My compressor gets quieter and quieter the older I get.
What was that? Could you speak up please?
As someone that has something similar, you NEED a indicator light by your light switches to tell you when they are on. Otherwise you’ll leave them turned on accidentally all the time.
Or plug them into wifi plugs and then you can turn them on or off with your phone
UA-cam: In this episode, Jeff builds a huge speaker box with baffles at the back of his shed.
Jeff, very good of you to build such a nice abode for all the local wildlife. Wish our neighbours were as considerate as you, I'd have more peace in my life.
Stay safe Jeff! I know you’re a professional but I see some fires getting closer to you. Thinking of you guys. 🙏🏻❤️🇦🇺
I have some experience with 3D- printers, and they can transmit a huge amount of vibrations to the entire house when just sat on a table. An extremely effective vibration dampening method I've recently come across is to stack the printer on top of something heavy, I used an inch thick concrete slab tile thing, and set that on top of a thick piece of insulation foam. The slab absorbs most of the vibration, while the foam allows it to move a bit to dissapate the vibration while insulating it all from the surface undreneath. You wouldn't believe how much of a difference it makes. Anyways, great work as always! Just don't forget to drain the compressors, out of sight, out of mind or something like that.
Nice job, Jeff. When I finished my basement, I added a sound proof room for playing my drums. The solution was to use two layers of drywall with a 1 inch air gap between them (z channel). This was very effective. Maybe you should add an additional external layer to the box with an air gap between the layers? Otherwise, good solution for space and sound abatement. 👍🇺🇸
Hi Jeff! Here some suggestions:
- pay attention to source first and reduce the noise over there first - put the compressors on absorbers, install silencer on the intake, maybe check if installation of silent blocks between tank and compressors is possible.
- increase the weight of your box - put some sand bags or concrete plates. Wood is not enough. In order to reduce the signal you need to have weight.
- seal all the edges.
I’m dealing with the noise and vibration topic professional, so let me know if you need more advice.
thans Piotr
How about some isolating feet for the compressors so they dont transmit vibration into your box. Keep up the great work.
exactly, the weight of each unit transfers the vibration and sound directly to the frame.
I thought you'd want to transmit vibrations into your box?
If it doesn't work out Jeff build a chicken coop at the back of his🐔🐔🐔
you put it in some sand
@Paul J - Would a horizontal air compressor need sound reducing "shoes"? Or something similar? (I'm familiar with VERY basic building stuff but my hubby has said that I'm NEVER to build my own shelves again.... (Oh, come on, they never failed! They were just VERY UGLY!! I use whatever materials already fit the space I'm using since he doesn't want me using his circular saw....🤷♀️🤷♀️))
Bear with me here:
I'm looking to build a new wall in the garage for a finished, permanent room to sell Ebay items (or maybe turn into a nursery someday? Keep that in mind....). On the other side of this wall is where a car will be parked.
I'm looking to hide his giant, horizontal air compressor, his mini air tank, the accessories & interchangeable pieces, and several different hoses, and some hoses MIGHT be retractable now that I've discovered that's an option. The next compartment is his mid-sized air compressor (that he recently said is actually broken??😯🤔🤔), and generator. I may include his welding thing, err, um, machine, in my plans. Plus any other large shop tool I've forgotten to mention atm. Like a shop-vac??
Basically, I'm designing a garage/ shop/multi-purpose room with multiple access points that helps hide his giant shop tools while I have my own room for business purposes.
I need to know what kind of of air flow the air compressor would need GRANTED he leaves it in it's new "home" rather than dragging it outside to use it each time. Does that really matter? He mostly uses it to add air pressure to tires but I think, pretty soon, we're going to be needing it to work on a truck that's been parked for about 6 years. Don't even ask what the truck needs.... lots of different stuff - new gas tanks, freeze plug, fuel lines...
Well done. When I was grade 5-grade grade-12, I worked 1.0-1.5 hours a day after school at my parent’s automotive repair shop. Mostly cleaning/sweeping/prepping/lifting/stocking/garbaging/parts-pickup/parts-exchange/recycling (auto batteries and metal separation)...
