I had the chance to spend a day at the Laboratory of Mechanics and Acoustics of Marseille, in France, to visit their anechoic rooms and meet the researchers who work there. I invite you to watch the video of the interview that was made on this occasion (English subtitles available): kzfaq.info/get/bejne/e9qPZK1ktMXUlmw.html

This channel is literally giving us very easy explanation such a huge concepts. Hats off to you Science clic English.

9:35 "this very ambitious project that will RESONATE on an international scale" I hope for the project creators that it doesn't! 😂😂😂

Your narrator has very impressive pronunciation in English, French *and* German, and can switch between the languages on a whim, wow!

It's pretty impressive how well we can model reality with the "masses on springs" approach.

Clicked on this faster than the speed of sound.

I was walking alone in Death Valley one day, and something seemed wrong. I stopped and listened, and I realized that because there was no wind that day, there was literally no sound. It was an eerie experience.

This channel is super underrated. Your work is fenomenal and should reach much more people. The way I see it, channels like this has a pottential to stimulate the develpment of many young minds, that will someday increase humanity's scientific capacity towards finding the explanation - or the equation - of everything.

Ngl, that change of accent at the very end from perfect English to perfect French was the most surprising thing in the whole video :D Which was btw great, as always :D

Your channel has the best videos on science I've seen. Thank you for the great work. Great attention to detail too, like playing the notes in tune with the background music at 8:05.

First time I stepped into an anechoic room I nearly fell over. Shows how much we rely on sound to maintain balance.

Wow this video was immensely detailed and filled with subtleties!

Bravo, a genuine human voice. Thank you

These videos are so satisfying to watch!

as always: superb video. It's the science off course, but on top of that: excellent infographics and perfect voice-over. Thank you so much for these pieces of art!

Incredible techonolgy, i think acooustics and harmonics are way more important than we invest into.

Welcome back, it's been a while! An interesting topic as always.

this channel. issa blessing!🙏🏽

This channel is an absolute masterpiece.

Thank you for making this. I always love it when you make a video.

Excellent job explaining that interesting topic. Thank you sir

Such an interesting topic that I knew absolutely nothing about before this video!

I got to visit the anechoic chamber at my university. Super neat experience. Great video as always.

I almost fell off my chair at the abrupt switch between English and French accents! Manifique!

Like always one of the best science youtube channels.

ScienceClic is one of the few channels that are worth the bell.

这个视频做的太棒了！我反复看了好几遍。把隔音和吸音以非常生动和通俗易懂的方式讲出来，让我受益匪浅！对于做自己家庭影院的隔音和吸音来说，认识原理能更有目的的行动！十分感谢ScienceClic English频道！

Great work.

Such a beautiful visualisation of the sound!

Simply stunning

The split-second I hear that super awesome learning music I hit that thumbs up on immediately

I really like his voice and the way he explains it.

As a bassist, I wholeheartedly support research into sound properties and hope that it enhances how we hear my instrument both on recordings and in live performances.

Amazing! Thank you 🙏🏻

Love your awesome vids!

Great work Alessandro! These animations will certainly provide many with invaluable intuition. Have you heard of "Huygen's principle of secondary wavelets"? It provides a great explanation as to how these waves propagate in 3D space, including around objects. I'd love to see your take on the topic 🚀

Yay another great video I can watch!

Wow, I had this question for a while now. Thanks, great video. I feel like you are too underrated. But keep up the good work!

Anechoic chambers are also used in many Telecommunications projects, ie. measuring antenna’s characteristics and other measures…

Your videos always remind me that you can understand and even invent many things by only using pure imagination. That way of think is so cool. This explains why i love physics though.

Love this channel

great video as always. can you do a series on the Standard Model, that would be very cool

I have two questions, let’s say we wanted to measure a particularly faint sound source within this room: does earth’s gravity affects the air molecules in which it propagates in such a way that we could consider the sound itself distorted? Regarding the next question I was just wondering how they manage the noise from the lights, considering there were many in the videos you showed.

Not only for sound waves, anechoic chambers also using for antenna measurement which for suppresing the electromagnetic reflection

I've come as fast as the notification popped😂this channel is addictive

Amazing video

I am now studying high school meanwhile iam interested in quantum physics I am clearly understood concepts by your videos pls give some more videos

Excellent!!!

Harmonic resonance can move mountains. Frequencies are fascinating, as 'Everything' has it. Cheers.

Very interesting!

You’re a Smart guy 👏

Bravo!

Thank you.👍

perfect!

this guy went from like 50k to 250k subs in a couple of months, nuts

Marvelous

This was super interesting!

