Were you surprised to learn that some hospitals are now allowing cell phone use? Well don't be shocked if your doctor is chatting on his phone while checking your heart rate with a mp3 player. That's right, according to Canadian researchers, mp3 players can make for better stethoscopes because their plastic encasing can pick up low resonance sounds easier and record them. Early tests have proven that the accuracy is high with the recorded sounds, proving that mp3 players may be making their way into hospitals sooner than we think. via Gearfuse