Anyways, I to this day, am no hero, I always knew that the 35 gallon tank shop compressor was sooo loud. Man, I wish I had a few $ back then to contribute to assist my parent’s shop back then.
Sorry for my memory rant.
Oz 🇦🇺 bud... Canada 🇨🇦... with you
Jeff, Designer & builder here who also used to do trade hifi gear & do sound system installs into bars & restaurants (another life). Density (weight) of material is where it's at. That foam will absorb and change high end resonance somewhat but not really the volume. Easiest, cheapest and most effective mod would be to line the ply panels with gib including the base. They're effectively acting like drum skins at the mo. I'd go double layer of gib then carpet offcuts it's so cheap and easy & heavy.
I tried to do this to my compressor and it didn't work. So I sold it and bought a quiet one.
If you sell both you can buy one bigger quiet one and all the noise and space problems go away. Enjoying the build. Keep up the good work.
To me, that whole area behind the shed looks like the perfect place for a paint mixing and storage room with a door straight out of the back of the booth, and the compressor cupboard could make the perfect bench for doing the mixing on.
We put petrol generators down a hole when camping and it makes a ton of difference. And it would be cooler. Just need a lid to keep the bugs and dirt out with a similar baffle to what you have now for airflow.
Hi mate , great video! I don’t know if someone has mentioned it (and I know it’s not something you require, but may help others) but where you pinned the sound barrier I would have used a heavy duty adhesive like gorilla glue , and dab a few spots of T rex in the corners to ensure all points are in contact with the substrate .it was a learning curve for me too dw, I built a soundproof rehearsal booth. Ran snake ducting like you did. Instead of marine ply others could use eps panel (same material for commercial freezers) has wonderful insulation and great for sound deadening. 1200 x 2400 sheet will cost you around $120. Then they could line the panels in the material as you did or use the cheap 24 packs of 30x30 cm soundproofing foam and overlap each end. If you have a small compressor, you could recycle an old fridge or freezer and already have a box to work with. I used green glue on my soundproof rehearsal booth it’s the best for sealing. Very expensive, so a cheaper alternative are fire rated sealant. They have excellent sound deadening properties. Keep up the good work!
Jeff mate, get a 15A outlet in there and buy a single bigger compressor to replace those Supercheap Auto shitboxes. That will cut the noise in half. Got my Peerless 15A unit second hand for $500 and it pumps more air than both those machines combined. Thanks for all the videos :)
Maybe a finer mesh screen, I can only imagine the crazy snakes you guys have over there slipping inside of that nice warm place for the
Thank you for posting! Great practical guide and an idea for me so I can get the compressor out of my garage while I'm using it (mine is annoyingly loud). Using 3/4 inch CDX as your shell, covered in some waterproofing (deck) finish, along with the same sound absorbing foam would have nearly silenced your compressors. CDX is about 3-5x as heavy as the marine laminate that you used. Just a thought.
I like the baffle idea! To get better sound deadening you need mass. I have a recording studio and those Foam Pads are great for high frequencies and killing any flutter echo. Mass could be anything from solid concrete to dense compacted insulation! Nice work :)
Different density materials help so get some heavy rubber to line it on top of the sound deadening material or just add lots of rockwool under the roof and an extra set of baffles.
The snakes of Bowral thank you for such a wonderful warm new home. Lol. Good job mate.
Your neighbor will love it, lol..
Foam helps with sound absorption, meaning that it will be less noisy inside the box. What you are looking for is sound blocking, meaning preventing the noise from going out of the box. For that, I would use something heavy and dense as possible such as a concrete board. I would also to fill the gap between the doors as much a possible with foam. Here's a link that explains it all:
www.acousticalsurfaces.com/blog/soundproofing/soundproofing-vs-sound-absorbing
thanks that was helpful
For your neighbours - and you - just fit a simple time switch that turns off power to the compressors say between 8pm and 8am
I modified the intake to use a small air box assembly from a vw golf. This made a noticeable difference in the noise levels.
That sound deadner looked amazingly effective when the microphone didn't work. =D
It sounds wayyy quieter. Nice work. I'd put metal door screen on the side to keep bugs and mice out, though.
