5x quieter generator or compressor sound reduction quiet box 

I was able to purchase instructions for this Quiet Box. They are the most compete instructions you'll ever see for a project. All broken down into sections, typed out with computer illustrations and videos! Emailed to me. It's really a booklet. I'll start working on it and hopefully get it completed in a few weeks as time allows. I'll make any necessary adjustments as my generator is a little larger. You won't be disappointed if you order a set of building instructions. 👍☺

This video makes me believe that there is not only hope a quieter generator box but for people as a whole. Thank you so much for this wonderfully thoughtful presentation. I will no doubt implement many of your innovative ideas when building my box in the weeks to come.

Out of all the generator quiet boxes I have researched here on RU-vid...... your's impresses me the most. I also enjoyed how you switched back and forth several times showing the difference. I will build this one for ours. Thanks!!

Just received your plans for the "5X Quieter Generator" - very pleased with the quality and your response time! You obviously put a lot of time and thought into them. Thanks for making them available.

I've watched a number of YT videos recently on building sound deadening enclosures for gensets, and I have to say most of them left me wondering 'why bother', as the reduction was pretty minimal. Then I happened across this. Outstanding - both because the thing works amazingly well, and your careful, well thought out and thorough demonstration and explanation. And, importantly, without sending the viewer to sleep. Excellent work my friend. I'm hoping I can find the Rockboard product (or equivalent) here in Australia, and I'll be building something based on what you've show here. Thank you! Edit... and I should add - subscribed!

*5* Star This has to be one of the most intelligently created sound suppression boxes I've seen on youtube. The video production and quality are top notch!

I have watched a lot of different videos on building enclosures to quiet generators. Yours is by far the best, thank you for your time and effort.

Noise damping is one of the biggest challenges I ever faced in my career, second only to cooling. I am quite surprised at the results. Bravo.

Thank you so much for sharing your project. I know a lot of thought went into the build as well as the presentation. Usually, I would just build something and share with my friends. It takes a big effort to film and narrate effectively. Thank you for your effort. Very good design.

This is the best tutorial Ive watched on such a project, and I have watched a lot as I need one for my compressor and will also be buying a generator soon. Thank you very much for sharing.

This is an awesome video! It was very informative showing the decrease in sound as the project moved along!!!!!

Wow! For a First Video attempt yours is Excellent. Informative, Professional, and Easy to Follow. Can't wait to see your Instruction packet. Well Done Sir.

The quiet box that you made is simply amazing. Excellent job and great job on the video as well.

Sir. I'm not one to take much time on commenting on videos that I watch, but with video, I am making an exception. Other than your VERY MINOR issues with sound levels, you put together not only the clearest and simplest instructions, but one of the most pleasing videos to view. You seem like a man that has great karma. Please continue to take your time to show us some of the useful gizmos. I, for one, need all the help I can get! I just found a wonderful channel to find it. Again, sir, THANK YOU. EXCELLENT JOB. OUTSTANDING.

One of the best informative presentations I have watched on "tube" - Thank you for some great ideas

REALLY well done for a first video! I appreciated the time stamp at the beginning to skip the intro (although I didn't use it!) as well as the sound comparisons throughout. I'm going to email you right now for info on how to purchase the plans because I'm really impressed with the quality; simple yet full of "features"...along with the ability to break it down into parts for storage or transport... brilliant! You even took the time to give a shout out and a nice plug to your supporter. Thank you!

Sir, You have one if not the best effort with empirical data/evidence supporting your box design. Thank you for the effort in explaining the concept and reasoning. I especially appreciated the effort with the exhaust. Thank you!

I looked at a lot of home made boxes and I think yours is the quietest and very simple to make thanks for your sample and very understanding explanations of the box and how to built it Thank you

Nicely done, very simply laid out with concise explanations of assembly with real time sound results. I love the pin idea for retention and easy assembly and the intake and exhaust baffles were a nice touch.

Very good job first time videographer! Clear, concise. No mumbling, no stumbling. I thought you a professional! Are you a teacher, professor, corporate sales rep, speaker? I subscribe now. You've provided this gal everything she needs to DIH - "Do It Herself"(if I didn't already know to build, I sure would after all of your patient, thorough instruction). Using that kind of insulation is an eye opener, I hadn't gotten that far in my own portable version design. Excellent idea! Howdy from North Texas, where we wish we had island breezes to dissipate heat.

