- NOTE: This is for recording DRY sound effect source material and it's NOT for recording music (if that is what you want to do, you should not treat the entire room like I have =)
While building my sound recording room I made some sound recording tests for all the various steps of treating the room to absorb sound reflection. This video goes through what I did and compares the sound result by demonstrating speech and hand claps.
In order not to make the speech volume way too low I used fast limiter and increased the audio gain by 20 dB because the hand clap peaks are extremely loud compared to the speech. I also increased gain of the speech segments by another 6 dB.
At 17:25 in the video you can find a quick comparison between the different stages.
The purpose of this room is to record dry source material with no echo or reverb (at least very little of it) and also isolating from disturbing sounds. I've built this room in my detached garage so it's a separate room within the garage. It does totally remove the sounds of trucks or lorries driving past right outside the garage and I also have to be aware of airplanes when recording very silent sounds like pen / paper etc.
Still, I'm happy with the performance of this room as it is now and I am creating many sounds for libraries and sound design in this room at the moment.
The pyramid foam I used for the final layer is t.akustik SA-P80 (www.thomann.de/...)

Ty
you're the man
the standard housing insulation sounded the best.... no boxy reflection
I felt the same way. Interesting to see I wasn't the only one.
Same
100%. Should have layered the outside of the room to knock down how much the outside world could hear and just put super thin acoustic false wall fabric on the insulation
Uneven Sleeves if that was his goal he should have just put another layer of insulation or mineral wool on the walls and and covered them in fabric. This absorbs the sound was better than form.
Yes but If we calculate a recording room acoustic problems and after your listening room acoustic problems , the result will be terrible. It's more than enough if our listening rooms have problems. The recording should be very proper
Wait a second... just imagine how hot that room gets
Well no actually, because it is well insulated it will prevent the outside heat from coming in I guess
@@landonoriginals ah, so its a fridge?
@ lol
Recording booths do get hot though. I believe sound waves are still energy and when they encounter irregularities in their travels (just like in a recording booth) some of that energy translates into thermal energy. I know that added to body heat in my tiny booth, I get hot very quickly. But this is quite big though, I'd be interested to know how hot this gets and how/if its ventilated!
@@SimonTebbenhamMusic they get hot from electric equipment. the energy in sound waves is negligible compared to heat inefficiencies from equipment.
oh shit I forgot to build the door! HALP
Knobody can hear you scream for halp!
Dude is serial killer...... See the drain in the floor for blood.....
Bearshare lol brings back memories
"I see the problem."
🤣
that clap sound is so dry, i had to lube my ears to hear it
12:27 super amazing no decay good room🤙🏽
this is where he brings his victims
no one can hear their screams...
The Dutch organized crime scene actually built some insulated shipping containers for torturing their victims. It was discovered in mid 2020...
😂
thought so
I watched this video 3 years ago... but earlier this year I got a chance to build a small home studio in Spain.
Similar construction, but with a control room. We found it easiest to create the walls flat on the floor... stretch and fasten the fabric... and then assemble the room. Finishing each wall (on the floor) was SO easy.
We went for a trapezoidal design with a sloped ceiling... but still, it was a surprisingly simple build. The control room was built separately and between the two facing windows of each room we used blackout material to avoid a mechanical connection between the rooms. So, they are effectively only air coupled via a very short tunnel of material.
After it was finished there were a couple of things we would have done differently, if we were doing it again. But overall, we were surprised with just how well it turned out.
Thanks for the inspiration.
4:46 he = outside of this room is my garage and outside garage is reality
me = interesting
To all those musicians/producers watching this. He DID Soundproofed the room with the rockwool, However; foam is not acoustic treatment. They are rather diffusers for echoes and reverberations. But keep in mind the material they are made up can cause severe damage to your lungs eventually. Do not use this foam ever.
Thanks for this comment!
I was just going to order these. Can u please suggest me which one i should use ?
Soo great to have that 1:1 comparison of the claps! Quite interesting that - in my impression - the room just with insulation is dryer than insulation + blankets. Have fun with the room!
Let's not mince words here. You did a fantastic job on this Room (and all by yourself? Wowzers!) Many here will nit-pick things about it (such as it should have had a trapezoidal-shaped angles on the 4 opposing-walls and ceiling to floor ... adding a floating-floor frame layer... yadda-yadda-yadda) or choices of building/finishing materials. But no one can argue that you stepped up and made this thing happen! Good luck with your projects and may it be a place people will *want* to use for future client projects and Foley sound-work. Bravo! 😊👍
I really appreciate this comment =) Thank you!
"NOTE: This is for recording DRY sound effect source material and it's NOT for recording music (if that is what you want to do, you should not treat the entire room like I have =)"
That saved u from my dislike lmao :D If this is the intention, great build, great video!
ohhh okay, okay fair enough!! I can feel that
You can get dry without sounding completely dull like the results here though!
Are you saying to get that professional sound he could have did half the work? what would you have NOT done and still would have had quality recordings?
i need this room so i can scream loudly in horror games and yell curse words without my parents hearing me
Your English and pronunciation is INSANELY GOOD! with virtually no accent either, that sound room really was what we call "A Labour Of Love" so much work and effort
100% can hear he is from Sweden :) And you know what, that's totally fine.

