Generator Noise Reduction Shed $30 Design

[@MrFredsDIY]

So what are you guys think? Is this box worth the effort? Let me know your thoughts. ▶️Here is my newest generator sound box design kzbin.info/www/bejne/jZ_CeHlnh7aipdksi=3QVhW5V_QWGCH1Pn

[@-.__.__.-Rad]

No, it does not work - it just looks good. I typically never use a gen in the nice conditions you had... I want to see the test in a storm, 60mph wind gusts, for about 6hrs. Let me know if the box is still there and if the generator is still cool to operate..

[@jacobdominguez8221]

@@MrFredsDIY you have a small generator. I’ve tried this before and my generator nearly burned the engine. It overheated. Your oil will break down fast and need of changing it often. You need good ventilation or a fan inside. My generator is twice the size of yours and was advised not to do it without an internal fan for airflow. Good design though.

[@MrFredsDIY]

Thanks for commenting! What size is your generator? We did a pretty thorough testing video with a thermometer in the oil and the temperature ran normal.

Where did you get the material that you did the build with, the r-tech premium engineered insulation that is.

[@jaredkerstetter8875]

Small tip from my experience. Make sure not only the engine can breathe but the generator also needs to breathe. I learned the hard way.

[@catbird1759]

When we sat up generators years ago in the military, we used sand bags, the sound barrier should be built like the letter "G" and the top open. The opening should be facing towards any breeze that might be available. The sides should be slightly taller than the generator. This emits noise upward which makes it quieter. Heat is death for generators. If the generator doesn't have a sound barrier built around it, it is because it needs air. Just simply placing a barrier between you and the generator will cut the noise quite a bit. The materials that you used are excellent.

[@douglass56]

I see it now. ISIS stumbled into your camp because it was so quiet. They didn't know you were there. 👍 Good info by the way.

I dig your design. I built one almost exactly like yours. Being in broadcasting all my life I have heard what a difference sound-deading material can make. I lined the inside of mine with a product called sonex sound dampening panels used in radio station control studios. I had saved a bunch of scrap Sonex from a studio build. I had no idea at the time what I would use it for. glad I did. It works extremely well to dampen my RV generator. The only problem I ran into was the CO detector on the generator was very sensitive and would kill the engine if the wind was just right. I did a little tweaking with the box installing a small fan. Flat surfaces reflect sound in a big way. The Sonex (with a massive surface area) absorbs it like crazy. Thanks for sharing & Cheers from Louisiana.

Yeah it is an issue, My friend made one of these last summer used it on one of the hottest days of the summer to run his AC for an hour and it got so hot it swelled the gas tank and over heated the motor. Once it all cooled down he tried a box fan and it still was getting too hot and it really didnt help with sound all that much, he just ended up getting a much quieter inverter generator.

I designed a double shell for my upright compressor out of 3/8 plywood. It's the same shell design as yours, only vertical. But mine has another larger shell covering the open side, leaving a 3 inch c-shaped opening opposite the smaller shell's opening. Inside the larger shell is a lining of old carpeting to absorb sound. It works well and the compressor stays cool. The only drawback for using it around a generator is that the genset needs an exhaust opening, which lets out noise as well as exhaust.

[@kcgunesq]

If I tracked your numbers, the difference was generally about 2-3db reduction. While most people will be able to hear a difference of 3db, it is very near the limit of discernment for most. No one will consider a dramatic reduction. Still, i love the effort and plan on watching your earlier versions.

[@nbookie]

A couple comments from my experience living on generators 24/7 for years. Lift the sound deflector an .5 to 1 inch off the ground to allow cool in hot out the top. Will not change your sound. Line the inside with carpet or welding cloth or "bag of rags". 100% coverage not required. Run a flexable exhaust line as far from camp as possible (up high in a tree or along the ground). Moving exhaust (and intake if possible) makes a HUGE difference. On some units it more than the sound box.

[@jmcmahon1931]

adding a slight angle to the walls so the sound bounces down into the earth will help reduce the sound, you could also add in triangle sheaths onto the walls with your left over wastage, this will absorb more sound than just having flat walls.

How about just two 3'x3' sheets of 1\4 plywood, hinged at the top and the interior covered with sound deadening material, like a pup tent. Sound would still exit the ends but so would the heat and it would fold flat and provide some weather protection. Thanks for sharing.

[@RandomStuff-zt6qf]

[@henkholdingastate]

Why do I never read about the best place for noise reduction and that is underground. However, you must pay attention to air supply and exhaust and the exhaust can be connected to a long pipe. My father had this with a generator and you had to do your best to hear something in the distance. Note: if you have a high groundwater level, I would not do this. It is possible, but it may be too complex

[@kevinreist7718]

Most newer generators have a Carbon Monoxide detection feature that shuts down the generator if Carbon Monoxide builds up, such as running it indoors. You may need to ventilate this "enclosure" to defeat this automated shut down feature.

[@debohannan4315]

Sir that foam board has a sound reflective coating , seams like if you wanted to reduce sound you might try something that absorbs it instead of redirecting it like fiberglass insulation or rock wool , heck that fiberglass insulation board used for air condition ducks would be a better choice with the aluminum foil on the outside But you are on the right track.

It sat out on the desert for 5 days...making a ton of noise..and it saved that trip. Took it 200 yards away and leaned a camp table against it as a sound wall. Still have it. 50 plus years old now. Still fires first pull. And is noisy as hell. But we still count on it. (7 horse Tecumseh engine.) Bullettproof!!!

