Choosing the best quiet generator is tricky.

A noise level of 58 decibels may be high for one but low for another person and people are constantly seeking the quietest generator.

Here is the worst-case scenario for a buyer:

Choosing a quiet generator based on noise level while neglecting its power performance.

Since most manufacturers know you are buying the generator based on one factor, they sacrifice performance because you care less about it.

The good news?

It’s 2019, and you can choose a generator that produces less noise but also performs best. Our top 5 list comprise of generators throwing out immense power in a quiet operation.

But before I get ahead of myself, let me share with you something you need to know about generators. And that is:

Why Are Generators So Noisy?

It’s not secret generators produce lots of noise. And that’s why most people are seeking silent generators.

The noise of a generator depends on so many factors. Here’s are some of the factors affecting the sound:

  • The air density
  • The exhaust
  • The cooling fans

All these three things alter the noise of a generator. For a conventional generator, you will have extra things causing noise. Things like:

  • internal fan,
  • current instability,
  • the friction of various parts,
  • mechanical vibrations.

Generators with inverter technology are silent than conventional generators. Since they have a compact design, they use a small engine, which lowers the noise level.

An inverter generator is efficient. That’s because its inverter gen-set produces an electric current.

Besides that, its gen-set body casing lowers the sound. Most inverter generators use insulated sound dampening material that absorbs noise vibration.

That’s why most of these inverter generators have a noise decibel of 10 to 20 than average generators.

Other generators on the market have an acoustic housing that dampens sound, which reduces noise levels.

What Noise Level Should A Silent Generator Have?

Decibel measures the sound. A decibel reading of zero means the threshold of hearing-The lowest sound a human can hear.

For instance, if you are exposed to 160 dBa, it will hurt your eardrums.

In other words, a loud generator is going to have more dBa. Generators differ when it comes to the amount of dBa they produce.

Now to the main question:

How many decibels is a quiet generator supposed to produce?

The most ultra-quiet generator will operate at 50 to 60 dBa or less than that. The best way to know this is to understand the different dBa sound levels. Here’s a table showing you different noise levels.

What Are Some of the Things Making Noise in a Generator?

Noise from a generator comes from two things:

  • Engine vibrators
  • Exhaust system burning the fuel

The first thing is to install the muffler on your generator. Or make sure the generator you are buying has a high-quality muffler.

Most mufflers can reduce generator noise by 10 to 15 decibels of noise.

If you can’t buy a generator with a muffler, you will need an enormous amount of skill on your part to mount the correct piping and adaptors for a lock-free exhaust.

When shopping for a generator that has the right muffler, second, since vibration causes the noise of a generator.

You need to buy a generator that has sound-dampening material. That way, you will experience less noise when the generator is working.

How Engine Size Affects Noise

The engine size of a generator affects noise. And this a tight rope to balance.

The question you need to ask yourself here is: Do you need a quiet generator, or do you want a generator that will power most of your electrical appliances.

A generator with a large engine capacity, means you are getting more power. And more power means more noise.

Likewise, a generator with a small engine will produce less power. And less power means the generator is quiet.

If you can get a small engine throwing out more power like a conventional generator, then you need to buy it because the quietest generators sacrifices on the engine size.

For instance, a generator producing 5000-watt is louder than a generator producing 1000-watts.

In other words, before you decide on whether you should go for a quiet generator.

You first need to calculate the number of watts of every electrical appliance you will use.

Using those figures, you can know in advance whether you will need a quiet generator or you will have to go with the engine size.

Throttle Control (And How it Affect Noise in a Generator)

A smart throttle control will reduce the noise level in a generator. Conventional generators maintain a constant RPM speed despite their load.

The problem with that is, they become loud and less fuel-efficient. If you have a generator’s engine running at a different output level, it will reduce the noise level.

That said, the generator will always vary the engine speed to run the required capacity.

In other words, when your generator is operating at full capacity, you will have the most noise.

But when you decrease the output level, you will have a quiet running generator.

The critical thing here is choosing a generator that changes its noise level depending on the output and not running at constant RPM speed.

5 Ways to Make A Generator Quiet

A loud generator, even a quiet one is hard to ignore. And noise can be irritating sometimes. The good news is, there are five ways to reduce the noise of the generator. Here are some of the things you need to follow through.

Insulate the enclosure

If you have a generator having an enclosure but still the noise is coming out. You can insulate the enclosure. Doing so creates an extra barrier. There are three options to insulate the enclosure:

  • Sound absorbing foam
  • Rubber waffle pads
  • Sound dampening material
  • Acoustic barriers

Doing reduces the noise level. Besides that, placing the rubber waffle pads on the ground and putting the generator on top isolates the vibrations. That’s also something you can do to reduce the noise further.

Build An Enclosure to the Generator

An enclosure housing the generator absorbs and deflects the noise. While doing this, make sure your gen-set gets enough air to burn, airflow to cool, and can get rid of the exhaust.

The second thing is, make sure the exhaust receives enough ventilation. And air circulates freely to prevent overheating.

Above all, the enclosure housing must have enough ventilation. A suitable enclosure will reduce the sound level by 10 decibels.

Extend the distance of Generator

Making a medium distance between your house and the source of noise can help reduce the noise level.

When you increase the distance using a long extension cord, chances are, you will reduce the noise level.

That way, the sound will spread over a large area, and you won’t hear the noise at all.

The rule followed in outdoor open space is:

When you make the distance, you reduce the noise level by 6 decibels.

Besides that, make sure the generator is in a dry and stable place to prevent damage and potential accidents.

Upgrade to An Excellent Exhaust

The exhaust makes a lot of noise in a generator than any other part. When you have a large exhaust pipe, you get additional noise.

That’s why a must for you to upgrade it.

An exhaust is something you can replace with a generator muffler, or if you are mechanical, you can use the car muffler instead.

Attaching the muffler reduces the noise level. Besides that, you will also have to create a custom pipe so you can connect to the exhaust.

Since most exhaust pipes point horizontal, you can expect more noise. Pointing in one direction means more noise.

To minimize the exhaust pipe noise, you can make sure it points vertically so that the sound is directed upwards.

FAQ About Quiet Generators

What happens if I operate my generator at a low load most of the time?

If you operate the generator at a low load (in this case less than ¼ capacity), the generator’s performance will decline over time.

That means reducing its lifespan and you will have to be on the market to buy a new one.

The best solution is to make sure you sometimes operate the generator higher than 50 percent load.

Can I use my generator with an extension cord?

Of course, you can do that. One thing you have to remember is a long cord causes a drop-in voltage.

The voltage will drop by 2 to 3 volts if you have a 10-meter cord. The number of volts doubles as you increase the distance.

Does a generator cause carbon monoxide poisoning?

The engine exhaust of a generator emits carbon monoxide. This is a poisonous gas that kills in seconds. It comes with no smell, no color, and no taste.

That’s why it is essential to use a generator outside and away from windows, doors, and vents. Most importantly, you need to make sure the engine exhaust is directed outside.

If you want to use the generator well, make sure you read the manual. Sometimes, you can install carbon monoxide sensors in your home. These sensors can alert you in case, the oxygen level in your home is low.
