Wow is this stupid. What did she collect cell phones too?... Surely someone will leak the audio.

Yeah, I really can't wait for that.
There's no good outcome for her for this that I can see....either she said things she doesn't want public, or she used military grade crowd control hardware against reporters (and an innocent neighborhood) for no reason at all.
That's not a good look.

that definition of white noise is way the hell off.

Elaborate please.

Military-grade white noise generators are about #157 on the list of reasons that clip might have been fuzzy.

There were many reports when I posted it, one including a picture of an LRAD mounted on a vehicle in front of the party (that was likely photo shopped), but this is all I can find now.

Blanket white noise generators are why God gave us laser interferometer microphones.

It seems that every news outlet characterizes it as white noise pumped through speakers. The whole LRAD angle apparently come from youtube, with this page being the top result for "LRAD Clinton".

Once you remove the element of it somehow being dangerous, I don't think it's any more unethical than holding a speech behind closed doors. But the use of technology does make it a bit creepy.

Super creepy.
Like I don't have enough mistrust for the government already.

white noise is a random signal with equal power across 20Hz-20kHz (usually). the phenomenon of
'muffling other sounds" with an added sound is called "masking" and has nothing to with white noise specifically. "At high levels, LRADs can cause disorientation, deafness, nausea, and severe discomfort." is true for any sound, not just white noise.

there is also pink noise, brown/red noise, grey noise, plus other less commonly used varieties.
