They're high power internal combustion engines. Explosions are loud.

Yes. If you run the engine at 3600 rpm to get 60 hertz ac power, it's
a lot "louder" than if you run it at 1800 or 1200 rpm and use the wire
windings to step the frequency up to 60 hertz. This is because high
frequency sound at the same decibels is perceived to be louder than
low frequency sound.


> Are the zoning people smart enough to include noise limits?

It depends. Agricultural and industrial zones don't generally have
noise ordinances. When they do, the ordinances tend to be written as
decibels rather than perceptual disturbance.

Why are gensets loud?

Is there a fundamental physics problem or are they all designed for industrial 
areas where the noise isn't much of a problem?

If I wanted a less noisy one, could I get it?  How much more would it cost?

Are the zoning people smart enough to include noise limits?  ...

What’s not to love about a power company that literally qualifies as a 
recidivist felon?

It is my sincere hope to finish my mortgage and then start putting money 
towards electrical independence. (Wind, more solar, batteries, and 
disconnecting Persistent Graft and Extortion).