Who cares if he has an accent…?
This is an amazing space. like the how you test the space with a clap, it's very useful to get a feel for the room. I've used that so much that I actually find my self randomly doing it in any space I walk into just to check acoustics.

the only video in WHOLE entire youtube that shows how does it sound to have a room treated.
yooo, where have I seen you before?? this is wild!
Anyway... this is NOT the greatest treated room, imo. It's nice, but kinda... forgive me for saying, tacky(?) There are MANY other tactics that could've been taken, and I feel like this was the most *of course*/basic types of "treatment" without a lot of research
I'm everywhere on youtube. Yea maybe. I think it could do some solidness in there. I can only imagine solid vocals, percussions and guitar specially if recording with a mic
this was the most impressive video we have ever seen on sound treatments. wow. amazingly well done!!!
Thank you very much - I appreciate that you took the time to drop a comment and I'm glad you like it.
I'd like an edit of this video of just the claps. That way it looks like he's magically clapping the room together and we all hear the differences.
That would be tight
You put a lot of work in there and it's well done. Now only your room is too dry for a lot of applications. You actually want some reflections for ADR and especially for Foley recordings (inside). Of course it's cool to have a really dry room for voice over, but don't kill it too much. I would remove the foam and install a few QR diffusers on the ceiling and maybe on one of the walls. I think the recordings would sound more natural and you'll have less problems to integrate them to movies or other projects. Tell me more
+Dave Hassel Hi Dave - thanks a lot your tips! I will test with diffusers as well - I am still learning as I go and I won't be doing much active foley to picture but I suspect the diffusers will add some qualities to the sounds rather than having them completely dry. I do a lot of post processing on the sounds for sound effect design now so most of the time the total dryness is quite nice to have, but I admit that in some cases the sound gets too isolated. Thanks again!
+Dave Hassel Was thinking the same thing. Somewhere in the middle of the deadening sequence, the sound had a good balance. When I built a mastering studio with plans from an acoustician, designed to allow for analytical listening, the RT60 was brought from 2.5 seconds down to 0.25, which involved a lot of absorptive materials and bass trapping. About 1000 litres of bass trapping, since all frequencies are equally important in mastering. Had every surface been covered in the final layering, it wouldn't have been good for much, except as a big voice over room. A worthy effort, and since the isolation factor is taken care of now (hopefully?) adding back a little life into the room, by way of diffusion, and perhaps adjustable surfaces, it should become a very useable space indeed. Loved the Sanken demonstration, Imphenzia. Would love to listen to recordings of bats and mice pitched down like that :)
I think aside from not using drywall for isolation, he was correct in killing the reverb for folly work. Some folly sounds sure better dry so that the sound designer can add the reverb to fit the environment better. Reverb also locks the "environment" of the sound. Meaning the listener would instinctively know that it was recorded indoor. Replicating footsteps on a pavement outdoors for example would not work if we hear the room's environment. If he wanted to introduce reverb because he is mimicking indoor sounds, he can roll up the rug, bring in hard surfaces or add it in post. I think Folly work, although related to ADR and music or song recording is a bit different in it's application and it's specific requirements. Library banks of sound needs to be adjustable to countless environments. something that is not needed in ADR and music recording.

