Standby generators are very useful but can create noise that may be unsuited to some people. Here’s what you need to know about standby generator noise levels.
How Loud are Standby Generators?
Under normal loads home standby generators generally create noise ranging from 45 decibels to 75 decibels. This is about the level of a quiet conversation up to an HVAC or washer-dryer.
However, the level of noise created by a standby generator will depend on a variety of factors, including the size and type of generator, and the load it is operating under.
Under heavy loads, larger home and industrial generators can produce noise of 100 decibels or more. Anything above 90 dB is considered “loud” in a typical suburban or country environment.
If there is a power outage, you may need to operate your home backup generator for many days and nights to provide emergency electricity. For extended use, it’s important to keep your generator’s noise level down so you don’t exceed local environmental noise regulations. So quieter standby generators are a necessity, particularly in closely-spaced urban and suburban neighborhoods.
Good Decibel Levels for a Standby Generator
Noise levels of up to 85-90 decibels (dB) maximum are considered good for household standby generators. At this level anybody listening beyond 30 feet away is unlikely to be offended by the noise, and farther out the noise becomse a non-issue. Obviously, anything below this decibel level is better for extended use and tightly-packed neighborhoods.
Here are some good quiet standby generators to check out:

Is 72 dB loud for a generator?
Decibel levels between 65-75 dB are considered quiet for a generator. This is roughly the level of a modern washer-dryer or HVAC unit and is tolerable even in very close proximity.
A standby generator’s distance from the house is important. If your house or your close neighbors are less than 30 feet away from your generator then you want a standby generator that is 72 dB or below.
Generac Standby Generator Noise Levels
