How to make a generator quieter

How to make a generator quieter - 9 Ways That Work!

День тому

Wether you own a traditional portable generator or a quieter inverter generator, you might still have noise issues depending on where and when you're using the generator. This video will show you 9 ways to make your generator quieter for camping or home use.
You don't need to spend a lot of money making a portable generator quieter. Of course you could buy a generator quiet box which I cover in the video but there are easy and cheap ways to get good results.
Building a DIY quiet generator enclosure is one sure way to make your generator quieter. But you also don't even need to go that far, you can use just a couple of pieces of plywood and voila, ill show you how to do this in the video.
Here are the recommended products I talk in this video to make a portable generator quieter. The first items is what you will need to build your very own generator quiet enclosure.

When I was in the military while in the field we used generators. To quiet them, you dig a small hole and surround it with filled sand bags, little higher than the generator . Totally absorbed the sound!

Exactly. It comes down to basic principles of sound transmission. Dense materials like sand / pile of rocks will do far, far more than some kind of BS frame or enclosure.

Thank you for sharing this nice video. I apologize if someone else already mentioned what I am about to say because there are currently 397 comments to dig through. People need to be careful modifying the exhaust systems on an engine. All engines have an ideal amount of back pressure required to achieve the most power at the least amount of heat out of the engine while compromising a bit of power loss for noise reduction. There is usually a sweet spot that the engineers already hit for you. Maximize power, reduce heat and decrease noise. When you add another muffler you could be significantly increasing the backpressure on the exhaust port of the cylinder(s). This will reduce power and can also affect carburetor jetting efficiency. The noise mat and sound suppression box are a great approach so long as the engine has proper ventilation. If you stick it in a box, the oxygen level in that box will drop and that will cause the engine to run richer in fuel. So assuring the air intake at the air filter is closest to or outside of the box would be best. All of the better engine companies do extensive testing to maximize the output of their engines. When they run their tests they do so in varying environments such as high altitude, cold climate, hot climates. However they do not assume someone is going to put the engine inside of a box and this could have a detrimental impact on the engines lifespan / fuel consumption and performance. Ok, preaching over with now.

@jameshawkins4419 Рік тому

The ideal amount of back pressure is always zero. Any amount of back pressure will reduce power since it requires the engine to do more work to expel the exhaust gasses. Exhaust tuning revolves around pressure waves and their termination. By altering when the pressure wave is terminated, you change what RPM peak torque and power occurs at by making use of the scavenging effect to increase cylinder filling at specific RPMs. That is what hot rodders do with headers and muffler placement. Car mufflers will flow more than enough for any small engine to not add back pressure, however it can change when the pressure wave is terminated and that can change when peak power occurs. Since most small engines operate in a small range of RPMs, 3,600 or less, a shift to a higher rpm would be noticed as a loss of power in the lower operating range because the engine will never turn enough RPMs to achieve the new peak scavenging.

I used to have one of those 2-stroke, 800 watt Harbor Freight generators. Chincy little thing, but it worked quite well for running some lights and fans during camping on hot summer nights. I put the 'genny about 100 feet away, over a hill. Then a 10 foot long bit of electrical conduit large enough to slip over the little exhaust outlet with the spark-screen in it. A small hook clamped about 5 feet down the pipe where a bungee with a metal hook was connected, then the other end connected to the frame of the 'genny to keep the pipe tight against the exhaust. Finally, a Y-shaped branch jammed firmly into the ground to support the far end of the pipe. By the time the exhaust had exited the pipe, it was barely warm. All that, and a few bits of wood stacked as mentioned. This was in a state park campsite. During the still hours of the night I could just barely hear the 'genny. I asked neighboring campers if they heard anything, and if so, if it was bothersome. Nobody, not even the park rangers could tell that it was a generator only 100 feet away. It sounded pretty much like a window air conditioner running across the street. With little load, one full tank lasted all night, and long enough into the morning to make coffee. I sold it to my brother 10 years ago. He still uses it on jobs. Now I have an inverter 'genny. I still use the stacked wood method, but with 2 inch thick, rubberized-coated Styrofoam insulation boards rather than plywood. (Leaving openings for air and fully open on the exhaust end) Cant hear the thing at all. ALWAYS.. ALWAYS! Secure your 'genny with a lock and chain around a tree at least 6 inches thick. Junkies & crackheads are everywhere trying to steal anything to sell for their next hit. CHAIN IT UP!

Or were they styrofoam only? If styrofoam only what doyou use to keep them from blowing away? What kind of styrofoam? What was the rubberized coating? Rubberized Undercoating? A thin rubber mat? Thanks in advance.

