How To Quiet A Generator With 8 Simple Methods 

Trying to figure out how to quiet a generator? Learn 8 fantastic techniques for lowering the decibel level of a noisy generator. Generators may be a very useful tool when camping in a travel trailer or RV.

If you are using your generator for minor tasks like charging your phone or larger ones like powering equipment, they may be quite useful while experiencing the great outdoors.

The disadvantage of utilizing a generator to provide these creature pleasures on your camping vacation is, of course, the noise it produces.

We’ll go through the top eight techniques for quieting a generator so you may enjoy a more pleasant camping vacation without missing out on the necessities.

Reasons Why Your Generator Is Louder

Noise is created by six primary sources, whether it is a household or commercial generator. Engine noise, engine exhaust, alternator noise, cooling fan noise, induction noise, or mechanical noise are some of the origins.

Sound levels vary depending on the type of generator. Standby generators or portable generators, for example, have variable noise levels. The engine block and the exhaust system are the two major sources of noise in portable generators.

A generator engine, such as the rest of the motors, generates lots of heat and requires a cooling strategy to detect overheating. Air-cooled and liquid-cooled standby generators are available. The primary distinction between the two cooling methods is that air-cooled systems are noisier and less effective. Liquid-cooled systems are silent and more efficient, but they are more costly to obtain and operate.

Another mechanical component that is producing unpleasant noise in your generator seems to be a muffler that no longer works properly. Quiet mufflers for small engines are designed to dampen machine noise. A faulty muffler may cause havoc with perfectly running generators.

Incorrect Generator Location

Whenever it comes to decreasing the sound level of a generator, the positioning of the generator is the most significant thing to consider.

The materials on which the generator is mounted are the most important factor. The noise level would increase if you placed your generator on a metal bench. As a result, avoid positioning the generator on surfaces that act as amplifiers.

Furthermore, unstable and harsh surfaces such as asphalt, wood, metal, and concrete are a no-no for generators since they increase vibrations and, as a result, noise levels. Instead, position the generator on a sturdy and soft surface, such as flat dirt. The vibrations will be absorbed by the earth as a result.

The Generator’s Energy Level

Another reason why your generator is loud is the amount of electricity it produces. Larger power sources with bigger engines and greater power are more likely to create louder noise.

The Technology Used To Produce The Generator

Any generator outfitted with modern technology is likely to be quieter. Inverter generators are among those generators that use cutting-edge technology to make generator quiet and more compact.

Furthermore, to decrease noise, those inverter generators are outfitted with sound deflectors or mufflers. Since they produce less noise, inverter generators are sometimes known as eco-mode generators.

8 Methods To Quiet A Generator

The first thing I’d want to mention is there are a couple of reasons why the generator is having issues like that, and what may be causing it to be so noisy.

As a result, there are numerous possible answers to the sounds it is making. Some of the various ways for making a generator silencer include the following:

Purchase a Generator that meets your requirements

Knowing your power requirements should be considered even before purchasing a generator. If you know what your power requirements are before purchasing, you may be able to avoid the loud generator scenario entirely.

It’s rather easy. The more energy your generator has, the more sound it will create. You should consider how much electricity you require, how much noise you can tolerate, and how much money you are keen to pay for a generator.

Some campers just need enough energy to charge their phones, iPads, and other basics. If you simply need to power tiny gadgets like these, a smaller and less powerful generator would suffice. Smaller generators with a few hundred watts of power can perform these jobs.

If you want to power larger items like the camper’s refrigerator and microwave, you’ll need a greater wattage generator.

Generators capable of handling these larger objects have a power output ranging from 2,000 to 5,000 watts.

Some generators are specially built to provide more power while remaining quieter than other versions. Because they have the best of both worlds, these generators are typically more expensive.

Direct the exhaust pipes upwards or away from you

The first item to consider while using a generator while camping is the generator’s location. Specifically, the generator’s exhaust end. This side of the generator should always be facing away from your campground.

It is also feasible to direct the exhaust system of some generator models upwards toward the sky. Any of these locations will divert the noise generated by the exhaust squarely away from you.