Dear Sir, I learned how to soundproof generator sets for the film industry. Your soundproof design is what I call, flat plane muffling. I built a generator, (120 kiloWatts, thats a turbo charged Cummins 6ctg, if I remember corrct), Mounted on a brand new truck, spankin' from the showroom, that on its first movie, was boomed up the side, by the fussy sound guys, microphone 3 feet away from the skin, with sensitive dialogue as they walked. The movie was Grampire, I don't know the local name to you but it was with Al Lewis as the Vampire. Al Lewis, such a cool guy, not that I'm insinuating a closeness. One day he talked about the car crash on car 54 with Fred Gwynne. That's all. I had always had an image of his credit on The Munsters. That crooked swerve of a signature. I got to work on a movie with him. He was the Best. Al Lewis is cool.

[@-.__.__.-Rad]

This looks great when tested for 15min in a nice day.... Now picture the grid power is out, 60mph wind gusts 5-8 hrs of run time needed in the middle of the night.... I'd pick my 3/4 treated plywood box, with angled roof(shingles on top), reinforced with 4x4 in corners, 2x6" duct fans for exhaust and 1x6" duct fan for intake(cold air). The box has soundproofing on the outside.. I can go to sleep, knowing the wind wont blow it, the gen will stay cool - that one was tested also:)

Throw a mover's cloth over it, or a sound proof cloth over it to dampen the sound ever more I think. Great video.

Suggestion: Layer the inside of the box with egg cartons or sound deadening foam. (I work in a recording studio - it's all about the acoustics...) Also, my Dad built one of these in the 70s and used egg cartons on the inside. Thanks for the video and how you assembled yours.

The 2 things that kill gasoline motors are heat and vibration. I used 2 10” 12v radiator fans pushing air across. I checked temperatures before and after and it was better than open air. Heat rises but I didn’t want to open the top so I blew it from once side out the other. Worked like a charm.

The box would be more of a upside down right angle trapezoid. All the sound would go up and dissipate vs going out. 🤔

[@emolasher]

I wonder how much a simple large cardboard moving box would compare, maybe even just set it down in a large box to see any difference. Other things to try could be set the generator up in a bowl with 45 degree angled sides so noise is reflected up. Heat would rise easily too.

[@kittywilhite9583]

I'm not worried about sound since I only use my generator for a minute or two at a time. But I am wondering if this design would work for easy on off protection from the elements if I add a 4th wall and a pallet underneath. Like being under a giant cheap cooler.

Betting the fully enclosed foam box with the exhaust fan will win in all categories. Military used to put their 3.5kw set in a dug out hole at least a foot below surface. A pain to get on generator detail.all the noise and heat went straight up. Best that could be done in a tactical fld back in 80s. Been considering one of the kiddie tents. Cut out bottom. All of them are free standing with flex poles doing from corner to corner. Mostly interested in keeping out of rain. Have the genset on pavers plop the tent over it stake the 4 corners. And stores in a roll next to generator. Can see a need for the box though in camping ground situations.

[@leehyer4916]

I was thinking go over the outside with plywood, put a hole in the back with a fan and put a couple smaller holes in the front so the air can flow Also, maybe put like a vent cover over the two holes maybe make the plywood box a little bit bigger and then you could have the vent holes not in line so it kinda keeps the sound in that way does it make sense?

get a small car muffler and engineer a quick disconnect on your genset with flexible exhaust pipe to the muffler. you seem to be mechanically inclined so it shouldn't be a big deal. it will be much quieter and take up less room. i've done this with an 11hp kohler cast iron engine on a homebrew log splitter and it is unbelievably quiet

[@davidc6897]

The only potential issue I see is with the generator overheating since it is air cooled. You may be able to further reduce the sound with egg crate or other wool sound proofing inside the shed (would need to make it large to accomodate), or you can drape a heavy wool blanket over the top to further muffle the sound? Good luck on your quest and thanks for sharing. You already tackled some of the problem with generators with buying an inverter type that is probably 20-30 Dbs quieter than a standard generator.

@@MrFredsDIY if you try MLV, make sure to get the fire rated kind with foil on one side.

What do you do about overheating the generator because it's not getting enough air to cool

[@MrFredsDIY]

I don’t know, it’s never happened with my setup. In testing it didn’t get hot. kzbin.info/www/bejne/iqqbkn1oes2Sjassi=zmLVi800gw17RstJ

How about just adding a exhaust muffler?

The end of the video sums up my life at this point. Retake....sigh....retake hahahaha

[@stephenbrown2054]

Generator manuals say to keep 3 ft on every side. Doesn't this risk overheating or melting?

[@badgorilla]

Wait, you read them all? In other comments, he said he did a heat testing video.

[@dkat1108]

Good idea but there air cooled and this almost cuts any circulation off they in freezing winter probably ok but in 80+ degrees I might want to put a opening on the other end and maybe even a small fan...

[@MrFredsDIY]

My latest design has a few of the features that you mentioned. Thanks for commenting! kzbin.info/www/bejne/jZ_CeHlnh7aipdksi=DPaKRWx1tvagn57P

Good morning, what DB meter app did you use?

[@MrFredsDIY]

I use the “Decibel X” app

[@josephsilverio9047]

Thank you

What did you line the inside of the box? It looks to be some sort of aluminum or steel sheets. Lining the inside would cut the sound a bit, but it will resist the heat of the generator, without it it may melt the Styrofoam. This is a great video! Thanks for taking the time to make it!

[@MrFredsDIY]

That is just a foil backer layer on the styrofoam. I am working on a new video with a slight change in design and with soundproofing! That should be coming soon, thanks for watching!
