Ideal Room Dimensions: Is the golden ratio really that good? - AcousticsInsider.com

[@motaudio7898]

My room is 21x20 feet 9.5 feet ceilings. I have a Diamond shaped Iso booth in the corner. I put up 6" traps all around with a 4" gap and the difference in low end was absolutely INSANE. Drums sound so balanced and focused.

[@wintersthrall]

Thanks Jesco! Your passion for acoustics has made you a true expert.

[@rootcellarmusicstudiorobku519]

My current control room is a Louden design, (1 X 1.5 X 2.10) I am very happy with it so far. I'm not finished with the room treatment yet but I will be taking measurements in the next few weeks and then hopefully this guy in Germany who has a YT channel called Acoustics Insider will allow me to hire him for a consult. cough cough.

[@Kiartolinho]

Thank you for using understandable measuring units

[@gt4viking789]

It seems that the common denominator here dragging things down is the ceiling height, and sadly something 99.9% of us have to live with! Great video as always 👍🏼 All the best Peter

[@RaytownProductions]

Louden looks pretty awesome 👨‍🔬 Thanks Jesco!

[@EdThorne]

“This only applies to square rooms”… but the measurements represent rectangular rooms. I’m assuming then you mean rooms with 90 degree floor/wall/ceiling angles…?

[@-303-]

I was thinking the same thing. Then again, I can’t speak German at all, and Jesco speaks English with an American accent with only the very slightest trace of his native language.

[@mortenrobinson5421]

He completely lost me when he said that. I don't even know what a square room is? In my mind squares are 2 dimensional and rooms are 3 dimensional.... so did he mean a cubic room? A cubic room does not have golden ratios, in a cubic room width=depth=height. The dimensions for his particular room in his calculator thing is sure as shit neither squared or cubed. It just makes no sense what he's saying.

[@paavoilves5416]

As a non-native English speaker I understand that he probably talks about rectangular rooms. It's easy to accidentally call a rectangle a square, even if you know the difference

To help with desk reflections make the top of your desk a sound absorber. Maybe perforated metal or thick screen and support bars covered with cloth for the top of the desk to support your equipment. Wood frame and rock wool for the core of the desk. Just add some legs and you have a sound absorbent desk. What do you think ?

[@FStoppers]

Been watching a lot of your videos and love the science behind what you are saying…but then a friend I recommended your channel to had an interesting complaint. “Why does his mic audio sound so bad and there is so much reverb in his rooms if he talks about good room treatment?” It hit me and made me pause for a second and thought, well maybe I should just ask you….why so much good information yet such bad sound engineering for KZbin? -Patrick

[@FStoppers]

On another note, maybe you can make a video about this. What is the balance between having some reverb and a “lively” room vs no reverb at all but a perfect space to hear your speakers perfectly transparent? I listened to one of your videos about the anechoic chamber and that made sense but from a podcasting/KZbin/watching movies in a home theater point of view, how much reverb should you have? Is my friend correct in being snarky at your overly “lively” room that makes it hard to hear you on this channel or are these two different purposes and some reverb is good? As a guitarist, I can play straight through and expensive amp like a Soldano and not love the dryness but then it sounds AMAZING with a little ball reverb but is this true with movies and hifi stereo or should you aim for a more dead room for audio that has already been mixed and mastered? -P

[@pulDag]

Really nitpicky I would say. I percieve his voice in very natural way even with headphones. By the looks of his treatment in the room, it looks very minimalistic with very good result. My 2c. Still courious about his view on this topic.

[@FStoppers]

@@pulDag I think his audio has gotten better. This was the video I shared that was in the same room but with much more reverb kzbin.info/www/bejne/gJXMZ52Bgc2ZmNk

That's like taking your Ferrari to a mechanic that specializes in fixing Ferraris and then talking mad shit to him because he drives a Ford Focus. Why would he need a specially treated room and thousand dollars worth of equipment to make a FREE (!!!) educational video?

[@LG-er6ng]

I need to make a portable sound booth around my recliner or to sit on bed, due to disabilities for recording voice overs. I was going to use 2" PVC and 14lb blankets. What do you think?

[@TomislavRupic]

this is mine 280x410x560 and I did use amroc when I was designing it and sounds great :)

[@nicoweich5407]

This Video just made me giggity. Great job man!

[@JamesArthurHurley]

I have to ask. IS there ANY dimensions that will get closest to a “flat” acoustic response? Assume you’re building from scratch. What internal room dimensions would minimize modes or at least put the worst modes physically away from the best mix position for furniture and gear, or put the worst modes beyond the range that would be any concern for mixing?

[@4low395]

thanks for sharing your knowledge on this topic!!

[@hifi2169]

Who is reputable to buy high-quality quadratic diffusers from?

[@gnomik33]

I am really confused. Techinally best is the biggest as because of the physical properties of low end, full cycle is 6m long on 60hz if i am not wrong. A lot of engineers who specialise in rooms, say that the room should be at least 30m2. I am in Louden room, it is not bad but far from perfect. However i can't imagine how to kill lowest freqs in the room of such size

[@jsmith27182]

Could you use the Stern-Brocot tree to do a gradient descent method to find an ideal ratio?