Jeff mate. You need some fans to draw air in to keep those compressors cool. Also, much of the noise of those things is the inlet. So putting a pipe on each inlet into an air box or muffler will also help.
Always an interesting conundrum silencing noisy compressors.
There are many thing's you could do Jeff.
1. Use you biggest compressor motor to fill both tanks for one. (Saves on power)
2. A large enclosed External Air filter plumbed to compressor head inlet side. ( like trucks use).
3. Moisture issues may as well cover that too, 😉🙂👍👍 on the exhaust side of compressor head there is a possibly alloy or copper line running to pressure valve on tank.
( valve has a small line to electric pressure relief valve, where red on off button is.
Re route the large compressed air line from head to front of compressor with aneeled copper tube make a coil out of about 4mtrs of tube, perhaps by wrapping around 100mm copper log or treated pine log as I call them. Re use original tube nuts flare pipe re fit, and the extra dwell time before entering tank will allow for heat transfer to copper tube. Less compression heat less moisture in air tank, longer tank life.
4. Bump the tank electric shut off pressure up to 110psi most are set at 95- 100psi.
The box well good idea now fine tune it close ends ,off add rubber floor matting or calk tiles to floor. Extra rigidity to doors should be really sweet.
As always take what you like and leave the rest 😉🙂👍👍
Nice. That netting is just small enough to keep the possums out … and let all the snakes and spiders in from that massive back garden. I’d be opening those doors carefully. 😂 😂 😂
Awesome 👍🏾 as I used to live in Australia that's alot of work in the heat but you did it 👍🏾👍🏾 and it's better for you to talk with good job 👍🏾🤙
If we consider that noise is vibrating air, then it is worth putting the compressors on thick anti-vibration material like rubber or laundry machine like legs. Keep up the great videos. Great channel !
Rigid insulation on the outside of the box would help a lot with the noise.
I built a box for my compressor like the one you built but added rigid insulation around the outside and put foam weather stripping around the doors
Also I installed furnace filters at the ends to help keep it cleaner inside and it reduced some of the noise as well. Love your videos keep up the good work
Don't forget to add remote drains for the compressors
made this comment on his Patreon. seen so many compressors killed by not being drained on the regular. and when you put them someplace you dont see them every day you forget to do it.
Why ??!! Look how small they are . I've never seen chain holding down a compressor .
Just checking in to make sure all is ok with you with the fires being so drastic? Stay safe
Sound proofing requires mass as well as airtight enclosures / baffles. In recording studios two layers of gyprock are typically used and then there are also damping glues used between those layers (eg green glue). It’s quite a job to really soundproof something.
The floor under the compressors might need more support. And perhaps some soft rubber mounts under the feet? Are they bolted down to the floor? How about building a floating base for them, suspended by springs from above?
I think you are right. That is where the bulk of the vibration is coming from
@@HomeBuiltByJeff it might be worth just packing the space between the ground and the bottom of the unit with dirt to stabilize the box and deaden vibrations a bit more. Maybe back the roof sheets with foam too. It's always worth keeping neighbors happy if you have noisy hobbies!
You need more mass in the walls of that enclosure really, and the doors have to be air tight. A couple more bends in the s bend could help too. Adding a mass loaded vinyl "shroud" inside around the compressors would help consideably I would expect. I'd also mount the compressors on a mechanically decoupled false floor inside the box.
Add timers or better smart plugs and then they you can turn them on and off automatically. Just make sure they are rated for the current.
That is a fantastic idea. I will do just that, thanks.
Nice Jeff. Best thing I ever did in my shop was moving the compressor. You will love it.
That's an awesome box. I think something similar can be built for an generator too. The baffles in the sides would let the exhaust fumes escape. But the box would start smelling horrible after long term use.
There is a huge problem with heat. Just by doing a basic paintjob an aircompressor stuck in a box without ventilation gets very very hot. Try to fix this problem, maybe use a fan.
And provide a fresh air intake for them.
Both ends are completely open so it gets plenty of air flow.
cotton towels have about 4 times the sound deadening ability than even the most expensive acoustic foam, and that's without accounting for the thickness... get down your local charity shop and load up on dirty old towels... 1" of towels is like 3ft of foam...
