What's the best sound you can hear at the hospital? 

For 19 seconds, several times a day, a soothing lullaby floats through Novant Health Presbyterian Medical Center in Charlotte, North Carolina.
The exact scene plays out dozens of times a day in Novant Health hospitals from the North Carolina coast, to small towns, to Charlotte and the teeming suburbs of Washington, D.C.
A baby has been born. The sweet music signifies and celebrates the beginning of a new life.
