The Top 10 Quietest Portable Generators

Most people dislike excessive noise. Ambient humming of a noisy generator is ought to spoil your day, which is why buyers list the noise levels of a generator as one of the key factors they consider before purchasing one.

You should do the same. But which generators are the least noisy?

In this article, I have created an updated, ranked list of 10 most quiet portable generators currently on the (US) market. Unsurprisingly, they are all inverter generators, since low noise levels are one of the advantages they have over conventional units.

Note that the listed units do not include color or other variations of the same device and are only limited to portable generators with publicly listed noise levels. Be our guests and enjoy the reading.

Before proceeding further, make sure to consider (or remember) the following:

  • Decibel (dB), the unit of sound volume, is on a logarithmic scale. This means that the perceived noise does not scale linearly with their value (they do not add up as you would if e.g., adding on weight). Instead, an increase of 10 dB doubles the perceived volume.
  • For the same reason, running two generators in parallel will NOT double their decibel value.
  • Quite unintuitively, running two generators in parallel will also NOT double the perceived volume. Their noise levels increase by roughly 3 dB.
  • Note that some manufacturers don’t list the noise levels of their portable generators and therefore, quieter generators may be out there.
  • Also note that there currently aren’t any measuring standards strictly imposed by US governmental or regulatory bodies for noise emissions of portable generators.
  • Most manufacturers measure the sound levels at 23 feet. However, the load they apply to the generator during the measurement can fluctuate significantly by manufacturer. Accuracy of direct comparison therefore cannot be guaranteed by default.

Without further ado, here is the top 10 quietest portable generators currently on the market!
