Can you show us how to build a bass player trap
SuperMrdumm that made my day
***** Got an even better one...
-Big cardboard box
-A stick to open the box hinge like
-String attached to stick
-Put desired amount of beer... Can be just one bottle or even a can of any beer brand...
-Wait and pull.
tuck234 Hey did in an earlier episode. Laserpointer pointing at a wall. Done.
Pim Schilz Thats pretty good haha XD
+Pim Schilz As a proud bassist, I know I would fall for this. Too elaborate for me.
Man i thought it was gonna be a video on how to catch a wild bass player haha
***** As an alternative to baiting them towards the trap, you can drive them away from every other exit by pinning a piece of sheet music on it.
***** that would be an awesome video and im glad i made someones day
Ernesto montes OOOHHH...you mean a "Bewildered Beast"....anybone.....nobody?....ok..
+anonny mouse Wait- so that string WASN'T magic? Holy shit... ...the guitarists lied to me...
Yeah I actually thought this was going to be about how to trap a bassi... I mean... Meathead
Whenever making DIY sound treatment make damn sure the thing can't catch fire. I don't know if that particular brand of fiberglass is fire rated but keep that in mind. All it takes is one bass player and your studio is done for.
Nejc Kirn They've discovered fire already? My God...
777malkavian this is the end of the world!
NobodyWhatsoever they might light them up because they just realized they have been playing the wrong notes for years without noticing and nobody had the chance to check on them until the recording started.
most fiberglass is used for stoping fire spreading through flats ect , i dont know where the its guna catch fire stuff people thing
but seriously this is not a problem right? since a lot of the 'absorption' is really just kinetic diffusion turning the sound waves into heat inside the fiberglass
Thanks for enlightening me. I always thought a bass trap would be a pizza and a beer in a cage and when the bass player enters the cage you can close it and when he realises he's trapped, you might have finished recording ...
Another useful note for handling fibreglass dust!
If you get too much on your skin, wash yourself with cold water instead of warm/hot water. This is because warm water will cause your pores to expand and the dust is at risk of becoming stuck further inside your skin. This isn't dangerous by any means, it just makes one bitch of an itch!
Yep. Spot-on.
I learned that the hard way! I was helping some friends put a new ceiling in a church and I got that shit all over me(I had to hold it over my head) it itches like nothing else. had to wait hours to get home and shower.
Also; WELL VENTILATED AREA + DUST MASK/RESPIRATOR! That shit makes your lungs itchy!
Imagine pulling pink shit that's been shredded by pests out from behind 40 year old homasote boards. Imagine that being your entire 8 hour work day.
Keyboard Warrior I always feel bad for people who have to handle this stuff daily
Will these also catch trout and other fishes...?
also how do they stand up underwater...?
Are you a bass player?
Arun Kumar
only if they bite.
They will stand up in the water on their own. You just have to ask them nicely
One of the Best Ideas of SoundProofing is "SoundProof Curtains" it actually Block outside Noise coming from Windows. Check Here: livesoundproof.com/best-soundproof-curtains/
James Hetfield called. He says you're due onstage in 5 minutes.
Broken Drummer 😂😂😂
Lol!!!
lol'd
Hahaaa

Everything is more articulated and the cymbals and the hi-hat really shine. Great vid, Glen, I've always been feeling like a caveman when it comes to acoustics!
Rockwool has a slightly higher acoustic dampening factor than fiberglass, so I've used that in the past to good effect. Also the frame can be made from 2x4 wall studs instead of metal. Both of these are cheap and readily available in Home Depot or Lowe's.
Very cool. Another thing I've found works well in certain applications is those heavy moving blankets. Not so much for bass, but I have two hanging on a clothesline behind my kit and they help keep the cymbal reflections in check (as well as hide my washer and dryer and make it look a little more like a studio and not a basement).
Fucking hell, wasn't expecting that big of a change! Without the traps it sounded like you recorded with a built in mic of the camera.
oggel33t was thinking of the same thing. thought i was the only one
cheers
The A/B at the end says it ALL!
