Lake Michigan when she's in a good mood. Nice. Is that a BMW?

I can put on ear protection a whole lot cheaper. But we’ve got to build something to justify the stuff to the wife. 😅

Thanks. Best one on utube.

Oh I thought this was a silencer (suppressor) for a .22LR, so one could shoot in the garage or basement. I'm pretty sure it would be legal, too, because it's not portable and does not mount to any firearm. Then again....target shooting with Airsoft would be a better way to go.

Even with the door open it made a difference I think 4 latches is a bit of overkill.

best one i seen yet

Never gets old 😊 go tigers 🐅

What temp does the exit air get to. That would be my concern

Wow. Really nice. 50 pounds for the vac and the box together or just the box?

This was incredibly helpful

Joe! thanks for the inspiration. I just about completed my version of your build. It is super quiet and I appreciate your sharing this! Thanks so much

You did a good job on this. Did you add harmonics? Edit: I should have read the description. Nice work

I NEED THAT FOR DOING NAILS!!

Amazing work , I think I will test your build if I can ,

What about the. Won't get hot?

How about the temperature?

A horizontal baffle in the cabinet exhaust path would help create a drafting draw and lower the temperature by separating intake and outlet airflows, A PC fan could also force draft, quietly. Well done.

A 10 dB difference means the electric mower is half the sound pressure.

smart!!!

This video has a Tech Ingredients vibe.

Sir how can we build it??..

Not the sound difference I was expecting

Awesome..getting down to 66 from 87 is a great achievement...i am going to try out something similar to my inverted jigsaw and diy table saw...thanks for the video.👌❤

wow very impressive. i/m building mine on your prototype

You built a band pass box, but reversed?

I want one 👍

Great idea. thanks

Woodprix has a lot of plans to choose from.

Do you lose any suction by reducing the airflow like this?

Simply Fabulous!

Nice build. The absolute Best display of how effective it is. A continuous shot of the Vacuum running and being placed in the Cabinet leaves no question of the effectiveness.

can I have the reference of your acoustic insulation? i need the same thing, its really great.!.!.!.! thank you!

Wow and that VAC is superloud to start with. (Even more impressive). That is so very cool. I will build this! Jumping in truck quickly to go get plywood........run back in house and puts some pants on.

the silencers are not effective, because I used x2, two silencers, one at each mouth entrance and low from 77db to 69 db my rvk200 of 1080m3, some Spanish brand sonoconnect soundproof ducts lowered me to 70.5 db, using 70cm on each side, Well, the silenced duct has a value of 3.80 euros per meter, cheap but the silencer, the silencer duct in my case of 60cm and 200mm is worth 200mm is worth a minimum of 50 euros, for 60cm of silencer, which has 4cm of low absorbent material class, 25kg wool or other low density per kg per m2 and density at a thickness of 40 millimeters 4 cm of wool, the silencers are the biggest expense less performance, now disappointed with the result of the silencers that I buy confident in 20 to 28 Result db I will desistalare them and buy spending more than one for bad information and deception because they are useless, the change is noticeable 4%, a modern conduit of the latest design, it is French it is called phonic trap, I am sure that replacing my s traditional rock wool and aluminum sonoconnect ducts for this phonic fabric with cotton that is just as effective as wool plus the polyethylene layer will have better results than with silencers and the obsolete technology of traditional aluminum soundproof tubes plus rock wool plus aluminum Micro perforated, as I will trust the phonic trap brand, I found a virgin brand phonic trap from France that looks good, in my country Spain Madrid, we only have silencers that do not give good results and obsolete aluminum pipes plus rock wool Simple, thank God I found modern French ducts which I have not used or tested but I trust, my idea is to use my size of 20cm to which I am going to micro-perforate and the outer layer to add rock wool of construction of 40kg and 5cm more thick to add to the tube that thanks to the metal structures does not obstruct, then the 20cm tube has a total of 24 I stick 5cm good rock wool and have go 29cm I will add 1cm of acoustic membrane for low frequencies of 2mm and then a total of 30cm I will put another 31 cm conduit inside unmodified phonic trap, in plan an outer layer that protects, total a tube for a 200 extractor with a conduit of 315, but 115mm of absorbent layers

I think most of the noise comes from the motor and brushs inside it, I wished they would just make them less loud.

WOW on the sound decrease. That's quite striking...Peace

I like the idea, just wish there is some way to make it smaller. I have a 16 gallon shop vac

Dramatic much.

I built one exactly like yours and my original reading was around 80ish decibels and with the vacuum inside I get around 70 decibels. Yours is significantly quieter. Its actually silent. Mine has a pitch noise that just hurts your ears. I have no idea what I did differently because its literally the same thing in every way. Maybe the hinges are a tad bit different but that's it.

Impressed, yet disappointed that it wasn't actually reading -22dB.

What a gem of a video. You have made the world a better place. Thanks!

You should use Green Glue begins the foam. It will lower the noise to about 40.

Really handy for the stairs

If you want to go even further on noise reduction, remove the foam and apply a layer of MLV (Mass loaded Vynil), this is sold by sheets.

nice job, if you wanted to get fancy you could add a thermal temp controller that would automatically shut off at a preset temp

You really need to choose a shop vac that uses the vac airflow for cooling. Many do.

So my Fein Shop VAc is 66 dBa to start with, so I'm hoping that my cabinet will reduce down to below 50 dBa....will find out tomorrow. THANKS FOR THE IDEAS. Follow up: my Fein starts at 66dBa and is now in a 36”w x 36”h x 20”d.......very quiet. Cabinet and baffles are lined with a 1/4” heavy felt material. Also with a soft gasket Ed door seal. My only concern is the interior cabinet temperature that raises to 48C (118F). I may have to add a small exhaust venting fan and some inlet air vents. My filters are dead clean due to cyclone dust collector installed before vac.

Well done.

How long before it over heats and burns up the shop vac?

omg!
