With the unexpected rise in severe weather, we all know how crucial having a generator is these days.

There is a substantial risk of a power outage in my neighborhood due to a big volume of freezing rain expected tonight.

For some individuals, having a generator is important, particularly if they have children.

The major issue with most generators, though, is the amount of noise they produce.

In this essay, I’ll go through some methods for making a generator quiet for camping and residential usage.

How can I make a camping generator quieter? Building a silent generator box is the greatest technique to make a generator quieter for camping and at home during a power outage.

How to make a generator quieter – 9 Ways That Work! – Soundproof Guide

By following the link, you may learn how to create your own DIY generator silent enclosure.

There are, of course, various methods to make a generator quieter so that it does not annoy others.

I’ll also discuss the various kinds of generators and how to make both conventional and inverter generators quieter.

When I go camping, I don’t use a generator.

Because we frequently travel to regions where a trailer couldn’t go, our family still sleeps in tents when camping.

I do, however, have a generator that can power certain areas of my house during a power outage, and I have felt horrible for my neighbors in the past when my generator was rather noisy.

The fact that practically everyone around us had a generator was the only thing that made my predicament tolerable.

At the very least, I didn’t feel like I was the only one who was making such a ruckus! We now have a natural gas backup generator that is very quiet, owing to the robust cage in which it spends the whole year.

I’ll give you some suggestions for making your generator as silent as a cricket!

How to Make a Cricket as Quiet as a Generator

Small engines, such as those found in generators or air compressors, are significantly noisier than large motors seen in vehicles for a simple reason.

An automobile engine is comprised of a thick, heavy material with a high-volume oil system that is pressured.

They are liquid cooled, which prevents the engine from overheating.

Small engines, on the other hand, are built of a lighter, thinner material that is splash lubricated and cooled by the air.

Small engine manufacturers could develop engines that were more quieter, but they would have to make them thick and hefty.

I’m not sure how many folks would want to haul about an 800-pound lawnmower or a generator that heavy.

Here are some of the greatest recommendations I could come up with for making a generator quiet for camping and at home.

Step 1: Construct a Generator Enclosure of Silence

As I previously said, one of the greatest methods to make your generator quieter is to design a silent generator box.

Because we all know how noisy an ordinary air compressor can be, having a quiet enclosure for a generator may also be used to make an air compressor quieter; just make sure the sound box is wide enough to handle other loud appliances.

If you follow the instructions in the page, you may make your own generator silent box in no time.

The stages of building a noise isolation box are outlined below.

  1. To begin, take all of the necessary dimensions. You don’t want any air holes allowing noise to escape the cage. Leaving even a little hole will completely destroy the function of the sound box. Make sure to leave just enough room inside the box for the sound insulation that you’ll place on all four walls and the ceiling. You’ll also need to make sure there’s adequate room for the ventilation system.
  2. Using a circular or table saw, cut out the MDX (Medium Density Fiberboard Amazon Link) to your desired measurements. It could be a good idea to use a pencil to name the sides and ceiling parts so that there is no misunderstanding afterwards. Make sure you get enough MDX or soundboard to avoid having to do a second internet order or returning to the hardware shop for extra material.
  3. Green Glue Noise-Proofing Compound is used to apply the initial layer of soundproofing. Mass Loaded Vynil will be the first afterwards (MLV). Inside the container, there is also a second layer of soundproofing material to be attached. By visiting the link above, you may get all the information you need to finish building the speaker box (quiet generator box).

Step 2: Purchase a ZombieBox Soundproof Enclosure.

The ZombieBox is a soundproof, waterproof, and portable container.

When utilizing your generator on a camping trip, a ZombieBox will make it much quieter.

This box also has the advantage of being collapsible for convenient storage.

According to their website, the Zombie Box will minimize the noise from your generator by up to 5X or 99 percent.

I’ve never had a ZombieBox before, but I’m hoping to obtain one soon.

Keep an eye out on our YouTube channel for a complete review as soon as it’s released.

