5x quieter generator or compressor sound reduction quiet box
HTML-код
- Опубликовано: 10 сен 2024
- For plans info click "Show More" below. --- Make your generator or air compressor 5x quieter using a box that can be disassembled and stored. I also show the exhaust system that prevents carbon monoxide poisoning. I show a video of my 3500 watt generator running alone, and while it continues to run I assemble a quiet box that I built, around it. The video shows the audio waveform of the generator's sound decreasing as the box is assembled, and my video editor's "db full scale" meter is also shown in real-time. Finally I show the generator running alone and compare it to the generator running in the quiet box in 3 second bursts to allow you to hear the before and after difference.
I also show how the panels of the disassembled quiet box can be arranged for storage in the bottom of a small clothes closet or in a small footprint configuration for storage in an even smaller footprint space.
PLANS: (Still available as of 1/9/22)
Cost $10.95 with no questions asked money back guarantee.
Because of many requests to buy plans for my quiet box, I put a package together that consists of plans and step-by-step instructions for building my quiet box, both sound baffles and the exhaust system. Plus bonus plans for 5 larger size quiet boxes.
I've updated the plans with optional rainshields that can replace the sound baffles for outdoor use. Also included are a video on the rockboard cutting jig and the Sketchup files for my quiet box and baffles. If interested with no obligation to purchase, send an email request for info on what the package contains to: usefulgizmos@gmail.com. (note the s in usefulgizmos)

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. 👍☺
Hi B Berthold,
Thanks so much for your very positive feedback for the plans package you received. Made my day!
Usefulgizmos hello I just bought an older generator and need desperately to quiet it fo r the neighbors sake...lol...but how could I get the I struction package that you got??
Hi Heidi,
Sorry but I missed your question until now. For details on my quiet box plans package, please send an email to me at usefulgizmos@gmail.com. Thanks.
B Berthold where can I bought it?
Are your plans brand specific? I have a champion generator would the size/dimensions need to be adjusted? Do you need the specific model of generator I have?
Thanks,
I purchased the instructions yesterday and they arrived this morning in an email. What an incredible amount of information provided!! The amount of instructions, drawings, sources, etc. is way more than worth the cost Morris asks. It looks like there would be little, if any, questions to ask. If anyone does have a question, Morris is willing and eager to try to answer them. Thanks for a great service!
Thank you very much for your kind comments. Wishing you a great build.
*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!
Thank you very much for you kind thoughts and comments. Have a great day!
I concur. A+++
Yup. Great job. I got the exact same generator and it's not as loud as many. Unfortunately many people buy a big construction generator that's 84 DB without a load, and 100 with.... And that's at 23 ft
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.
Hi Bingo,Thank you very much for your comments and kind words. ....Have a great day! ....Usefulgizmos
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!
Hi Rene. Thank you very much for taking the time to post your thoughts and very kind comments. Have a great day! .... Usefulgizmos
Out of all the generator quiet boxes I have researched here on RUclips...... 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!!
Thank you Keith for taking the time to post your kind comments. Thanks for watching, have a great build and have a great day! .... Usefulgizmos
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.
Dear cmathis1, Thank you very much for taking the time to post your kind remarks. Very much appreciated. Have a great day! .... Usefulgizmos
How much did it end up costing??$$$
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.
What a nice letter! Very much appreciated. Thanks for watching and have a nice day! .... Usefulgizmos
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
Rico, so nice of you to take the time to post your kind comments. Thanks! Have a great day! ... Usefulgizmos
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!

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.
Appreciate your kind comments Jeff. Thanks for watching and have a great day! .... Usefulgizmos
I watched this video years ago. Now I watch it again, and I still thinks that it is the BEST in this subject.

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!

