Before any of you guys deep heavily into buying all this I highly recommend visiting producer/engineer Eric Valentines RUclips channel. He goes HEAVILY in depth about room frequency cancelation and absorption using numerous microphone frequency tests, products and dimensional shapes, whether it’s panels or tube traps for a specific room
I watched Valentines video and it is interesting. You can get good results with just velocity traps as well, but it is not as efficient in the low end. He had to use a lot of tube traps to achieve similar results that he could have used with a Newell design. Control rooms are very specific in Newell design and need to be followed to a T to get his results.
Eric Valentine has taught me to be a doubting Thomas when it comes to theory in this space. It would be amazing for you to build and @@soundproofyourstudio
If you are in germany, gerstäcker sells picture frames 50x100, which fit ideally to basotect 100x50 plates, you could fill the frame with active coal, and put a hole plate behind it. (They easylie cut it at any hardware store.) They also sell rubber mats which are like 7 mm thick (to insulate washing maschines...) so if you take such a mat, and put it on the back side of the frame + add another frame - you have your loaded frame. Costs: 35 Euro for the picture frame, 30 for basotect, 10 for the rubber mat + 2 kg active coal pellets - if you dont pick these pellets - you could go for other filling materials (cloth, rock wool.) ( Overall Price for 0,5 qm Panel: About 80 euro including the glue.) I did build some of these already, but active coal is very expensive (but very lightweight.) The ideas of acoustic field is quiete good because the overall surface of active coal is so high.) Anyway - this approach seems a lot cheaper - which is why i will go with my next build with the floating gummi "punchball" approach mentioned here.
So awesome! Thanks for continually putting out great videos like this. Love the Newell-inspired content. You've motivated me to build a panel version of this for my room.
Great Video Mr Wilson.. :) I think you've added value to the book, by including current pricing of the materials and talking about alternatives.. perhaps a link to the book would be helpful..
What about using 20-40cm (8 to 16 inches) of absorbing material? In the air gap between walls for isolation. I think dense heavy materials like lead or steel can be quite "thin" but air gap and the need to fill that air gap with absorbers cannot be avoided. As in to get those lowest octaves isn't it more effective to weaken those waves inside the cavity, instead of smaller air gaps and thicker walls. Comparing the same amount of space. Cost I am not so sure (how thinner walls with lead or steel and other dense materials compare to the cost of thicker regular concrete walls). In any case, that is not for regular home owners XD I think the cheapest would be an underground studio. Otherwise, having walls of several feet filled with soil or sand (like the earthship homes, with tires filled with soil).
I have always thought earthship homes and other dirt or underground structures would be a great option and maybe even more budget friendly. Are you working on designing a studio or just exploring options?
I like this idea a lot. When dividing a large space (ie a barn), this will be relatively easy way to make a control room or smaller recording areas I presume..
Attempting to absorb frequencies down to 30hz makes a lot of sense when you are dealing with extremely rigid concrete block walls, but for 99% of viewers, their structure is passing nearly all of that energy right out of the room already, even with double layer 5/8" sheetrock.
Will the “acoustic” part work without double wall isolation system? what I mean is If we are talking about acoustics for a control room - how good this system work if it’s implemented from the airgap part but on top of the standard walls?
Great info, I am just wondering how to build this design, The challenge being the insulation/MLV/DRywall etc on this inside area of the Studs. I presume you would have to build the wall section on the ground put all the stuff on it then left it up into place? any thoughts on that? Also There has been discussion that sandwiching MLV between drywall would make that use not work as it has to hang freely.
Is the air gap between the wall and panel sealed? (As of the triple leaf effect?) What are internal dimensions of each panels sealed space (as Depth is 4" but what about height & Width ) As assuming this will have a massive effect on the tuning of them?
I had some discourse with Dennis at Acoustic Fields, after I saw that he started offering 1/2 size bass absorbers. He said the size doesn't matter much. It's having enough depth for low freq. absorption that is important. The density of the material is the same, whatever the panel size. The vibration of the panel itself barely affects bass, and only attenuates and/or reflects the mids and highs. Bass is a long (30 feet- bigger than most small rooms)) pressure wave and needs depth and dense mass to absorb. Hope this helps.
I don't think this type of Absorber needs tuning, because they are "broadband". The goal is to stop low freq. energy/reflections. A Helmholtz "resonator" does need tuning.
Yes, but the triple leaf effect happens when you put drywall in between your double stud wall. The acoustic wall is sealed and sits away from the acoustic wall. It is not technically your isolation system.
Great insight, but how can we take the concepts and design a budget studio in that 15x20 space? Should I make 1 small live room, one small control, or Should it be all one room where drums amps and vocals are recorded in the “live” end and control, mixing, etc is in the dead end? $5k is way out of my budget. I just want to not piss off the neighbors
I use one room and did not do this design. Newell designs are hardcore and used for high end studios. You could use his design for a neutral room and probably get great results as a mixed use room. His control room design would also double as a great recording room in a home studio. The key is do you value great live acoustics for recording or super accurate listening for mixing and mastering. I find most people lean more to one side of that spectrum.
Metric system measure will be helpful for more people on this planet. I suppose the population in a different solar system, "feet" will embrace "feet" as the primary measure of distance.
How does the mass loaded vinyl move if it is tightly sandwiched between these Knauf boards. I thought it works by hanging free from contact both sides to 'give in' (like the punching bag analogy) to the wave.
@@soundproofyourstudio I've seen some comments made by manufacturers of MLV that it needs to hang free to vibrate. I believe to sandwich MLV is to use the product as a barrier, to keep sound out, but to hang it lose it behaves as an absorber of sound, sealing the edges of this lose sheet against air movement utilizes both properties. I wonder if this concept applies: an arrow hitting a loose animal hide and catching the arrow vs a taut skin allowing the arrow to pass through. That was a defensive technique used 100s of years ago.
I will even say more - this design does not absorb low frequencies at all. This is an insulating shell. It seems that the author did not understand anything from this book.
High frequency will not pass through the drywall. They will reflect. Most high frequencies would be absorbed in the first layer of insulation mineral wool or cotton fiber.
I have enjoyed learning about sound proofing, but some of the info will not help in my project. I'm currently building a sound proofing generator box. Do you have any advice for low-cost materials for low fqcy? I'm thinking of using 2" mineral wool on 1/2 OSD board.
You can use similar ideas for a soundproof box. Remember to have mass, spring mass and keep it air tight. The door will need to be heavy and air tight as well. Best of luck!
I actually went to the trouble of giving you my email hoping your FREE Acoustic Treatment Guide would be enlightening. But it's just a 4 page leaflet. It feels a bit dishonest to make so much out of that to be honest. But other than that: keep up the good work.
@@soundproofyourstudio No... Let's get real. It's meant as a LEAD MAGNET. To subsequently sell a product. And @aukehoekstra9834 just told you that your lead magnet is too thin/weak to provide actual value.
5kg = 11lbs, isn't it? Not "1lbs", as was stated in the video. Can you expect useful advices on acoustics from someone who can't count? Who knows... But this "design" has nothing to do with Newell's work. Looks more like one generated by AI. P.S.: If someone watched to the end - was it said that this whole structure must be airtight? So air should not be able to get behind this "acoustic" wall, because otherwise it'll turn into a pile of expensive junk. Please, let me know!
The 30hz will be there at the source and in the volume of the space. The idea is by absorbtion it will not set the room in motion, creating unwanted modes.
WARNING! This is isolation shell, and it DOESN'T absorb low frequencies. It's block the transmission, on the expense of reflect the sound back to the room. This author of this video have no clue about acoustic principles, even can't read the works which were written in the simplest language possible by those who really understand the issue. So be carefull, as Philip Newell said - be aware of people, who use the word SOUNDPROOF, don't let them make SOUNDFOOLS of you ;)
@@chinmeysway It is actually a very good book. Philip Newell is a brilliant designer of cheap, yet powerful and cost-effective acoustic treatments. But you can't just take individual parts of his design, put them together in a random order and hope that it will work (like the author of this video did). In Newell's book, Recording Studio Design, you won't find examples like the ones shown in the video. This is an absolute profanation of his designs.
I agree I the whole system works together as a whole, but youtube vids can only be so long. Soundproofing is good for search but sound isolation is a much better term.
This is glass mineral wool with a binder. It weighs 3lbs per unit. It’s a fraction of the density of drywall. This stuff cannot block sound reflectively. You are suggesting that a company like GIK acoustics, which sells this for bass traps, doesn’t have a clue. Dig into the physics or cite your sources for suggesting this material is reflective and not absorbing.
Whaaaaaat?? As soon as you use screws to hold your contact adhesive made wall to the studs you are transfering lots of sound through the screws Ive watched a few of your videos and you are the dangerous kind of advice giver, the kind who is just repeating stuff in "youre understanding"
I’m sure this will drive those people that have the money to design a room to buy the book highlighted in the video as it is a very small fraction of what they will ultimately spend.
Valuable intellectual property, if it’s your bread and butter, isn’t typically published in a widely available text. Anyone capable of putting a measurable dent in Philip’s bank account isn’t going to sweat paying a few bucks for his book. I’ll be buying it based on this video alone, something I wouldn’t have done if he hadn’t posted it.

