So it's not something people haven't considered before... but the disadvantages of having the noise of a generator letting your neighbors all know that YOU HAVE power, refrigeration, fuel, etc....
Has anyone else had it draw neighbors or family to ask for something? Sure enough we had a short power outage last year and some family about a mile away asking to use one of our generators for their freezers. and sure enough, they treated it like crap. Running it all day, running it out of fuel, trying to leave it out in the rain. Etc. If it had been SHTF, they would have been asking for far more. Family started considering ways to nearly silence the generators. All the way to mufflers and sound proofed as much as practical boxes, or even dirt sound proofing burms with a roof. Venting for intake and muffled exhaust. Any similar stories? Or anyone done anything for this reason? |

All my neighbors have generators, so generally I'm not concerned.
I do keep a cheap generator as a loaner though. |

Honda EU2000i is the quietest generator I've ever used. I also have a 7500 watt Costco brand with a Honda engine that is louder but not terribly so. Ideally you would use your generator during the day when it would attract less attention and you had better visibility/security to charge batteries that would carry you through the night providing silent power. I haven't gotten to this stage yet so I can't comment.

I have a NG-fired backup generator. It has its own enclosure, and is behind a wooden board-on-board fence... also buffered by vegetation.
All of that diffuses the sound somewhat. You can tell something is running, but not exactly where it's coming from among the several houses on my street. Of course, the fact that my oblivious children leave EVERY LIGHT IN THE HOUSE TURNED ON (so that you can practically see my house from the International Space Station) doesn't exactly contribute to the stealth. I would think that out in the country, you'd have to work VERY hard to silence a generator... if only because there isn't nearly the background noise out there to help it blend in. |

Punji sticks and claymores would make good mufflers I would imagine.

Down here they'll come at night and pull your lawn mower out of your shed and fire it up with the safety bar taped down and steal the generator...you never hear a thing.

Offer to cook your neighbors food for them before it spoils. Make it a block party.

Years ago a guy on my street had the only genny around during a windstorm that knocked out power.
Someone got his lawnmower out, tied a rag on thge bar to keep in running and cut his genny chain and swiped it. |

Back when I lived in rural CT (yes, such a thing exists), my neighbors scoffed at me for buying a generator. "Oh, we haven't had a power outage in well over 10 years." Well, a nasty ice storm rolled in back in December of 2003. Power was out for 5 days. Most of my neighbors had to leave their homes for hotels, relatives, etc., or were huddled around the fireplace freezing their asses off. As far as my young kids knew, life went on like normal. Ran the generator 24/7, and I actually turned on ALL of my outside lights, just to piss off my neighbors. I did offer our house as shelter or at least for hot showers, but no one accepted. Fuck 'em.
|
|
I figured if a SHTF and I need to run the genny, I will be guarding it as well.
We have a small shed attached to the garage which is a detached garage, we have an exhaust fan and an intake vent. I was considering some extended muffler but never completed it. All my neighbors now have gennies since the last outage that lasted a week. |

i'm currently in th market for a generator but for the reasons you mentioned i'm saving for the honda 2000 . my dad has one and it's awesome. if i had to sound proof another one i'd probably buy this and build a box, probably ad me acoustic panels behind it.

I have the 9k champion fuel fuel generator. Loud as I've ever heard a generator be. We used it for a party where we had 3 campers running on it. I put it by the field, about 15 feet from the campers and made a semicircle 3 hay bales high around it. Could barely hear it on our side, needed ear pro on the other.
After the party weekend I fed the hay to the cows. |

When I got my first about 15-years ago I ran some experiments and posted them here.
During normalcy a running motor goes pretty much unnoticed even in a crowded suburban area. Once the lights are out and traffic stops the noise level drops and people step out from in front of their screens and people get bored not so much. You can hear a running generator from more than a mile in the evening out in the desert just as you can hear a normal conversation at that distance too under the right conditions. The cool air channels sound to say close to the ground compared to a warm ground which causes sound to rise. I have an Honda 2000 and we tested it. I buried it in a box into the sand and that helps as it focuses the sound upwards. Running even my UPS system at night attracts people. The house lights and even the air conditioner compressor and cooking smells can be detected. I plan on running my generator during the day to run my AC and charge my UPS batteries. I will proactively help neighbors with cell phone charging and even entertain room in my freezer for gasoline from your vehicle trades. Getting neighbors working for you is important. |

Play on youtube. They show with decibel meter that most of the noise is from the engine itself. Adding a muffler does not solve all issues.
The box and redirecting noise upwards works best. As already mentioned, smells of food and light at night will cause folks to ask questions as well. My concept is to run stuff during the day. Use ac to cool off the bedroom in the evening. A battery powered fan will keep air moving at night and I will shut everything down at night and lock it up. Having a big ol dog out by the generator would also help somewhat. To some extent I don't mind helping people. My issue is what happens if they kill your generator? |

I recently used flood lights beaming out from the genny and lighting all access points. I figure, the lights are a great psychological deterrent. Cockroaches don't want to get lit up as they approach, and they don't know who's watching from inside the house.