This is by far the best video and most successful outcome of a quiet box build I've seen on RU-vid and I've watched lots of them. The box I need is for a compressor which runs loud enough to wake the dead! Your video showed reduction going down at every stage and by very impressive amounts. I think you could have gone down a bit more by sitting the whole unit on thick carpet or a rug to reduce the amount of noise transmitted by the floor. I think there is a real need for this amount of sound reduction as the cheap compressors and generators are becoming more and more popular. I was planning to get rid of the compressor I just bought in order to stay on peaceful terms with my neighbors, after seeing what is possible on your video, I've changed my mind as I don't think it will be any louder than a domestic vacuum cleaner once it is boxed in - we shall see! Thanks again for a great video.

EXCEPTIONAL video. Clarity and detail are amazing. Could never build this on my own due to lack of tools and knowledge but I could see how DYIers would love it.

I look forward to receiving my step-by-step instructions. This video is well-done and the solution is ingenious! Great work!!!

Love what you did here. Excellent presentation- thank you very much for your work in designing and then doing a video on it. Outstanding work!

Excellent work. No detail left out... especially the rounding of the corner edges of the lumber! Now I have something to do with my Rockwool remnants. Wow!

This is by far the best sound reduction box that I have seen and I have watched a lot of videos. Very impressive design.

I finally started building your design a couple of weeks ago. My generator is a larger Champion model than yours (#100419, 9000/7000W on propane), but the Duromax 10000 plans that you include in your package are very close to the required dimensions, so I used that version and made the small necessary adjustments in dimensions. I did a lot of searching to find Rockboard RB60 in my area, eventually located a soundproofing construction company that had a bunch in stock, and they gave me a good price. I built the larger version of the RB60 cutting jig that can accept full width or length of the panels easily. I just happened to have a 30" x 60" work table, and the jig fits it perfectly. I visited the local thrift store on a lucky day, and bought a set of 4 serrated 8" kitchen knives for $5.00. I couldn't believe how accurately and cleanly I can cut the RB60! The panel frames are done and went together like clockwork, even with not-the-best quality selection of 1x4s and 1x6s at my local Lowe's. Your instructions for straightening the edges of the 1x4s are magic, and made assembly a piece of cake. I found the 3M Super 77 adhesive in 16 oz spray cans at the local Ace HW, but I've been putting off permanently gluing in the RB60, so as to do it all at once. I'm not sure how long those cans will still spray properly, once they've been used and then stored for a bit. Instead of a Vornado 660 fan, I'm shopping for a centrifugal (squirrel-cagel) fan with rectangular flange-mounting to attach to the end of the box. One of your commentors indicated that the centrifugal design pushes air better and won't cavitate as easily as a conventional circular fan. The Vornado 660 provides 584 CFM maximum, so I'm using that as my requirement floor. I'm researching cheap remote temperature sensors that I can disperse at various places in the box, to monitor for high temperature hot spots, or at the very least, exit air temperature.. My box will be outside all the time, so I used 1/4" exterior plywood for the panel skins, and I'm considering using Bote Cote epoxy to seal them up. I'm also looking at a conventional roof added to the cover, perhaps hinged with support struts. I'll add my admiration to that of the other responders: your instructions package is among the best I've ever seen, and, as a professional engineer for 35 years, (and as a Dad assembling kids Christmas toys for 4 kids) I've seen more than a few. Also, your tips and hints for straightening wood and managing dimensions and clearances are treasures - I wish that my high school shop teacher had taught as thoroughly as your instructions do! You should write a woodworking book for beginning hobbyists, one that teaches how to build accurate designs using suboptimal materials. I have no doubt that it would be the best such resource ever produced!

This is the best I've seen. Most only tone down db. Levels by 10 points. Thank you so much I bet I could even run this in my garage with carbon monoxide alarms!!!

Inspired by your train of thought in planning every detail. Ingenuity at its best!

This is the best video on this subject. Everything was clear, well thought and well explained. Really appreciate your efforts. More power to you!

