Generators can be a fantastic asset to anyone who needs access to power while away from a major source, for example those who are out camping in the middle of nowhere. However, one of the main issues people face when using generators is the noise level.

Quiet Generators: A Buyer’s Guide For 2022

For some people, generator noise is completely palatable and doesn’t bother them in the slightest. For others, however, the need for a quiet generator has never been greater.

Thankfully, there are now plenty of generator models on the market which are built to offer silent or quiet running. Of course, the level of noise emitted by these generators is measured in dB, and generally, you’ll be able to find out the sound rating on generators before you buy. The higher the rating, of course, the louder it is going to be. But what else should you be looking for when it comes to shopping around for the best quiet generator?

Silent generators have plenty of brilliant qualities. In this buying guide, we’ll look closely at the things you need to know before buying while answering a few common questions at the end to help tighten things up.

What Makes a Quiet Generator… Quiet?

Naturally, all power generators are going to need a few staple features to be able to run. It’s a simple fact! However, many of these features and facets can create an awful lot of noise. When shopping for silent or quiet generators, it’s worth looking for factors which are suppressed in the design.

For example, a big cause of noise in everyday generators is the fan, and vibrations which are caused in between parts. These elements are most likely to cause whirring or buzzing noises during operation, which can prove to be quite annoying if, for example, you’re trying to sleep!

Quiet or silent generators will be designed in a particular way to help quash the noise level created by these parts. For example, some quiet generators use inverters, and smaller engines, to reduce noise pollution. Inverter generators tend to be a lot quieter than most, though you may also find some generators which benefit from added acoustics. This means that the sound produced from within is flattened down before being emitted.

Things to Bear in Mind

Before you buy a quiet generator outright, it’s worth taking a moment to consider some of the issues which may impact you after purchase. Here’s a quick rundown.

The Power-Noise Balance

This isn’t always true; however, it’s fairly common to see quiet generators operating on a smaller engine than regular models. It’s just common sense that a small model would make more noise than a larger one! With that in mind, you will have to consider whether or not the trade-off between power and noise is worth it.

While a quiet generator will offer less noise pollution, it won’t necessarily work as hard. Our tip here would be to look at the noise levels suggested by everyday generators and to find a model which offers a relatively low level of pollution.

Fuel Economy

Most quiet or silent generators will, by design, use less fuel due to their size and stature. However, this isn’t always the case. You should look out for generators which offer economy modes or which require very little in the way of fuel in the first instance. Once again, there is also a balance to be found here between fuel economy and power, too.

Engine Speeds

The best quiet or silent generators on the market will at least let you switch up your speed. This means that you’ll be able to choose how much power you need, and how much noise is emitted. These models are perhaps most recommended as they give you greater control from use to use. Need more power? Crank up the speed. Time to quieten down? Switch it down to the slowest settings.


You’ll likely find that many silent and quiet generators will be fairly compact in size and may even be considered fairly portable. Therefore, if you’re in the market for a bigger model, you may need to think about looking at everyday generators. It’s worth remembering, again, that bigger generators are more likely to kick out noise, and what’s more, they are more likely to guzzle fuel. However, smaller generators are less likely to run for as long, or to offer quite as much juice for your money.

Frequently Asked Questions

Let’s take a look at some common questions people ask when buying silent or quiet generators for the first time.

How Much Should I Pay for a Quiet Generator?

As there isn’t really a distinct line of quiet or silent generators as such, you may simply need to look for everyday generators with quieter settings. This means the market is going to vary wildly in terms of price. Models focusing on noise level will likely start at around £150-£200, but do be aware that you may be expected to pay more than £300-£500 for the best or most feature-rich models.

How Quiet Should a Quiet Generator Be?

This all depends on your own noise sensitivity, in general. However, general consensus suggests that any generator running at less than 60dB will be considered very quiet indeed. Most generators will run much louder than this. Bear in mind that over 100db is likely to be very hard on your ears.

Is a Quiet Generator Worth Buying?

That all depends on what your priorities and preferences are. If you are really struggling with a generator that’s fairly noisy, then it will be worth looking at the wider market for silent generators.

However, do remember that there is always likely going to be a trade-off on power consumed and efficiency, too. Keep a close eye on what user reviews have to say.


While there may not be any generators out there which are considered 100% silent, there are plenty which work hard to reduce the running volume. Take a look at what’s out there and don’t be afraid to compare everyday generators for their running noise.
