Have you seen the videos on the Active Denial System developed by the US military? It's similar to this but uses microwaves focused to essentially overstimulate the outer layer of a person's skin just enough to feel overwhelming pain but not deep enough to burn them. Looks like scary and amazing technology similar to what you're talking about in this video.

When you put the CO2 balloon in front of the speaker you may have missed the "focused" spot of sound. It would have been more instructive if you had moved the balloon around while it was blocking the speaker, both side-to-side and fore-and-aft, to see if there was a strongest (loudest) point. What you showed us could easily have been the equivalent of an unfocused magnifying glass or even the area outside of the focal cone (the "shadow".)

Some of his explanations are a bit inaccurate/misleading though. For example, the refractive difference between mediums isn't actually due to density, although they are related. And the same goes for sound through a medium. Additionally, when he explained how the "sound beam" works, he said it uses pressure waves to propagate, but that's what literally ALL sound is, it's not special to this. And the generator of the waves is absolutely the source of said sound. The source of the waves IS the source of the sound. All waves need a source, and sound is no exception. It doesn't just materialize from the aether.

As for the hypersonic sound laser, I can imagine creating a device that accurately measures how far apart two people are. One person could be 10 miles across a lake from someone else, and shoot the sound laser at the exact same time as a light laser. The person across the lake sees the laser light immediately, and hears the sound 50 seconds later, which tells him the other person is about 10 miles away. That would be cool!

A horn speaker confines the radiation angle of sound, but the dimensions of the horn mouth must be large enough relative to the wavelength to exert pattern control and not just create edge diffraction. Think of a straight pipe having the diameter of the sound source: if you use a small source (such as 1"), most audible frequencies will diffract when they reach the end of the tube, because of the sudden change in radiation resistance (forcing the wave to expand in directions not parallel to the horn wall), and the effective radiation angle will be close to 180 or even 360 degrees in any plane crossing the axis. To constrain the radiation angle to smaller angles while having a mouth that opens to be large enough to control the radiation angle, the horn will need to be exceptionally long, even infinitely long. If you make the sound source tens or hundreds of times larger than the wavelength it is producing, then it will begin to exhibit off-axis self-interference, which becomes more intense as the dimensions of the isophase source (think of a flat piston) are increased, producing coherent summation only in the axis of radiation with minimal spreading, but these sources can become impractically large to transport or mount. (Look at the Meyer Sound SB-3 "sound beam" - it is an array of dome tweeters creating a sound source that is substantially planar, substantially continuous, and substantially isophase.) An array of ultrasonic transducers is able to create narrower beams of sound than a horn can produce, and because even a radiator of practical size becomes large relative to the wavelengths of ultrasound that it is producing, it is able to make use of off-axis self-interference to create a narrow beam at distance. Because ultrasound is being produced, it cannot be heard. It needs to contain modulation content that occurs at audible frequencies in order to be perceived by the ear. So the ultrasound needs to be demodulated somehow, and it does that by interacting with a high impedance surface, causing the ultrasound energy to be reflected in a non-isophase manner and mostly destroyed, but the residual variation in pressure is demodulated as audible sound. In a Class-D amplifier, this is done electrically by passing the modulated ultrasound signal through a reconstruction low-pass filter, but in the physical domain anything providing a reactive low-pass effect can demodulate the ultrasonic carrier, causing the resultant pressure to contain only audible content below the low-pass corner. Once the concept of demodulation is understood, a number of methods for achieving audible transmission become apparent. You can employ frequency modulation (resulting in amplitude modulation of another ultrasonic difference tone between a steady ultrasonic carrier tone and a sliding ultrasonic carrier tone as the carrier), amplitude modulation, or pulse-width modulation. You can use mechanically transmitted pressure waves, or you can use other forms of energy to do this also - radio frequency, microwave frequency, or even light, though the power needed to produce air movement can be great enough to cause injury to a subject, so you would need to be careful. This power, modulated at audible frequencies so the demodulated signal consists only of audible content, can be used to produce audible sound. This phenomenon of energy demodulation is likely what caused American diplomats in Cuba to perceive harsh-sounding audio as they awoke inside their domiciles while their brains were being damaged using a directed energy weapon, causing people in the public to suspect that an "acoustic weapon" was at work; in reality, sound (acoustic pressure waves) would not be able to pass through the walls of their living quarters without being strongly attenuated, but radio frequency energy can pass through walls, and if its modulation contains audible content, then the person or animal subject will experience audio while the rest of the energy is being dissipated in their body in another way (such as frying their brain).

I found this experiment really interesting, I think you should consider that in the case of light, the wave length is way smaller that the lenses, so I recommend to repeat it with a weather balloon and maybe add some distance between the sound generator and the sensor. After all, light experiments mostly use planar and coherent laser like waves. You could use dry ice to obtain the CO2 and use a shotgun mic if you have one. The idea is grate, keep the good work.

Lenses for EM radiation work on transverse waves, but with sound being a longitudinal wave, I'm not so sure it'll work in the same way. I'll keep watching just in case! EDIT: I have a problem with the fact that sound is "focused" using the CO2 balloon. Surely this is due to the higher density allowing more sound to transmit more efficiently? CO2 at the same pressure as air has a lower impedance, so it can transmit longitudinal waves with greater efficacy. If you had a balloon with Helium inside it, it would attenuate the sound considerably. A phased array would be necessary to focus sound, in the same way it's used to focus RF energy into the ionosphere for ionospheric heating (with the HAARP system). EDIT 2: I see! The higher frequencies of the ultrasonic longitudinal soundwaves are created due to their ability to be focused easier using a phased array of ultrasonic speakers, so they may be demodulated by the impedance mismatch of the transducer with the air (or other objects in the way that absorb those ultra-high frequencies, allowing the lower frequency pulse-width modulated signal to be demodulated naturally), and heard by anyone in proximity to the soundwaves.