I used an old Kawasaki during Irene and it is so loud I'd almost rather not have power. After that I bought a Honda 2000 and it was great during Sandy. I'm on a 60 by 100 lot, and with it in the backyard you can't hear it from the base of my driveway. Much more pleasant and better opsec.

A couple of deep cycle batts and a good invertor will keep things going while the gen is down. I have a 4k trace invertor that will charge the batts when the gen is running. I like the old school trojan 6vdc batteries. even a pair of them will have 400ah of power. A pair of T-105's can give 25 amps for 13hrs
I am in the process of building a medium size solar and wind gen with gen back up. The base specs are 1kw of panels, 1.6kw of turbine power with eight 6vdc trojans. storing 1760ah (20hr rating) of power. I can run my home (minus AC) for 2.3 days with no sun or wind on a full charge. The panels will fold up and the turbine mast will fold down for transport or high winds. I may make some sort of steel cover for the panels to protect from wind driven damage as I get there. NO SOUND!! No oil, no gas, very little maintenance during a crisis. Hard to loan out as it's on a trailer. OK, it's heavy and bulky for a 4k gen but has some long term potential. WSS |

I've been contemplating this as well.
I have a box that used to cover the well motor here . It's three ft or so high,four ft long and 3 wide. It's metal insulated panels. Two inches thick. I've thought of cutting in a roof event and brings on the sides down low. Just set it over the generator. Or Just cut open one side to SIM the sound out. We set the gen on a slab outside our back door of the utility room. Cant hear it from the road but behind the house you can. |

Our 7550 Generac is loud as hell. Hopefully, I will not need it.

You also have many more options for building an actual baffled, ventilated, sound-proof enclosure (you could even put it in a basement or an outbuilding, provided you ventilate it). I have an extra EU2000i generator (in addition to my permanently-sited Kohler) that I use whenever I have to work out in the country with no power, but I plan to use as a loaner generator if we have a bad storm. I have a little lawn-cart I could put it on, so I could easily wheel it around to my neighbors to help them save their fridges-of-food, charge phones, etc. I went through a bad storm about 15 years ago where I used to live, and I ended up loaning out my generator to a neighbor afterwards (my power came back on before his). You'd think I'd loaned him my wife... he may have been the most grateful neighbor I've ever had. Help out a neighbor... make the best of the fact that you're a one-eyed-man-in-a-kingdom-of-the-blind |

It can be done. Just look at noise isolating enclosures on commercial generators and air compressors. Any generator will require sufficient cooling. An enclosure will need to have a fan with several noise cutting baffles that will deliver enough airflow for cooling.
Also long elevated vertical exhaust pipes will disperse sound a lot better than horizontal pipes. A very effective but crude and simple exhaust system can be built by simply placing the exhaust pipe into a small barrel filled with water. |

I ran across a tail-gater at the Clemson/
Kent State game last week that was running a Honda EU2000, and I could not believe how quiet it was. It was amazing. After the hurricane passes, I'm going to pick one up to go with the camper/bugout command post. John |

in 2013 Tornado came through the neighborhood..My house was unliveable but some of the neighbors' house were intact ..I loaned my Harbor Freight 3KW out to a neighbor ..Pretty much got passed around the neighborhood and it was 2 months before I saw it again..came back in perfect shape though

What is the significance of the
GFI on the EB-2000 as opposed to the EU-2000? John |

Several years ago we had rolling blackouts at my parents' home (Los Angeles area). The sound of the genny in their RV brought the neighbors on each side over; my parents let them heat some dinners up in the microwave.

During hurricane Rita in Beaumont Texas it was reported that a running generator was stolen one night. It seems the thief placed a stolen running lawn mower next to the running generator, shut down the generator and made off with it before the owner realized he had no power. This happened late at night when the owner was asleep.

We have had threads with someone having a couple of the 2k watt versions.
I also recall in past mother nature hissy fit threads we discussed having coffee and some other stuff for the neighbors. It can help them feel normal. Letting some of the women have hot showers after several days without power can be a big thing. In a lot of my thinking I sort of have 2 ways of looking at what I have on hand. Give me a week long, heck month long, mother nature hissy fit or man made screw up and I am much more likely to help neighbors out with my supplies. I do somewhat have to say that while a cup of coffee now and then in a styrofoam cup would be free, lots of cooking and heating water and stuff is going to require they bring food and fuel and what not. This thinking is for something localized where supplies are coming from the rest of the country and you know it is a limited time event. Give me something that makes me wonder when things will return to normal and I look at things in a whole new light. Sure I might share a cup of coffee with a neighbor still, but they don't need to know about amount of supplies on hand and what not. Might downplay things big time by using the percolator on a coleman camp stove on the back porch or something. Dutch oven out in the fire pit, with a couple dogs chained nearby for doggy duty. Heck, I prep for the dogs as well and I bet some neighbors would get upset by the doggies having their regular food continue while the neighbors wonder what is going on after a short period of time. Those who know me know I am all about helping folks out, but I really want those folks to be helping themselves along as well. And my mood changes a tad when folks think I have to do some sharing and what not. |

Around here many folks (as everywhere) keep their generator in a storge shed or such beside their push mower. Many of the crooks would sneak in after dark, start the lawn mower before stealing the generator. That way the owner wouldn't hear the motor stop. Gave them just enough time to get out of the area before the resident realized that the fan or window unit wasn't running. SO, don't know what to tell you to do, but just something to think about your setup.
Doc Sorry for the Dupe Vinny. Was tired the night I typed this....... |

Not a concern as I 've learned how to say "NO". I also use a Eu2000 which is barely a mousefart.
|

I could barely hear the eu2000 outside my window over the sound of the neighbors generator. Also I sleep with a cpap and if they shut off the generator I'm going to know right away.

