Be Careful what you say, and where you say it !

Hi-tech spies can snoop on you with a crisp packet
Researchers have developed an algorithm that can recover audible speech from video filmed from the other side of soundproof glass by analysing the vibrations of a nearby crisp packet
In other experiments, they extracted useful audio signals from videos of aluminum foil, the surface of a glass of water, and even the leaves of a potted plant.

Keep the Curtains Closed, if you are a Spy !
They will not only block direct line of sight video, but also muffle any sound reaching the external window.
However, some Hotel Bedrooms don't need an Algorithm !!

I remember discussions on using a laser beam reflected off a window pane being used to listen in on the conversations inside.
Not new technology but certainly an adaptation on the above Smiley

Pity they don't invent something other than ear plugs that stops you hearing other people's conversations.

What if there isn't a nearby vibrating crisp packet?

There's a few other vibrating items I've heard of Wink
Wonder what messages they could extract from them Grin

I have to think there'd be fundemental problem with this crisp packet thing while someone's actually eating the crisps.  You can barely hear yourself think over that  Grin

I've just invented an acoustic suppressed crisp packet for sale to the military and security services. A snip at £45 each.
Now Zen, but a +Net residue.

Give it a rest - it was entirely on topic and quite an interesting post.