Brick or concrete would work great for silencing the compressors, but that would be a massive project. Great work Jeff.
Hi Jeff. Check out rock wool insulation. It is really pretty much the best sound absorption material you can get and its cheap and easy to handle. It'll do a way better job than the foam.
Nice work! At least your box blocked out most of the noise. I think a thicker plywood would quiet it a even more. Happy New Year! 🙂
Jeff check out some of the Chicago Hush compressors sold by Sydney Tools. Much quieter than the piston type compressors you have.
Best to kill noise is with bath towels. Buy them in the thrift store. Make frames 3 cm thick with the towels in them. put them at the back of your box, they don't have to be all the way around, they absorb the sound. You also have to place silencers on your air filter, which quickly saves 10Db.
Don't worry, mate.
I built a chook house but I'm not game enough to climb on the roof to screw on the ridge capping so it bangs in the wind. Been like a year now. Mice and spiders still love it!
Cool. Good idea mate.
Fantastic video and your timing is perfect. I am just about to do a similar thing for 1 compressor and a shop vac system on the back of my new Titan shed... I am going to lay a concrete slab and put rubber feet on them as per my newly installed aircon unit which seems to work well for vibration.
Keep up the awesome work (inspiration) and stay safe.
Regards,
Your number one fan in sunny Qld.
🇦🇺🇦🇺👍👍
You could try egg carton style sound absorber. Different styles but essentially it's a spikey irregularly shaped surface on one side n the mounting side is flat.
Some kind of vibration isolation for the compressor feet will help too.
Still way better than before.
I custom made an exhaust from a Vespa to quieten my large petrol driven compressor.
Great job . As you said the vibration will limit the effectiveness of the sound proofing.
Good job you can put the air compressors on some heavy rubber shock mounts to get rid of the vibrations .
And check them they do not get too hot and catch on fire 🔥🚒 maybe put a smoke detector.
It's good for what it is. But if you want them quieter, you'll need to work on the compressor supports... you'll need to add some dampers. If you just leave the compressors standing over the base of the box, the vibrations will come through. There's also a more advanced sound deadening foam with some sort of pyramidal pattern, that will increase the wall area, and introduce some new deflecting angles, that will probably help a bit...
If you have any left over from the 911 build, maybe an arch of mass loaded vinyl over the compressors inside the box might help? Being fully decoupled from the box should let it absorb noise quite well.
Thank you for getting me to do the same thing, I would like to be able to use my compressor a bit earlier and later in the day as well. Hope your township is save and sound.
Nice work! I like the partitioned ends. Perhaps a rubber floormat under the compressors as well as your sound proofing might help as the weight of the compressors would compress the sound proofing to zero. Filling in the sides under the box may help too.
Jeff My uncle had to soundproof a part of his flat and the stuff the neighbour who wanted this done supplied was like 2 sheets of rubber with what appeared to be carpet underlay between it and I can tell you it was tested by putting my compressor on it once it was laid and the neighbours wife couldn't hear it running. You and Mrs Jeff keep safe with the fires.
Basically the same principle I used on the 911.
@@HomeBuiltByJeff Correct, the neighbour worked in the music industry and that is where he came up with stuff used he did say that the stuff used in the sound booths was very similar.
Yes re carpet underlay. But it's hard to find the old style corrugated rubber stuff these days. That stuff weighs a ton. The modern recycled foam underlays are relatively light weight but they do a similar job to acoustic foam and can be free or dirt cheap from carpet layers (they throw out large offcuts & roll leftovers.)
jeff you are amazing just you building everything on your own i love it full respect tnx for the grait vidos
I am amazed you have the time with he fires going on right now to put out a video.
0:31 So true! I just started taking on bigger projects and I always think to myself, "gee it would be nice to have an air compressor"! So I did just that and I just finished installing my garage air system! I was originally going to build an enclosure similar to yours but to cut back on costs I decided I don't care how much noise it makes outside and I just want to keep the weather off of it. So I took an old refrigeration condensing unit enclosure and put my compressor in that around the back of my garage. Very industrial looking but it works perfectly! Great video and box design!