Move Your Generator A Little Further Away

The second item to consider when deciding how to silence a generator is the distance between it and your campground. This is one of the most critical aspects of keeping your campground quiet when utilizing a generator.

The distance between your generator and your campground will be determined by several variables. The very first thing to keep in mind is whether you’ll be camping in a campsite with designated campsites or in an open space while boondocking.

For instance, whether you’re camping at a park with lesser-sized camping spaces, you should keep your neighbors in mind. You wouldn’t want to annoy your other guests with the sound from the generator, so keep it away from their campground.

If you’re camping in an area without any other people, both the length of your extension cables and how far you prefer to travel are the most important factors to consider. The more distant your generator is from your campground, the quieter it will be.

Most generator manufacturers will display the decibel rating of their specific model. In most cases, these decibel levels are recorded around 7 meters away from the working generator.

If you wish to run in that decibel range, a reasonable rule of thumb is to keep your generator at least 20 feet away from your campsite.

If you have the room and no camping neighbors, buying some massive extra-long extension cables will allow you to position your generator as far away as you like.

By maintaining your generator at least 20 feet away from your campground, you may greatly reduce noise and concentrate on enjoying the outdoors.

Position The Generator On A Soft Surface

Another essential element to consider when determining how to quiet a generator is the surface on which it is left operating. Once you’ve determined a safe distance for your generator, make certain that it’s placed on a surface, which will dampen rather than increase the noise.

It’s advisable to stay away from any hard surfaces. As a result, do not set the generator on wood, concrete, or asphalt, since these surfaces will simply amplify the noise.

Typically, when camping, the best and only alternatives for placing your generator are simply soil or grass. Both of these are excellent options for a surface to set your generator on. Those will absorb and reduce the rumbling generator’s sound.

Assume you don’t even have any softer ground on which to install your generator. Anti-vibration mats are an excellent option in this situation. Anti-vibration mats are often constructed of rubber and aid in the reduction of noise and vibration caused by home equipment.

You may lay a few of these mats beneath your generator to assist reduce the noise produced by vibrations.

Use Sound Deflectors To Keep Your Generator Quiet

After you’ve put your generator on the soft surface distance away from your campsite, the greatest part you can do to quiet it down, even more, is to utilize sound deflectors.

While this may appear to be a complex task, it is rather simple to carry out. It could go a long way toward understanding how to silence a generator as much as feasible.

All you’ll need are four sheets of plywood and one sheet of non-flammable material. Drywall is an excellent choice for this since it is reasonably fire-resistant. Every piece should be approximately 4 feet broad and 3 feet tall.

All of these components may be propped up against the generator at different angles. Make sure you utilize the drywall on the side of the generator where the exhaust is located. You wouldn’t want your deflectors to burn!

By angling these bits of wood around the generator, you allow for airflow whilst deflecting sound waves down into the soil. You may quickly reduce the decibel level of your generator without negatively impacting performance.

Construct An Acoustic Enclosure Or Baffle Box

Building an acoustic enclosure and baffle box is another option comparable to making deflectors. The same explanation that deflectors function well applies to this approach. The enclosure will confine the sound waves and significantly reduce the noise decibels produced by the generator.

The nicest thing about an acoustic enclosure and baffle box is that it is considerably more compact than transporting 5 pieces of plywood in your trailer or RV. Another advantage is that you may buy a baffle box or just construct your own.

If you opt to make your baffle box, the method is pretty simple. A few simple materials are required to construct a baffle box:

  • Wood 2×4’s\sL-brackets
  • The quiet board
  • Sealer for foam

For a short tour, watch this video:

If you do want to use a handmade baffle box, keep in mind that ventilation holes must be included.

This is critical because if there isn’t enough airflow throughout the baffle box enclosure, the temperature will harm the generator. Make holes on the box’s side in which the generator’s exhaust is placed.

Replace The Muffler On Your Generator

Installing a bigger replacement muffler is among the most common ways to quiet a generator. A muffler must, you guessed it, mute the sound originating from the exhaust pipes connected to the generator’s motor.

