Microphone Amplifier is a way to improve hearing for people with hearing loss.

It lets you use your smartphone as a hearing aid device, allowing you to listen to everyday conversations more easily, such as when you talk with family or friends.

The app detects the audio from the microphone, amplifies it to the desired level, and routes the sound through the earphones or headphones.

The microphone in the app lets you listen to sounds around you, such as when there is a conversation going on in the room, and even when there are loud noises such as when you are driving.
