Sound Amplifier

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 recognise 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.)
• Personalise 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.dichvucong-bvhttdl.com/accessibility/android/answer/7650693