When you lost power, you're lucky enough to have a generator to power your essential equipments & help out neighbors. People really don't care about a bit of noise on those days. Amen!... I have 19.5KW generator and the noise just like music during the power outage of last year huricane in Florida.
This is the BEST silencer I've seen from many RUclips 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!
Thank you Geo. Additional safety measures never hurt. Thanks for watching and have a great day! .... Usefulgizmos
Very impressive. The rule of thumb for motor vehicle silencing is "every 3 dB reduction is a reduction of sound energy by 1/2". If your decibel meter is correct (and I see nothing to indicate that it is not), you're reducing energy by 1/2 seven times; that's huge. (Reducing the sound level by 1/2 is not exactly the same as "quieter to the ear by a factor of 1/2 but it's the best way to scientifically measure and it's a good indication.)
I'd only like to ask one thing. You documented the sound level very well by showing a meter read out quantifying sound level. What would help greatly would be if you'd similarly document temperatures with an infrared thermo gun; I bought one for about $30 from Amazon and it's quite accurate and I use it for many things -- temp inside the fridge or freezer, drive an hour and check tire temps to be sure they're all the same (one that's hotter indicates possible failure), all temps of each header pipe on my RVs engine should be the same, battery temperature, etc. They're VERY useful as a tool for many uses.
Put spots of tape with a number on on your engine at a few different places. Run the bare generator under load for 30 minutes and record the temps; then let it cool for an hour. Reassemble the quiet box, run the engine again and then check numbers. If you're not getting significant increases, your cooling scheme is working very well.
And for cooling, "squirrel cage" (or "snail shell") centrifugal fans will build up air pressure and push air through a baffled path much better than a plain blade fan. A blade fan will stall out and cavitate air resulting in very significant air movement drops if there's any significant back pressure; under back pressure conditions, a centrifugal fan will build up more pressure against the back pressure and continue to move air. You may wish to try one.
Finally, a double back baffle system will drop sound levels much more than a shorter or more direct baffle path. Most quiet box systems are let down badly by their control of cooling air, you're right in your emphasis on getting the input and outlet sound level reduced for your cooling air. The excellent exhaust pipe arrangement is also top rate. You've done an excellent job and probably are reaching the point of diminishing returns so that it's really impractical to do much better.
This is very good work, indeed.
Hi Brucebear1, ... Thanks for your analysis and suggestions. I'm sure others can benefit from your comments. Have a great day!
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.
This is by far the best sound reduction box that I have seen and I have watched a lot of videos. Very impressive design.
Appreciate your kind comments Denise. Thanks for watching and have a great day! .... Usefulgizmos
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.
Thanks for taking the time to post your comments. Have a great day! ... Usefulgizmos
Can you do a video of your setup
This was an outstanding presentation@! I have watched many videos on making generators quiet but yours is the best. Thank you.
And thank you for taking the time to post your kind words. Thanks for watching and have a great day! .... Usefulgizmos
This video is so wholesome and informative wow. Engineering and design of this DIY is THE best on RUclips! Keep on keeping on!
Thank you very much Josephine. You really know how to make someone's day. And you have a great day too! Awesome pic by the way .... Usefulgizmos
Great video, and a real optimum design too. Just want to note that a 21 dB reduction in noise, as measured in the video, corresponds to over 100 times reduction in sound pressure, not a 5x reduction. It is a profound difference. Thank you for sharing.
Thank you for your kind comments. Thanks for watching and have a great day! .... Usefulgizmos
20 db is 10 times reduction
This is insane!!!!! So well done and presented, I watched it with a smile like it was my favorite TV show.
Thanks for your really kind words. Much appreciated. Have a great day!
Dear brother,
As a former Honolulu resident myself, I thank you for your video. Now, my family lives in Seattle, Washington, we often have power outage during winter times and storm seasons. I will borrow your idea and plan to build one for my Champion (7,000/6,000 W) generator. Aloha!
We love Seattle. Visited before and after our Alaska cruise years ago before covid. One of our favorite trips. Thanks for watching and have a great day! .... Usefulgizmos

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.
Hi Big Nick,Thank you for your kind comments. Have a great day!
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!
Thank you very much Rafael. Have a great day! .... Usefulgizmos
Wow. Just wow. I've seen a lot of quiet boxes on this RUclips that didn't quiet anything, but this! It's s awesome.
Yes i agree and its so comprehensive such as the sound baffles.
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.
Thank you so much for your kind feedback Larry. Have a great day! .... Usefulgizmos
Keeping a generator makes sense - China makes a dual fuel kit for $20 and w/ 4 tanks of 30 lb propane(each equals 5 gal of gas) lasts a few days. I run gasoline daytime & propane at night. Leaning 3/4" plywood(5 pcs) & adding the exhaust pipe lowers noise more than 10 db so I can sleep.
Outstanding !!! The best and most practical video I have seen on the Noise problem of emergency power generator...BRILLIANT !!!

Welcome. Thanks for watching and have a great day! .... Usefulgizmos
Mahalo for da great video. I'm in the process of building a geny stand and dog house for a portable generator that will power my house. Hopefully I'll never have to use it though. Last year during hurricane Ida we had a really small one that would only power the fridge and a few other items. Regardless,... it was really loud, and we shut it off at night. But now I have a larger one, and I need to do everything I can to make it as quiet as possible, without going out and buying a TQG from the Army Surplus Store. I have an area that I can keep mine set up year round, that is out of the way, but the design is what is important. I've seen too many that use a plastic tool shed, and hard, heat/cold insulation instead of sound deadening insulation material. I had a few baffle ideas in my head as well, and your design has fortified my similar ideas. Aloha, from Louisiana (former Kihei).
Welcome Jeremiah. Best wishes for your quiet box build. Thanks for watching and have a great day! .... Usefulgizmos
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.
Hi Berlin,
Thank your for your kind comments. Much appreciated.
Usefulgizmos
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.
In my plans package I show an alternate method of using rainshields in place of the sound baffles if using the quiet box outdoors. Thanks for watching and have a great day! .... Usefulgizmos

