What is the Quietest Generator?

Understanding the reasons behind quietly generating electricity will allow you to make the right choice towards choosing the best and quietest portable generator that best fits your needs.

Our best quiet portable generator selection includes some of the best ones. Besides, a large aftermarket exists in advanced noise reduction solutions to achieve the most quiet running generators.

How to Compare the Decibel Levels?

Noise is any undesired sound that is considered annoying, loud, or disruptive to hearing. The sound pressure level is expressed in decibels, dB, or dBA, which measures the intensity of a sound. The higher the dBA of a generator, the louder it is.

For comparison, 0 decibels is the quietest sound that a healthy human ear can hear. Calm breathing is 10 decibels; a whisper conversation is 30 decibels; a normal conversation is 60 decibels. While a vacuum cleaner is 80 decibels and a power saw is 100 decibels.

Over 140 decibels cause pain in the eardrums and might cause hearing damage. So the difference between 0 dB and 140 dB is far more than just numbers.

How to Measure the Sound Level of a Generator?

Sound measurement is a variable metric based on how distant you are from the source of the noise. The standard distance stated by the industry for all generators is 23 feet (7 meters) unless otherwise stated.

When testing portable generators, be sure to measure the noise level from the same distance. As the distance doubles, the sound intensity level will decrease by 6 dB. For example, 65 dBA at 23 feet away will be 59 dBA at 46 feet.

What are the Generator Noise Level Regulations?

There are no universal standards for the amount of permissible noise for generators. Rather, each application and environment in which you are using the generator is different. Therefore, make sure to check the acceptable noise limits in your city or county.

The Environmental Protection Agency (EPA) identifies the acceptable noise levels for different areas. For instance, indoor residential areas, schools, and hospitals are identified with levels of 45 dB. On the other hand, outdoor residential areas, playgrounds, and other outdoor areas where people spend varying amounts of time are identified with levels of 55 dB. Whereas the level of 70 dB is identified for all areas.

Occasional exposure to higher noise levels of 70 dB is moderated with a sufficient amount of moderately quiet time during a 24 hour period. Therefore, prevent any measurable hearing loss over a lifetime.

These guidelines aim to protect our well-being from the environmental noise that can interfere with our daily activities, including having a conversation, sleeping, working, or any other recreational activity.

Audio disturbance in national parks, RV parks, and camping sites is also important. Usually, each place has its own rules regarding the decibel levels of generators. According to the National Park Service (NPS), operating any motorized equipment or machinery (ex. generators) should not exceed 60 dBA when measured from a distance of 50 feet. If you are not close to your neighbors, then you might not have those restraints.

What is a Good Decibel Level for a Generator?

In general, portable quiet generators should have a decibel rating between 50 to 65 dB. This range is the utmost acceptable generator noise level. And if the only difference between two generators is only 3 decibels, don’t think of them lightly. Because, in reality, it will make a big difference. In fact, for every 10-decibel increase in your generator sound level, the noise is doubled. So a generator rated at 70 dB is roughly twice as loud as a generator rated at 60 dB.

Some manufacturers are famous for their super quiet generator engines with very low decibel levels. Such as the Honda EU2200i, which is rated at 57 dB when running flat out..

Standards of the Best Quiet Generators

A generator’s quiet technology depends on many factors. For example, the engine’s size, the quality of the muffler, and whether the motor has an enclosure. These are all major factors that would directly impact the loudness or the quietness of a generator. Not to mention, the quality of the engine. In fact, cheap air-cooled generators are usually not quiet. Quiet generators for whole-house tend to have water-cooled engines. Here is what to consider before purchasing a quiet portable generator.

  • Sound Varies According to the Power Output

One of the main factors affecting a generator’s sound is the size of the engine. Sometimes you may find yourself compromising the power output in order to get a very quiet generator. However, considering the applications you will be powering will allow you to get a whisper-quiet generator within the suitable power range.

More power usually means higher decibel levels, as high as 110 decibels. Sometimes this is going to differ depending on the model of the portable generator. If a couple of inverter generators have the same power output but vary in the noise rating, then this could come down to a better engine. All other things being equal a 10,000 watt unit will be noisier than say a 3,500 watt model.

However, more power will always result in a louder generator. For example, a 2000-watt generator will be less noisy than a 3000-watt generator. Likewise, the decibel level will also always change according to the load required at a time.