I'm from Oz, and I take my acoustic design ideas from watching The Australian Parliament upper and lower chambers. Its partially built underground, and the chambers are several stories high, with skylights. The acoustic treatment of those "1,000's of Cubic Meters" of space is a wonder to behold. Echo, Reverb, Sound Envelope are barely sensed. Look at the walls, and you will know what I mean. Same goes for the Sydney Opera House. Another acoustic wonder, where the empty chairs mimic a full audience.
I feel like you would go insane in is room
Yeah, sometimes stand in there recording sound effects and I wonder what the **** I'm doing smashing fruit in a padded room!! =)
most people are fine even in those special sound cancellation rooms but for some people it can make them feel very claustrophobic because the room sounds small
also black is sadness
+Oneness100 He made it clear that it wasn't a listening room. He is looking for natural sound to record and I think he did a brilliant job.
Hi, it's not for tracking vocals, instruments or listening in. I smash fruit windows and car doors with a sledge hammer in there =) I need the dry sound with as little reflection as possible. I introduce diffusion and other elements (e.g. like metal cabinet to get metal reverberation) when needed for some recordings.
Nice video! The standard insulation sounded much better than the acoustic foam to my ears. I built all my absorbers myself.
Yes, that was a lesson learned during the build (it was a trial and error approach) - if I relocate I may decide to use insulation and cover it with perforated fabric - it would save money and time.

I can still hear the echo. I've my hearing test before and the room they placed me in was eerie quiet! It was so weird that I couldn't even hear my own echo
I BUILT A ROOM SO DEAD THAT MY PARTNER COULD NOT STAY IN IT LONG. You could hear the sounds of your body that you never heard before. I loved it. You can always liven up a room but you can't always deaden one. Sorry caps stuck and I didn't fix it in post ..lol
The Raw insulation sounded the best!
really? explain what you would have and would not have done here?
@@Dynamics4success I was just stating that I liked the sound of the raw insulation, if soundproofing wasn't an issue he could could have just covered the walls with a fabric after the insulation and got a great result almost like being in one big acoustic panel. The final result he got was great as well.
i think he was also wanting sound to not escape the room thats why.
I realize you spent alot of time and money on this and that is highly valued and respected. There are so many people who say so many diferent things its hard to know what is right. Let me say this i have built and sold over 10 studios and habe been professionally recording and mixing major artists for over 20 years and im now finally understanding the reality of accoustics.with that being said there are two very different and at the same time important thinhs to kmow 1 sound proffing and 2 sound absorbrion and with that i should add 3 low freqency wich is completely seperate from every thing else. To sound proof building a room inside a room is preferable also decoupling the walls making sure to have air space between any wall now for absorption what you did was fine i actually would have used sound board instead of curtains because its much faster and less expensive and for the foam great idea except the choice you choose. See i would have rather used wedges and made sure that every single 12×12 square was in a differnt direction kinda the same thought process as a stealth fighter jet wave forms are like sonar its all about bouncing off simalar surfaces and trying to deflect sound and scatter the wave form. If you listen close with what you have it is DEAD. But because all foam is the same there is still resonate artifacts in the mid and high frequency which translate to sibalence of you listen close if you were to use directional wedges and change the pattern it would split up those frequencies amd become an ideal vocal both now a vocal both is far different from a recording booth for lets say drums you would actually wand that room for drums or guitar to be less dead you want to hear a little normality in the room but still controll the reflections that are negative and that can be done by absorbtion basicly and soft material that does not habe a flat surfave and the deeper the material the lower the frequency but to place them only in the areas of the room were you hear bounce back thats not apealinh to the ears. But your on the right track. Just keep these thoughts in mind
End result looks cool too

This guy takes audio snobbery to a whole new level.
How do you breathe?! I mean, no windows, no dors, no fresh air...
WildMania open the door after a session
I am just experimenting with DIY microphones (electret capsules and MAX9814 mic preamp), and have problem with echoing. Not to mention high traffic near my house + neighbours dog. Not ideal condition for making good sound samples, but sufficiently good for most of UA-cam videos. Thanks, you gave me inspiration for making at least part of my room less reflective. Only problem which can't be solved is outdoor trafic (nearby road), so I should to record nightime - when traffic is relatively low. Thank you for video and for answer.
BTW, subscribed to your channel. Plenty of good stuff.

