How to Quiet a Generator

Have you ever wondered how to quiet a generator? Chances are, this question has crossed your mind more than once, especially if you have a rather large generator that is very close to your home for emergency purposes or if you are trying to go off the grid and you are using a generator to power some basic essentials.

Either way, you are probably trying to do one of two things. You are either attempting to refrain from calling attention to yourself or you are simply trying to keep your sanity. In either case, a generator that is running loudly fairly close to your sleeping quarters is going to prevent you from having any sanity and it most definitely will call attention to you no matter what you are doing. Fortunately, there are some things you can do to remedy the situation.

How to Quiet a Generator

The Obvious Solutions

The first solution is true in any case, but it is especially important when you have a rather large generator near your house in order to ensure that you have power even when your neighbors don’t. One of the best things you can do is place that generator further away from the house. Having one that is too close is going to make it extremely loud whenever it is operating. Typically, the larger the generator is, the more noise you have to deal with. By the same token, you will usually discover that the cheaper machines have a tendency to be much louder. If you want one that runs more quietly to begin with, consider buying a high quality machine that is designed to run quietly from the beginning.

Install a Muffler

If you still need to know how to quiet a generator, there are some other things that you can do with varying degrees of effectiveness. The first thing that you can do is install a muffler that is designed to make the generator more quietly. Make no mistake about it, these mufflers are not usually a solution that is entirely effective. In fact, they usually only have a tendency to reduce the sound level a little bit, so it may not seem worth it for you to go to the trouble to install it. If you have a generator that is already relatively quiet and you are looking for a little extra relief, this solution could work. However, if your current generator is exceptionally loud and is basically driving you crazy, it would be a good idea to look for a more effective solution.

Create An Exterior Sound Barrier

One thing that you could do is create an exterior sound barrier. This basically means that you need to put the generator behind some sort of material is capable of absorbing sound. For some people, this works very well. It works best in a situation where you have a permanent generator on your property and you have no desire to move it around. It may not work as well if you are off the grid and you have a portable generator coupled with the need to move from place to place. It would obviously be difficult remove everything each time, so it is something that you have to consider depending on your circumstances.

Build A Soundproof Box

One of the most effective things you can do is build a soundproof box. If you really want to know how to quiet a generator effectively, this is the solution. Remember, generators are louder when you put them on wooden floors or anything that is capable of transmitting sound easily. The same is true when you put them in a box made from materials that easily transmit sound. Your best bet is to use cinder blocks or something similar. They don’t transfer sound easily and they are fireproof. In addition, you should create some type of ventilation system so that the fumes from the generator can be vented to the outside. For extra protection, use a fan or something similar to cool the generator while it is running so that it doesn’t overheat.


An excessively loud generator can be frustrating, to say the least. To further complicate matters, running a generator that is too loud can create complaints from the neighbors and in a worst-case scenario, it can mean that you don’t have the safety and security of not calling too much attention to yourself. This is a prerequisite for many people that decide to go off the grid. In any case, you need to find an effective way to run a generator without making a bunch of noise. By tapping into one of the solutions listed above, you can do just that.
