Yep. And "boomboxes". Since loudspeaker destruction would be
impossible, a viable approach might involve the shaping of the audio
frequency response such that all frequencies below a few hundred
hz would be attenuated greatly.
I have to say, my attitude of "there are no good viruses" (In this
case a worm or Trojan actually) changes immediately when I
contemplate a "boombox buster"