Great & powerfully changing vid, Chief! It's a game changer in sure for a lot of DIY-ers! \m/
This is the best video you've made so far. Excellent job glenn
Wow, with the traps the bass drum really rang out in the mix, thanks for making this video because I would have never thought of this on my own because I'm a bass player
great idea with the metal frame. beats sawing, nailing and stapling. just completed a bass trap today and have at least 8 more planned... corners back and top and sides ... diffuses are going to be used as well for mids and highs. Room measurements using analysis software such as REW will tell you the truth about where your problems are and whether you've fixed the issue and how well.
Thanks Glenn. My plan was for timber frames, but this looks easier. I'd love to hear more about your resonator as well.
Yesterday I've done an acoustic treatment job for a practice/recording room.
Bass traps in all the 8 corners, foam at the other end of the room facing the drumset, 6 diffusors behind the drums and some foam on the cealing and at ear level around the drums for getting the first early reflections...the drummer couldn't believe how good the kit sounded, he said he could finally ear the kit and play much better, so it's not just for us techs also the musician will benefit from a good room ;)
That's awesome. You built your traps similar to mine: 4" with metal frames. I used drywall bead which, while less strong, has the advantage of exposing more of the absorbing material. I used 8lb mineral wool. The idea with spacing, which you probably know but others might not is, by spacing the panel in 1-4x the multiple of your panel's thickness, you gain better low end absorption with a slight sacrifice in low mids. This has to measured on a case-by-case basis, though, because when I gapped my cloud too much I got a null. Also, adding FRK (foil, etc) you actually lose some mid-high absorption but gain more low end performance. Be sure not to use more than one layer of FRK (which should face the room) if using multiple sheets of insulation.
i've made these years ago. its great and as an added bonus you save on heating in the winter!!
Love this kind of videos. Just awesome for beginners in the studio building.
Another demonstration that quality gear can't fix shitty drumming. Love your videos! They provide excellent advice without selling out!
Brilliant and very easy , thank you for being a straight shooter with your information.
Thanks, I designed some bass traps for me, but the way you built the frame could improve my project. Also, this is probably the first quiet-Glenn video haha.
Great stuff! Thanks for sharing this stuff with us. Keep it up!
GUYS THIS IS SOOO FRIGGIN EASY!!! WAYYY EASIER THAN WOOD AND NAILS AND STAPLES. GOOD JOB BRO
After reading through the comments, I think you really need to do a video on how to trap an actual bass player. As a bassist myself, I can make some suggestions on what sort of bait would work. Boobs, for starters. They are known for their magical powers...
Hey Glenn, great video. Big fan of your work, yes a lot of the knowledge is available elsewhere but having it put into one easily digestible video is incredibly useful. Any chance you'd consider making a video on placement of these traps and how that would affect sound for tracking? Cheers
Thanks for this man. Extremely helpful. My studio is a small bedroom and I'm having a little trouble with my mixes.
Thank you! This is a great tutorial and I will definitely need this!
Watching this in 2020...your videos have come so far!
Just love that pause between snare and cymbals at 06:38
Hey man! Thank you for your advices, it's really helpful!
Those drum skills will get you into 85% of the other punk bands we play with🤘
Hi, Glenn.
I’ve been watching your channel for some years, and I really admire your philosophy of recording acoustic sounds and making it sound great (hence, I’m commenting on the Bass Traps video).
My question: could a video on super basic acoustic treatment be a possibility? Like, the basics of audio physics, or "You should do this to make your room acoustically accurate" kind of stuff]
If you’ve already done this, I apologize for wasting your time.
Thaank you so much from Japan. Keep it metal!🤘😈
nice, the sound is much sharper and tight ! great job :D
Awesome stuff! This will be my next project.
Dude...wall studs and monkey hooks: YOU ARE A GENIUS!
I've been scouring the internet and the walls of Home Depot trying to find something that requires minimal effort and is also cheap. This is perfect.
Also I had never heard of monkey hooks before, I'm pretty sure you've changed my life in two different ways with this one video, so thank you sir!
Awesome info man. Rather a cleave with idea with using the aluminum studs as the frames. Thank for sharing.
Very useful video. Thanks Glenn!
