Special Report: "Sound of Life"Updated: Friday, August 2 2013, 09:23 PM EDT The story within the story was far more emotional than we could have ever imagined. It began with a simple lesson about sound.We went to W. Buncombe Elementary to do a piece about Dr. Bob's SoundSchool, a Bob Moog Foundation project at Asheville and Buncombe Schools. It's an interactive program about the science of sound.But when we asked Garron Greiner about the worst sound he had ever heard, our special report went in an entirely different direction."The sound of someone screaming," said Garron. "My sister is in the hospital."Suddenly, we discovered the story of a brother-sister bond that could not be ignored. Garron's sister, 5-year-old Jordan, is fighting for her life at Ronald McDonald House in Chapel Hill.Her big brother, who's 8, is the beacon of hope for the entire family with his amazing spark of humor. The spark that instantly caught our attention in class.The lesson about sound that we ended up with was far deeper than we thought it might be. Especially when mother Lisa Grice told us that all she wants right now is the sound of her kids laughing together, and even fighting. The sound of the dog barking, or better yet, all of those household noises at once.The background noise is what the whole family craves most. In the worst of time, they realize such sounds are music to their ears.Special Report: "Sound of Life"
