An unusual example of a sales pitch that is low-key and informative even for people who can't afford the products. Well done.
this is by far the best video I have ever seen on youtube
Max Gaudo too
It's like Bob Ross for sound
Have you seen the talking dog? Cause that shits pretty good!
Also note that our furniture and décor are also part of the treatment process (eg placement of our carpet, wall paintings, curtains, etc.). When we talk inside an empty room we hear a lot of echoes. Once the room is filled with furniture, the echoes are reduced to the minimum because our sofas and paintings absorb some sound reflections. Great and informative video!
This is exactly the type of video I've been searching for! Excellent information and presented in such a way as my ignorant self can easily understand.
I recently turned an unused living room into a home media room but was lost as far as how to "treat" the room for sound. Thank you so much for making this video!
I would love to see a simulation of the room before and after those diffusers and absorbers.
Thank you for this fantastic video. I've been looking for something like this for a while. I'm just starting to treat my living room and this was a great help!
This is simple, clear, logical.... and VERY helpful. Thank you!
By far the best (short) explanation and visualization on the subject I've seen.
Best one I've seen. Problem is - I don't want my living room to look like that ended up in the last part.
Awesome educational videos! Great job in explaining reflections.
That was superb!! Simple and easy to understand
Man, I love your content! Awesome quality, and great in camera personality! I would really love to hear more about pitch perception as it relates to room ambience and absorption :)
This is very helpful! Thanks.
This video is truly what a tutorial should be.., i wish he was teacher when i was in school, i would have had all A's.. Great, Great, Great video..
One of the Best Ideas of SoundProofing is "SoundProof Curtains" That Stops Outside Noise by 80% (25 Db) Tested. Check Here: livesoundproof.com/best-soundproof-curtains/
A great use of visuals..!
Always, great videos.
Great visual examples to express basic concepts

was so impressed by the improvement at 3:20 from only that area coverage of the room
what an EXCELLENT video
I have to commend you on the impeccable explanations. Hell, I'm well versed in acoustics and even I learned a thing or two here!
This is very helpful! Thank you for this!
Great video. It was really helpful.
Terrific visuals. Sound treating any home theatre is so important. Recording studios already have it done usually. Obvious reasons. But in HT's most people ignore it. Before that they ignore or are unable to "sound suppress" the HT room to keep sound in the room. So they can turn up the volume high as they like any time w/o annoying neighbours or waking the baby (iif have one or more...ofc)...
Never seen curved "diffuser" panels. But clearly they work.
This is pretty intelligent. I’ve seen experts get really out of hand… this kept going a little far… but you acknowledged that it may not be necessary to go that far.
Good stuff!
very informative, thank you very much
Thanks! Very good video 👍
Great demo 👍
4:50 most pleasing sound with integrity of timing/phase, loudness/amplitude, tone/harmonics. 5:47 importance of phase coherence
Great video. You do a great job of explaining without getting too bogged down in the minutiae. Much appreciated.
This is amazing💪
Took the voodoo of out room treatment. Much appreciated.
Cool video. Thank you
Fabulous video
This is what i need, thanks a lot
Brilliant thanks
This video deserves 113 million views, not 113 thousand
I have a question about killing very high pitched noises in a wood shop. what would work best? I have a mixture of concrete walls and 1/2 inch drywall.
thank you for this great video !!
Is a skyline diffuser also good for the first reflection ??
or a Perforated Helmholtz Panel Absorber, which is diffuser too with the front.
Thank you! :)
This is why the internet exists. Great video!!
Best acoustics explanation ever seen, thanks for sharing the knowledge
He doesn't do that great of a job.. His idea of Diffusion is not that accurate. Quadratic diffusors are far superior to that of those semi-round reflectors. There's actually a video that Ethan Winer did that demonstrates different types of surfaces. It's about the only video of Ethan's that I feel is worth watching, though.

