[liberationtech] LRAD counter-measures?

Hi Lib-Tech,

I'm a freelance journalist covering the intersection of tech and 
politics. I'm wondering if any lib-techers know of or have experimented 
with ways to disable or reduce the sound from the long-rage acoustic 
devices that the NYPD has been deploying lately. LRADs were also used 
during Occupy.

You know, maybe something like this? http://xkcd.com/368/ ;) (I know it 
doesn't quite work that way...)

Protesters have been talking about the use of LRADs for a while now, but 
the Times just picked up on it in the recent 
#BlackLivesMatter/#ThisStopsToday protests:

If anyone knows of attempts to build such counter-measures or has ideas 
for how one might be built, please feel free to reply to me off-list.

Thanks,
Jay