@Cammi_Rosalie 5 місяців тому

@@webstella What I had was some kind of underlayment my uncle got from a jobsite he worked at. An insulating foam that goes under the steel sheeting. Basically, it was a panel of 2 inch thick, white strofoam with this black cating on it that was elastic and rubbery. But it looked like black cork. I have never seen anymore of that stuff since. But I never really looked for it either. Ok I just googled several keywords, and nothing similar comes up. I was trying to give you a link to a photo or source, but I'm having no luck. The closest thing I could find was Polystyrene "Sandwich" board. But it has metal cladding rather than the rubberized coating. As for the method I used to keep it in place, I used landscaping fabric pins. I just pinned then together in a 3-sided box shape and put it over the "genny, with the exhaust pointing out of the open end. Sorry I couldn't give you more info. I really do wish I knew what the stuff was called.

I always advise against #4 - car muffler. It doesn't make a significant difference AND more importantly it'll increase the back pressure on the engine causing premature failure.

@robertbagnall4868 10 місяців тому

@JV-io3nn 10 місяців тому

Even a muffler for a 1.3l engine is not going to create any real back pressure in these tiny generator engines. It will not shorten the engines life. Best practice is to use a motorcycle/scooter muffler, with the scooter muffler designed for smaller engines similar in displacement to a generators engine.

Honda inverters generators are insanely priced too (repeatedly mentioned in the video). If I could parallel 4 of them, I'd finally have a decent sized generator but I'd need a bottomless wallet to due it. It's not hard to be quiet when you're running a Cox 0.049 engine (exaggeration) and take your fuel consumption ratings using 1/4 output (when output is already 1/2 regular generators. Other manufacturers rate sound output and fuel consumption @ 1/2 output, not 1/4. Let's try some apple to apple comparisons. The inverter don't enter into the reason they're quiet it's because they are 1/2 the size both in output power and engine size (or more) along with twice the price tag.

Great video. I live in a tropical country, and have a genset in a subdivision where houses are stacked wall to wall. Overheating and noise is indeed a great deal. I came out with an idea and will hopefully develop it in the future. For those non-engineers, changing the muffler (I haven't done it but decided not to invest on this) maybe not a perfect solution, as the mufflers have internal plates called baffles that are spaced according to the frequencies generated by the exhaust gases getting out of the engine. This gases comes out in "pulses" with a certain timing. Meaning with this, that a bigger muffler just will make the sound bounce inside like the shed example he mentions. Making even a cardboard double walled box with polyestierene foam within, everything duct-taped to make it collapsible for storage, and a small air extractor attached to one side to avoid overheating should work. Mine has a 12v output, and I will plug the fan there. Great video buddy, you solved me a problem! Thanks.

I've had a generator for about seven years now and haven't had to use it for longer than an hour. However, with the recent weather patterns lately, I was wondering about muffling the noise cheaply in case I do have to run it overnight. I like the third option of blocking the noise by placing plywood around the generator. I would probably glue some some soundproofing foam on the plywood and also place a rubber mat underneath the generator. Thanks for the tips!

@Blackinterceptor999 3 роки тому

I'd probably do a combination of lowering the generator in a hole, AND building a sound controlled box, a car muffler (stock ones for a luxury car or a truck tend to be the largest mufflers)...also...raising the tail pipe itself up into the air so the left over sound is well above your ears and provides more distance and I mean like roof level....I have also heard of using a big bucket of water to help absorb exhaust sounds...Anything we can do to lower the pitch of the sound will also help. Also, keeping it well maintained helps.

Oh, man I wonder how long before the box would catch fire with my 8500 watt genny. We had a power outage a few weeks ago and can run the entire house on it, plus one AC. The muffler glows red, you can see it at night. If you stand 5 feet from the exhaust, your legs get hot. This is at 50% load too! Imagine if we cranked up two AC! One thing I can say, enclosures do work, provided they are designed with cooling and exhaust ventilation in mind. For example, look at the Generac 7.5Kw genset. Its basically the same as a caged generator, but in an enclosure. The key though is that it has plenty of ventilation and the exhaust is piped out of the box so it doesn't release its heat inside it. I also know that the alternator in the genny has a good sized fan to suck heat out, so making sure there is good in flow and out flow is key. If you do make an enclosure, make sure the front and back, in relation to the genny, the front would be the motor side, the back the exit of the alternator where the air blows out, and some method of getting the exhaust out, and it will work. Give at least 12" clearance all around. Here is the MOST important ting, Make sure you can open it up to air out BEFORE starting it! Gas fumes can and will accumulate in the box and if you have a power starter, and you push the button, you could very well go BOOM!