Love your stuff man keep it coming
Great demonstration, thanks!
Hey Glenn I just wanted to add that you can get the fabric fairly cheap using old sheets from Grandma or thrift stores. You don’t have as much choice on patterns usually but the fabric stores are usually fairly expensive. Cool vid!
Great information for me, thankyou Sir. 🙏🏻👍🏻
Learning from the best while I start my at home studio 👌🏽
Nice work. I need to build some of these. Thanks much.
I see other people have already commented that this is in fact a broadband absorber and not a bass trap so I won't belabor that point.
Main thing I wanted to mention, as I have built a LOT of these things for my studio as well as for other people, is that you can also use a product that is made from compressed rock wool and get a very similar result. It looks about the same but is not yellow. It comes in 3" and 4" thicknesses. It is about half the price of the fiberglass. You have to get it at the building supply places too. The largest maker of it is Roxul.
One other thing. I build mine with a wood frame so I've got something to staple to. I cover the panel first with a layer of 1/2" cotton batting. This acts like a filter to keep all those nasty fibers inside.
Lots of good info on your channel. Love your videos. Keep it up!
Roxul Safe N' Sound is also great if you can't find the stuff Glenn uses. It's not compressed, but it does a wonderful job of deadening sound. If you add a piece of styro insulation for rigidity and sandwich it between two half inch piece of Roxul, you'll have an amazing trap for the same price, maybe a bit cheaper. All of that is available at the big box stores if that's something you have to go with.
Thank you man! I made a studio space out of a shipping container but the acoustics are....pretty bad. Seems like an easy weekend project to build these, Thanks again!!
Yes! Finally! Thanks so much for this! :D
Huge difference, definitely worth the effort and money.
Thanks Glenn, awesome info!
Yeah boi best tutorial I have seen on building traps. Also you are better than some drummers ive seen live :(
Not only sounds great, It looks cool too !
excellent vid... simple and easy... and pretty effective.
through the mic / over youtube it was hard to hear any difference in the lower bass drum region - but the upper frequencies - and especially the cymbal decay... world of difference at the same volumn... literally night and day.
I suspect one might need 12" traps for base it would seem.
either way, excellent presentation. Thanks
I love your vids Mate!! Can I make a request for a video on what guitars sound with and without these? Keep up the good work, appreciate the great info you give us!
New to your channel... I dig this a lot. I'm going to look for other DIY videos on your channel, and gratefully request more. Please and thank you.
Cheers!
It really makes drum mixes easier. Thanks m8 :D
Awesome video! I would love to see more vids like this, it helps a lot our economy!
I recently had a chat with a mastering engineer from one of the big studios regarding the subject, he pointed out that priority is to avoid still standing waves.
Absorbers like those DIY ones are fine but they aren't bass traps, in addition it's adviced with some sort of diffusers to break some waves and reflect them back into the room into different directions, you don't want to muffle it all, and real bass traps might not even be needed, depends a lot on the room size and layout.
A tip for you guys who are building a DIY studio, you don't need measurement equipment to set everything in the right spots either, just talk loud against your walls and listen, the human voice is pretty efficient to figure out where to place traps, you can then add difusers in between and on the wall, shelf or what ever your studio monitors are facing behind your chair, equipment and other objects can also work as diffusers as long as they are soft enough.
It is also adviced with at least some thick dense fabric at the ceiling above the mixing area too, hard surfaces that can bounce soundwaves parallel between eachother are always the worst.
Yes... These would be better named broadband absorbers. I made some of my own using plywood frames, Roxul Rockboard (similar to Owens Corning 703, but cheaper), and microsuede cloth (materials from ATS Acoustics). Just three 2x4' x4" absorbers made a HUGE difference in the sound of my room! The bass from my monitor sub tightened up considerably. More absorbers are needed; I just need to get around to making them!
@@soundman1402 Try with layers of cheap towels in the frame, can be as and even more effective as those solutions labeled with flashy words as acoustic, pro, studio etc.
Awesome!!! Thank you Glenn!!
Thanks so much for the video and the great idea. As a rookie I cannot hear much of a difference but I think as I grow I will come to have more of and ear for that.
