How loud is a backup generator at a house?



The question of how loud a generator is can be hard to answer. I will start with a sound levels being perspective based. Loud to me may not be loud to you and vice versa. A better way of explaining it is that my wife thinks my snoring is louder than I do. With knowing that my experience is to not try to explain in terms of loud by telling you 65 decibels at 25 feet is how loud the generator is. The unit is sound dampened and with enclosure closed you can have a conversation within 25 feet. That does not give you perspective to the frequency or tone that the motor makes. It is about as loud as your AC unit but it just sounds like a lawnmower.

 

The best explanation is when the unit is running you may think someone is mowing your lawn. Is that loud? I will not try to assume what you consider loud will sound like. I can tell you when no one has power, I sleep better knowing that I have a generator and I do not know the difference between my AC running and the generator running. It's all background noise at that point. My wife says my snoring is worse than the generator but again that is perspective.

 

When buying a generator, it is natural to worry if your neighbor is going to be mad or bothered by your generator.  I also want to be a good neighbor and take it into consideration. In 20 years of installing generators I have had zero complaints from standby generator customers that said a neighbor made them shut the unit down. Zero, not one. While you may think it is going to be loud, I have not found one customer that regretted the purchase of a generator from the noise level.