I know this video is older but just fyi. There are recent vids showing that a few dollar piece of drywall leaned against the gen at 45 degree angle deflects the noise from the gen into the ground really really well. You would do this between you and the gen and with exaust facing away like you have in this video. Also there are vids where people demonstrate that the crank case emits most/more of the noise then the exaust. The cheap mufflers on the gens actually work quite well. Separately from the above it did make me wonder if a generator in a large hole in the ground would work really well.

I already have the electrical connections to my outside shed so that I can put the generator in there if need be. However, I wonder if the generator will choke from the CO2 in there?

@soundproofguide 4 роки тому

I wouldn’t worry about it, just leave the door open a bit and that should be all you need. Most small sheds already have built in vents on the top of the wall close to the roof, look for those and that will also be sufficient in letting most of the fumes and heat out: it really all depends on the climate you live in. Myself, I live in a cold climate when the power is usually out so I don’t really have to worry about my generator overheating. A small shed can also echo quite a bit so it wouldn’t be a bad idea to throw something in the walls of the shed to absorb the noise of the generator. Don’t bother with acoustic panels in a shed, old blankets hung on the wall will do just fine, just make sure they are secure and won’t come into contact with the generator of course. Cheers

Obviously - buy a quiet model first, but after that use the landscape to your advantage - put in a dry ditch or behind rocks, or dig a pit and use the spoil to fill sandbags or fabric bags and place around it like sand bags. Stagger an entrance for access and exhaust as sound does not travel around corners well. Then use an old soggy plywood roof, or use earth on top. Parking it on planks or a board supported at the ends like a bridge will prevent the ground vibration problem.

James Condon did a video back in June 2020, where he bought a used generator that had a car muffler installed by a previous owner. He used a decibel meter and found the generator had around a 70 decibel sound level with the muffler installed. He then removed the car muffler and installed a factory muffler and the sound level was then 75 to 76 decibels, so the muffler did quiet the generator around 5 decibels. He had the generator setting about 25 yards away from the decibel meter when testing. Now the car muffler did have a down pipe on the exhaust side of the muffler so the sound was going down into the ground, and the factory muffler was pointed however it was pointed as installed, so that might have had some effect on the sound too. Personally, I don't know why generator manufacturers don't just put better sound deadening mufflers on their generators. Obviously the intent for a generator is to generate electricity a short distance away from it's intended use, and a muffler is intended to quiet exhaust. Why can't the manufacturers combine these to processes? Granted you can buy a Honda generator, pay a couple thousand dollars for what you can pay a few HUNDRED dollars for with any other generator, but the Honda units are supposedly the quietest generators you can get on the market. Oh well, maybe someday it'll actually become a thing. Great video with good info. Thank you.

Hello there, I am really looking for some advice please. I have just purchased an air compressor to help me operate a cup sealing machine -I found out I also need a generator to power the compressor as its a 2.2kw and unable to use with my home switches without having to go through a whole bunch of electrical work. The issue now is I have a compressor with a 97dB sound and a generator with a 74dB. My solution is to buy a garden shed and then stick the 2 machines in there and off course soundproof the shed. The generator is an LPG hence I wont have to use petrol. I am looking for advice on how to soundproof the shed as these machines will be working along side each other. Your help is much appreciated regards Dela

Moving the generator away from the house requires wire gauge considerations and becomes important ... the longer the wire ...greater the load loss. Can become very expensive.

So a tiny hole in your box will make it useless, but leaning plywood against your generator will greatly reduce sound? I'm confused now lol

@YourMajesty143 4 роки тому

Unlike a box, the plywood is angled so that the noise is directed downward. A box is not angled, it's just 4 vertical walls which keep the sound inside without any directional focus. So a hole would disrupt the acoustics from being enclosed inside.

He said leaning boards will reduce the noise by 10 decibels. A hole in the box will let the sound waves out. You are trying to compare apples and oranges.

@OlGoodJoe 2 роки тому

@@user-1A-2A These are two different sound dampenings going on here. Angling the boards against the generator deflects the sound downwards and into the sound absorbing grassy ground. If it were concrete it would not work as well. The other was a cabinet where it is designed to hold the sound waves inside the box and just like a damper in a speaker box if there is a hole in it, the sound waves will escape.

I run my generator in my DETACHED garage. I don't have a problem with heat so much as the generator being in an alcove and it choking itself out on it's own exhaust. All I did was buy a cheap box fan, plug it into an outlet on the generator, set it on the end of the unit and leave it turned on. I have my generator connected to my panel through the 240 VAC @ 50 amp twist lock so I have 4 unused outlets. When I start the generator, the the fan starts with it cycling fresh air to the intake and keeping the unit cool in the summer.

