Though sound is a wave transmitted through the vibration of a medium (particle) and it can be distracted by other forces, it seems our state-of-the-art technology makes the impossible possible.   The performance of a wiretap depends on how fine the sound can be tapped and how far the player can be. But security experts say, "Now, performance is rarely a problem for eavesdroppers," as recent ultra-high-performance eavesdroppers get on and off the media. Eavesdroppers hidden in fountain pen lids and rings, built-in taps built into power outlet...