No man ... I've been building houses and other things ,,, all my life and that's a genius design ... it's cheap ,,, quick and easy ... I've been looking at different builds and solutions to this problem for a while ,,, and you've covered all the important basics ,,, well done 👍👍👍 thanks man ...
Man every time I tried to come up with the build I always overdid it and it just wasn't reasonable to do ,,, whatever you may lack in building experience only allowed you to come up with a solution outside the box man this is really good thanks a lot
He looks so awkward playing drums, it's hysterical xD 😂
Wicked cool vid, thanks guys
I work for an Insulation company here in Arizona, duct lining insulation will work just as well. It is compressed like normal sound barrier insulation, down side is it comes in a big roll fairly easy to cut though. FSK lined batts will be a bit tougher to cut because of the foil. just my two cents.
703 board is made for duct lining, really none of these insulation products were designed for acoustics until they figure out they can jack the price.
Damn! The end result was a world of difference and thats because I am listening on my laptops meh speakers right now. For sure am gonna look into making a few of these guys
I also thought this was about capturing bass players in a secure location. This is like the advice we really need, but not the one we deserve!
Wow those really tighten up that kick drum. and for $40 really affordable, thanks for the great DIY tip man! :)
Hey, this is a cool vid! Thanks for posting!
Nice. I build some a while back using 1x4 lumber with a 1/4 inch plywood back and only one 2 inch fiberglass panel. The back panel was recessed one inch to give the space. Much heavier. I may redo mine with the metal studs. I have two six foot tall panels hinged together to for a singer and the screws have pulled out because of the weight. Metal studs would definitely improve the setup.
You're a savior. I was going to blow most of my money to sound proof, but this is far better. THANK YOU!!!
The rigid fiberglass is sold at HVAC distributors and is called ductboard. It is available in 1", 2" and 4" thickness (the 4" is generally special order.) It comes in 4' x 10' sheets. If you special order the thick stuff, you will have to buy the whole case of 3 or 4 sheets usually.
Hey Glenn!
First: Thanks for your great videos. Both hilarious and educational.
I've been browsing around your videos for recording tips, what I haven't found yet is tips on recording without making too much or any noise.
I'm thinking about starting to record my jam sessions. I play guitars and drums.
Since I moved to my apartment I've been unable to use a guitar amp out of respect for my neighbors. I would therefore LOVE your take/opinion on what one can do to achieve a (nearly) silent studio. And I bet I'm not the only one.
I'm assuming that you need a somewhat loud amp for some punch and to ensure that no other noise goes into the mic while recording.
First solution that comes to my mind first using a Line6 POD or Fractal Axe for bass & guitar, a set of digital drums and vocal mic, all into a small mixer, like 8 channels or so, and computer software for recording, you´ve already shown us that in one of your videos.
The idea is to use headphone or in ear monitors while recording, and studio monitors for editing the mix.
So tips on the things above would be much appreciated.
also: I'm from Stockholm, in my mid 20's with a decent job and decent pay but as I am kind of new to this I'd like to begin with affordable stuff before upgrading.
Thank you for your time and videos!
Great video, Glenn! Just wondering if the aluminium frame actually serves a purpose for the sound absorbation? Or are they just to keep the materials in place?
The aluminum foil or frame around these insulating materials helps maintain their shape and structure, preventing the materials from sagging or shifting over time. It also provides a clean and durable surface that allows for easier installation and handling. Additionally, the foil can serve as a barrier against moisture, protecting the insulating material from potential damage.
Wow the difference is very obvious, thanks for sharing.
Who is this polite man and why is he not yelling at me?
In all seriousness, I am building a garden office which I want to put a drum kit and my amps into so I've been double checking these videos (egg carton soundproofing being the other one).
I am planning on soundproofing with rockwool in between the walls/frame floor and ceiling. Then acoustic plasterboard on top of this but I am not sure if I should go for a double layer of acoustic plasterboard or not. Feels like something I'd regret later down the line and I really don't want to disturb my neighbours.
Anyway this was very helpful and informative and it's really cool to see how much you have progressed in your presenting style as when you're watching regularly (like I do) you don't notice it as much.
