When you’re an RVer, a generator is a godsend. It allows you to have electricity everywhere you go, allowing you to operate your air conditioner in the middle of the desert or warm up a cup of coffee in the parking lot of a Walmart.

Even the nicest things in life and generators are no exception, have negatives. What is the most serious problem with generators? They make a lot of noise. In fact, depending on the type of generator, they can be incredibly noisy, making them practically difficult to operate if you have any kind of neighbors.

If you own one of these extremely noisy generators, you may be upset that you can’t put it to good use without disturbing the rest of the neighborhood’s sleep. Fortunately, there are solutions to this issue. You can silence RV generator noise with a little effort—and sometimes a dash of creativity—so that everyone around you may enjoy the peace while you operate your A/C, microwave, or phone charger.

Do you want to know how to make a generator quieter? There are a few distinct choices available. We’ll go over how to quiet a generator in this article so you may travel comfortably and silently no matter where you go.

Methods To Make Your Generator Quiet

Any of the methods listed below can be used to shut off an RV generator.

  • Use a soundproof box if necessary.
  • Use a generator compartment that is soundproof.
  • A muffler is used to make the generator more silent.
  • For generators, use high-damping mounts.
  • Connect two smaller generators in series with one larger generator.

A nice branded RV generator will produce less noise, but if you’re stuck with an old one that was functioning OK but is now creating noise, there are a few things you may try to make it quieter. People experiment with various methods to ensure that the RV generator produces the least amount of noise. A noise level of more than 70 decibels from an RV generator should be deemed disturbing. The noise level of most new branded portable generators will be between 60 and 65 dB. That sounds similar to the noise made by a laptop or a table fan. If you’re stuck with a generator that makes a lot of noise, you can try one of the solutions below to make it quieter.

1. Soundproofing with soundproofing boxes

A soundproofing box or enclosure is one of the techniques to make an RV generator quieter. It is possible to reduce the volume of a noisy RV generator to a decibel level that is acceptable to human ears. The box you’ll build for your RV generator will primarily be constructed of wood and sound dampening or soundproofing material. You must, however, exercise greater caution in Such an enclosure. An expert may assist you in the construction, but make sure you follow specific guidelines if you want to do it yourself.

There must be a way to get the exhaust out. So that exhaust fumes are properly vented and do not collect within An intake opening for a cooling fan or air circulation that does not generate too much heat. A door that is designed and placed so that it is always accessible from your camping site. Sound reflectors can also be utilized, and they should be placed so that sound is reflected away from you. When camping at a campground, though, you may find yourself in a bind because there may be people in every way unless you have that edge point where no one is present in one direction, and you might place the sound there.

It is possible to construct such a sound-dampening enclosure, although it may not work for everyone. You should also consider the financial implications. If you have prior enclosure-building experience, you will be in a stronger position. Alternatively, if you have somebody in your family or acquaintance network who would be willing to do the work for you, remember that while this method may not appear to be as professional as it should be, it does the job for some people. It also depends on the type of sound absorption material you employ.

People are often so irritated by the loudness of their old generator that they just purchase a new, quieter portable generator for their RV. And while that makes sense at times, if you’ve recently bought one and it’s producing a lot of noise, trying this method would be a good idea. But take into account all of the factors mentioned above.

2. Generator compartment soundproofing

It can be challenging to make significant adjustments to the RV generator when installed inside a compartment, and working on the compartment can also be challenging. Because it comes as-is from the manufacturer, any modifications may void the warranty. As a result, you must be sure before making these adjustments. Identifying the source of the noise can assist you in installing noise-absorbing material inside the compartment and reducing the noise.

Adding a resonator to the exhaust or sound-proofing mufflers to the walls are two more things you may do within the compartment. These are approaches that you can try out and see if they work. The first step is to figure out what’s causing the noise in that compartment and then come up with a solution. There are numerous soundproofing professionals who can assist you with this. Rather than attempting this as a DIY project, an expert with prior knowledge should be consulted.

The noise generated in the generator compartment may be loud enough to permeate and disturb you in the RV, as well as annoy your park neighbors. When purchasing a new RV, the compartment may not be wholly soundproofed and may just have basic installations. It may not make a lot of noise at first, but you may run into problems as time goes on. Remember that noise from an RV generator could be caused by various factors, including the noise made by the generator’s fan.

A high-speed fan working within the RV generator can generate enough noise to travel through the generator compartment and into the passenger cabin. Exhaust can also make a lot of noise; depending on how long the pipe is and where it finishes, the noise can easily infiltrate the passenger compartment, necessitating a different solution than simply installing soundproofing material.

