What Are the Quietest Generators? – 5 Generators

What Are the Quietest Generators

Due to frequent power outages in the USA, more people are seeking generators for their homes. Generators are also a top need for running power tools at job sites and providing necessary and affordable energy for camping and RVing. But it’s a fact that no one likes loud generators, and there is a reason for it. A noisy generator disturbs your sleep, neighbors, and your camping spree. As a result, quiet generators are much in demand. You may also have a quiet generator at your home but not as quiet as you want, and think of upgrading to a quieter one.

You can now find plenty of quiet generators in the market, and there are some generators that customers rely on blindly for their quietest power output. Although finding one generator that can fulfill all requirements is difficult, you can check out the quietest generators with variable capabilities to fit your needs.

Read the guide given below to find the quiet generators and learn the way to select the quietest generators:

What To Look for When Choosing a Quiet Generator?

What Are the Quietest Generators

As a general rule, a generator that produces more than 80 dB of noise is considered a “loud generator, “and a generator that produces less than 60 dB of noise is considered a “quiet generator.” The quietest generators are usually known as inverter generators, with more consistent and efficient power delivery than traditional generators.

  • Furthermore, many cities and homeowners associations (HOA) do not allow generators with more than 75 dB of sound. And if you run any generator above 75 dB, you may have to give a fine.
  • Generally, for camping sites, you should not run a generator that produces more than 65 dB of sound.

The above-given rules are the ones people generally follow while looking for a quiet generator. They open the specifications for the generators, compare the noise levels of the top-picked generators and find out the one that produces the least amount of sound. This is an important specification to look for while buying a quiet generator, but in practical, you need to look for many other specifications.

For example, in addition to DBS, wattage is also important. A 3000W generator will be quieter than a 10,000W generator. Furthermore, starting and running wattage, tank capacity, and running time of the generator are also important factors to consider. Also, you need to think about the settings for which you need a generator. Let’s have a look at these specifications one by one:

Quietness Of Generator

On the specification list, you will see the noise level of the generator mentioned as:

Noise levels: 68-74 dB

Just reading noise level numbers won’t give you an idea of how loud or quiet a generator is. You need to understand what noise level a generator is producing. To understand this, read the given details to figure out how loud your generator is.

Operating your generator at ¼ (25%) of load will produce the first decibel level (lower sound limit) of noise. So, a 3000W generator will produce 750W power. However, as a generator is usually operated above ¼ load, it produces more noise. A generator makes a second-decibel level (higher sound limit) when operating at full load (100%).

Here is the categorization of generators with different noise levels:

  • Quiet Generators: 50-60 dB
  • Quieter-Than-Average Generators: 60-70 dB
  • Average Noise Generators: 70-80 dB
  • Loud Generators: 80-90 dB or above 90 dB

Breathing produces 10 dB of noise; whispering produces about 30 dB of noise, and refrigerators make 50 dB noise level. So, practically, as we consider a quiet generator is the one with below 60 dB noise level, it would be similar to the noise level of the refrigerator.

On the other hand, a loud generator produces above 75 dB noise; its noise level would be like a truck(80dB) or hairdryer (90 dB).

Wattage Of Generator

Since you are looking for a generator to overcome power outages or go camping, you will look for a generator with enough power to do these tasks. For whole-house power outage, you need a generator with 10,000+ running wattages, and for camping and RVs, you need a 2000-3000W running generator (quiet generator).

So, a small wattage generator will definitely be quieter than a generator running the whole house.

But the question is, how can you differentiate the noise level of two generators with different wattages? Or how would you know which generator is the quietest?

For this purpose, you need to consider the “Watts Per dB†ratio. This will explain how many running watts a generator produces per 1 dB. And that’s how you can estimate which generator is quieter.

Watts Per decibel Ratio = Running Wattage (W) ÷ Noise Levels (dB)

If a generator has 2800W running watt and 49 dB noise level, its Watts per dB ratio will be 58W per dB. This means it will produce 58W per dB.

If a generator has 10,500W running wattage and 74 dB noise level, its Watts per dB ratio will be 135W per dB. This means it will produce 135W per dB. A higher Watts per dB ratio shows that it will produce more wattage per dB.

So, even if a 10,500W generator produces 74dB noise, its 135W per dB shows that it is a quiet generator.

Tank Capacity and Fuel Type

A good generator also needs to have enough tank capacity (gasoline or propane) to run at least for 10 hours. Quiet generators are inverter generators that use gasoline as a fuel source. They may run on gasoline or propane, or both. Dual generators have the advantage of choosing fuel based on your needs. An inverter generator has a tank capacity ranging anywhere from 2-10-gallons. The larger the fuel tank capacity, the longer it will provide gasoline-based power.

Generally, gasoline generators have a 36% longer running time. It’s because the energy density of gasoline is 36% higher than liquid propane energy density. So, the most energy-efficient and quiet generators are inverter gasoline generators.

Weight And Size of Generator

Weight and size are also important factors to consider. Small-sized generators are inverter generators with 40-50 pounds weight that can be easily top-handled or side-handled.

On the other hand, heavy generators weigh up to 100 pounds and have a wheel kit to add portability.

Whatever your preference is, both types of constructions can be brought to the campsite, kept in the garage or placed in the car.

Electric Start

When looking for the quietest generator, an additional electric start feature adds to the user experience. Instead of a pull-cord to start the generator, the modern generator has an electric start that is easy to handle. Electric start can be in the form of a switch, remote control, or push button.

Several Outlets

It is convenient to power multiple devices with multiple outlets as the electrical load can be distributed. Quiet generators have multiple outlets, including RV outlets and USB outlets.

Usually, a quiet generator with at least two household electrical outlets is suggested for evenly and efficiently spreading the electrical load.

Can You Get a Completely Quiet Generator?

You cannot get a completely quiet generator. Every generator will produce some noise, but the level of noise a generator produces decides whether it can be considered quiet or not.

Furthermore, a quiet sound for one person might not be quiet for another. So, a generator listed quiet, will not be the same for everyone.

How To Lower a Generator’s Noise?

If you have an inverter generator, it will already have a lower noise level than a standard generator, but if you still consider it loud, you can try some methods.

You can insulate a generator, keep the generator away from where you will be staying, or cover it with a permanent or semi-permanent fixture.

Are Portable Generators Suitable For Indoor Use?

No, it is not recommended to use portable generators indoors.

Although portable/inverter generators produce clean energy, it doesn’t mean they can be used indoors. They are poisonous and can affect the human lungs.