Step 3: Can a Car Muffler Be Used on a Generator? NO and YES!

I’ve seen a lot of soundproofing websites suggest that a car muffle (Amazon Link) would serve as a miraculous generator silencer.

So, what’s this? They don’t always work, and those who say differently have obviously never tried it for themselves and are most likely duplicating each other’s answers.

At first, I believed there was some truth to this allegation.

Many individuals suggested that a generator might be quieted by attaching a vehicle muffler to it.

So I did some investigating and this is what I discovered.

I initially went to speak with one of my friends who has spent the last 27 years working on car exhaust systems.

He’s also worked on a number of generators, repairing minor engines.

I felt he’d be the most qualified person I knew to ask these kinds of questions.

I asked him whether a vehicle muffler could be used as a silencer on a generator to make it quieter.

He explained that the motor and numerous revolving elements of a generator provide the majority of the noise.

He said that before spending time travelling to the scrap yard and adding a second muffler to the generator, all you need to do is put on a thick leather glove to protect yourself from being burned.

Take an old cloth and place it over the generator’s muffler outlet.

Wait a few seconds to observe whether the noise levels have changed.

Unless the muffler is toast and not performing as it should, there won’t be much of a difference in terms of noise.

He concluded our chat by encouraging me to construct or purchase an enclosure for the generator, as I had previously said.

He simply advised me to remind everyone to make sure the generator has adequate ventilation so it doesn’t overheat.

Installing a Generator Muffler on a Car

That was his perspective, however let us mention that when you hold the rag on the end of the muffler, you can hear a change in the amount of noise the generator creates.

It’s time to put an automobile muffler to the test.

The worst-case scenario is that it doesn’t make a significant difference, and you return the automobile muffler and call it a day.

Make sure you measure the exhaust tip of the muffler so the car muffler fits without gaps.

If there are any openings where noise may escape, the new muffler will be rendered ineffective.

It’s not difficult to install a larger muffler.

Only a few tools, clamps, and exhaust flex tubing are required.

Naturally, welding the right pipping that came with the muffler would be preferable.

However, if you can make the connection between the two mufflers tight enough so that there are no gaps, you should be OK.

Step 4: Using Plywood Boards to Muffle Generator Noise

Shielding the noise from your generator with sheets of plywood is one of the quickest and cheapest solutions to lower the decibel levels.

You may minimize the noise level by at least 10 dB by placing plywood sheets around the generator.

The ability to reduce the generator’s noise by ten dB will make it considerably more pleasant in a neighborhood setting.

You will need a couple sheets of plywood to complete this project.

Even fragments of plywood big enough to stretch beyond the generator would suffice!

Then, in the form of an enclosure box, you’ll place them against the generator.

The noise from the generator will be deflected towards the ground by this homemade plywood cage in the form of an A-frame.

This allows the noise to be contained and absorbed into the ground instead of being directed at your surroundings.

Step 5: Position The Generator’s Exhaust Pipe Away From Your House.

If relocating the generator further away from your home proves too difficult, there are still alternatives to reduce noise levels.

One simple solution is to turn the exhaust pipe away from your home, which in certain situations might be the main source of noise.

Sound waves generated by noise will go in the direction it is facing, as you can surely imagine.

When compared to having the exhaust directed straight at your home, making the sound waves flow away from your property may make a huge impact.

Step 6: Place The Generator Far Away From Your House.

We all know that the more away you are from a noise source, the less you will hear it; apply the same logic to a loud generator.

If you live in a rural region, it’s easy to keep your distance from the generator.

In contrast to an urban development, the dwellings are not as close together.

At a distance of 20 feet, a typical generator will generate between 70 and 80 dB.

The noise is loud enough for you to hear it clearly at 80 decibels.

You may relocate the generator farther away from your home by utilizing a lengthy extension cable.

If you have a separate garage or a storage shed, you could even relocate the generator behind one of these structures.

You should be extremely pleased with the results if your extension cable is long enough!