He takes a deep breath, enters the booth and records the whole session one take.
Seems like people are pretty misunderstanding of the fact that you WILL get the police called on you if you're screaming, crashing glass, and hitting things with sledgehammers. Keeping all of that sound in, is 100% necessary, as well as common decency for children and other family members. Well done! I rather enjoyed this video.
A few notes :
What was the goal ? Was it to isolate sound from outside world ? If so why not measure the DB loss between inside and a few sample points outside with a known measured sound dB inside @ say 100 HZ 1000 Hz and 10,000 Hz ? This may give you an idea of how much isolation you are getting .
If the goal was to obtain a good internal sound for recording the first question is what constitutes a good sound within a recorded audible track ? This is not so easy to answer. Sometimes liveliness is actually required and specific non linearity in frequency can work with specific microphones but ignoring this for the moment .
I closed my eyes and listened to the ending claps and asked myself what was most pleasurable . The sound with some reverberation ( the lining cloth layers ) seemed to have a nice timber to it . The extra foam completely absorbed the higher frequency giving a very dead sound . You can see the tail on the recorded signals shifting about and shortening as the material is added.
Ideally, one might want a room that can be altered to have flexibility to get a sound that is required and having a good isolation from outside world but these are different requirements. For example a room with very tight base is normally always positive and then the ability to add and subtract the liveliness at different frequencies.. You may wish to have some harder reflective surfaces that can be added to make the room more alive at certain frequencies..
Did you examine the ratio of room W x L x H with say a Bonello graph to reduce modal problems ?
Hi, my most prioritized goal was to reduce sound reflection / reverb. I only use the room to record source material for sound effects and not for any music purposes. I can always add delay and reverb afterwards. I'm happy with the result and when I record shattering glass, crushing metal, voices, etc. I get very little reverb so I can pitch shift and process the audio a lot.
Secondly I wanted to reduce sound from the outside world. I was less effective in doing this so it was a lesson learned. Luckily enough I live in a fairly quiet location so especially in the evenings there is little sound that comes in with the exception of the odd airplane or car which are infrequent. Unfortunately sound also makes it out so during monster screaming sessions any pedestrian outside my garage may wonder what the **** is going on =)
I looked into the ratio of the room but more than anything the space I had available had to decide how large it should be. I built this inside a 85 sqm garage where half the garage has a 3m+ ceiling height so I made sure to utilize that space best possible. Since I was going for minimizing any reflections I figured it had less significance. Also, I don't produce consistent tones e.g. musical instruments etc, so it should not be much of a problem.
ty - Can you measure the inside dimensions of the room in metres?
Length: 3.5m, Width: 2.6m, Height 2.3m (interior with foam. will vary somewhat since the 80mm foam is pyramid shape so it'll be +- 1dm or so.
The Kaveman. I do not think his main objective is isolation, I understand why he opted for a completely dry room for folly work. Unlike music, song recording, and Voice overs for commercials or avp, ADR and folly work needs to be able to mimic countless environments including outdoors. Someone talking outdoor in the streets or mimicking footsteps on the driveway for example will sound wrong if we hear the studio's reverberation. We'll know it was recorded indoor. I see a lot of comment from music and VO artist who may not be familiar with sound design and folly work. I am assuming that if he needs to mimic indoor sound, he would either, roll up the carpet or put in a hard surface, or add reverb in post. Sometimes even particular sounds normally associated indoors should be recorded dry so that the sound designer has more room to match the sound to a particular environment and has more room to maneuver when designing sound for a particular shot. Although sound recording for music and Voice Over is related to ADR and Sound Design, they present different needs and different applications.
Follywork is part of sound design. Certain applications and requirements are needed that are not needed for music recording.
I'm learning a lot thanks to you, I am from Venezuela and the economy does not help to pay in patreon but I support you here
it looks like a great place to get dry recordings. No ventilation?

