The principle seems simple. It's too bad that 1.9 μm laser is neither easy nor cheap to obtain. Otherwise it could be doable for DIYers.

I imagine you can certainly drive people crazy with this thing. For some one who doesn't know this kind of technology's existence, it's pure magic.

Can't wait till rogue arrays of lasers start beaming advertisements directly into your ear while walking down the street.

Hopefully the ad tech uses the lower-acoustic-clarity method mentioned. It'll be like bus driver announcement white noise. "Wah, wah. And if you wah wah wah, visit wah wah wah dot com today."

Edit: I also wonder how it works if you modulate or otherwise moderate the interface between ear surfaces and ear-surroundings moisture, since that's apparently the resource this method needs in order to work at all. Shopping with headphones on can be a pretty nice experience IMO, and maybe it doubles as a countermeasure.

It would be cool if it were possible to make multicast-like transmissions using this tech.

I can imagine a rock show where the whole band goes straight into the mixer, and instead of speakers PA uses this laser tech to transmit the sound to listeners.

If you are a person who for some reason doesn't receive the transmission, it must feel very bizarre: the only acoustic sounds would be band playing the instruments silently, vocalist singing without any amplification, crowd noises.

It would be a paradise for people making / receiving orders at the bar with the live music going on.

Or imagine a night club where people on the dance floor receive music very loudly, but people outside of it receive it at a conversational level.

This exists with current technology, they're called "silent parties"

Earlier quoted context omitted.

Why not just play it over a speaker like is often done?

Well, now you can directly target people so personalized ads when you're walking down the street. I'm scared it would devolve to pseudo-hallucinations ('did you hear that?').

Or subliminal messages/mind control. I imagine psychiatrist visits would be up due to this annoying voice in peoples heads. lol.

Because then it's obvious where it came from. Much better to spam people anonymously from a distance. People annoying other people with laser pointers is going to become _so_ much more annoying.

True. Antisocial behaviour gets orders of magnitude worse and more prevalent once you can actually make money with it.
