I used to have a little POC car for driving to work that would backfire loudly whenever I revved it up and let off the gas. Whenever somebody with loud offensive music got next to me, guess what I did? It was pretty loud, too; a couple of blast usually offended the offender. At the next red light, they would never come near me. Heh he he!
Here’s my wish for a secret weapon to destroy the sound systems of auto’s blasting cRap noise posing as music. Just point the device in its direction and the super sonic reverse sine wave traces the sound to its source and destroys the speakers via reverse signal overload. Now if I can only invent such a weapon— it would be put to good use I promise that.