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!!!
Hi Doug. Thank you for your kind comments. Have a great day! .... Usefulgizmos
Very impressive design. Lots of high tech engineering in that design. Keep in mind though that many of us don't posses that level of woodworking skills and tools. Adding a temp sensor on the motor would probably show some interesting level of temp rise with the box in place that will affect the generators life span. Also the back pressure on the engine exhaust valves may pose long term issues. I just bought a USED Honda generator for $1000 and none of that quieting is needed. I prefer to let Mr. Honda's engineers do the work. I can run it right out in the open and downwind side of my house and neighbors don't even know it's running. Thanks
Slick, thank you for your kind words.
Slick said "Also the back pressure on the engine exhaust valves may pose long term issues." ........
Usefulgizmos said: I don't think that will be an issue with my design. I read that if the exhaust tubing has twice the area of the engine's exhaust, there is no back pressure concern. (tons of research so don't have the link to that info now). The exhaust for my Champion generator is 3/4" diameter so has a area of 0.44 sq inches. The flex tubing is 1-1/4" diameter so has an area of 1.23 sq inches. 1.23/.44 = 2.795. So my flex tubing has about 2.8 times more area than my generator's exhaust. The vertical conduit pipe has an ID of 1-3/8" so has an area of 1.48 sq inches. This expands the exhaust area even more. ..... So in summary, I don't have any concerns about harmful back pressure on my generator. .........
Thanks,Usefulgizmos
Wow! Very well done and thanks for sharing. I look forward to your other videos.
Thank you sir. Thanks for watching and have a great day! .... Usefulgizmos
if you slope the sides out on the bottom it also helps. /````\ like this, it directs the sound down and back. I just use plywood and this method because it takes up less room for travel. works well enough. for a more stationary setup your idea is great.

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.
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.
Thanks for taking the time to post your comments Ruben. Appreciate it! Have a great day.
I just made a frame from 2x4's and attached acoustic ceiling panels inside and 3x4 plywood outside and it gave me 90% quieter on my compressor.
Hi Eloise,
That's some heavy duty frame you made. Way more heavy duty than my frames. Glad it worked out for you though with such excellent sound reduction.
Its a tall compressor, like almost 6ft, and used to scare the bejesus out of me when it clicked on! Because it doesn't get hot like a generator or require all that venting, there are just 4, 2-inch holes near the bottom on the back side, far away from the noisy bits on the top of the thing. The front is hinged like a door so I can get at it.
One of the best informative presentations I have watched on "tube" - Thank you for some great ideas
Hi William. Thank you very much. Appreciate your taking the time to comment. Have a great day! ..... Usefulgizmos
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.

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.

Thanks for sharing your experience in blocking sound. Yes, 3" thick mineral wool does block sound transmission very well. And thank you very much for your kind words regarding my video. Have a great day!
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.
Hi Brad,
Wow, thank you very much for taking the time to post your very kind comments. Much appreciated. Have a great day!
This is by far the best video and most successful outcome of a quiet box build I've seen on RUclips 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.
Hi Martyn,
Thanks for your kind and thoughtful comments. Yes, I think you will be pleased with the amount of sound reduction that this design affords. All I wanted was at least a 50% noise reduction but the results far surpassed my expectations. Plus, in addition to excellent sound blocking, the insulation used (Roxul Rockboard 60) is relatively light weight and is extremely fire resistant. No worries about the insulation being close to a hot muffler or the hot exhaust tubing touching the insulation.
Have a great day,
Usefulgizmos
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".

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.

I'm basically building the same thing at this time but rained today so im checking others ideas. Made mine 3.5 ft by 4.5 ft wide by 42" tall, using a 900cfm fan blowing air out with a smaller inlet. Exhaust is going through a baffled chamber system on the side along with the warm air. 5 insulated corners/chambers should knock down the DBs, is a 9000watt gen. Not running any extra exhaust pipe, just a silencer off my 88inch Harley that happened to fit just right to the muffler that makes a 90° exit into the airflow exit