DUUUUUUDE you're the same guy i watched waay back??? omg!
i watched this video when my dream was to have my own recording studio. i thought - oh man! what this guy did is really something i can try...
now i'm watching your 10 minute challenge videos!
Thank you for showing the waveforms! That really helped me see the exact changes.
I wouldn't spend much time in that room dude. No windows, enclosed space where all that foam is just off gassing constantly into your lungs.
Not to mention the microscopic fibres from the insulation
Heaven For Me
Right? Next time use cork.
Maybe he should bring in a fan or two😂
Off gassing will subside after several hundred years. Then you may begin recording.
The room sounds great. first stage was too dampened, second with the wood was too reflective but the third and fourth stage of development was nice and clear to my ears. Great job, great video
Matt van den Ham the room dosent sound at all
Jaime den Ham That is why is sounds great. It might sound a little dead in the room,but people are listening to the recording in their OWN reflective rooms (a double wammy of added room acoustics is not natural). The over exaggerated echo I heard in the bare room doesn't sound natural(I am hearing the recorded echo and what my room adds on top of that) because in reality we are never listening to 2 different rooms at the same time,nor compounding what the room adds.

@@gordthor5351 the room doesn't sound at all. he put a recorder all night and the room did not make any sound.

The way to of made this cheaper and better is at the sound blanket stage instead of using the black drape/ blankets.. you could of used foam backed cord carpet which is about $2 or 3$ a sq metre. this will staple onto your wood but also be a totally finished surface.. the thomman acoustic foam isn't required here and as you can here from the video doesn't make much difference from the rock wool stage. the carpet looks more professional and can be trimmed with wood if required to make it look even better.. But great video! I have a similar size post production suite. Another tip.. for a less dead room use split face wood tiles on a couple of the walls.
the progress and improvement on the room is amazing, great video man!

No floating floor.
Man you killed it a the end of the video. The most precious part. Thank you
You're welcome - thanks!

You're actually creating multiple layers of sound diffusion with a bit of sound absorption. Actual sound absorption, which will stop the sound waves from traveling, works most efficiently by changing phases, ie: sound traveling through air space, into solid, back to air space, etc, preferably multiple times, with the "solid" being as much mass as possible, and the air space being as much vacuum as possible. While sound absorption isn't the easiest thing to achieve, I'd suggest using mass loaded vinyl (MLV) on the outside of the entire room with an air gap between the outer wood and the mass loaded vinyl. That will be the easiest method to deaden the sound to the outside at this point... if that is your intention. Otherwise, you've created a beautifully diffused sound room for recording, which is more important than sound absorption.. depending on how much you want to piss of your neighbors ;-)
I think what you meant is sound isolation and not absorption. What you described as sound absorption is actually for sound isolation. Absorption is the converting of mechanical sound energy to heat. Sound absorption like sound diffusion (the scattering of sound waves) is mainly for sound treatment. The use of mass, air gaps, MLV etc. are mainly for attenuation of sound traveling inside and outside the room. That is sound isolation.
Gives himself a slow clap at the end, lol
If you want the LEDs to be as quiet as possible then you'll need to have DC powered ones with your AC voltage conversion done outside of the room. That will prevent any coil whine in the room.
Thanks for the tip! I also noticed I need to replace the LED lights with other lights with higher update frequency because they flicker a lot when I record video in there, especially in slow-motion high FPS.
You might be able to put a large smoothing capacitor across the positive and negative terminals. It sounds like the lights might be using a cheap switch mode power supply which would leave a ripple, or a LARGE ripple, in the power flow. You might be able to grab a mid quality computer PSU and tap into the 6/8 pin or molex if you want something easy to find. Computer PSUs should have quite clean power.
This is what a lot of power supplies look like. Or worse...

It appears that you have constructed your room such that the walls a parallel. It would be greatly improved (with no cost) by simply making the side walls anti parallel. That is to say not parallel with each other. Echoes won't propagate, they drop away quickly.
I agree, I was contemplating non-parallel walls but decided against it. My reasoning was that I was going for a dead room for the sound effects, if it was a studio I would definitely have put more efforts into the proportions and shape. Also, I wanted to optimize the size in my garage and speed up the build. But thanks for taking your time to comment - anyone reading this should definitely consider the shape.

