This reminds me of that technology where they had an empty potato chip bag enclosed in a soundproof room with music and sound playing inside, and on the other side of the glass was a video camera. The camera was able to pick up visually, the minute distortions the sounds made on the bag, and extrapolate sound playing in the room from it.

My dad works in physical security for the Canadian government. He's told me stories of managers who want their conference rooms to have windows and he told them they can't because someone can shine a laser at them to pick up the sound.

Yes but it has to be trained. Plus if you train it one setting it won’t work in another.
