Having once taken apart a megaphone similar to the Pyle megaphone you showed at 17:00 the driver is actually in the back of the horn. It's folded twice, with an inner 1st horn hidden underneath the 2nd horn, which is then reflected out to the primary horn. I mounted a 1/4" tube fitting to the end of the megaphone driver I disassembled and turned it into a very effective talkbox.

Great video and channel. Very detailed information and explained very well. I just love learning about random new things, and appreciate how much effort you put into editing to explain such a detailed topic so effectively.

Tech Ingredients, simply one of the best channels on KZread. On this one, I found the physics of wave reinforcement and sweeping frequencies to form continuously variable peaks fascinating. The reverse shield to focus reflected LRAD emissions back to the source was also very cool! Kudos!

This is fascinating. I thought LRAD was this extremely complex system with computers and special materials. This reminds me of an "ultrasonic gun" my father built with a very small horn speaker a little transistor amplifier, and a high-frequency oscillator. He mounted all of it in a plastic pitcher, like you'd use for juice or lemonade, but with a lid. He mounted the horn to the lid, attached the circuitry to plastic rails he glued into it, added what at the time was a large power pack with C-cell batteries, and filled the rest of the empty space in the thing with insulation to damp the sound coming back at the user. The frequency was pretty high -- I could just hear the bottom edge of it, but all he perceived from it was a beam of pain. It worked like gangbusters on stray or feral dogs, some of which ran in small packs in our neighborhood. He'd wave this thing at them and they'd run the other way, howling. About 15-18 years ago, a guy invented a device that would "beam" sound into your head. You'd hear it, but a person right next to you wouldn't. It was designed for focused communication -- the inventor's example was a "shelf talker" device in a supermarket or department store, that would emit a beam of sound that generally would not be heard, but if you intersected it, a short message about that particular product was "spoken" into your head. There was some other talk about it, and I wish I could remember the name of the company the guy started. I was tempted to put some money into stock from that company for my 401K, but I'm not very knowledgeable about stocks, so I dithered on the subject. By the time I'd decided to do it, the company had pretty much vanished, POOF! Turns out they were acquired by a government contractor with military contracts through the DoD under DARPA. A few years later, LRAD popped up on the radar. Seeing that these devices aren't terribly complicated or expensive, I'm seriously considering mounting a couple on my house's roof, to keep unwanted visitors in large groups from getting too close to my house. It would also give me the ability to talk to them without using phones to call or text back and forth. Add some hefty stepper motors and a gear train, and you could aim the thing remotely. Add a goodly-sized LiFePO4 battery pack, a BMS and a small solar panel, and it could easily operate even if power was cut. Per the Non-Aggression Principle, it would of course only be deployed where violence had already been offered, to defend against such violence. I like the idea of being able to back up a request that such persons leave my property with an effective deterrent.

You continue to amaze me with the plethora of knowledge that you have. Not just general knowledge, but detailed technical knowledge. And you have a way of explaining it that makes it easy for us common folk to understand.

Excellent explanation of sound properties and speakers. LRAD started in the same building with the company I was working for in early 2000 in San Diego. We were developing sonar systems for Navy and they were developing speaker systems when they came upon the technology which I believe was developed by either a college professor or a small company. There were other players developing the technology but LRAD obviously did a better job of marketing their technology.

Very technical Very specific Gets into details I love it! Not like other videos that say "I don't know, it just works"

I woke up this morning and found this, I need practice on volts/watts/amps/ohms, keep teaching us.

Great vid, info packed, easy to understand. Can't wait for the ultimate automobile security system... brown noise! "What seems to be the problem officer!?"

Great video! I would like to see an azimuthal power pattern mapping of the horn vs. cone membrane speaker with the same input power to both speakers in your anechoic chamber room if possible. I think this would make a very cool video to thoroughly demonstrate that the radiation efficiency of horn is far better considering the power over the whole pattern as opposed to just one or 2 points.

I'm going to replicate the device you made. Some time back I looked into how LRAD worked but I could not find much about it. Thanks for explaining it. I love your videos.

Then you could make one for each frequency and have a computer calculate the best frequency based on the person position relative to the LRAD. Then move to multiple targets with oscillating frequencies. Might be a good collaboration with Stuff Made Here.

This is a great video! I will say though, anything made by Orion is great gear. Their HCCA subwoofer drivers are legendary. :)

Love your sign, I've been up the cog twice, once on the diesel and again on the steam. Love the show!

This channel is my youtube discovery of 2022. Thank you. Excellent job at explaining things.

31:35 wow! high intensity sound spikes slicing through the air to try and catch you in a standing wave that stabs at your ear drums!?!?

Love your videos! They are oddly relaxing as much as they are entertaining and educational. Keep it up!!

This contains the best explanation of electrical impedance I have ever heard. This bloke is a legend ! Thanks so much.

I have been subscribed for a while now. Most people don't understand a word you say. I feel intelligent due to the fact That I understand what your saying. Thank you for the information and for blowing Kids minds. They think they can throw 2--15"s with a big amp in there truck and bump forever. This is science not BS!! thank you for the work your doing.

I've a feeling you'd dominate a subwoofer competition!

I know where there's cheap property in Hawaii with lava tube access. Just in case you are in the market for a volcano lair.

Inactive lava tube, I hope? If it’s active, LRAD not needed.

I'm impressed with your knowledge and your project quality.

Powerful stuff! One always learns a lot of new things on your channel! I left a couple suggestions for projects on the patreon page! One about a DIY Digital Micromirror Device laser projector (worlds best projector, in addition to the best speakers), and another about a DIY heat recovery ventilation system (a continuation of the climate control videos). It would be very interesting to know if you find these projects feasible/interesting. Many thanks for your great work!

Just thanks for all that nice content! Carry on! And I really love that you folks always tell about the price of stuff. Some youtube channels play with insanely expensive stuff, but get sponsored. So it's really great to know, those things are affordable too.

Sure. As I've said before engineering is the art of compromise and if you don't know the numbers, you don't know anything. Cost matters...

omg this is so interesting, 15 minutes in and this is better than Netflix

Love it! You are one helluva communicator! My kid used to love her science classes -- then she moved on to a teacher who hardly involved the class in labs, and she grew weary of science. Fortunately, I am a bit of a mad scientist myself, and love to run my own experiments, and I think, slowly but surely, she's starting to rediscover the wonder of the physical world we live in!

Good! I think the future of education is not in the institutions that have traditionally been the primary source. With the growth of the network society we'll see more and more connection between students and innovative, appealing and effective teaching.

Amazing explanation of phasing. Thank you.

I just learned some stuff. I mean I always learn some stuff from this channel. Not from scratch coz, I lust the subjects you explain already, but you always expand my knowledge and I will forever be grateful for that. I think it's time I found what this patreon stuff is all about.

When you spoke about Amps, Ohms, and Voltages, I started getting flashbacks to physics class in High School. Then my buddies and I rewiring our car sound systems to make them more powerful. Our teachers both loved and hated us.

This channel is amazing. Thank you so much.

Thanks for the video. I appreciate high information density of your videos.