Anyways I came back to ask which song is that your using? I tried looking for it in the link to the site you left but I've had no luck.
Good idea, thanks.
Use plug timers makes it more controllable, Great video Jeff.
you tried your best mate. next time try thicker materials on both the boards and the foam. Also do a sound survey to check exactly where the loudest noise comes from. Mine from water pump was coming from the top part, these r the areas u will need toe nsure the thicker materials are put. Otherwise well done for the hard work
It’s a beauty
Rock wool insulation works the same -readily available from Bunnings plus it’s fire proof!
Couple of inches of concrete poured into that box to sit the compressors on perhaps?
Cool 3rd coz I waited till box half built😉🙂👍👍
Top Job as always Jeff
I need something like this for my air compressor, the main issue i have is its big and heavy so I don't know how I would move it outside into a box seeing as I can't even pick it up without an engine crane lol! Nice build!
They don’t sound so bad jeff you could here the car more just double up the ply jeff stay safe out there
P.s. Love the air intake idea.... They say copying someone is the highest form of compliments (well someone said something like that and I'm going to copy ya mate) 👍👍🇦🇺🇦🇺
Hi Jeff! I need something similar ,and wondered if you'd since improved the outside noise for neighbour happiness. Personally, i'm thinking of starting with double your thickness of foam. Cheers Nigel UK
Surely putting the compressor on a plywood floor instead of a concrete plinth was a mistake in the noise reduction process?
I need to do something like this for mine. I ha e a big 15 amp one and it's noisy. I think 1 think is to put some insulator under the compressor and also foam tape around the edge of the doors to seal them a bit better.
Great idea. Wish I had the time to do it!
Exactly what I've been meaning to do. Hope you've inspired me
You can ad a clock for the night time.
perhaps a better method would be to seal up both ends and fan air in thru a long insulated duct.
What if you used old car rubber seals all around the doors to block off more of the sound. And I wod highly suggest trying to isolate the direct vibration of the compressors to the wood with heavy rubber mats
You can add silencers on the air intake of each compressor. Your naibors will appreciate.
I think you still have space in there, maybe try to double up the foam it might lower the sound even further.
Definitely need some acoustic sealing tape for the gaps. You have lots of room to put more foam in. Old foam matreeses cut up and stuck on will still leave lots of air flow space.
Did you have any previous complaints from the neighbours? You are resto porn for me. After having a car resto business in oz, it kills me not having the space to do it here in indo. 😁. Thanks for the vids.
great job and clearly you thought it out, I don't want to sound like a internet expert but I would of put a top plate on also as I can see the ply warping crazy in the Bowral weather. ok maybe I should of not gotten so excited and waited till the end lol
The only way to really sound proof is room within a room concept you have the air baffles right
I like your video.
You have a decibel meter app on your phone? you could use it to see where sound is leaking out
Mate maybe have a look at a surge tank (also called a receiver tank) you can get some really big ones for not too much. If you interested check out Aussie Air Compressors.
What about the temperature inside that housing? I might be overthinking, but with the heat of the summer, insulating value of your sound deadening, and the restricted airflow around the compressors...have you considered them potentially overheating? 🤔
Idea 8/10
Quality of work 4/10
Expected result 5/10
hey Jeff can you please show how the compressors are joined together or are they running separately
Poor neighbours ...🤫
Hey Jeff, have you considered adapting a car oem airbox or a muffler to quiet down the compressors intake?
The intake is not noisy, and this box is far better ;)
Must be cooler down there. No way of even think of digging holes in the 8000 degrees we've had recently.
The ground was rock hard and dry, I am just stubborn ;)
How bout breathe holes under metal roof ?
Get a decent compressor, a Vane compressor that comes in its own soundproof box with a cooling system. All you are doing is transferring the noise outside, reducing the life of your compressor, making it harder to service your compressor.
Hi Jeff , did you coat the timber posts before setting them in place , otherwise they won't last long , termite meal time ...nice work though
They are H4 treated ;)
i like this
can you not just block the vents either side with the sound deadening stuff, it might still allow some flow through it?
No sound is escaping through the vents, it is coming through the walls of the box.
