Main Question or Discussion Point
What is the possibility of creating a practical portable device which can de-magnitize or otherwise neutralize the magnets in sub-woofers and the like installed in vehicles, but which would not otherwise be damaging to persons or property? The ideal would be a device which, when aimed and actuated at an offending vehicle emitting damaging high dB noise, could eliminate the aural assault. I have asked this question of several faculty members and post-grad students at Florida State University High Magnetic Field lab open houses, haven't found one interested enough to consider. Yes, effective use of such a disabling device, if the source were detected, may result in a civil suit, but it's hard to imagine a jury panel composed of a majority of peers whose ears have not been offended, even damaged, by inconsiderate persons who thoughtlessly or intentionally inflict such harm beyond their reasonable zone of privacy.
