U.S. intelligence had this tech 20 years ago. I'm pretty sure I read about it on cryptome in the early 2000s.

Since this stuff is based on lasers, don't we have to be in LOS for it to work?

Reminds me of that black mirror episode where you had to pay to mute commercials.

#44The 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.
There is an alternative method to achieve similar results using very high frequency (40khz in the case of the video below) audio as a carrier for audio that is within the human range. It modulates the amplitude of the carrier signal (in the same way that AM radio does). The high frequency audio interacts with surfaces it hits and kind 'self decodes' into human-perceivable audio. It's doable by DIYers with a little electronics knowledge, too!

#45> The ability to send highly targeted audio signals over the air could be used to communicate across noisy rooms or warn individuals of a dangerous situation such as an active shooter. This strikes me as a rather bizarre example to use. What's special about active shooters that would warrant using lasers to beam whispered audio messages directly into someone's ear?
A sad sign of the times, and it looks like the researchers were in the USA. Perhaps the media people thought this angle with garner their invention more attention.

#46Was this used on US diplomats in Havana?
No, that was probably just crickets: https://www.reddit.com/r/worldnews/comments/acs1zv/the_sound...

#47If you want a sound in your year, you get a device for that. If you are a business wanting to notify people who trust you, you can give them devices or blast a speaker. This fills the use case of an actor distributing information to people who do not have enough contact or trust with that actor or who do not want the information (because they would willingly use their own device if they did). Most likely use cases: p…
Those depressing sentiments reflect an unfortunate reality of our time. The world wasn't always bloated with spammy advertising, and I'm hopeful that fad will eventually give way to more human-friendly business models. Yes, any new technology comes with potential for abuse. But I'm still excited that maybe one day this tech could be miniaturized enough (or deployed responsibly) to give me wireless virtual earbuds wit…
A consumer always pays, whether by paying or looking at advertisements.
But the modern world offers nice alternatives now. I can watch movies and episodes without ads (thanks to Netflix), and can listen to all the songs in the world without ads (thanks to Spotify). Because I pay instead of watching ads.
A lot of platforms and products offer the choice between looking at ads or letting you pay.
But of course, everyone wants to have stuff for free without ads, but that's just not how a functional economy works.

Or I'm a spy and I know people will be triggered by on body devices...
Or I just want to cheat on a game show.