Perforated tubes within the muffler are meant to deflect vibrations from the engine, lowering the noise that finally leaves the exhaust pipe.

The exhaust pipes are among the generator’s loudest components, second only to the engine itself. You may hope to quiet down the generator by improving the effectiveness of the muffler 10 to 12 decibels.

While changing the muffler on your vehicle or truck may be simple, finding a muffler, which will fit your generator may be challenging. This is because there are many various types of generators on the market, each with a varying size of the exhaust pipe.

Finding a particular muffler that will fit your generator right out of the box is unlikely.

Your best bet is to consult with a qualified technician or small engine repairman. They’ll have quite a better understanding of what options you have for changing the muffler on your generator.

To install an alternative generator with such a muffler, you’ll almost certainly require a bespoke solution.

Make Use Of Water As A Generator Muffler

If the job of installing a new muffler sounds too difficult, you may substitute water. You’ll have to do some tweaking to get this to work.

5 gallons of water pail, a clamp to link a hose to an exhaust pipe are all you’ll need for this. Make sure your generator was higher up than the pail of water.

Don’t let the water running back into the exhaust pipe of your generator. In case you’d rather be especially cautious about water backflow, then you may also puncture a few small holes in your hose.

  • Using the clamp, attach your hose to an exhaust pipe.
  • Then, insert the opposite end of the hose into the puddle of water. The water will function as a muffler for the generator’s exhaust sound.

You may anticipate reducing the generator’s sound level by about 5-7 decibels by utilizing that water muffler approach.

Quick Tips For Making A Generator Quieter

Although these techniques can help decrease noise, your generator is still open and will be loud unless you follow our top eight recommendations. The greatest thing you should do to make a generator quieter is to install an enclosure. When you already own one, we offer some suggestions for making it quieter. Skip forward if you don’t get a portable generator enclosure and want to make a generator noise reduction box.

  • Choose the appropriate size – The more strong the generator, the more sound it produces. Assess your power requirements and choose a generator that provides the appropriate quantity of power. This will help to decrease background noise.
  • Point the exhaust far from you – Help ensure the exhaust is pointing away from you, and even straight up. This will aid in the dissipation of the sound.
  • Maintain a safe distance – Place the generator as far away as possible from you, ideally at least 20 feet. Purchase extra-long, heavy-duty generator exhaust extension cables.
  • Stick on the soft ground, hard surfaces, such as concrete or asphalt, may enhance reverberation and noise. The vibrations will be reduced if the generator is placed in grass or soil. If you can’t locate soft ground, you can use a rubber mat.
  • Construct an enclosure – or improve the one you already have. We’ve observed soundproofing materials lower a generator’s sound levels by more than 20 dB!

What Should You Look For When Purchasing a New Generator?

Assume you decide to look for your new, calmer generator. Did you know exactly what you’re searching for? The majority of individuals do not. As a result, we’ll take a moment to go through something important to look for while looking for your less loud generator.


In general, you’ll want to search for an generator of inverter that has its housing. These are significantly silencer than the bigger, less-enclosed types commonly employed on construction sites and in some emergency circumstances. They are also lighter for you to transport easier.

Power Output vs. Sound Rating

Generally, the more energy a unit has, the noisier it will be. Luckily, RVers don’t require a lot of power. Unless you’d like to operate an air conditioner and a microwave, the 2,000-watt generator must be plenty for your RV needs. A decent, enclosed 2,000-watt generator must only produce 65dB of noise to make it become a fairly quiet alternative.

Those who want to operate items like an A/C, on the other hand, will need more energy than what a 2,000-watt generator can offer. A 3,500-watt unit will be required at that moment.

When you go for an insulated unit, you ought to be able to locate a pretty quiet 3,500-watt generator that is roughly comparable in terms of sound production to the 2,000-watt one.

Of course, the new, ultra-quiet generator may be enclosed with plywood or placed in the generator quiet box for its silence and help it become more unobtrusive.
