Hooligan chants (and peaceful protest) silenced by delayed echoes?
The New Scientist and others are running a story about a technique that seems to be able to silence a braying racist mob:
Soccer hooligans could be silenced by a new sound system that neutralises chanting with a carefully timed echo.
Stadiums could use the technique to defuse abusive or racist chants, say the Dutch researchers behind it. The echoes trip up efforts to synchronise a chant, neutralising an unwelcome message without drowning out the overall roar of a crowd.
Cool! How long before it’s used on peaceful protesters?

Similar to the effect of a speaker vibrating in the opposite way to the one playing. Theoretically you could stop the music in a nightclub at the bar so you could actually tell the bar man what you want.
Or so my dad tells me :0)

And it distinguishes between racist chants and “come on you Reds!” (or for that matter, “bangin’” techno and a drinks order) in what way?
Although I dare say that “Come on you Reds” is probably a racist chant these days ;-)

Cool. Now work on some technology that does it for forum posts and you’d have saved me about 3 weeks ‘work’ fighting the BNP recently.