3. Quieting the generator with a muffler

The use of a muffler can significantly reduce RV generator noise. This strategy may be effective for some people but not for others. They may not be effective at reducing high noise, but they are effective at reducing low noise. Also, the cost of installing the muffler may deter you from attempting this. This can be done as a do-it-yourself project, but you must be careful not to do anything that would void your RV generator guarantee.

If there isn’t enough muffler, the exhaust pipe will make a noise at engine frequency. If the exhaust pipe does not extend beyond the passenger compartment, the noise will disturb you, and mufflers may be a remedy. If your generator already has a muffler, ensure it’s large enough. If not, you should try to get a larger one for your RV generator.

4. Using high-damping generator mounting

The generator will vibrate at the same frequency as the motor and engine, causing the noise. If the mounts on the generator are correctly calibrated, they can dampen the noise. The mounts are frequently insufficient because they must also be tuned for RV road vibrations. As a result, the noise generated by the generator’s natural vibrations can travel outside of the compartment and bother you.

Often, such noise does not appear in the early stages of use, as the mounts may be capable of handling the changes and eliminating the noise. Check the mounts on the RV generator to see if they are broken or replaced if it is an older model. Using high-quality props can also assist time reducing noise.

5. Rather than using one giant generator, use two smaller generators in tandem.

This strategy is an excellent way to reduce noise while also providing additional benefits. So, how are two generators able to produce less noise? The higher the watts, the more noise is paid; a 5000-watt generator will produce more noise, whereas two smaller watts (say, 2000) will make less noise. Also, there will be times when you do not require the whole 5000 watts of power and can get by with just 2000. As a result, a single 2000 watt generator will emit far less noise. A compact generator, such as this one, produces relatively little noise and is light in weight.

Furthermore, having such a mix is advantageous in handling; they are easy to transport and manage. If you have a travel trailer, you can hook it up to your truck to keep the noise out of the trailer. Also, employing a 5000 watt or higher wattage may not provide complete capacity, and it will always be less than what is available at full capacity.

There are a few other things you can do to keep your RV generator quiet.

  1. If you’re using a portable generator, try positioning it such that the exhaust and inlet pipes are away from where you’re camping.
  2. Make sure the RV generator is not placed on a hardwood surface. Vibrations might cause noise in this situation. Because of this combination, the noise is intensified.
  3. Water can be used as well. The exhaust pipe can be linked with a hose pipe immersed in a few liters of water. Take extra precautions to prevent water from entering the generator.
  4. 4.If your RV generator’s exhaust pipe is horizontal, this could be another reason for the generator’s noise. It can be positioned vertically to lessen noise to some extent.
  5. Invest in a more quiet generator. Yes, if you’re replacing an existing generator that’s creating a lot of noise or is too old, focus on this one factor while you’re shopping for a new generator. Most branded generators are a little more expensive, but they will provide you with peace and quiet. With future technological advancements, you will obtain portable generators that produce the least amount of noise, eliminating the need for any of the above modifications.

What to Look for When Purchasing a Different Generator

Let’s pretend you’ve decided to start looking for a new, quieter generator. Do you have any idea what to look for? The majority of folks do not. As a result, we’re going to spend a few minutes talking about what to look for while searching for a less noisy generator.


In general, you’ll want to seek an inverter generator that has its own enclosure. These are far quieter than the larger, less-enclosed models commonly used on construction sites and emergency circumstances. They’re also lighter, which makes them easier to transport.

Power Output vs. Sound Rating

Generally speaking, the more power a unit has, the noisier it will be. Fortunately, RVers rarely require a lot of energy. A 2,000-watt generator should be enough for your RVing needs unless you need to run the air conditioner or microwave. A good, enclosed 2,000-watt inverter generator should only produce 65dB of noise, making it a relatively quiet option.

However, those who want to run devices like the air conditioner will need more power than a 2,000-watt unit can give. A 3,500-watt generator will be required at that moment. You should be able to locate a reasonably quiet 3,500-watt generator that is roughly similar to a 2,000-watt one in terms of sound output if you choose for an enclosed unit.

Of course, your new whisper-quiet generator can be encased in plywood or housed in a baffle box to reduce noise further and make it more covert. 


As you can see, there are various options for getting power in your RV wherever you are without producing a lot of noise. Try one or all of these suggestions to have a tranquil generator experience that most people consider impossible.
