How To Make Your Generator More Quiet

For anyone that lives in close proximity to a power plant or generator, you know how disruptive they can be. But did you know there are ways to make your generator quieter? Here is what we recommend!

Goes into the post content with tips and tricks on how to reduce the noise of your generator.


Problem: Generators are great for powering up your home during a power outage, but they can be incredibly loud. This is especially true if you live in an area with strict noise ordinances or have close neighbors that do not appreciate the sound of a generator running at night.

Agitate: No one wants to sleep next to a noisy generator, and no one likes being woken up by the sound of their neighbor's generator either! In fact, many people who rely on generators as part of their emergency preparedness plans will not even use them because they are too noisy.

Solution: We have been there too! That is why we created this guide full of tips and tricks for making your generator quieter so you can enjoy peace and quiet while still having access to clean energy when you need it most.

How to make your generator more quiet

1. Make your Generator Soundproof Box

The first option you have to make a generator quiet is to build a soundproof box. This solution works best if you do not need to carry the generator anywhere because the box makes it heavier and harder to handle. If you plan to use a generator while camping, consider another option to make a generator quieter.

Steps to build a soundproof box

  • To make a generator soundproof box and add insulation, take the size of your generator and add a few inches on the sides
  • Cut the pieces out of the MDF. Obviously, you will need 6 pieces, one on each side, so make sure you have enough MDF to complete the project. Use the right protractor to make sure your measurements are straight and accurate.
  • Next, make a generator's exhaust pipe. Measure the diameter of the exhaust pipe to get the right size. Cut a ventilation duct on the ceiling panel. This should end at a corner. Cut the remaining hole in one of the wall panels and the hole should be in the opposite bottom corner so that they are almost diagonally.
  • Then add a layer of bulk-loaded vinyl to the inside of the panels. This should be glued directly to the MDF. Use Blue Glue to glue the edges of each piece of heavy-duty vinyl to ensure they are glued down properly.
  • Add a layer of foam mat. This does not necessarily help with sound absorption, but aids sound reflection, making it harder for sound waves to bounce inside the box.
  • Assemble the box, secure the panels together with screws and Green Glue as needed. Mount the lid with hinges for easy access when the generator quieter is inside.
  • Finally, add the air vents and seal with Green Glue. Use several exhaust pipes to ensure the generator is well-aired. Placing a bend in the duct will help deflect the sound waves as they travel down the tube.

2. Move the generator further away.

The next thing to keep in mind when considering how to quiet a generator, besides building a Soundproof Generator Box, is the distance you place it from your campsite.  This is one of the most important factors in ensuring to make your noisy generator quieter while camping.

The distance you can place your generator quieter from your campsite will depend on a few different factors. Whether you are camping on a campground with specific campsites or on open land while boondocking is the first thing to consider.

For example, if you are camping at a campground that offers smaller-sized camping spots, then obviously, you need to keep your neighbors in mind.  You do not want to bother your fellow campers with the generator noise from your generator quiet by placing it closer to their campsite.

If you are camping in a place where there are no other people around, the most important factors to consider are the length of your extension cord and how much you want to hike. The farther you place your generator from your camping site, the quieter the generator will be.

Most generator brands will display what the decibel rating of that particular model is. These decibel ratings are measured at a distance of approximately 7 meters from the generator quiet in operation in most cases. So a general rule of thumb is to keep the generator at least 20 feet away from your camping site if you want to operate within that decibel range.

If you have the space and lack camping neighbors, then investing in some heavy-duty extra-long extension cords will allow you to place your portable generator as far away as you would like.

By keeping the generator at least 20 or more feet away from your camping site, you can vastly cut down on the generator noise and focus on enjoying the outdoors.

3. Make a baffle box for your generator quieter

Build a quiet box-the baffle box for your generator is very similar to the soundproof box suggested above, and if you know about soundproofing, you know what a partition is. If not, then all you need to know is that the baffle box is designed to reduce the overall airborne amount of noise.

To build the baffle box, you just need to follow the instructions for building the soundproof box but leave only the bottom. This means you will not have to hinge on the lid, as the box can only be placed on the generator.

4. Buy a Generator Muffler

The purpose of quiet a generator muffler is to muffle the sound, so it makes sense to use this technology. If the muffler currently installed on your generator does not fit very well, simply buy a larger generator's muffler.

This will not make a massive difference to the overall generator noise, but the amount of noise pollution comes directly from the exhaust. This option should be combined with some other options to improve overall efficiency.

5. Place the generator on a soft surface to quiet a generator

Another important factor to consider when looking for ways to quiet a generator is the surface on which you place the generator while it is running. Once you have found the right distance to place the generator, you need to make sure to place the generator on a surface that can reduce noise rather than amplify it.

It is best to avoid all hard surfaces. Therefore, do not place the portable generators on concrete, wood, or asphalt as these surfaces will only reduce the noise.

Usually, if you are camping, the best and only options for turning on your generator are simply dirt or grass. These are both great solutions as a surface on which to place your generator. Both of these will absorb and dampen the sound produced by the rumbling generator.

If you are in a situation where you do not have a softer platform to put your portable generators on. Rubber feet are a great solution here. Rubber feet mats are generally made of rubber and help to calm the vibrations and noises emitted by household appliances.

6. Set up sound deflectors

If your generator is kept in an occult space, such as a shed or outhouse, and you do not plan on moving it soon, the sound deflectors can certainly make a difference.

The important thing to keep in mind here is that this will not soundproof anything. The purpose of the sound deflector is to deflect the sound, which means less of a chance to reach you. Therefore, it will also reduce the overall noise in the air.

Sound deflectors are really easy to buy. Similarly, you can combine this with several other options to improve efficiency.

7. Use water as Your Generator Muffler to quiet a generator from exhaust noise

This sounds like a dangerous and counter-intuitive choice, but it actually works pretty well to reduce the noise from the generator's exhaust. All you need is a bucket of water and a hose.

Then all you need to do is fix the hose to the end of the generator exhaust and place the other end in the bucket of water.

Sound will be suppressed by water and significantly reduced noise. If you are concerned about water getting into the generator, make a small squeak in the hose. This will prevent pressure from building up.

8. Moving The Exhaust Pipes To A Vertical Position

There is a great deal of importance in the way the generator exhaust pipes are rotated.

When the exhaust pipe is rotated horizontally, they are blowing air outside, they are also blowing noise horizontally.

However, if you rotate the exhaust pipes to direct the air above the generator, the noise will also go in that direction, and produce less noise, and it will not be a loud generator.