PSI AVAA’s are pressure traps that work. Not cheap.. but worth it when space is limited
Have you used them. Very curious at how effective they are
@@soundproofyourstudio they certainly help with frequency response and decay time down verrry low. But you have put a lot of effort into placing them
It would be good to see an SPL graph of broadbased noise recorded from the exterior of this device
This is not an isolation system. It works as an absorber.
I like this idea a lot. When dividing a large space (ie a barn), this will be relatively easy way to make a control room or smaller recording areas I presume..
Well the wall really works as an acoustic absorber not so much an isolation wall.
Awesome video man
Appreciate it!

Very good point! If your room is not soundproof most low frequencies just go through light weight walls thus improving internal acoustics.
Will the “acoustic” part work without double wall isolation system? what I mean is If we are talking about acoustics for a control room - how good this system work if it’s implemented from the airgap part but on top of the standard walls?
Good question, no I wouldn’t do that. They are two separate systems.
Hi does this absorb from outside noise as well? Tractors, semi trucks specifically which are always an ungodly frequencies below 60hz
It has mass so will help with isolation but should not be used I. Place of isolation

It still moves because it is a material that dampens sound. Honestly I have seen data where the sandwich performs better than limply hung.

What about them? Each part of the wall system will absorb different frequencies according to Newell.
Is it cold in your studio?