[@amdenis]

Great video. Thanks so much. What is a good source (book, research paper, etc) of specific experimental to practical acoustical validation of Bonello?

[@joost3783]

Hey Jesco what is that Metallgitterplatten style thing u got on ur ceiling? Do you have material above that? Looks interesting would really like to know what you did there in your own room. Maybe I missed it but I would really be very interested in a video what exactly you did to treat your own room and why! thanks as always great content the best on YT for acoustics!

[@jonathanwade8313]

Off topic but this is the latest upload so I figured I'd ask here and hope you have time to reply. I'm trying to redo my listening position based off of the techniques outlined in your bass hunter (and other) guides, and I know that you say that bass traps dont need to be removed, but are ceiling clouds and first reflection panels an issue? I found what I think is my the sweet spot in my room but I'm unsure if the panels are going to be altering that in any way and I'd like to get it figured out for sure before I move my desk back into the room. Thanks!

[@tedanderson5528]

Best sound I ever heard was in a 10x10 concrete room with a $2000 system.

[@SchultiTube]

Hey Jesco, for your basshunter technique: Is it a good idea to listen to the selected music with a lowpass filter on it, lets say on 300hz to fucos just on the lows? Thanks!

[@chrisbistrishki]

hm, interesting idea at first but I actually wouldn’t really recommend it since a lot of “low end” material like kicks, basslines, low synths etc. also have overtones in their overall sound design and timbre. You’d rarely hear a bass or a synth which are pure sine-waves. So with that in mind I don’t think it’s a good idea to “castrate” a big part of the timbre of those sounds sitting higher up in the spectrum, because that’s often what helps our ears establish the relationship between them in a mix. For example how well a bass and a kick work together. The fundamental notes wouldn’t be enough in my opinion. In my experience those notes sitting higher up than what we consider to be “bass” can play a huge role in determining what sits lower or higher, how is the attack and release of the transient shapes the balance of the bass impulse (which could be really easily messed up depending on the type of filter you use, btw), etc. The best way is to just learn to listen really carefully and try to pick those things apart. Of course, the solution to that is (whether we like it or not) loads and loads of practice. :)

[@DerekPetersonLives]

well apparently my room is even more trash than I thought O_O hard to say for certain though as it does have an open L shape on the back left of the space But just look at the damage that 26ft x 10.5ft x 7.75ft does to the bolt area chart O_O

Family Guy? Good man

[@mortenrobinson5421]

2:30 dude, this doesn't really make any sense.. You were talking about a golden ratio room, and then all of a sudden you say that it only works for a square room? A square room is not a golden ratio room, where did the square room enter the picture? We're talking about room dimensions here and a square room does not have golden ratios. I don't even know what a square room is? In my mind squares are 2 dimensional and rooms are 3 dimensional.... did you mean cube room?

[@murraywebster1228]

I think you mean rectangular instead of square…..

[@rootcellarmusicstudiorobku519]

Shoe box is my favorite term for this. Abbey Road studio 2 is my favorite shoe box. :)

[@mortenrobinson5421]

I think he means a box-shaped room with right angles, but I can't be sure cause it makes no sense what he is saying. Rooms are 3 dimensional objects and squares are 2 dimensional, hence a room can neither be square or rectangular.

[@stevescharrer5193]

The word square rooms means 4 equal length walls. Someone explain the term rectangle to him. I have a hard time taking advice who can’t get basic terminology correct.

[@YSLRD]

Lol. A square is a rectangle but a rectangle isn't necessarily a square. In any case, he's talking about 90°corners.

[@pecacartun]

Hey Jesco, you should use approximately same room volume when comparing different ratios. That would give the more fair and realistic results. Or, for an example, not to use Height as a reference, but width. So to change the numbers around foxed width. I now it's a lot more work, but it's also more fair to those poor small room's. :D Cheers

[@shaftahoy]

It would be interesting to experiment with, but I assume he's kept the height at 2.5m because that's around the height of most ceilings in most homes!

[@lahattec]

When you say "square" room, do you mean rectangular? Your dimensions aren't a square.

[@thematsc]

Super nice and interesting video! Thanks!!! Always use metric (if you ask me). Imperial should be .....well lets politely say ...never used :-)

[@murraywebster1228]

[@shaftahoy]

No, 'square' in this context means all angles at 90°.

[@murraywebster1228]

@@shaftahoy it was a long time ago when I was at school but a square in any context means equilateral sides….that’s what makes it a square as opposed to a rectangle……or is that too complicated to teach these days…..

[@shaftahoy]

@@murraywebster1228 The word has many meanings and usages - what you describe is one of them. Another is "having right angles". When two lines or planes have an angle of 90° between them, they are said to be square with one another. Have a nice evening.

[@-303-]

Using “square” in this way is very unusual, and in 50+ years I have never heard of a “square room” meaning “a room with wall that are all square with respect to adjacent walls”. That doesn’t mean it’s wrong. It does mean that using the word “rectangular” would get the point across more easily to more people, and that’s the whole point of communication.