Any recording for more than 12 minutes and the person will pass out from lack of oxygen. :-) Great Video!!!
Electric staple gun, Man!
thumbs up on that one... the broken manual one was terrible =)

Yeah
That is perfect for recording videos and streaming so that neighbours won't complain
Yes, keeps the videos quiet and the neighbors happy. Mind though, the interior makes you go a bit crazy if you spend too much time in there =) Probably want to decorate it a bit!
How effective did you find the soundproofing to be? I'm busy with a similar project for a live studio room, any advise?
I think the glasswool itself just work fine.

it's amazing to just hear the sound getting better and better throughout the video. great job
Funny, it sounded best with the exposed insulation.
Yeah, that was one lesson learned =) So maybe just insulation covered by perforated fabric to make it look nicer (and prevent itchy fibers) would be best.
yes thats true best absortion due to trillion ways for the waves to dampen. the problem is that fiberglass is toxic and needs to be sealed

This is the most satisfying unsatisfying video I’ve ever watched
It's like an anechoic Tardis :)
Last studio I was in was a £1m studio... And omg was it strange on the senses. It was beautiful aswell. Wish I could have my own
Its more an anechoid chamber than a recording room...no?..
In general and professional terms recording room is way to different concept from dead / anechoic rooms. You want reverb, you like it, you need it. But it depend on what is the purpose of this room.
As far as it's intended to be Foley Room - he is on the right way.
+1 - no doubt)
Yes!!
I'm no sound expert but the graph seemed to suggest that the blankets reflected more sound than the housing insulation making it 2 steps forward one step back .
THAT IS ALOT OF FOAM
needs. more. foam.
The comparison at 17:23 is godly.
Test test, check check...
Test... test, test, you're testin' my love for you.
Check, check, you're checkin' to see if I'm true.
Test one, test two, test three, test four!
You test me like the water in El Salvador!
There is still too much reflection going on in low/low-mid frequency spectrum, this is problem especially with louder sounds, and will result in "cheap, boxy" sound that cannot be fixed by any postproduction.
Room should have not parallel walls, and also it would be better to use less cubeic room (i.e. use 1:1.14:1.39 ratio, which is perfect to reduce standing waves). It is very hard to achieve totaly dry room just by using absorption material, all an-echoic chambers base more on reflecting and trapping sound waves, than on absorption itself. Easy fix is to use some irregular surface (free standing panels) inside the room to scatter and diffuse sound, it would help dramaticlly.
However great video!
There's sound proofing then insanity.
I actually like the room with only the isolation foam. The extra acoustic pads just dont sound right to me.
"Pretty much nothing rocket sciencey about that" lol
Wow...the first insulation thingy really worked well.
I need this for gaming
www.lavocalbooths.com/
....fapping you mean?
Im not an expert but isnt there something like "to much isolation"?
I read somewhere that this will absorb the high frequencies way more than the mids and gives an unbalanced feel
Yes, for most recording this would be too much, but I record sound effects in there that need to be as dry as possible.
@@Imphenzia ah ok. i see
its sounds like you are from sweden i am from sweden so i can hear that
Yes, Sweden it is =)
Looks gorgeous
Thanks!
but hey, it's been 8 months now, how do you feel about it ? Do you feel like you could've improved things from the beginning watching back from today ? :)
Square room = bad acoustics. Doesn't matter how you treat it.
Should I have just left the room with only plaster walls you mean =) Joking aside, I had in mind to make an odd shaped room but it would have required a lot more planning. Since I aimed to *remove* as many reflections I could I figured that it should still be OK with a rectangular room. If it was meant as a studio (and not a dry foley room) I would have investigated the shape a lot more.
Uncle Benja so what is the best shape sir im looking to build a room
+Migalouch Garcia Just avoid square rooms. Rectanglular rooms are fine. Also, the bigger the space, the better.
I don't think there is one "best" room shape for acoustics. (Atleast not one you'll find in the average home.)
Another note is to avoid foam. I see many people on youtube using foam for acoustic treatment and it makes me mad. Foam has it's uses, but is really only good for absorbing high frequencies. High frequencies are rarely an issue in home studios. Rockwool basstraps are a much better alternative that can be made cheaply and work with broader frequencies. Just make sure to make them nice and thick if you do make them. (Lots of tutorials on youtube show people making them much too thin to be effective.) Also make sure there is atleast a 4" gap from the rockwool to the wall.
Hope that helps. :)
+Migalouch Garcia Also the higher the ceilings, the better. Avoid really low ones if possible.
Uncle Benja thanks appreciate it
id go with tilted walls, not square, not parrallel to each other, wooden panel floor, tilted ceiling too, and would stop at blankets and dont bother with foam.. looks like overkill but I hope it works for what you need it for..
Overkill and to dry for tracking drums
3:37 Eargasm
honestly... it sounded REALLY nice ESPECIALLY in comparison
WOW That comparison was very impressive!!! even though you used an inconsistent source (your hands clapping) you could still tell a huge difference
Thanks - yes, a more consistent impulse would have been much better to use.

