How to make a silencer for a generator

Generators are the perfect solution to blackouts and are routinely used in emergencies as well. That’s why they are quite vital for hospitals, schools, and other important scenarios. They can provide an adequate amount of electricity to power emergency lights and are super important for most homes nowadays.

However, that being said, one of the worst things about generators can be that they are much too loud! That’s why today’s article is dedicated to finding out how you can make a silencer for a generator at home.

Why would you need a silencer for a generator?

For human beings, all sounds and noises that come under the 70dB mark are generally considered safe! Anything above this might be dangerous and might even add to eventual hearing loss or damage in the long run.

Even when it comes to the portable kind, most generators will be over that range! This means that they can go up to 90 dB and that is not safe for human ears. This is especially lethal if your generator is the kind that will stay active all day long.

Apart from your ear health, why not consider investing in a silencer for the sake of your sanity? If you don’t get a single moment of peace especially if you are out camping, then what is the point? You might also want to consider how your neighbors feel about the constant ruckus.

While most generators will usually stay within the 70 to 90 range if there is something wrong with them this might be increased even more. These might be referring to certain mechanical issues and these must be fixed.

However, there is always the option of creating your DIY silencer at home!

Let’s look at the main steps on how to make a silencer for a generator:

1. Calculate the silencer box’s dimensions

The first act will be to figure out exactly how tall and wide the generator is. This will lay out the dimensions for the silencer box itself. You want to ensure there is quite a bit of space between the box and the generator.

This is because we will add some insulation and sound-absorbing materials as well. It might be beneficial to look at the product’s size and dimensions that the manufacturer listed. These might not be entirely accurate but will be helpful.

2. Do not forget to include proper ventilation

The next step is to make sure you don’t forget to ventilate. A generator will need a good amount of circulation and ventilation so that the airflow is good overall. Otherwise, it could prove dangerous for you and your generator as well.

3. Add in sound insulation below

You must make sure the ground beneath is properly insulated. This is where the product is in contact with the ground. So, you can add rubber sheets or mats below to ensure this doesn’t happen.

4. Improve on the Sound Insulation

Creating that insulation layer is good, but this is not enough. You should also add more layers to absorb and block out sound. You can use sound-absorbing materials such as TMS vinyl that is easily found online.

Apart from this, you may also choose to invest in adding more insulation materials such as plywood and foam. These will add vital space between the main enclosure and the generator and deflect the sound waves.

5. Finish assembling the Silencer Box

Now, all of the work is done. All that’s left is attaching all of your components. Don’t forget the top lid portion of your box. This is crucial and should be screwed on tight so no sound vibrations escape.

What are some of the alternative hacks to making a silencer for a generator that you can opt for instead?

If you have already made your silencer for your generator and still want to increase the amount of soundproofing that it has provided, here are some additional hacks:

Install away from your living space/ camping space

The first hack that you should think about the will of course work best before the generator is ever installed! Location is key with a product such as this.

This means you should preferably keep the device as far away from your home or camping spot as is possible. This will ensure that you have enough space in between to deafen out its vibrations.

Create a soundproof setting

Speaking of vibrations, in our experience, the best hack is to create a small enclosure for the generator that will absorb its noise. Of course, this will have to be properly ventilated as well because otherwise, it would be dangerous.

If the enclosure or setting is made from concrete, you can even lay down an additional rubber mat below to ensure vibrations are further reduced.

Place sound deflectors

If anyone is familiar with how sound travels through the air, they will know that the sound waves can be absorbed or deflected. This can be attained with the addition of sound deflectors in between you and the generator. These deflectors can be anything from a fence to the enclosure we talked about before.

Attach rubber feet below the generator

This is the most cost-effective solution yet! All you have to do is attach small rubber feet below the generator so that it can effectively absorb the vibrations and subsequent sound waves. These are produced when it is in contact with the ground.

In conclusion, this has been our detailed informational guide on a step-by-step guide on how to make a silencer for a generator. We have also added a list of alternatives that you can add to enhance the effectiveness of the silencer you created.

We hope that our guide has been a helpful one and you are now equipped with the right kind of information!
