This application allows you to enhance the sounds around you, just like a typical hearing aid.
Simply turn on the app and aim the microphone on your device towards the sound source you want to hear (whether it be a TV or other people, for example).
The microphone will catch the sounds and the app will enhance the sound volume for you to enjoy through your earphones.
You can adjust the volume with the slider (your preferred slider settings will be saved for your next use) .
≪Directions≫
1 Attach an earphone jack to your device. Note: Do not use an earphone that also has a microphone as it may interfere with the built-in microphone on your device, resulting in a howling sound.
2  Aim the microphone towards the source of the sounds you wish to hear.
(Normally located at the top for iPod touch  and the bottom of iPhone. Please refer to the user manual of your device.)
3. Using the slider, adjust the volume to a level you find comfortable.