However, the company that I've found the best acoustic Treatment is Acoustic Fields. They have the best low frequency absorption products. They have hundreds of short videos you should check out. I took some time and looked at practically every low frequency absorption device available and Acoustic Fields ACDA 12 measured the best. Even better than RPG's more expensive Modex units and everything else. The reason is they have deep diaphragmatic cabinets with dual wall and they use the most porous substance (activated carbon) that's densely packed internally. I visited a test lab they had about 6 years ago and I haven't heard low frequency absorption done anywhere near as well as they had..
They actually have low frequency absorption that's effective down to 30hz. Look at the measurements for the absorption coefficients before you buy ANYTHING.
those round diffusors? They aren't really diffusors and in order for them to act more like a diffusor you need a bunch of them. But they are more sound redirection units. the problem with Quadratic is just figuring out the distance, which Prime number to use and having enough distance between the listener and the diffusors. so in really small rooms, you have to have enough distance for Quadratic to work properly. But those actually conform to the requirements of a true diffusor. Those round things don't.
@@Oneness100 If you read what Eric Desart has to say about that you won't be so sure : recording.org/studio-construction-and-acoustics-forum/26648-wasting-my-time-with-homemade-diffusers.html#post195923
Sorry the link doesn't work any more. Here's what Mr Desart wrote : Or you could think of using polys, which are just bend panels.
They are easier to make, giving a smooth response.

@@studiodesquatrechemins8977 Those sties may not have properly done measurements, may not have done enough research, have access to the same materials, etc. etc. and enough testing compared to someone else that has.
There are a lot of different materials, wall construction, testing methods, etc.
@@studiodesquatrechemins8977 That URL doesn't work.
Is it possible for you guys to do a video on a studio solution....this is a home theatre not a studio so im figuring that certain principles would be slightly different.
Not really. Room acoustics are room acoustics no matter if it's for home or studio use. It's physics ;)
Freakin priceless... just, freakin priceless.
good video
genius!
Interesting how you place a diffuser rather than an absorber at the first reflection point. Would you do the same in a recording studio control room?
Yeah... and I watched the whole thing. I saw diffusors, absorbers... all of the usual stuff, but he never actually showed any Acoustic Primer. I was kinda hoping somebody invented sound absorbing paint!
@@poopdrums 😂😂
well that turned into a padded room pretty quick there at the end...
sir i want diy pannels for vocal recording so what pannel i can use is this absorber or diffuser ...i want to use 4 panels on the both 4 sides of a dynamic mic is this ok or not plzzz reply me sir
good!
I'd love to know more about the "phase coherent" part vs the QRD instead of just saying "it's better." Feels kinda phony.
I have a small 4x3m room built from straw bales and rendered in lime plaster. It's totally dead in here. There's no reflection because every surface is uneven and rough. Is this good or bad?
What about rear facing speaker ports. Would the bass produced be slower and be destructive?
I have not so budget, then, Can I put absorbers at every reflection point of sound, in a home studio instead of diffusors.plz reply
What about open layout asymmetrical living rooms? They aren’t the standard 6 wall layout how would you proceed
Im running into this problem now. I have a window and no wall at all at my first reflection point. Use stand alone absorbers/diffusers is what I've been told. It'll look like hell, but should work for the sound.
@@dextermorgan1 the problem is I don’t want it to look goofy. Sucks
@@jimmymcgill5572 Same. I want it to look good. I noticed your comment is a couple of years old. Did you ever install any treatment?
some people say the curve panels are more of deflectors instead of diffusers? can anyone clear my doubt
Acoustical deflectors redirect sound unevenly toward one or more directions, and usually consist of one or more flat surfaces angled to direct sound to the specific direction(s) desired. Constant-radius (cylindrical) curved-surface sound diffusors spread out sound energy reflections evenly over a range of different angles - Acoustic Geometry Curve Diffusors are cylindrical and have a range of about 120 degrees (1/3 of a full circle) of arc, or sound spread, and can be arranged to diffuse sound energy in horizontal through to vertical planes. Curve Diffusors are phase-coherent as well.
Thanks for your question!
But the difussers which dimensions got?
Soooo…. I play bass guitar. Placing my amp in the corner makes it incredibly boomy. Should I place it in the middle of the wall in the clubs we play?
А просто в гости приехать, научиться чему нибудь, можно?
May I have your email id, I have a dolby digital surround speakers, but need to know whether my room setup is accurate for sound or not.
Hmm a mini forrest in my studio...
Anybody else think this was about a new sound absorbing paint?
not all rooms are perfect cubes. What about acoustic in rooms with sloping roofs, walls not parallel and curved.
Only if my physics teacher explained like this.
nobody needs bass treatment right...? -.-
All your claims are crap. Phase coherent diffusors? Ridiculous. And your super flat bass absorbers will do nothing.
Poorly named video and shouldn't be all one video