Great job! I just installed Roxul AFB (zero formaldehyde unlike their Safe 'n Sound') batts 3" thick between my neighbor's and my double condo wall. I then put 2 layers of Homasote soundboard 1/hick each over the batts. I still plan to double all that AND add something like Quiet Rock. I haven't heard my new neighbors yet and I am only half way finished! These ideas work. They really do work well. Thanks for helping me think through a generator box for a food pushcart's generator in this excellent video.

I've been watching a lot of videos on this, & yours is the best by far. Box looks,& sounds awesome ! The video was so detailed that I can use it as directions to building my own. You just earned a sub. Great job!

Very nice video. Well done. I bought a set of plans and was very impressed with the details and sketches. I am a retired engineer and I could not have done a better job with the details.

Mahalo for the excellent video. I recently bought 5kw portable generator and have been researching quiet box projects on YT. Yours is by far the the most well thought out AND TESTED one that I’ve seen. I especially appreciated your use of the graphic sound meter! I’ll be building one similar to yours and will keep in mind the two tenets: sound doesn’t like corners and close the gaps.

The engineering and ingenuity is self evident very nice work Mr. Gizmos

Yours is one of the best and most total quietbox designs. For heat reasons you have to have a fan included and yours does. Zombie Box makes one like this for about $2,500 shipped.

Fantastic video! I greatly appreciate the info and all of the comparisons. Great job on the design of this box! I'm working on a design of my own and have taken great inspiration from your design. Very well done, and thank you for sharing all of your hard work!

I watched this video years ago. Now I watch it again, and I still thinks that it is the BEST in this subject.

This video is so wholesome and informative wow. Engineering and design of this DIY is THE best on RU-vid! Keep on keeping on!

Most effective design I've been able to find. And, I have looked. Thieft is a serious problem in my area. When the neighborhood is as quiet as it is, during an outage, I can make it look like my power is out but stay comfortably safe (camera system/alarm) and fed on the food that won't be wasted. I need to design something similar for a small a/c window unit. Thanks

Thanks for taking the time to put this on video. I was looking for something exactly like this; in fact, exactly this.

Fantastic video. Loved the model. Great job. I will definitely use your ideas to build mine. I sincerely appreciate you sharing this information. 👍

Thank you, I have this exact problem, but with a larger generator. You have very clearly and with great detail showed me how to eliminate my 70db problem. I will start looking for the materials today and then hopefully you have solved my noise problem. This is one of the best videos ever watched.

Aloha Uncle Usefulgizmos! Mahalo for this very useful instructional/testing of your sound reduction design. Four years later I come across your post and have since built your design for my use and works very well. I especially like the modularity for ease of breakdown and storage. Great way to be "low-key" when running a generator in a blackout situation. Well done and again, Mahalo! From the "Mainland".

Great job. Since my home is in an isolated rural area, my needs are not that demanding, but if we choose to go this route I will definitely consider ordering the plan.

Very impressive! For a first video this is a job well done. Congrats!

This is insane!!!!! So well done and presented, I watched it with a smile like it was my favorite TV show.

This was an outstanding presentation@! I have watched many videos on making generators quiet but yours is the best. Thank you.

Awesome simple straightforward no nonsense video. GREAT JOB!

Outstanding !!! The best and most practical video I have seen on the Noise problem of emergency power generator...BRILLIANT !!!

You certainly did a stellar job on this sound box and the logistical thinking involved. I store my generator outdoors with a rubber sheet over it to keep rain or sprinklers from ever putting water anywhere on the generator. I will probably use your method putting a roof on top a foot or so above the top baffle so rain and snow don't interfere. I really like your method with the pins and exhaust removal. I might need to transport it so my older relatives can use it if need be. Rarely does everyone's power go out at the same time here. Of course everything is subject to change and it can happen.

What a great idea! Good job! I Live in my Rv and not upsetting others when running my Champion Dual Fuel generator is always a good idea. I'll adapt it for my specific use but what a great idea and design! Thank you!

Spectacular job! what beautiful design and so effective. By far the best solution I have come across.

Incredibly awesome kind Sir! Wow! You are a "cut" above. Thank you. I must do similar; for I have just got my Westinghouse 12,5000 KW Generator, Sunday last before. So, after watching your video; I have bought 8 sheets of that 2" thick; "Ruxol RockBoard 60" insulation; to be in installed in the entire inside; of my new "Suncast" shed. Can't wait for what you have done for me; to make it better! Sir.