  • Significance of Inverter Technology

Inverter generators tend to be significantly quieter than regular generators. This is because the efficiency in which they produce electrical current allows them to have smaller engines, which accordingly reduces the noise levels.

Besides, the body casing of portable generators is another major contributor. Quiet inverter generators are constructed out of insulated, sound dampening materials that absorb the noise vibration produced by the generator. Thus, a portable inverter generator is a solid 10 to 20 decibels quieter than the average conventional generator.

Other silenced generators are available with an enclosed acoustic housing that dampens the sound produced. In this case, the noise is less than an open frame generator. However, inverter generators stand out as the best quiet generators on the market today. Other inverter generators’ attributes are their ability to produce stable power for sensitive electronics and good fuel efficiency.

To learn more about the significance of inverter technology, check our article that explains the difference between inverters and generators.

  • Throttle Control of Quiet Portable Generators

The smart throttle is one of the best features in the top-rated quietest generators. Conventional portable generators run at a constant RPM speed regardless of the load. This makes them not only louder but also less fuel-efficient. The engine’s ability to run at different output levels will remarkably reduce the operating volume. Most inverter generators utilize a throttling system, a fuel economy mode. Hence, they are super quiet and have better fuel efficiency.

With the fuel economy mode, the portable inverter generator automatically varies the engine speed to optimally run the required load. It makes sense that the generator is loudest when it’s running at full load. So, when the output level decreases, you get a generator with an engine that runs quieter.

  • Factors Impacting the Noise Level of Generators

Apart from the size of a generator, the noise produced by the engine depends on several factors. For instance, the air density around portable generators. In addition, the ambient surroundings can affect the sound rating produced by two identical generators. Furthermore, the exhaust, which is a significant contributor to the overall noise level of a generator. Not to mention, the cooling fans, which apart from cooling the system, are also responsible for altering the quietness of a generator during operation. The sound of a cooling fan varies depending on the operating speed and the fan blade design.

However, the sound level of a quiet non-inverter generator is altered due to some other extra factors. Such as the alternator, which has another internal fan that adds to the total noise level. In addition, the current instability of the alternators produces some mechanical noises with changes in load. Also, the structure of these conventional generators gives more space for mechanical vibrations. Due to the friction of various parts and components of the generator, it creates extra mechanical noise.

How to Make Your Generator More Quiet?

Choosing the best portable generator is essential in many cases, because a noisy generator is hard to ignore. You want the best quiet generator within the available budget. First, however, it is essential to understand how noise can spread and how to control it. Below are some of the most effective ways to make your generator quieter:

  • Extend the Distance: Increase the distance of the generator from your activity area. And invest in long extension cords (outdoor rated) and positioning the generator further away.
  • Proper Positioning: Using the leveling rubber feet, stabilize your portable generator to the desired position. While doing this, ensure to point the generator’s exhaust away from your home, campsite, or your neighbors.
  • Upgrade the Exhaust: A standard generator silencer should have a significant effect on the operating sound. Not to mention, long exhaust piping alone provides an additional level of noise reduction. You can also use a car or motorcycle muffler.
  • Move the Exhaust Pipe Vertically: Adjusting the exhaust pipes to point vertically will allow the sound waves to be directed towards up rather than towards occupied areas.
  • Build an Enclosure: Placing the generator in an enclosure will help absorb and deflect the noise. However, you don’t simply put it in an enclosed box. Instead, ensure the generator gets air to burn, enough airflow to stay cool, and can freely get rid of its exhaust.
  • Insulate the Enclosure: If an enclosure alone doesn’t do the trick, then insulate it. For example, you can use rubber waffle pads, sound-absorbing foam, and dampers. Placing the generator on top of sound-absorbing materials or installing acoustic barriers can considerably damp the noise.

If all the above steps didn’t reduce the noise level to a minimal level, then consider upgrading to one of the best quiet generators.

Bottom Line

Today, manufacturers are taking significant steps towards the science of noise reduction of generators. They are controlled by the desire of the consumers to have a more quiet environment. With the growing demand, we tested and compared many quieter generators. In an attempt to find the most quiet generator out there.

With our guide, finding the best and quietest generator that best fits your needs should be an easy job. In addition to the aftermarket strategies towards having a generator that runs quietly.