Oh yes, BTDT twice. Once Hurricane Alicia when I lived in Houston and once here the blizzard of 1993.
Like these guys say, if you have light let alone a generator sound, you're going to draw people literally like moths to a light. You need to secure your generator so it can't be stolen and no matter how good your intentions learn how to say "no". Best way to say "no" is offer an alternative they didn't think of for themselves. Amazing how panic sets in and people just stop thinking. Simple things like you got a candle becomes almost like the revelation of a lifetime. They just don't think about the simple things and an appreciative I care "no" goes a long way. Its always easier to steal from the butthole. Tj |

In 2003, when Isabel came thru here, I didn't have a generator. It was miserably hot and humid and couldn't sleep. Went without power for 5 full days. One neighbor had a B&S generator from Lowes that they ran constantly, all night and day. Didn't endear themselves to the other neighbors, including me. In 2011, I had a generator that I ran for 2 days solid so I could have a little portable A/C in the bedrooms and keep the fridge and freezer cold. There were 4-5 other generators running all around me so it was no big deal.
Speaking of B&S generators, one of the reasons my 5500W is so loud is that the frame is not very tight. Crank that up and about half the noise is the frame vibrating metal-to-metal. The newer dual-fuel that I bought is bigger but a little quieter. I have a Honda EU-2000i that I bought recently and used for Field Day with the ham radio club. You could stand over it and have a conversation. Same with the EU-3000i we have at work. Interestingly, the EU-7000i that we got recently to power our ops trailer at work is much, much quieter than the 15k BTU A/C on the top of the trailer. It makes noise both inside <AND> outside the trailer. You should consider noise discipline to be multi-faceted. It's not enough to just make your generator quieter, you also have to make sure the stuff you are powering doesn't give away the fact you have power. That includes lighting as well as A/C, pumps, etc. One neighbor now has a whole house generator. When that thing kicks on every Sunday morning, it sounds like somebody is mowing their lawn with a commercial riding mower. Whatever generator noise I make will be small by comparison. |

Have you thought about a battery bank? (Trojan Battery)
I don't run my generator now because of the noise. I have a solar array that charges the battery bank. (Tracking Solar Arrays) The battery bank provides power to critical systems during a power failure and they are quiet. (Battery Banks Powering your Home) |

Some good ideas/thoughts posted.
Rural area. Longish driveway up to house and a LOT of various outbuildings. Live 20 minutes from town. There are some families, and some empty cabins. It's a lake property street. Not packed in, but a semi-dense area as far as super rural areas go. For power outages (couple days to a couple weeks) Don't want to make any enemies over such a easy time (for my family). Will let people charge phones. Can share some food. Anything longer will mean less for others. Less gen running time even for us. Still can't make enemies though. Don't want to be the excluded ones in such a rural neighborhood. Then you don't get a share of the garden veggies, told when someone is running into town for stuff, other opportunities, etc. But my family's house has never had AC, and even now in my apartment I haven't used AC for half the summer (waiting for replacement unit). I can't even comprehend using a generator for anything besides fridges and freezers. Open windows at night, close in the morning when it starts heating up, and then open them again once the temp outside is cooler than inside in the late afternoon. Repeat every day. |

Since you guys brought it up. Years ago during a visit to FL, I had the opportunity to canvas a lot of Fl folks on their generator usage after a hurricane. It was quite interesting.
First thing they noted is during the day, they were at work. A power outage at home really isn't a good long term excuse for missing work and money kind of comes in handy for paying bills and rebuilding. Letting their generators run unattended during the day was also not a good idea. That meant most of their running time was in evenings. Most also said that fuel consumption impacted planning of how much and when as anything did. Many ran their generators in their backyard even putting holes in their walls to run the cables to limit "Stop and Grab" robberies of their gens. Typical was run the generator once you got home to cool down your freezers and refrigerators, then again to cool down the same and your bedroom so you can sleep at night, then again in the mornings before they went off to work. Pretty smart when you think about it some. The most striking thing to me is how pragmatic these people were on this topic compared to those of us so far inland one week outages were rare if ever. That and my own experiences gave me a saying. How do you know you were prepared for a disaster is you aren't the guy with an empty can wondering around trying to find something you should have had in the first place. Tj |

Day three without commercial power here from Irma.
Never heard so many generators in my life. In rural country here, you could stand outside and pinpoint each one at houses 1/2 mile or more away. Farthest one at about 1 mile seemed to be the loudest. Made me really glad we focused on adding more to the solar input. We still have the diesel genset, but haven't run it except for exercise in the last couple years. |