Very well done! Thanks for taking the time to share your design and it was very well presented.

excellent planning and execution of both the box and the video.

thanks for taking the time to share your design. much appreciated!

Wow! Very well done and thanks for sharing. I look forward to your other videos.

Good Job ! Getting your plans and building it is now on my to-do list !

Wow. Just wow. I've seen a lot of quiet boxes on this RU-vid that didn't quiet anything, but this! It's s awesome.

This is phenomenal! Thanks not just for your idea, Sharing it, but the excellent video and narration!!

I am definitely going to save this video. I just bought a 4375 Watt Champion Generator. This will definitely help when I use it. Thank you so much for this tutorial.

This is how I'm going to keep my air compressor quiet. Thanks for the idea!!

I purchased the plans in December of 2020. I have never built anything out of wood but with these plans and the super fast response to my questions I built it. The packet has several tips on improving what you see here and for what the plans cost it's a no brainer to purchase the plans. This is the best system and outstanding support after the sale.

This is the BEST silencer I've seen from many RU-vid videos! Two thumbs UP! A lot of the newer generators manufactured lately provide Carbon monoxide sensors that shut the generator down if it senses carbon monoxide... One thing I will stress here is that IF you're going to run a genset in your garage I STRONGLY SUGGEST INSTALLING A LOUD CARBON MONOXIDE SENSOR IN THE GARAGE and IN THE HOUSE! EVEN IF you're running that exhaust tube outside and up above the roof. In the event that the exhaust clamp vibrates loose or exhaust flange gasket fails. Better a few dollars spent on extra safety than on a casket!

Great video. Very clear. I immediately made improvements to my quiet box. Thanks very much.

wow what a great design to make it super quiet

Very well done Sir! Thanks for posting!

Best generator sound proofing box that I've seen so far. Well done!

I am excited to putting my box and system together. I will share with you on what I have done. Thank you for all the helpful points. Jeff

Thank You for taking the time to Make this video👍

I like that box. Easy to assemble as I get older.

A really good video. I enjoyed watching it. It will be very useful when I build my own box. Keep up the great work!

Im blown away.....pure genius!

Just one really clever variant of noise reduction box. Superrrrr

Great! As my generator (And all small gennys) are not water cooled, it's really noisy with no water jacket to dampen noise. This looks ideal. Thank you.

Great idea and appreciate your instructions and putting this video together.

Excellent job and presentation! I am totally satisfied with the results I achieved using your design. The only change I made was placing the generator on a thick rubber mat which noticably lessened the sound level even more. Again, great job and thank you for your efforts.

Serious talent here. Must be an engineer. Well done. I will order plans. Thanks.

Very well explained, and a very thorough job with the build! Thanks!

Great video and an extremely well executed quiet box.

Great idea! I loved the video. So much information and a great presentation!

This is very well thought out. Thank you!

Why don’t more people realize that baffles work or should be used? Good video. You helped me in my generator quiet box design. So few baffle designs out there. Thank you. Nice work.

Excellent project, I have been wanting to do something similar and your well thought out solutions are a perfect fit. Well done and well presented, thanks!

Good job. I did one recently using a permanent setup with carrying handles for my travel trailer using an already quiet inverter generator inside. Setting up an auto start/stop and an extended runtime aux fuel tank, I don’t have to leave comfort of my RV, and it’s that quiet you don’t even know when it cuts in or out whether inside or outside the unit.

This is an excellent installation. Thanks for sharing.

Shoots cuz!! Awesome 💪😎👍 plz keep on sharing, we all could use and benefit from creative and thoroughly thought-out ideas such as this one! Stay blessed and safe out there during them hurricanes and bad weather 🙏

You're a very smart man. This was very interesting.

Perfect design snd and power for large camper.

Watched this many times. Love it. Very detailed. Appreciate it very much.

Very good vid. Very well explained instructions and informative. I will attempt this for my generator

The best logical video i have seen , great thinking and time explaining your process of construction of the sound box // very satisfying and understanding

Such an excellent video. Thank you

Insane amount of detail, kudos to you sir!

Nice, well-thought out project. Thank you.

This is amazing! Thank you so much for this!

Looks like i found my weekend project. Great video!

Nice design....I will be trying replicate this. awesome. thank you for sharing this!

Awesome. The best video so far. Very detailed and well explained.
