A generator is an essential device that powers your home. When storms and floods, heavy rain, snowfall, tornado, … cause power outages, generators become more important than ever. you will have the right to use the mains immediately necessary to maintain daily operations of his family. In these cases, you need a generator. However, it is too noisy. What if you know how to build a soundproof generator box?
Generators are an effective way to power your home during a power outage, however, they can make a lot of noise. Nobody wants to hear the noise coming from the generator while it’s running; it becomes very troublesome. Its loud noises can be really distracting and can be a source of serious discomfort for your household and the homes around you.
There is a way you can reduce that loud, jarring, headache. If you build a soundproof generator box, you can enjoy the power saving request that machine offers without having to listen to audio that flies unbearable.
However, not every generator owner is aware of the method of using a soundproof generator box. If you have never heard of this method or do not know how to do it, please read the article below, we will show you how to build a soundproof generator box.

7 notes before building soundproof generator box
- Making a generator soundproof box is not difficult to do. But you need to follow these 7 guidelines to make it more effective.
- Secured building a box that can be easily assembled and disassembled for better storage.
- It must be able to absorb at least 55 to 65% of the noise.
- It must be airtight from all areas so the noise cannot be emitted.
- Be sure to leave holes or air intakes for cooling or its parts will be damaged.
- The soundproof box must also be waterproof so you can use it when it rains.
- It should also be modular so you can easily transport it anywhere.
- You must consider the dimension, the materials, and the insulation for your quiet generator box.
Materials Needed To Build A Soundproof Generator Box
Before we get into the details, let’s take a look at some materials that you may not be aware of:
MDF – the main material that you will use to make the box
MLV – This is the first layer in an in-order soundproof generator box
Foam mat – another layer you use in a soundproof generator box for sound insulation
Green glue is used to glue the edges down and is another soundproofing tool
Ventilation pipes are used to create supply and good airflow generator soundproof box
To build a soundproof generator box, we need the following materials:
- Measuring tape
- Paper and pen
- Right angle ruler
- MDF board
- A saw
- Screwdriver and hammer
- Foam carpet
- Green Glue
Keep in mind that you won’t be able to perfectly insulate your generator as the box needs ventilation holes to keep the generator from overheating. These holes will make some sound from the generator coming out of the box, but will certainly be quieter than the sound from the generator.
Instructions On How To Build Your Own Soundproof Generator Box Step By Step In Detail
Step 1: Measure the size of the generator
The first thing you need to do is measure the generator so you can make sure you build the soundproof box with the right size for it.
Use your ruler to take measurements and record them.
Please note adding a few inches to your measurements for the materials we will use to insulate your box walls.
Focus on measures. This is extremely important. If you mess up the measures, you probably won’t have enough space for the box’s rest.
Please note: measure two or three times before you start cutting
Step 2: Cut the MDF board
Now cut the planks out based on the measurements you recorded with a saw.Use your circular saw or table saw, whichever type you are using, cut the plank out.
Make sure not to cut any more sides than you should.
If you are unsure about them, first mark the dimensions on the fiber board with a ruler and pencil, and then cut them accordingly.
Next, cut the MDF boards according to the generator’s size using a table saw or disc saw.
After cutting, label each piece accordingly so you know which pieces will need to be positioned during construction; the ceiling, base and sides of the box.
Make sure you are concentrating on the labels and board measurements you made earlier.
Step 3: Create ventilation holes
Generators must be ventilated for two reasons:
They run on gasoline, so you need to have exhaust vents to get out of the box.
They generate a good amount of heat. The exhaust system is required to avoid overheating.
To create ventilation holes, measure the size of the ductwork you purchased and cut two round holes on the MDF board to match the size of the tube.
Use the ventilation duct that you purchased for this project and measure its diameter. Then, on the fiber board, mark the two circles.
1. The first circle should be placed at the top of your box. You have to place the circle near one side instead of in the middle of the board.
2. The second circle should be placed on one of the planks’ mean side face. Mark the circle on the other side from the position of the top hole.
Once everything is marked according to the instructions, put the wall on the table, the ceiling set in the middle with the remainder of the wall around it.
Step 4: Add insulation MLV
The key to minimizing sound are material layers and free space. The more layers, the more the sound will be blocked.
Vinyl is one of the best materials for the purpose with good sound insulation. MLV is a heavy but soft vinyl sheet, usually saturated with small metal particles.
Perform the measurements of your fiber boards again and use them to cut mass loaded vinyl that you have in hand.
Now paste the material you just cut to the inside plank average fiber density. Metal particles which increase the mass of vinyl, increase the quality of its sound absorption.
The MLV is the first layer you need to install when building a generator soundproof box.
