Researchers at MIT's Lincoln Laboratory, a United States Department of Defense research facility, developed laser systems that can "transmit various tones, music and recorded speech at a conversational volume" to specific people without the recipient wearing any special equipment. Basically, the operator points a laser at someone from a distance and that individual hears the transmitted audio even though others in the area don't.
The new approaches are based on the photoacoustic effect, which occurs when a material forms sound waves after absorbing light. In this case, the researchers used water vapor in the air to absorb light and create sound...
One unique aspect of this laser sweeping technique is that the signal can only be heard at a certain distance from the transmitter. This means that a message could be sent to an individual, rather than everyone who crosses the beam of light.

Gives a whole new meaning to the phrase, “My ears are burning, someone must be talking about me.”................

This explains the voices........
This explains the voices........
Oh how about, “The voices in my head kept telling me to kill everyone”.
or not.
;-)
could have a lot of fun with this.
Saw on a tee shirt:
I only do what the voices in my head tell me to do.
And they don’t like you very much..................
Could be useful for battlefield communications.
Would be a neat way to pierce ones ears...................
"All political problems," Karellen had once told Stormgren, "can be solved by the correct application of power.""That sounds a rather cynical remark," Stormgren had replied doubtfully. "It's a little too much like 'Might is Right'. In our own past, the use of power has been notably unsuccessful in solving anything."
"The operative word is correct. You have never possessed real power, or the knowledge necessary to apply it. As in all problems, there are efficient and inefficient approaches. Suppose, for example, that one of your nations, led by some fanatical ruler, tried to revolt against me. The highly inefficient answer to such a threat would be some billions of horsepower in the shape of atomic bombs. If I used enough bombs, the solution would be complete and final. It would also, as I remarked, be inefficient - even if it possessed no other defects."
"And the efficient solution?"
"That requires about as much power as a small radio transmitter-and rather similar skills to operate. For it's the application of the power, not its amount, that matters. How long do you think Hitler's career as dictator of Germany would have lasted, if wherever he went a voice was talking quietly in his ear? Or if a steady musical note, loud enough to drown all other sounds and to prevent sleep, filled his brain night and day? Nothing brutal, you appreciate. Yet, in the final analysis, just as irresistible as a tritium bomb."
Could this be used to prompt people to do things they wouldn’t normally do.
Or could it be used to distract a candidate for public office, by making them deal with voices in their head.
Is the beam of light visible?
Will TOTUS get an upgrade?
Good question. I would think they would use infra-red laser..................
We will all have to dress like Darth Vader or at least Dark Helmet or Jared Goff to proect our ears.
