8 BEST Ways To Make a Noisy Generator QUIETER!

How to make a generator quieter is one of my most popular video so I decided to make an update with some new information on making your generator the quietest in the neigborhood by showing you how I made my generator 50% quieter with things I already owned!

From installing a car muffler on a generator in hopes to make it quieter to adding some sound deadening material inside the generator itself to see how much noise reduction we get AND also, placing the generator in a generator quiet box DIY versus the Zombie Box. All those sound test using a decibel meter is in this video.

Here are some of the material I talk about in this video and I recommend. All these are Amazon affiliate links which helps me produce my content at no extra cost to you, so thank you!

Throughout the video, we reference notable examples from other YouTube channels, such as James Conan's Car muffler installation and Midwest Fishing's generator quiet box build.

However, we also address potential drawbacks, such as warranty concerns when modifying your generator with aftermarket products or enclosures. We highlight the importance of understanding manufacturer policies and potential warranty implications.

If you're considering purchasing a commercial generator enclosure like the Zombie Box, we provide insights into the cost, warranty implications, and refund policy. We discuss alternatives and suggest considering inverter generators as a quieter and more powerful option, depending on your specific needs and budget.

Yes facing the muffler at your neighbor's house will make it quieter at my house. I got 100 ft cord now I put it in my neighbor's front yard. I can't hear it at all

With these recent rolling blackouts. I bought a champion duel fuel inverter generator it is quiet compared to a typical gas generator. I also bought 2 solar power stations that I can charge in under 2 hours with the champion. The 2 solar stations would keep me running a little under 2 days. I like the idea of keeping things quiet as possible. Great video!

I adapted a small broken chest freezer, removed the compressor, added casters and cut two 4x10 duct holes in the bottom for air flow. Used a 30w duct fan for cooling air. With a 2200w inverter generator inside, tests show inside temp increase less than 20f during operation. Sure its big, but easily wheeled around, and protects the gen from weather, and can be locked up. Really, really quiet!

I've seen tons and tons of videos people putting Mufflers on a generator it actually doesn't truly work because the noise that you hearing is coming from the inside of the motor and the rattling is from all the metal parts

Warranty Void? How would they know you put it in a box unless you tell them?

The easiest, cheapest and quickest way that makes the biggest difference is to run the exhaust into water. Same concept like small boats, they have no mufflers or anything they are basically like a car with short straight pipes that’s why they are loud out of the water when you start up in ur driveway but then in the water the exhaust is under water and very quite. I use a small pool made for dogs it’s about 1 ft deep, maybe 6ft wide and it folds up for storage. You could try a kiddy pool but this one is deeper and wider than any kiddy pool I’ve seen which allows the water to not get really hot. If u try it just make sure the water level is lower than the engine so there is no chance of it getting into the engine if it stalls.

I built myself A Plywood Muffler Silencer for Regular Generator Champion Generator 8750 watts, 7000 Running watts, I Reduced the Noise Down to 58 decibel at 15 ft from 88 decibel at close up. I will Soon Show everyone How I made it 😅😅

You can use a resonator extension on the exhaust pipe and it does not effect the exhaust output flow but will reduce the noise. They are used on diesel vehicles and equipment and does not affect the exhaust flow like a muffler will.

I had that yellow one. Good generator.

wonder how easy it is to bypass the CO sensor to make it easier to build an enclosure. Especially if you plan to use it outside.

I use a Craftsman 4' by 2' half height resign storage shed. When I run it I leave the top lid cracked open and one of the doors cracked open and you can barely hear it inside the house or from the front of the house.

i got the cheapest idea...used Bose noise cancelling headset...muffed alot of those noisy generators...:)

Do you know that Silicon RTV can withstand 280F ? Back in college I glued together a VW Rabbit carburetor successfully using RTV. It lasted the rest of the life of the car. That hole in your manifold could be attended to with RTV.

Here in Arizona I needed a larger generator (12, 500 w) to run the central air. I'm thinking of insulating the overhead door and venting the exhaust out with a flex pipe. I might use a high flow fan to cool the unit if I think it needs it.

Thoughts?

I have an automotive mid-silencer (glass packed) on my generator and there's definetively a difference.

[hansthenorway]

He is just a mouthpiece for inverter generators . Onan have the best generators

[markbroad]

Have you ever tried adding pipe to the exhaust into a barrel of water? Works wonderfully

[divertechnology]

so it works? it is the same from a bike?

I just don't understand how a car engine can be 200-300 horsepower and be almost silent. I have a harbor freight 8750 inverter generator and it's just too loud. And I don't even think it's as loud as some of the others. When I have it running, I can't even hear myself think, it's very distracting. You make a good point about maybe adding a muffler will reduce the engines power. but I don't see how a muffler off of like a stock honda civic or something similar would reduce power, when its made for something that literally has10 times more power than a generator like the 8750watt I have. The little muffler on mine has like a 1" hole on the exit. Do you really think a 2" muffler would affect its power? I don't think it would, but I'm not really trying to experiment on my new generator, but I would copy someone else that has a tried and proven way. That muffler you showed in the video did not make it quiet enough in my opinion. It was good that you showed that but I want mine to be silent.