Keep up the good work and praise Krom.
Wow, impressive!
cheers
JB
Wow great work thanks for the tip
I love this video. Great idea and great advice. I'm wondering if you might do a video on Standing Waves and why acoustic treatment is needed in the first place, for all the noobs and amateurs?
Rock on bro! \m/
I’d love to measure what frequency range these are affecting. I have a suspicion these alone are probably working more at high and midrange without a tuned mass to dampen. It’s possible the plasterboard behind them is acting as that mass and it’s possible the membrane foil is doing it but I don’t think it would. Anyway food for thought. Genius going with the steel stud stuff. Probably ends up much lighter than my wooden frames. Really good to see someone putting this content out there, thanks for that.
Sold, awesome toot-orial! Tanks!
Amazing sound difference. And as far as your drumming is concerned, you are the bass player of drums! :-D
When I first started playing bass, I was playing in the worship band at our church doing mostly Hllsongs type stuff. I wasn't very good yet, but being an ex-hi-fi salesman, I was a gearhead and used an Acme Low B2. The guitar player used a stack of two peavey 4x12's and a 200 watt head with digital effects. He would give us amazing tapes of his home shredding, but all he could do in front of a crowd was strum chords. Oh, and It was a constant point of contention between us that he had too much bass dialed into his sound. It was "friendly" but only because I was so new to the bass that I didn't have a lot of confidence in my position. But that changed over time.
And the standing waves in the place caused the bass to be overwhelming where the mixer was located.
Anyway, in rehearsal they constantly complained that my bass was too loud and yet I had a hard time hearing myself. So one day it came to a head.
They complained. I turned down. They complained. I turned down some more. Finally, they complained, and I turned it OFF, but kept playing. They stopped the song and complained again. There was a very uncomfortable silence after I explained what I had done.
It's affected my attitude toward guitarists ever since. I'm gunning for it. We each need our own space in the mix.
But I'm gonna give those traps a try, both for my home system and the club at which we are regulars.
Thanks for the idea! I know these kind of videos may be a little less "profitable" than others in terms of viewers, but as it is more technical, are deeply appreciated by people building home studios, myself included. Cheers! PS: I have to ask, and sorry if you already mentioned in another video, what's the name of the SMG opening song? it's totally badass and would love to listen to it if it were a band's song instead of a specific "jingle".
That was so cool!
If you glue the two fiberglass sheets together with a small bead of construction adhesive it will create a small air gap which will improve the soundproofing. It is a small detail but makes a big difference.
Nice one man!
Nice job, Glen!
awesome,thank you good sir!
use a few lengths of suspension strapping ( comes in a big roll ) and then use short self tapping screws to attach it length ways.. this stiffens up the edge. You can now hang them horizontally if you like for under $10 a box a strapping should do several. as will a box of short screws. OR if you have more metal studs you could just double the side you are going to hang it by. :) these are great traps, much needed in our new place with wood floors and rounded wall to celing transitions ( older style plaster arches. ) thanks Glen :)
great advice. Ill be making my own with rockwool!
Nice Things! Thx for that video!
Strictly speaking these aren't "Bass Traps" they are broadband absorbers and wont do much for bass they will tame the high/mid range and early reflections though.
For bass you need a lot more depth, just thing about the mathematical size of the sound wave you are trying to "absorb" menu bass waves are bigger than small rooms entirely so there's nothing you can do to catch them, which is one reason why bass often sounds more apparent outside of the room rather than inside (the room is just too small).
You will make a great improvement if you space your absorbers a few inches away from the all because the wave goes though the trap bounces off the wall and returns through the trap, the airgap between the trap and wall improves the traps efficiency at this.
If they are mounted dead against the wall on hooks the effect it lessened and less efficient.
The best proper "Bass Traps" to make are corner traps and are very deep (as described above) the deeper the better, often called superchunks and worth googling to see what im talking about.
- Not trollin just thought you might find this useful info.
Also the alu foil backing will have a reflective effect on the HF/HM so depending on the frequencies you are trying to deal with this may or may not be an advantage/problem.