The disturbance in the atmosphere that creates waves in the air is we call sound but it’s a phonon. (A wave of disturbed air called a sound wave is a phonon)

jadore tes videos! continuer upload eux!

not sure how I was subscribed to this but I'm thankful. Did this channel go by a different name before?

4 dimensional space-time seems to be fluid. Mass & Energy are 2 sides of the same coin. It almost seems like the more mass something has, the more energy is available to curve space-time. What if space-time is like water, in that if you add energy to it, it changes? If you compress a spring, its mass increases. Because you put energy into the spring as you compress it. I think this might be important when thinking about Gravity, too. Energy into a spring increases its mass. Increase in mass, increases curvature of space-time around the mass. By compressing a spring, you affect the curvature of space-time around the spring. Because Mass & Energy are 2 sides of the same coin. Another example is: If you have 2 identical cups of coffee (atom for atom, exactly identical) ...The cup with warmer coffee will have a greater Mass. Because heat stems from kinetic energy of vibrating atoms. Energy & Mass are 2 sides of the same coin. So your Microwave oven is essentially just a "Mass Increaser". Because it puts thermal energy into your food, & the Mass of your hot food has increased. -But where does a Microwave oven get energy to come on & work?... From electricity used to do work via closed electrical circuits. -Well where do that electrical energy comes from?... It comes from electric (& magnetic) fields. -Where are these fields?... They are part of an aggregate of fields that permeate the whole of space-time. The energy that flows through a closed electrical circuit is essentially leached from space-time & then used to do work. & then restored back to space-time. Nick Lucid from Science Asylum explains this beautifully. -This shows that Energy, Mass, space-time & gravity all work together. & since there _is_ a relationship between Gravity & Mass, I think its worth asking where Energy comes into play with gravity. If the energy density of a unit of space-time increases, is the curvature of that unit of space-time affected? My guess is yes. & I bet Blackholes prove it to be true. What if a Singularity is just that?... A total saturation of energy density per a planck unit of space-time?... #ThinkAboutIt

As a student of physics, I found a catch in the video Sound travels faster in cold air and slower in warm air as air get contracted in low temperatures eg. In winters, train's whistles are heard clearly from long distances as compared to that in summer

Best videos

Au clair de la lune, mon ami pierrot :-) love it

So good

Are you going to do Quantum chromodynaics? Great video as always!

nice

Welcome back to ScienceClic

Could antisound in principle remove the need for the cumbersome and costly wall decoration, wall thickness and insulation? Very interesting video! Thnx

finally a perfect room for us introverts

This is totally RAD!!!

COOL... I use my closet to make an Anechoic room :D

Those mics would need to be placed in the centre of the room as well as around the walls, or they won’t be able to cancel the sound until it’s too late, surely? Noise cancelling headphones are so effective because they’re right next to your ear, with no (perceptible) distance allowed for the sound to travel in either direct. Your French is very elegant btw.

Everybody share this video and channel ❤️

I wish you had gone into more detail about why longer wavelength soundwaves are not blocked by the foam wedges. It doesn't seem clear to me

Anh hát bằng cả trái tim bảo sao mà cứ ngọt lịm như vậy. Bài nào cũng cảm xúc luôn

I am 13 and have a solid understanding of quantum physics including the Heisenberg uncertainty principle as well as quantum fluctuations and quantum electrodynamics. I do, however, have a feigned understanding of quantum field theory as well as symmetries in the universe. Can give me a watered down explanation

Is there any way to make rooms ventilated ? Or how it's done if we wants to stay hours ?

When the two sound wave cancles in the room ,, where does the energy go???

I wanna sleep in a room like that so bad

as sound is described to be a spherical wave, the waves sound also propagate behind the speaker. is this right? see time 5:37 however, the speaker should also have directional properties..

Absolute silence would kill my ears and my mental being lol Just thinking about silence makes my tinnitus scream hard!

👏👏👏👏

I love it! But as a guitarist, I can't imagine the world without reverb. 😂

I got misophonie, this room is my dream... Pure... Silence...

I'm not quite get it. How the low frequency sound can't be trapped by wall wedges?

Early gang!

الله اكبر الحمد لله لاحول ولا قوة الا بالله اللهم صل و سلم و بارك على سيدنا و نبينا محمد

why is it that ANC only cancels low frequencies then?

❤️🙏🏽😀

imagine going in one of these rooms with tinnitus

hey genius!!! please upload a series on mathematics of QFT just like the one of relativity .. it is the most needed thing right now

So, if you stood behind the speaker in the anechoic room, you shouldn't hear it right?

I need active noise canceling system for my bedroom :)

why aren't the walls antiparallel?

His french at the end😂

This video is really depressing for someone with severe tinnitus :(

Please please put turkish translation

A hyperbolic surface room could encompass all frequencies
