I don't hear my heartbeat, lung sounds, or bowel sounds. – iStethoscope Expert Review

I can't hear my heartbeat, lung sounds, or bowel sounds. When I put the iPad on my heart area it makes annoying sounds. And it wasn't firm. And when I put it in my lung area or bowel area the same sound is there. Please fix that!
