Power outages can be very annoying and frustrating. Aside from stopping you from doing your routine chores, it can actually deprive you of basic amenities such as lighting, air conditioning and sometimes heating. As trivial as that might be, you should know that accidents can happen during a power outage.

People who do know that a simple power outage can lead to serious problems will prepared for it by buying a generator. Generators are very important device especially when it comes to making sure that you will still be able to have electricity in remote areas or whenever there is a power outage.

This equipment is vital for families that need to operate medical devices at home as well as for families that have children or elderly people. Unfortunately, generators can cause a lot of noise and it can easily disturb neighbors. If you want to use it in urban areas, follow these steps so you can make it run quietly.

Things You Need To Prepare

If you want to make sure that you can lower the noise being produced by the generator, you can actually opt to buy quiet mufflers or quiet generator boxes. Unfortunately, you should understand that in most cases, the quiet mufflers will only be able to lower the noise by a couple of decibels.

Most commercial generator boxes are also very expensive and they cannot actually cancel out all of the noise produced by the generator. If you want to make sure that your generator will not be too loud, you can also opt to buy expensive models that have superior housing.

But if you already have an existing generator and you do not want to spend a lot of money on expensive commercial products, I highly recommend that you buy the following materials. This method will allow you to make your own generator housing that can make your generator quieter.

1. 2 X 4 Wood

2x4 wood

This will be used to make the frame of the housing. Depending on how big your generator is, you might have to use a couple of pieces of wood. You can also opt to use a bigger sized-wood if you want to. You can also use metal to make a frame but it might not be as effective in dampening the sound.

2. A Sheet Of Plywood


This will be used to cover the walls of the housing. You can also make use of spare wooden planks or boards so you can save a lot of money. You can also opt to use other pieces of wood for as long as you can put them tightly together to make the exterior of the housing.

3. Quiet Boards


This will be used to dampen the sound of the generator from the inside. This type of board can be bought in hardware or specialty stores. If you do not have it, you might be able to use Styrofoam or a corkboard but they might not be as effective as the quiet board.

4. L Brackets

l bracket

This will be used to hold the frame together. If you do not have any, you can simply cut the wood into the correct angles so that you can join different pieces together. You can also use smaller pieces of wood to keep the longer pieces in place.

5. Great Stuff Foam

stuff foam

This will be used to seal the crevices in between the pieces of wood so that the noise will be locked-in. If you do not have any of this product, you might be able to use caulk or glue sticks instead.

6. Screws


This will be used to lock-in the L brackets. If you do not have any, you can use nails to keep the pieces together. You can also use wood glue or high quality bonding products that can be used to keep both the metal and the wooden parts together.

How To Quiet A Generator In 4 Simple Steps

Step 1: Take Measurements

You need to plan the housing properly by taking precise measurements of your generator. You should try to make the housing a bit bigger so that the generator can easily fit inside and so that it can also be taken out with ease.

Step 2: Make The Frame

Now that you have the proper measurements, you can then move on to cutting the 2 X 4 wood to make the frame. Use the L brackets to keep the pieces together and make sure that it is screwed in place properly. The frame should not be loose and it should feel very solid.

Step 3: Put The Exterior

put on the exterior

Cut the plywood to the correct size and screw the pieces on to the frame. There is no need for you to make a door for the housing since it will simply be placed on top of the generator. Make sure that there are holes on the side of the housing to allow the air to circulate and so you can easily plug into it.

Step 4: Make The Interior As Sound-Proof As Possible

Make The Interior As Sound-Proof As Possible

As soon as the exterior is finished, you should then cut the quiet boards to the right size and carefully screw each piece inside the housing. Use the foam to seal the cracks and crevices in between the pieces of wood and also in between the pieces of quiet foam.


Generators, especially the cheap ones, are known to be very loud. Using them in urban areas can lead to complaints from your neighbors especially if you try to use it throughout the night. If you want to make it run quietly, you can opt to buy a quiet muffler, or a commercial generator housing.

Unfortunately, these products can be quite expensive and they are not known to work very well. If you want something cheap that can help minimize the sound that your generator produces, I highly recommend that you try to make your own one instead using quiet boards and foam.