Step 7: Store The Generator In An Outbuilding.

If you have a long enough extension cable and the storage shed is near enough to your house, you could put it there.

When doing this, there are two things to consider: the echo and the fumes.

  1. The echo; If you put the generator in a reasonably empty shed, the sound waves will bounce about on the empty walls, causing a large quantity of echo. Placing acoustic panels on the walls and ceiling within the shed is one way to prevent echo. The sounds won’t reverberate this way, and it’s a cheap method to make use of a large sound box.
  2. Heat; since I reside on the extreme eastern tip of Canada, where it is normally well below freezing when the power goes out due to a snow or ice storm, I never have to worry about an overheated generator. If you’re worried about the generator overheating, you may simply install a fan inside the shed to keep it cool. Battery-operated fans may be found for a cheap price on the internet.
  3. Fumes; on either end of my modest storage shed, there are two small circular vents. I believe the vents are around six inches in diameter, which should be sufficient to handle any fumes from the generator. If you don’t have any ventilation, you may join a muffle type hose to the current muffler’s end and have it exit the barn via a tiny door opening or, better yet, a hole in the wall designed particularly for this pipe. You may always use a thick piece of rubber to patch the hole and reuse it anytime you need to operate the generator.

Step 8: Sound Absorbing Mat

Not all of the loud noise coming from the generator comes from the motor and moving elements; noise might also originate from the generator’s vibration.

Place the generator on top of a large piece of sound-absorbing mat to absorb the vibrations and, ideally, reduce the noise level by a few decibels.

When my pool pump was placed on top of a cement block, I utilized a sound absorption mat to make it operate considerably quieter.

By following the link, you can get all the details on what I did to decrease pool pump noise.

Step 9: If The Generator’s Muffler Is Faulty, Replace It.

You could have a malfunctioning muffler if you’re stuck with an older generator that sounds a lot louder than it used to.

Take your generator to a small engine repair to examine whether the muffler needs to be replaced.

It’s also possible that something is amiss with the engine, causing the generator to be louder than it should be when it’s running correctly.

This may not be worth the money if you just have a cheap generator.

However, some generators are worth thousands of dollars, so replacing a few components may be the best option for resolving this issue.

Step 10: Installing A Generator Silencer

I’ve already discussed many sorts of silencers, and some of them operate as indicated.

So I did some research and attempted to locate a similar sort of suppressor manufactured particularly for portable generators.

There are a handful on Amazon that I’ve seen other people suggest, but based on what I’ve seen in the Amazon review area, I’m not even going to mention that piece of garbage!

I did come across a couple of generator silencers that would assist to mitigate some of the noise.

The Silencer I’ll be discussing is from GenSilencer.

Generator silencers are manufactured by GenSilencer for a variety of generator sizes and brands.

I could provide an Amazon link, but it’s much better if you go to their website and search for the silencer that will suit your generator properly.

Gensilencer’s silencers are simple to install and come in a matt black finish.

The fact that these silencers come with a 1-year warranty and a 30-day money back guarantee is an excellent argument to choose them.

You may return it if you don’t hear a difference before and after installation.


If noise is your major issue, my best advise is to get the quietest generator you can locate.

It seems a little useless to try to remedy a noise issue that may have been avoided.

The latest varieties of inverter generators, on the other hand, are the quietest generators.

Inverter generators are more expensive than traditional portable generators.

I recommend the Honda EU2000i if you need a quiet generator for camping.

According to Amazon, this generator is the best little portable generator available.

The Pros include the fact that it is exceedingly silent, which is most likely why you are reading this post.

When empty, it weighs just 46 pounds, making it simple to transport about a campground.

Honda’s EU2000i generators are also quite efficient, running for around 8 hours on a gallon of gasoline, so you won’t have to keep a lot of gasoline in the RV.

The only drawback I can think of with the Honda EU2000i is that it only has 2,000 watts of power.

If you attempted any of these 10 ways for making a generator quieter, please let me know in the comments area.
