Sound Amplifier

What Sound Amplifier does

Sound Amplifier helps make nearby speech and other sounds easier to hear through an Android phone and connected headphones. It uses the phone’s microphone to pick up surrounding audio, then lets you adjust what you hear. The app is suited to people who have difficulty following conversations, lectures, television audio, or other everyday sounds.

Useful listening controls

The app includes tools for reducing background noise and bringing speech forward. You can adjust sound for each ear separately, which is useful when your left and right ears need different levels or frequency settings. It can also work with media played on the device, not only sounds picked up from the phone’s surroundings.

• Amplifies nearby conversations and ambient sound
• Reduces some background noise to improve speech clarity
• Provides separate controls for the left and right ears
• Supports on-device media as well as microphone input
• Offers a conversation mode on supported Pixel phones

Who it suits

Sound Amplifier is mainly intended for Android users who want extra control over speech and listening volume without carrying a separate assistive listening device. It can be useful in quieter one-to-one conversations as well as noisier places, although results depend on the phone, headphones, surroundings, and the person speaking.
