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.

I installed this hoping it would amplify the media sound to my hearing aids because sometimes call volume isn't loud enough. Media playback with my hearing aids is fine, but phone calls sometimes have quieter volume, and I wanted to be able to amplify it. This does not work because you have to have headphones plugged in and hearing aids do not count as headphones. Will change my review if there is an update that fixes this.

This Sound Amplifier DOESN'T amplify or even acknowledge many sounds. Right now I have one earbud in, and I can NOT hear a bird outside my window using the Sound Amplifier App The ear without an earbud can hear the bird loud and clear. This only hears certain sounds. It produces static and feedback when close to other electronics it transfers its internal sounds as sounds in your environment. . It's not good at voices either. I'm sure there are far better free to use apps
