Generator Noise Reduction Box DIY (Styrofoam)

Nice job on the video. Thanks for the info.

Fail. 1 db for what?

What type of construction foam is that exactly?

Weird that it got louder

Is there any heat-related issues if you use the foam? I’ve got an rv box that I’m doing…

My only concern would be air circulation to keep it cool. Also, wouldn't venting straight up be quieter than straight out where it can echo off things?

Based from testing, it seems it did not work? Higher db with soundbox?

So during the last hurricane I made a box for my generator and what I realized is if you close off everything it'll just echo inside the box like you put your phone into a cup. If you can aim it like there's a school behind me so literally no one lives behind me. I made a triangle with the box and shot it towards the school lid and all we couldn't even hear it. It's a 5500 watt generator not an inverter and inside my house 30 ft from the glass door I couldn't even hear

I got the same welding mask!!

Good stream!!!

Your going to overheat that generator.

The generator and engine are air cooled. Enclosing the generator will trap heat generated by the engine which raises the enclosure temperature. It is important to measure the temperature rise inside the enclosure to prevent overheating. The size of the cooling fans are critical for this application. Usually the generator specification will state the maximum operating temperature. The Honda generator I have states maximum operating temperature is 40 C or 107F. So the enclosure temperature should not exceed this. Remember the more load the more heat that is given off so a test of the temperature rise should be at full load. A good item to get is an inexpensive indoor/outdoor thermometer and put the outdoor thermometer inside the enclosure. Then you can get a continuous reading of the enclosure temperature.

What size and generator are yall running im having to look into oone to run my 5th wheel on back 40. So this video helps alot with builing the box

great attempt … but it will overhear terrible in the summer
you need to have the exhaust pipe out of the box and a big fan to pull all the hot air out
I have 4 fans like yours and it still overheats in 90 degrees

how does the fan work or power?

dense materials like concrete do a better job absorbing sounds. Even a few layers thick of drywall would blow this foam out of the water. Foam is not a good choice if you are going for quiet and no so concerned about portability being lightweight. Doing foam then drywall then foam then drywall would be ideal

Con - needs fuel to run the exhaust fan.

Well do you recommend styrofoam to kill the noisy pump??

if you want to quiet them add more MUFFLER! thick pipe! theyhave SHYT for mufllers, nothing, a little steel wool, add a car muffler its as quiet of not quieter than your car, be sure to ceramic coat for heat dispersion, so quiet you cant tell if its running .. then insulation, be careful of overheating in these boxes tho, they are air cooled, fans?

What material beats all these five different materials, is any of you experienced it ? I'm a contractor and a homeowner asked me to build a sound proof cover for his entire pool equipments a room but I'm still worried to accept the job, since if he isn't satisfied with the noise, I will lose the cost for the entire material, which is estimated $450,-

There is no difference because it is light; there is no dampening and holes with no 90° where sound escapes.

So much vibration, I was hopin he used those Foam pieces that the use in literal… Sound proofing rooms for music, etc. Light Exterior weight, with interior with that interior material.

Can you update your styrofoam with mlv?

When we used foam like this on the job we just used a table saw for the cuts before we went to the job site. It seems like a lot of extra work making all those things when one piece of equipment can do the job of all of them.

Thanks!

Generator can overheat

Me encantó, lo felicito, entendí todo y hablo solo español... gracias 😊

I may have missed it but did you build yours for a specific gap between your generator to box? Would the sound be louder or quieter by building the box larger?

Ótimo, muito obrigado pela ideia 💡

"the con " is the generator it need ventilation from heat specially if going to run for long period of time in a black out.

I’m not sure what you do for a living, but you missed your calling if you are not in the media in some fashion! Great voice and delivery! Thanks for the box video!

would it make a difference if i built this exact box in 3/4 Water resistant MDF?? would it be better?

is'nt that an air cooled engine?

line it with amazon sound deadning and it would probably cut the sound in half

Question what is to stop a strong wind from just blowing the box off the generator and lets not sell yourself short this could also be used to protect the generator in bad storms thats when you really need benerator when power goes out so lets protect the styrafoam how about rino liner sprayed on outside ideas?

One backfire and you have a serious fire problem.

If you bury the electric generator 33% to 66% and 100% below ground with a styrofoam cover on top, will this setup make any significant difference??

Try using Sonopan on your next build would love to see your results

We use to put a dog house over our generator but it would finally overheat and power would slowly go down. We'd run outside and flip the top off so it could breathe and it would Rev right back up. Ours was wood. A real dog house, with a good sized door.

That is already a really quiet generator. Not sure why this was necessary.

You did the test with an already quiet generator.

I would think a sound box made of much denser material would work far better. And i think the smooth foil interior would just reflect sound, no? Also, the boxes I've seen have multiple push and pull fans to keep serious air flow going through there. My generator (Winco 6000 open-frame) is pretty darn loud but the manual specifically says to leave it in the open air and not do anything that would compromise air flow. It is surely an annoyance to the neighbors but fortunately is hardly ever needed.

not really worth it

Gotta love the radio sportscaster voice! And the enclosure is inspired. Nicely done.

Am I right that at full throttle with the box the generator produces more noise (64.5 dB) than without the box (62 dB)?

This channel saved me $1500 for the zoombie generator box they are selling. I make a better version of it by adding a exhaust muffler sound reduction and added sound damp foam inside of the box, the sound from generator is now reduced almost by half. Subbed and likes. Thank you

Engine killers over heat no airflow .tell the manufacturer the idea and see if you get warranty 😂

okay what if you double it? would it be whisper quiet?
