DeAshcroft writes "Researchers at the Penn State Acoustics Lab have developed life-saving baseballs. As described in the Journal of the Acoustical Society of America, the team put microphones and wireless transmitters into baseballs, which they toss into piles of rubble to find the (noise-making) survivors. The advantage with baseballs is that they apparently don't have to stop work on the pile to listen for survivors. So, remember, if you're ever trapped in a collapsed building, the basball is your friend. The college paper has a story."

they are wireless microphones, theres nothing about the baseball that means anything. The article says they put one of the mics in a baseball and hit it with a bat to test shock resiliency.
