful when hearing differs between ears.
• Flexible sources: The app can work with sounds captured around you as well as audio played on the device.

Everyday use

The controls are built around clear labels and sliders rather than a large collection of menus. Shortcuts through Quick Settings and gestures can make the feature easier to reach when you are already in a conversation or listening situation. Bluetooth headphones may introduce audio delay, so wired headphones can be preferable when timing matters.