Built my own "zombie" box with 1/2 plywood and 2bys, 1st I heard it called that, anyway used a 12" 1600 fps soffet fan that blows into a 1foot sq exhaust port or box that blows into the earth down outside of the enclosure to keep it cooler and 4 directional 4" intake tubes, (tin exhaust tube) on opposite side and 4 2" vents up top for heat to escape after shutdown. Has 1ft clearance on sides and 2ft above generator. I used rockwool on front, rear and top, it's fireproof and its very quiet at 50 ft, just a slight hum for a fully featured Westinghouse DF 9500watt, has 3yr warranty. Steer away from HF, Chinese junk for same price with no extras, warranty or features! Did put a small desk fan in back that blows across the cylinder, hottest it's ever got out of airstream was 130 on a 100 day, take off any useless heat guards. Has over 1000hrs and can't complain yet! Remote feature is also great.

I mounted a 250 amp dc alternator on the engine of one of my little Honda cars. Then I wired it to a 120/ 240 volt ac inverter . I have a breaker power box that allows me to plug the 10,000 watts inverter to my house through a throwover switch. With an adjustable throttle cable, I can park the car outside my garage and plug my house into the cars power inverter and power most of the house with a cord we got from a trailer house we got rid of some years ago. Our propane house heater is no problem, but can only run one ac unit on the house. But everything else works fine. And you can't hear the car running at all. And since it's water cooled it never overheats. It's the car we take camping, so we always have all the electricity we want. Thought about building a generator head attached to a car motor on a trailer, but this works good as is. And easily portable. You can barely hear the car running.... And the best part I'd it sips gas and I can drive to to the gas station for more gas.

@davidschipsi1316 3 роки тому

Any box should have fresh air only duct, vent, opening to cool the engine and gen head made in such a way that the intake air does not mix with the heated air under the box. The box will pressurize and will need a vent back out. An exhaust fan will not be sufficient to keep heated air from recirculating though the engine and run too hot. The engine carb intake should have new air also. This is how Enclosed generators work. The front of the engine and the back of the gen head is where air is pulled in.

@Bwanar1 2 роки тому

Don't run your extension cords any longer than necessary and if you do need to, make sure you match your gauge size to the distance and load to be used. Running too small of an extension cord a long ways could overheat, causing damage or even a fire.

@duskyman1 Рік тому

It also makes the devices consume more amps... You're actually consuming more power from your generator cuz part of it is heat. I found out a long time ago my generator couldn't start a circular saw with too long of an extension cord..... But with a short extension cord.. no problem

@christopherknee5756 Рік тому

You are the first person I have read that mentions a distance at which the sound level was measured. The sound level of any engine is louder, the closer you get to it. Now, the question is, did you set the sound level meter (please tell me you didn't use a cellphone) to the A-weighting. The A-weighting filter setting adjusts how the sound level microphone hears so that it closer mimics the human ear. If you had a sound of 25000 Hertz, the sound level meter would hear it just fine. A human being would not hear this sound.

@Knight71279 2 роки тому

Bare in mind the longer the extention cord you use the higher voltage the draw will be on your generator.

@grizzlygrizzle 2 роки тому

You need a thicker cord. If you are going 100 feet, get a 12 gauge cord. More expensive, but it won't heat up and it won't offer as much electrical resistance. It's not just a matter of how much it taxes the generator, but also how much power loss you have at the far end.

@OlGoodJoe 2 роки тому

You use the proper size cord for the amperage you're feeding and for ever 50' extra length the cord is, you size up (bigger) one guage. For instance, if you're running a standard 15A circuit at 110-125v up to 50 ft you would use a cord that is 14 guage and if it's between 50' and 100' you would size up to 12ga etc. 16 guage is good for 10A at up to 50 ft.

@nonyadamnbusiness9887 11 місяців тому

Just to correct the information, no small engine is splash oiled anymore. Flathead engines will not meet EPA requirements and OHV requires an oil pump. The easiest way to deal with a generator is to make a corral of filled concrete blocks in which to run it. It only has to be as tall as the generator.

I got 2 car radiator fans and a 12v 20watt powersupply.. the fans are wired through an attic style electric thermostat so they only turn on when temps get above 110°f and they blow like a chinese hooker.. only actually draws about 1.25a or 135watts ac so not too bad of a drain from the generator also theyre only on for about maybe 30 seconds before they cool it off below temp set but are on again in 5 mins.. but do the math and its not as bad as a constantly ran fan that dont blow worth a damn. Am thinking about controlling them though and putting in a dimmer so would draw less and be better overall.. cheap also.. got fans for 20$ and supply for 10$.. think is perfect the way they already have mounting hardware included and just how damn powerful they are.. i ran 48v through one just messing around and it literally lifted a 5lb weight off the ground and hovered there.. didnt hurt it.. lol
