Speculative Size: Exploring Perception Through Sound Scaling

[@NineInchFailz]

What an incredibly interesting channel you’re developing. No one is doing this kind of stuff. Please keep doing whatever the hell this is lolol also love seeing Matlab in use, takes me back to my college days

[@pedrova8058]

looooove this nerd topics !!!hahaha 1:45 Besides the dimensions and density, what is missing here is the Young's modulus (elasticity). In homogeneous materials ("isotropic", their mechanical characteristics are the same in all directions) the Young's modulus has no variations. But wood is an "anisotropic" material, that means that the Young's modulus (elasticity) is different depending on the direction of the grain (radial/tangential slab cuts) in relation to the physical plane (if the bar vibrates in one direction in relation to the grain, it has a Young's modulus "A". but if it vibrates in the opposite direction to the grain , the Young's modulus has another value). But basically, with those 3 variables you can calculate the resonance frequency (you get values ​​quite close to those measured experimentally. I got into that whole rabbit hole years ago, studying the construction of marimbas, xylophones, glockenspiels, etc.) 2:43 The result would be even more similar (harmonic content) if the toothpick were supported at the main node ( "0.22 x L", where "L" is the total length of the bar.) Marimba/vibraphone bars, are suspended at these points -and of course, the support point influences the harmonic content (timbre). It's close related to the "Airy" and "Bessel" points, which are studied in structural engineering (sag/beam deformation) and in metrology

Iftah please continue the ultrasonic videos! 🔊♥️ Thank you for your sharing it’s awesome :)

[@GenocidePanda]

beautifully spoken at the end. each fragment is a full representation of the larger macrocosm

[@sonicstate]

Great video and a really interesting topic 👏 Shared on Sonicstate today!

[@DevashishGuptaOfficial]

Love this rabbit hole!

[@TheRealWulfderay]

It's really interesting that there is such a linear correspondence between the physical size and the the playback speed needed to match the frequencies. Though I suppose I shouldn't be surprised because that's really just an expression of the relationship between the size of an object and its resonant frequency. Very cool analysis. Thanks for this!

[@jos9573]

Love how you match the shirt and background color in the animated sections. :)

[@ETTETTE]

This is the best channel ive stumbled upon in a long time

[@TildeSounds]

you're back already! love these videos. I wonder if some of the difference are due to the different amounts of damping being held loosely by hand vs quite tightly in pliers. Is that background music the same wood sound? ^^ lovely

[@iftah_fow]

the point of striking is definitely a very crucial point, and so is the point of mounting of course, with my humble means it was very hard to reproduce the same conditions for both cylinders but i think that its close enough to shed light on the behavior and support the idea of scaling. and yes, the background music is the bigger 60x3cm beech wood sound being played in a sampler

[@TildeSounds]

@@iftah_fow Yes absolutely, the similarities are still really apparent. So much of scale and speed seem related, you also get this in biology where smaller animals have higher heartrates and body temperatures afaik.

[@TildeSounds]

Another thing i just remembered, if you pitch up a tiger roar it sounds exactly like a cat meow ^^

[@garyphillips725]

Cool! Reminds me of a project I've considered for years which is to create a compact performance drum kit that synthesized organic acoustic sounds by the real-time processing of contact mics on carefully curated objects. I imagine a reverb effect going in between the pickup and the pitch shifting effect so as to "lengthen" the sound prior to pitch shifting. I could also see this used with four devices in a box that had MIDI triggered impactors and hands-On tweakability of the struck objects. Yep, the mind is a dangerous thing.😊

[@harriehausenman8623]

Fantastic work! 🤗 I think this is one of these cases, where it is not immediately clear what an application would be, but after a while, it becomes standard in some domains 😉 I could see this being used in games and maybe even some metrology!

[@flippa_da_boss9998]

Can you find the actual relationship between size and sound? This video proves that there is an apparent strong correlation, so it would be cool to hone in on that and find the actual relationship.

[@pedrova8058]

You don't just need the dimensions of the bar and the density, what's missing there is the Young's modulus (elasticity). With those 3 variables you can calculate the resonance frequency (you get values ​​quite close to those measured experimentally. I went through that whole rabbit hole years ago, studying the construction of marimbas, xylophones, vibraphone, glockenspill, etc.)

[@runningwithSaul]

That's what I was wondering but more specifically what rate he would have had to slow down the sound of the smaller object to match the sound of the larger object.

[@HenryBCassidy]

Yess I was so excited to see new video, I rewatched your zooming on sound video several times- really fascinating topic

[@AntonyNorthcutt]

Your videos are so fascinating. I love them!

[@MFKitten]

I would love to hear the sound of the two dropped on the floor, bouncing around, to see if they sound similar, and to see if the bouncing "speed" is similar.

[@harriehausenman8623]

Maybe this justifies a deeper exploration. You could get a big, mostly homogeneous piece of wood and find someone that can machine it to various dimensions 🤔 Also a comparison between metal pieces could be interestings. Same for this: take the exact alloy and let it machine to multiple specific dimensions (maybe PCBWay will jump in and even sponsor a video 😉). Last but not least: A negative test would be most impressive. Taking 3 sticks and one of them is either bigger or in between the 'good' ones and see what the math says.

[@DashGlitch]

oh man, this is fascinating

[@TheRezzua]

Amazing

[@Haggard33draggah]

Love these experiments

[@djayers]

Nice work! Fascinating.

[@corticallarvae]

I aslo have two ultrasonic capsules and this seems like a perfect way to at least temporarily use them …

[@nathanmaoah4906]

Loving these vids!

[@blobmusica]

Phenomenal. Thank you for the vid!

[@leopisaq]

Magniv!

[@melohner5803]

están geniales los videos

[@azeriff]

Amazing!

[@imslicc]

yafe, interesting stuff

[@cellardoreproductions]

Really cool

[@harriehausenman8623]

No Posy here, yet? 😄

[@Grateful.For.Everything]

Yeah that would be cool to get him involved.

[@corticallarvae]

Is this a kyma7+++ project I’m interested in size sonification

[@krowus3833]

lit

[@katiebarber407]

i also have some big wood

[@gjb7966]

+1. always liked your tools and i'm also really enjoying your new channel and content, iftah. this topic and approach remind me of the writings of trevor wishart, but more up to date with current technology. thank you for sharing another rigorous study with us!
