People Magazine:

Sam, 21, is on the autism spectrum, and though he’s the epitome of a social butterfly — “People just fall in love with him,” Scott tells PEOPLE — he’s long struggled with an exceptionally loud speaking voice.

“He just never had the ability to modulate it,” says Scott, 59. “For years we’ve been struggling with this, since he started talking… and the voice level is really, really, really loud.”

Enter Apple Watch:

Scott says he was updating his apps one morning when he noticed the Noise app, which measures decibel levels of its users’ surroundings, and turns a corresponding color, flashing yellow when things are loud to the point of risking hearing damage.

And, sharing the app with his son:

“He immediately saw that and started using his own voice to make it work, and then immediately started talking really quietly,” he says. “I was like, you gotta be kidding me. My wife [Cristy] is not gonna believe this. I don’t believe what I’m seeing.”

Great story, yet another example of the life changing power of technology, and the value of Apple Watch.