The difference between these placed in a corner and a superchunk type trap is quite minimal. I did my homework on these. Read a few charts.... superchunk is better, but not by much. And watch the whole video... I mentioned using spacers. But listen to the bottom end on the kick in the a/b clip. That's evidence they're doing their job.
Stacked the way they are, if they reflect anything, it would be absorbed again by the insulation. If I had the foil facing out, you might have a point.
SpectreSoundStudios superchunks done properly have way more low end absorption due to their depth again you need to consider wavelength, you need depth of absorption not just a panel a couple of inches deep and im not denying them doing their job nor trolling i'm just trying to help give you some long standing tried and tested fundamentals that are proven.
Neil Hester and likewise with the foil, you have barely any depth to absorb anything but HF waves before hitting that foil.
They key to all of this is wavelength of the frequency you are trying to tame and the size of your room, throwing up some broadband absorbers will instantly make a difference in deadening your room, if thats what you want then great but if you want to balance out the frequency response of your room (you especially need to in a mix room or you wont be hearing your speakers correctly and probably make the wrong decisions when mixing) then you need to first measure your room with an RTA and measurement mic to find your problem frequencies and then treat them accordingly with tuned traps to match.
Thanks. This really opened a new inexpensive solution
I'm obsessed with the added use of rubber on the back side. Sound would then travel through the Owens Corning 703, through the rubber (layered rubber of 1/2") adding mass. Sound would then bounce off the wall, and what remains would then travel back through the 1" rubber, and then through the Owens Corning 703. The key to knocking out low frequencies is the weight of the entire panel. 25Lb panels is good, but 75Lb panels is even better. The rubber mats possibly from rubber entry mats. If you can't get rubber entry mats? I do believe tires are shredded into small pieces and used for various things, so if you can get some of this shredded rubber, placing that into a cavity 4" thick, and MDF board on front and back would knock out low frequencies.
great channel format, nice clean and simple easy trap method. i appreciate your vid and i would like to add a suggestion to make this design a bit sturdier... instead of back-angling the cuts where the stud folds, you should straight cut them (or back-cut them just enough to get them to fold over one another), and leave enough overlap between them to add a rivet to each corner as you did on the "top." this way, all 4 corners will be "locked" into one another, increasing the overall sturdiness of the frame at the mere cost of a few extra rivets.
what do you think?
in any case, thanks for the vid, great job.
Awesome. This was the next thing I needed to figure out and I can't buy any more big ticket items for a while.
If any of you guys don’t want to risk messing with the Insulation or is difficult to get it, layering bath towels is a great alternative. I build a vocal booth with traps made out of towels and it works really really well.
Nice Derek Hess poster and a very informative vid. Thanks
You've got a good start. For increased BASS trapping effectiveness, you'd do better to orient the foil side facing into the room. Remove the foil from the 2nd sheet, or buy non-FSK (unfaced) panels, and place it behind the faced sheet. Make sure the foil is facing into the room (away from the wall). You will notice some mid-hi reflection back into the room, sure, but the increased bass absorption is worth it. (For panels at first reflection points, use non-faced.) Place the trap diagonally across the corners, floor to ceiling (as you mentioned), and you can also suspend them horizontally at the same diagonal/spanning position, where the walls and ceiling meet. You mentioned a space of 1 or 2" behind wall panels, but a minimum of 4" is widely recommended. It's the equivalent of increasing the depth of the absorber. (roughly speaking). Some folks recommend using the heavier oc705 for traps/absorbers, but 4" of 703 and 705 are roughly the same. 2" of 703 will absorb more mids, 2" of 705 more low mids. All traps benefit from distance from the wall. For really economically and beefy bass traps, check out the concept nicknamed "superchunks" using the pink fluffy insulation. If you can give up the floor space, 9"-14" (thereabouts) of pink fluffy (non-compressed!) in some simple frames across front-rear walls, floor to ceiling, has a dramatic affect on low end - real low end, not just the basic low mids you can grab with panels - we're talking down in the notorious 60 hz range. Cubic ft-wise, it's very cost effective. Hit me up at SnellingAcoustics (dotcom) and I'll gladly share info.
Nice Job!