I had already bought a 3500w Harbor freight inverting generator. But this is a nice design. I have been considering a quite box even for the generator I bought to run at night camping.
Thanks for your kind comment Steve. Have a nice time camping and have a great day! .... Usefulgizmos
Just one really clever variant of noise reduction box. Superrrrr
Thanks for watching and have a great day! .... Usefulgizmos
What is the opperational temperature inside the box, with it completely assembled w/fan?
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
The best logical video i have seen , great thinking and time explaining your process of construction of the sound box // very satisfying and understanding
Thank you very much Raymond. Thanks for watching and have a great day! .... Usefulgizmos
Great idea and appreciate your instructions and putting this video together.
Thank you for your thoughtful comments. Thanks for watching and have a great day! .... Usefulgizmos
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!
Thanks for your encouraging words and thanks for watching. Have a great day! .... Usefulgizmos
This is the best video on this subject. Everything was clear, well thought and well explained. Really appreciate your efforts. More power to you!
Hi Manny. Thanks for your kind comments. Have a great day! .... Usefulgizmos
I copied that sawhorse miter saw stand using 2x3 sawhorse and 2x4x10 adjustable table support stand, assembly is easy.. Thank you for the idea.
Hi Sal112350, would love to see some pictures of your miter saw stand. If you are so inclined, please send them to me at usefulgizmos@gmail.com. In any event, thank you very much for your positive feedback. Have a great day! .... Usefulgizmos
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.
Hi Zecro67, Thank you very much for your kind evaluation. Thanks for watching and have a great day! .... Usefulgizmos
Keeping the generator quiet also helps to deter theft, because fewer people will know you have one.
Perish the thought.! I having anxiety cuz I just and was thinking the same thing
The engineering and ingenuity is self evident very nice work Mr. Gizmos
Hi Richard, Thank you for your kind words. Have a great day! .....Usefulgizmos
I like that box. Easy to assemble as I get older.
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!
Thanks Jack and have a great day! ..... Usefulgizmos
Inspired by your train of thought in planning every detail. Ingenuity at its best!
Thank you very much. Have a great day! ..... Usefulgizmos
Mighty impressive performance. The little Hondas only run 62 decibels, but would be almostsilent with something like this.
Thanks Sandy. Many people who purchased plans for the quiet box reported that the sound reduction of their quiet box is "phenomenal" or "amazing" (their words). Thanks for watching and have a great day! .... Usefulgizmos
wow what a great design to make it super quiet
Thank you and Happy Holidays. Thanks for watching and have a great day! .... Usefulgizmos
This is phenomenal! Thanks not just for your idea, Sharing it, but the excellent video and narration!!
Appreciate your kind words cappy. Thanks for watching and have a great day! .... Usefulgizmos
I look forward to receiving my step-by-step instructions. This video is well-done and the solution is ingenious! Great work!!!
Hope my quiet box plans package met your expectations and that your build is going well. Thanks!
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!
Thanks H Garza. Hope your build goes well. Have a great day!
Alot of work but getting down to 30db is well worthit!
Thank you and have a great day! ...Usefulgizmos
Very impressive! For a first video this is a job well done. Congrats!
Wow. I must say this is quite impressive. I sent you an email to purchase the plans. I live at a renfaire 5 months out of the year and this would be amazing to have as we have noise restrictions after 10pm. ❤
Thank you. I received your email and sent the info on how to purchase the plans and step-by-step instructions for the quiet box and exhaust system. Thanks for watching and have a great day! .... Usefulgizmos
Awesome simple straightforward no nonsense video. GREAT JOB!
Thank you Dog Training Collars. Have a great day! ..... Usefulgizmos
Fantastic video. Loved the model. Great job. I will definitely use your ideas to build mine. I sincerely appreciate you sharing this information. 👍
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.
Hi Me,
Thanks for your kind comments. Have a great day.
Great video. Very clear. I immediately made improvements to my quiet box. Thanks very much.
You're welcome. Thanks for watching and have a great day! .... Usefulgizmos
This video is by far the best I have seen to quiet a generator. Do you have instruction plans? I have my gen in a shed which does cut down the noise, but I want it even quieter. I believe your creativeness will do the trick.
Insane amount of detail, kudos to you sir!
Thank you kind sir. Thanks for watching and have a great day! .... Usefulgizmos
@@RAPTOR8ASDF And you too, all the best from the far north of New Zealand.
Outstanding video, plan on putting mine in the garage and exhaust thru the side of the house. I love the box and how it works, unfortunately for me my GF will be doing this since firefighters are usually at the station for hurricanes and major storms, and I don't see her doing all this, so I will have to dummy it down a bit with foam panels. The video did give me some great ideas though, if you had an electric start genny it would be really easy.
Hi Tom,Glad you found the information to be useful and thank you for your kind words. The Rockboard 60 insulation I used is very fire resistant (almost fire proof), has outstanding sound reduction, won't disintegrate over time and is quite light in weight so I think it's worth it. Sounds like you have a great girl friend. "Honey dos" in reverse (wink). ...Have a great day, ... Usefulgizmos
Im blown away.....pure genius!
So nice of you to say that. Thanks and have a great day!Usefulgizmos