Accurately measure each MDF board and then cut an MLV piece of the same size as each plank. Use Green Glue to fix the MLV to the inside of its respective MDF board. Apply adhesive to the edges of each MLV piece to ensure that they are firmly attached to the MDF.
Step 5: First layer sealing
Time to apply the Green Glue that you have prepared. Widely applied, especially on edges. The edges of the MLV insulation can be difficult to stick down properly, so you will want to use the green glue to solve this problem.
The purpose of this step is to ensure there are no gaps or holes for good sound insulation.
Of course, if you have a little regular caulk that’s okay, but like plywood and fiberboard, it will be more efficient.
After using the glue on the first layer, let the glue dry before moving on to the next step.
Step 6: Install the foam mats
Porous rugs are known to have a soft surface and that’s what makes them so useful for sound insulation; they keep the sound from being reflected.
For the second layer, mark the measurements on the foam carpet, cut them out accordingly and place them on top of the vinyl layer.
Use Green Glue to glue the edges and make sure no sound comes out.
Next, installation of carpet foam sound absorption. Cut the rug so they are the same size with the MDF panels and will be used for ceilings and walls of your generator box.
Use blue adhesive, attach the foam mat on the inside of the plate MDF respectively so that they are positioned directly on MLV. Once in position, use the Green Glue to fix the edges of the foam and add audio on the fiberboard.
Step 7: Assemble the parts to form the box
Let the Green Glue dry completely. After drying, assemble the soundproof box. Placing the MDF panels will act as the sides of the soundproof generator box around the MDF panels that will act as the ceiling.
ensure that the walls are placed in the proper position. Screw those plates into position. Another thing you can do to ensure that you’ll have easy access to your generator is to install some hinges.
To narrow the gap between the top and the side of the acoustically-insulated generator box, we suggest applying Green Glue along the edges of each MDF before screwing them in place.
Since Green Adhesive is a means of sound insulation, it will help block any gaps where sound might escape, thus improving the sound insulation of your generator box.
Remember that you will need to adjust the vents in that case, but that’s just a small adjustment and ability to perform a much better approach to what you need.
Step 8: Installing the ventilation duct
The uninterrupted noise of a generator is of high importance when it comes to the health and normal operation of the generator.
That means you’ll have to give it a good airflow and supply for the best productivity.
Without enough air, it can start to overheat and release heat to potentially catastrophic circumstances.
So, even if you use soundproof portable generators, the same rules apply – and you should always think about ventilation as well as heat dissipation.
Burning cannot be achieved and the risk is very high. And we don’t expect that to happen to your generator.
Once you have installed the vents on your DIY generator housing, use multiple vents. Be sure to use more of it. As much as possible.
Remember: sound waves have a straight path as they travel.
If you use too many bends when placing the vent, more noise gets stuck and lost in its wrinkles.
Place the tubes in the holes that you prepared in step 3 and make sure to screw them in place.
Step 9: decoration for soundproof generator box
For a bit of entertainment and to give your soundproof box a unique look, paint the color you have prepared and decorate it a bit.
In addition, you can paint the outside of the box with soundproof paint to increase the level of sound insulation.
For portability, you can also install a handle at the top of your soundproof box.
Use a piece of fiberboard inside the soundproof box as a support for your handle and twist your handle to that point.
Congratulations! You have successfully made your own custom portable soundproof box for your loud generator.
Tips to keep your generator quiet
Above are some of the 5 important tips that you should keep in mind when building a soundproof generator box.
Don’t buy any heavy generators if you don’t have a need. Because the more power a generator has, the more noise it generates.
Make sure not to point the exhaust pipe of the box towards you. This will help reduce the noise you hear.
If possible, keep the generator at least 20 feet away from you. For this, you need to invest in a long, high-quality power cord.
A solid hard surface increases vibration and noise levels. So if you have any soft surface then put your generator on it.
Use this cover with your generator to reduce all the annoying noises.
A few things you need to know about noise and generator
The Reason Why The Generator Makes Noises
Generator is a device that converts mechanical energy into electricity, depending on the fuel used, the machine is classified into 2 types: gasoline generator or oil generator.
Generators as well as other types of cameras powered by internal combustion engines emit noise and vibrations.
In which the noise generated by the generator can reach 100 dB (A) or more without sound insulation or noise protection. According to the researchers, a person exposed to noise over 85 dB for a long time (over 8 hours) has a higher risk of hearing loss.
Therefore, it is very important to reduce noise.
There are many parts that make the machine make noise, as follows:
- Due to the engine
As mentioned above, the generator uses the principle that the internal combustion engine relies on the movement of the pitton to generate energy. Specifically, the principle of how the generator works, you read more.
