How loud is a Voxon Photonics VX1 Volumetric Display
Вставка

- People often ask how loud our VX1 is. The VX1 has a resonating screen that moves up and down at 15hz. This movement translates to 30 volumes per second of interactive 3D Volumetric content. The noise that is generated consists mainly of turbulent airflow. As is demonstrated in the video, the air flow noise is attenuated with the protective dome that sits on top of the VX1 ( attached under normal circumstance with 4 hex screws ).
The microphone setting on the YETI mic was set to "omnidirectional" .
Have to say I was really skeptical for a while because all the videos never had audio/ covered with music. I was like "that's awesome, but I bet it sounds like a jet engine". Great to see that's not such an issue as I originally thought. :)
Glad to clear this up. To be honest, some of our first displays were noisy because we had bearings in them. We swapped them for polymer bushings several years ago and the noise levels decreased dramatically. The cooling fan for the projector is now the loudest part.
It looks so cool when you turn it off and the bug just kinda flattens itself. What a great idea for how to create a 3D display.
So THAT's how it works! I was always wondering. So it's basically just a monitor screen which goes up and down in a fast pace and with a synchronized image in the Z-axis. Somehow this is anticlimactic but better than nothing.
i dunno, the fact that the display isnt tearing itself apart with such abrupt motions up and down is pretty impressive to me.
@@guesswho2778pretty sure its a translucent screen of acrylic or something that vibrates with a projector underneath. the actual screen doesnt vibrate
@@HokoraYinphine i hadnt thought of that, that makes so much sense.
@@HokoraYinphineit is. There is another channel that has made a review of it and in some moments of the video the camera is looking straight down into the dome. You can very clearly see a tilted mirror projecting the image onto the screen.
If you read what they said about how this works, they also have said that it is a "high-speed reciprocating screen" that refracts the light as it moves up and down
There’s also another demonstration online where the person shines a laser into the machine, and the light gets deflected into several directions. Looks very weird honestly, but also confirms what you’re saying
There’s also another video on youtube of an engineer that made a volumetric display using the exact technique you’re mentioning. He used an old projector, and used the colorwheel control signal to synchronize everything. It looks almost exactly the same, except a bit noisier (probably bc of synchronization/bandwith/control issues)
0:52 I know you guys' object of this movie is 'loud', but this stopping point shocked me out. omg. it's moving upside down so fast. 3D->2D
my first time exploring this company and product; i didnt even notice that first watch. holy cow this thing is SO cool, i cant wait to see how they could scale up
Wait, it’s just a screen that vibrates up and down really fast? How’s the viewing angle from the bottom??
Great video - certainly not as loud as I would have imagined, and I suspect there are methods to engineer it quieter if prioritised. Understand this is off topic, but curious about how this technology might scale?
I love it. maybe I've been playing too much fallout but holograms should have a cool buzzing humming sound.
Yeah,it makes it cooler.
THIS is a really helpfull and insightfull test. Have always been wondering how loud the display is in a non venue environment.
Thanks! also we should have added, that the 4 positional setting on the mic was set to "omnidirectional"
ahhh that's how it works. unexpected
The noise is fine, the real problem is that the moving display makes this basically impossible to scale up.
igual que una pantalla
Wow, I was sure that you guys would have a vacuum inside of the dome.
My question is why isn't this cool gadget mainstream yet
Wonder if you can improve the durability/reliability by simply pulling a vacuum under the dome. Would remove a lot of unnecessary force on the motors/screen I presume.
It may also reduce the noise.
very damn cool
it's as loud as my fan
Not loud enough for a party. Does it have speakers by any chance?
What do you mean Michael? This is the mechanical noise only that we are measuring. Yes it does have speakers for game audio and also bluetooth.
@@VoxonPhotonics I'm saying it's quiet for an up and down system.
@@manbanasiak yes, that is because we use a resonant amplification mechanism. It's tuned like a guitar string to only vibrate at exactly 15hz.
He’s making a joke
@@VoxonPhotonics missed the joke entirely
wow down at 15 Hertz
If this works the way I think it does... that flat screen would need to be able to refresh at 3600 fps in order to create a 60fps 3d image.
that's what they do afaik, they mention 4000hz.
display is vibrating at 60hz at least.
im fairly certain its 30 fps not 60? the display oscillates at 15hz
Uh, can I not put this in a vacuum chamber, support it magnetically... Eliminate the sound issue. Obviously I'd have to keep it behind the screen but still...
How the h*** does this work?!??!?!
Pay close attention to when he shuts down the machine. You can see that it vibrates a little bit before it fully stops, that’s because the way it works is that it is essentially a 2D screen that goes up and down extremely fast. There’s a projector below it and the software synchronizes the image with the screen height.
@@himalayo It's crazy. It almost looks like a concept, but it's real
@@giorgiolelmi8175 there’s a video here on youtube of am engineer that does something similar to this and he explains the design in detail. He used an old projector and a speaker
A rough price would be good
About 10k, the tech is still in its infancy
A mechanical hologram is just as ridiculous as a mechanical television, and for the same reason. The idea that someone ever though that this would be The Future is truly bizarre. Who is ever going to use this? It is worse in every way than any other system I've seen. I can predict exactly where this is going to end up: in a science museum to entertain children for five minutes, and eventually in a Retro Oddities collection where people will laugh that such a thing ever existed. Even now it looks like some victorian technological folly.
I was intrigued when I didn't know how it worked. Seeing it relies on mechanical motion, with all of the friction, vibration, energy consumption, wear & tear, etc. I came to the same thought as you. This is an oddity, not a viable production technology.
What other systems are better?
Hypervsn.
Basically uses a bunch of overlapping fan blades. If you've ever owned a desk fan, you'll know it's much more reliable than a vibrating table.

And yet people thought the internet was a fad.
Vacuum seal it noob.
Wait you can still see the 3d effect without the glass?
The glass dome just stops someone from touching the spinning led strips
@@sharkylalThis is projector based, so it's actually a projector screen being shielded with the glass dome.
@@reddragonflyxx657thanks for clarifying 😮