A lot cheaper to put a mic at the end of a tube roll of towels
I think if you used the housing installation with a little bit of the foam strategically spaced throughout the room you would get the best sound. The all foam sounded too "tight" IMO.
16:38 "I was thinking to capture any of the bounces to go off the walls."
WHAT SOUND IS BOUNCING OFF YOUR WALLS? YOU DONT HAVE ANY REFLECTION!
Now the last issue to resolve is a huuuuge standing wave in the bass. What's wondering is that till you mounted a foams, it was quite quieter.
All you miss is a bathtub and 1 ton of salt
I just wanna blast music without people complaining
Before 2:41

At 15:11 15:18 to 21 i can hear a truck rumble passing, lots of bass. It would be nearly impossible for you to cut these from the inside. What you need is either a floating floor couple with basse trap ( i mean real one not the foam crap, or some sort of camera that can tell ypu when truck are coming so you dont waste time on take, id personnaly go with a web cam.
Colosphonium I heard that too.
The fist installation of the wall insulation looks like a bunker lol. Kinda resembles stone.
This build is nice, but you will get breathing problems in there. NEVER ever leave rockwool exposed to air that a person is breathing.
Particles of these mats will find their way into the room and you will breathe them in. You definately don't want that to happen.
Always enclose rockwool with at least a layer of thin material like thin plastic foil. The reflections you get from that are in the upper spectrum and will get absorbed by the material above it.
Like the cloth and the foam you have there. Rockwool is meant to absorb well below that. So absorption-wise you should be fine.
Did you take acoustic measurments of the room ?
Must be a very hot room during spring and summer 😋
That wool makes all the difference.
THANK YOU MAN.🔥✔
Im going to do the same thing with walls and ceiling, sort of. I have a room made from 2 foot thick concrete ground level not a basement. It used to be a vault from the early 1900's. Using Rockwool Safe n sound insulation placed in wooden framing. Then will use Guildford of Maine acoustic fabric over that. I want the sound wave to pass through the fabric and absorb into the insulation. Then will build bass traps in corner with Rockwool. I have a very heavy vault door and two inner doors which come together I'll put eps foam onto then put the regular sound foam 2" on to this will act as the sound diffusion. Lastly I have tile on the floor I will put some sort of rug, haven't figured this part out yet. In conclusion I really liked your video because I was interested in seeing someone do something similar to what I will be undertaking soon. All the other videos are just for the small panels that hang onto walls. I may video this process as well so you can see a comparison. The room I am doing is roughly 9 meters long by 6.5 meters wide by 6.5 meters tall.
That shot with the knife, oooh my...
Well done! I want to try building something like this is the future when I have some 💰
the difference between the beggining and 1st step is real crazy
Yeah, after the first step it was probably more dead than the end result =)
That's a great sound fx room. Should give you total control over the finished sound with processing.
Good work.
Yes, the sounds come out quite clean indeed. I should possibly have isolated the room a bit more from the outside world though. Airplanes and some cars (although the street is not busy at all) still come through at times. Thanks!
I have a kind of dumb question. The goal here is not only to make the room dry, but also to shield it from outside noise. And of course the wood between the wool makes it easier, to just push it in between.
But wouldn't the isolation be better, if the whole area was insulation?
Or does the wood isolate just as good?
That's not a dumb question. Main goal was to make it dry and secondary was shielding from outside noise (it's not so noisy in my area, especially in the evenings which is when I most often record). I would have liked to achieve better isolation and I believe suspended (rubber cushioned) blaster boards with air columns between would have done a better job for that. The wood is still needed at intervals and 600mm is a common standard between the studs/beams. It's for structural integrity of the frame.
