Decibel Rating For Generac Generators

Posted on  by admin

The sound generator makes during operation are measured in Decibel Levels or dBA. The decibel rating chart below represents the numeric figure comparison with the sounds of household appliances, industrial and commercial equipment we recognized and could identify on a daily basis.

Generators today are more than necessary today. With climate change and the unpredictability of or weather patterns we need emergency backup power. Too often we see power get knocked out and people need backup power for their perishable and everyday uses.

A noisy generator can mean the difference in getting a good night sleep or getting up and feeling frustrated about your generator choice of purchase. If you’re going to run high powered tools or on a worksite, noise levels may not be an issue but for homes, camp sites and food trucks, its imperative to consider noise output for your generator.

Decibel Level Comparison Chart is a good Helper

Use the decibel ratings chart above and compare it with the generator you’re considering purchasing.

As always, >visit our Just Portable Generator main home page for a list of generators.

We have over 300+ from a wide spectrum of manufactures, brands, and models. If you’re looking for a solar power stationwith panels, look here. How about solar panels without? Look here on this page. Inverter generators? You can find them here along with dual fuel generators, RV Ready ones, Standby whole house generators and open frame models.

What ever you’re looking for, you’ll be able to find it. The Generac iQ2000 produces an estimated sound level of 62dB while the Westinghouse WH1000i comes in at about 59dB – quiet enough to stand next to and hold a conversation without trying to talk over the generator.

Noise LevelsYour home standby generator won't be running permanently, but if there's a power outage you may need to run it for several days and nights to supply emergency power. When you do, it's likely to emit noise levels ranging from 65 to 100 decibels, which exceeds most noise areas' noise ordinances.

Likewise, how loud is a Generac 8000 watt generator? For its weight, which hovers just below 200 pounds, the Generac 8000 watt generator holds quite a lot of power. GP8000e Generac Generator Specs & Usage Information.

One may chug while another hums loudly. For example, the 65 decibel range may be annoying to some, but normal conversation is rated at 60 decibels. Where should a whole house generator be placed? The most ideal location for generator placement is between the electric meter and the gas meter. If both of the meters are on the same side of the house, the generator can be placed somewhere between the two, allowing the shortest run of both gas and electric.

Generac is one of the best-known manufacturers in the generator industry, and for a good reason. While Generac may not have the name recognition of Honda or Yamaha when it comes to engines, the company has been able to compete on performance at a much lower price over its 60-year history.

When you get the best Generac generator, you can be assured that you’re getting a model that will last and offer all of the features you need. In order to help you find the best Generac generator, we looked through the company’s entire lineup and considered a number of important factors.

First, we looked at different types of generators – conventional and inverter generators, as well as portable and standby generators.

  • All of these generator types are designed for very different purposes.
  • Within each category, we looked at the rated and maximum power output of each model, the types of fuel it is able to run on, and how long each generator can run for.
  • We spent tens of hours reading technical specifications from Generac as well as customer reviews about each of their generators to come up with our five favorite Generac models, highlighted in the table below.
  • After that, you’ll find detailed reviews of each generator, complete with pros and cons.

Our buying guide covers everything you need to know about choosing the right Generac generator for your needs.

Finally, we sum up our three overall favorite generators in Generac’s current lineup.

Generac produces the quietest 8kW and 12kW generators. Among the 20kW generators, Briggs & Stratton currently produces the quietest generator. Some people have complained that their Generac 20kW generators are noisier than the expected 67dB. You must remember that when a generator is tested for noise by the manufacturer, they place it in an open field.

You need to know where the generator will be located in your yard. Walls and other surfaces can amplify a generator’s sound, and a generator’s surroundings have a significant impact on its loudness. Many whole house generators are not enclosed in sound-attenuating structures when they are first installed.

The noise of a generator situated against walls or between buildings will travel further than a generator in an open field.

In North America, typically permitted noise levels during the day are around 60 dB(A) and at night 50 dB(A). However, local laws may vary from region to region.

Generally speaking, a generator should be run without a load once a week to ensure that it is ready to use when you need it. Generac generators are programmed to run in exercise mode on a schedule. They have a Quiet-Test® feature that reduces the weekly test engine speed, reducing the noise level to that of an idling car. In test mode, the engine only runs at two-thirds of its normal revs per minute.

How Generator Noise Is Measured

When an object vibrates, it emits sound waves (essentially pressure waves) into the air. Sound can become painful, uncomfortable, or annoying when the pressure wave’s amplitude exceeds the threshold level. A generator engine has moving parts that cause vibrations in the air around it, making noise.

The decibel (dB) scale describes the sound level. There are two dB scales:

  • dB(L) – measurement is on a linear scale that treats all frequencies as an equal value. The ear is sensitive to ranges between 1,000 to 4,000 Hertz per second.
  • dB(A) – measurement is based on what the human ear hears. The scale is weighted and more accurately reflects what the ear experiences.

The dB(A) scale is the one used for measuring the noise levels of generators. Noise levels from 80 to 100 dB(A) are considered very loud, 100 to 125 dB(A) uncomfortable, and 140 dB(A) causes pain. Some people have a lower noise tolerance than others and may feel pain at lower decibels.

A vacuum cleaner usually runs between 60-85 decibels, while window air conditioners or electric lawn mowers generate between 80-89 decibels. The issue is not only with the decibel levels but also the duration of the sound. A vacuum cleaner running at 67 decibels only has to be tolerated for a few hours, whereas a generator running at 67 decibels continuously for three days is a very different experience. It might annoy you and the neighbors.

Generally speaking, the higher the decibel level, the shorter the human tolerance time.You can listen to a sound at 85 dBA for up to 8 hours. If that sound goes up to 88 dBA, it is safe to listen to it for only 4 hours.

How to Reduce the Noise From a Standby Generator

You can get a variety of enclosures for a standby generator that provides weather protection and sound attenuation. Usually, the sound-attenuating chambers don’t come standard with the generator, and you have to buy them afterward. Sound-attenuated enclosures have adhesive-backed acoustic foam panels that absorb the sound and are resistant to oil and water.


Generac whole house generators are relatively quiet, but it depends on the kind of fuel they use and their size. Generac propane or natural gas-powered generators are quieter than Generac’s diesel-powered generators. When buying a generator, there is always a trade-off between its power output and its noise level.