Because this is partly the cause of the noise in the generator. Depending on the size of the different engine, there will be different noise levels, the louder the engine, the louder the noise, and vice versa.
- Due to the cooling fan
This fan causes the air to move at a high speed, and passing through the engine part and the radiator makes a noise. You are 1m away with a noise range ranging from 100 dB (A) to 105 Db (B),
- Due to the use of an AC machine
The alternator works on the air cooling mechanism and friction on the brush causes noise. This noise ranges from 80 Db (A) to 105 Db (A).
- Due to electromagnetic induction
The current fluctuates in the winding system of the machine. They cause mechanical motor noise from 80dB (A) to 90 dB (A).
- Due to exhaust gas from the engine
Some generators do not have a silencer installed in the exhaust manifold which will cause noise in this part. The noise will range from 120 dB (A) to 130 dB (A) or higher.
- Due to the chassis gas structure
Different parts, structure of the generator frame will cause different mechanical vibrations. They will generate radiation in the form of sound and make a powerful noise.
Effects of noise on human health
Most of us have a tendency to think that noise has no effect on our well-being.
But sadly, it has a negative effect on us.
Excessive noise exposure has been shown to cause a number of health problems, including stress, low concentration levels, poor productivity, hearing loss, and difficult problems. communication, lack of sleep, and many other problems.
According to a report published by WHO in 2011, at least one thousand years of healthy life are lost each year in Europe due to noise pollution.
Other forms of pollution are decreasing while noise pollution is continually increasing, the report’s authors report.
This is really interesting, because it seems that the sounds we don’t even perceive when we listen to them are the ones that affect us the most, such as during our sleep. .
The human ear is one of the most sensitive parts of our bodies and never rests, it means that we tend to hear a lot of noises and sounds in the lives of us without really being awake to hear them.
although we don’t know about hearing them, the ambient noises of traffic, neighbors, or whatever, are being processed by our bodies and reacting in different ways through the wires. Nerves travel throughout all parts of the body and the hormones that our brain creates.
Sound is an important part of our lives that, unfortunately, cannot be eliminated. However, when sound becomes noise, it can negatively affect our mental and physical health.
The reason I’m giving you attention is that we need to realize that noise pollution is a serious health problem and try to find practical ways to control it.
What does soundproofing mean ?
Until the power is exhausted, the sound waves are non-stop and will continue.
Sound insulation primarily disrupts sound waves as it relies on layers, resulting in sound reduction.
There is a common misguided opinion that soundproofing and dissipation are the same thing.
In fact, sound absorption is one of the properties of sound insulation.
Sound insulation is basically the process of creating sound solutions to reduce, absorb, or diffuse sound waves from entering or leaving a particular room or area.
Sound absorption is the application of products that absorb sound waves and prevent them from bouncing back in rooms or areas.
Here are four basics you need to know about sound insulation.
Heavy and thick solid materials will help impede sound. To test this rule, simply try adding volume to the wall using heavily loaded furniture and vinyl.
Damper is achieved successfully by using something known as damper compound, such as Acacia Xanh. It is the most effective way to deal with noise.
For active damping principle, apply a damping compound you choose between two hard panels, such as plywood, and screw them together.
When the sound is transmitted to them, it will stimulate the shear forces between the hard plates to create friction and thus, converting sound energy into heat energy.
Basically, decoupling is either separating or creating a void. In the case of sound insulation, you are aiming to create a gap between the plywood and the wall of the room or area you are working in. Creating gaps disturbs sound vibrations, which in turn reduces sound.
The most suitable sound insulation material for separation will be elastic channels. These effectively affect the noise, because when the sound travels to them, it vibrates between the channels, preventing it from passing through the wall.
Having mentioned that last rule, I’m sure you know well that the most effective material for absorbing sound is soundproof foam.
Every principle of the four principles separate activities, but ultimately, they complement each other, which means combining all of them together will bring you the best results.
Is Sound Insulation An Effective Way To Decrease Noise?
According to an article published by Life + Health Network, there are five methods to reduce noise pollution and sound insulation is second on this list.
The first thing on the list is to turn off all of our electronic devices, but I guess this will be difficult for us.
Next on the list are their tips for noise removal.
Did they try to keep you with relatively pleasant sounds such as running water or turn on the fan. An alternative solution is proposed to hang a wind chime somewhere close to you often hear the pleasant music.
The fourth method to reduce noise pollution is to simply wear some earplugs. Earplugs will also provide you with a better night’s sleep. Just make sure you’ve set multiple alarms and they’re all big enough!
The ultimate way is on the move! If a viable option is for you to move from your current home to another house a little further from the city, do it.
In Conclusion: Building A Soundproof Generator Box Now Is As Easy As Turning A Hand
