First mentioned at Google I/O 2018, Sound Amplifier works like a hearing aid, boosting the volume of conversations happening around you. In situations with a lot of ambient noise, the app can help you focus on quiet sounds happening near you, like someone’s voice. The level of amplification is adjustable through sliders, and the feature can be enabled through the accessibility menu on your phone.
You will need a device running Android Pie and can only use it with wired headphones. Download Sound Amplifier here from the Play Store.
