How to Make a Power Generator Quiet

I love my power generator. It can allow me to get a consistent flow of electricity. This makes generators the perfect tool for camping, or to provide power to your house during a blackout. However, it can often be quite loud. I wanted to find a way of quieting it. Here are some of the tips I came up with.

Position the Exhaust Pipe

When setting your generator up, it’s important to consider where you are going to put the exhaust pipe. This will produce the most heat. More importantly, it will make the most noise. If camping, you’ll need to make sure that the exhaust is facing away from your campsite. In some cases, you might be able to position the exhaust into the air.

Put the Generator on a Soft Surface

Where you choose to put the generator can also have a big impact on how much noise it will make. When you put it on a hard surface, like concrete, you’ll be amplifying the vibrations. Because of this, you should try to find a softer surface. This will help the vibration dissipate. If you’re going camping, you might want to put it onto the grass. If you’re at home, you can get rubber feet for the generator.

Place the Generator Far Away

If you’re going camping, you’ll have to decide where you want to put the generator. It’s often a good idea to put it as far away from the camp as practical. The farther away it is, the less you’ll be able to hear it. There are a few things that will limit how far away the generator will be. For example, the length of the cord.

When deciding where to put the generator, try to put some cover around it. For example, if you’re camping, put the generator beside a log. If in your home, try to put some thick walls between the generator and your family areas. These will absorb the sound produced by the generator.

Replace the Muffler

If you’re searching for a more permanent solution, you might want to try replacing the muffler. This is one of the loudest parts of the generator. By replacing this, you’ll be able to reduce the sound by about ten decibels.

While replacing the muffler on your car will be easy, it might be more complex to replace the muffler on your generator. Before buying one make sure that it will be compatible. After you’ve purchased the right muffler, you’ll need to put it on the generator. The way you’ll need to do this will depend on the generator that you purchased. In some cases, you will need to get the generator custom-made. This will ensure that it will fit properly. This video shows how you can get creative when making your muffler.

If you don’t want to buy a new muffler, there is an alternative. You can use a water bucket. Take a piece of hose and place the end of it into the water bucket. This will funnel the sound into the dense water, which absorbs the sound, quieting the generator. If you’re doing this, be careful that the water can’t snake its way back into the generator. There are ways to prevent this. First, put the generator higher than the bucket. You might also want to put a small hole into the house. This will give the water an outlet.

Build a Baffle Box

One of the most effective ways to silence a loud generator is by building a soundproof enclosure. This is known as a baffle box. While this sounds technical, it doesn’t need to be a baffling project. All a baffle box is a wooden box that will fit around the generator. This will absorb the vibrations of the generator, making it sound a lot quieter.

You might be able to find a baffle box made to suit your generator. This will save you the time of making one yourself. If not, don’t worry. It’s a simple project that you should be able to complete in an afternoon. This video goes into more depth about how you can build your box.

Remember that you need to include holes for the air. This will stop the generator from overheating.

Maintain the Generator

One of the most overlooked ways to quiet a generator is by keeping it maintained properly. This will ensure that it’s working properly. Regular maintenance is the key to keeping your generator working for a long time. There are a few maintenance activities that you might want to perform. First, you should check all the bolts have been tightened properly. Because of the vibrations, some of them might come loose over time. When this happens, they can be amplifying the sound of the generator.

Another element that you might want to check is that the machine has been lubricated properly. Grease up the bearings. This will also protect against power loss, ensuring that your machine is as efficient as possible. You must try to avoid over-greasing.

Buy a Quieter Generator

Though these tips will be effective, you might still be annoyed by the amount of noise that your generator is making. At these times, you might have no other choice but to purchase a new, quieter model. When you’re buying, the amount of noise that it makes should be listed in the product specifications.

It’s also important to look at the size of the generator. Though bigger models will produce more electricity, they will also be louder. Also, the type of fuel might affect how much noise it makes. Be sure to read multiple reviews before making your decision. By doing this, you can be confident that you’ve picked the right model for you.


Hopefully, I’ve been able to help you quiet a noisy generator. Most of the items on this list won’t cost you anything, so you can get results quickly. This will allow you to enjoy the benefits of the generator, without needing to listen to the vibrations.
