How To Quiet A Generator – Best Tips In 2020

When camping, there’s need for a generator to provide electricity to carry out activities like charging of phones, charging portable fans and all.

However, some people find it difficult to purchase one because of the noise produced by the generators. This makes them go for dry camping – the type of camping where an individual survives without essential amenities like electricity and water.

Even some those have these generators for their camping have serious issues whenever the generator set is put on because of its noise. Mind you; noise pollution reduces the alertness of the camper to hazards that are close by.

This issue makes some people consider buying a new one which could be quieter, but the worries of the expenditure get to them, and they change their minds.

A dilemma, isn’t it? To sort out this dilemma, one thing you can consider is to quiet the generator. It saves money, eliminates noise pollution and gives you the desired peace of mind.

Moving on, I have some tips on how to quiet a generator, but before I step into the tips fully, I’ll like us to consider some factors that can affect the noise produced by a generator. As the saying goes, the problem is best solved when taken out directly from the root. Here are two significant factors that affect noise production by generators:

Generator’s location

There’s no two way about it, if your generator is placed very close to you, the noise it will produce will be twice its magnitude if it’s away from you. That said, your discretion is required in placing the generator at a spot that’s not too near from you and not too far as well. I had to point out the discretion aspect, so you don’t end up losing your generator due to possibilities of theft if it’s far from you.

Type of technology implemented

The kind of technology the generator was crafted in determines the amount of noise it gives off. The generator could either be conventional, silenced or an inverter generator. Inverter generators generally produce less sound because of the sophisticated technology used in their production.

They have the capacity to detect less power load; as such their engines throttle back thus, minimizing noise and even fuel. Silenced generators, on the other hand, are built with an acoustic cabinet which soundproofs the noise. However, it’s not as noise-free as the inverter generators.

The conventional generators, just as the name sounds are the oldest and most used worldwide amidst the three. Its system of operation wherein its motor runs at a speed of 3600 rpm causes it to be the noisiest.

Now that you’ve come into cognizance of these factors, I’ll share some tips on how to quiet a generator. Here are some helpful tips:

Changing the Generator’s Muffler

The use of a bigger quiet muffler to replace the original muffler in a generator’s exhaust tube plays a vital role in reducing its noise.

Avoid Positioning the Generator Too Close to the Camping Site

This tip isn’t far-fetched. It’s important because it will limit the amount of noise that gets to your dwelling place.

Too much noise is terrible for the camping expedition. One of the primary reasons for going camping is having time to relax and to think clearly. So, noise of the generator being too close can limit that.

Construct a Soundproof Box

The most effective means of making a generator quiet is to build a soundproof box. Building a soundproof box doesn’t need too much professionalism, but it requires the proper tools and measurements to give it a feel like the commercially produced acoustic cabinets. First and foremost, the devices to be used have to be complete.

The tools which will be required for this soundproof box includes; One sheet of 4×4 plywood, rubber sheeting, nails, screws, rivets, circular saw, acoustic caulk, vent and ventilation ducts, cooling fan, glue, exhaust tube, measuring tape, hammer, and screwdriver.

After getting the required tools, the next step is to take measurements of each side of the generator. Having done these, you add at least 8 – 10 inches to each side to create enough ventilation for the generator.

Afterward, you assemble each side using glue or hinges. If the generator is only for use as a backup, and doesn’t require transporting, the adhesive is advised. However, if your use of the generator entails moving around like camping, hinges will be preferable to aid ease of transport.

Ventilation is the next phase of the construction. Make use of the circular saw to cut three holes into the box. Ensure the holes are the sizes of the vent and the cooling fan. Then, fit in the air vent and cooling fan properly into two boxes leaving one box empty.

Insulating the box with rubber sheeting comes up next. The rubber sheeting has to be glued, and then caulked to seal the edges.

The second to the last step is the attachment of the exhaust. Here’s where the empty box comes into play. An exhaust hose is passed through the box and fix onto the generator muffler.

The last step is to put the soundproof box on the generator. Caution has to be taken to ensure that the exhaust hose is directed outside to avoid the generator re-absorbing the fumes. Another point of concern is to point the exhaust pipe away from the direction of the rain. This will prevent water from getting into the generator.

Purchase a Soundproof Box

Well, if it seems you the steps above are a bit difficult, you can purchase a commercially produced soundproof box. All the same, you get to enjoy the same benefits, and even have better soundproofing. However, then, you have to let off some cash.


A noise-free camping expedition is very soothing. So, it’s essential to make it as quiet as possible. On the final note, you can also consider getting quiet generators. The quietness and convenience make every penny worth it. All the same, apply these few tips and do well to give us feedback. Don’t hesitate to share other successful methods you’ve tried out.
